Description

List processing method, device and storage medium

Technical Field

The present application relates to the field of terminal technology, and in particular to a list processing method, device and storage medium.

Background technique

With the development of terminal technology, wearable devices are becoming more and more popular among users. Some wearable devices (such as smart watches) can have a user interface (UI), which can include a variety of UI components, such as button components, list components, digital badge components, etc. Among them, the list component is a commonly used component, such as the file list of the file management application (application, APP), the contact list of the contact APP, the information list of the information APP, etc., all use the list component and display the list content based on the list component.

In some implementations, when a list jump occurs, the wearable device can load the list content of the jump target location, and then jump from the current list content to the list content of the target location for display.

However, the effect of such a list jump is similar to refreshing the page to display the content, which is a poor user experience.

Summary of the invention

The embodiments of the present application provide a list processing method, device and storage medium, which are applied to the field of terminal technology, and are helpful to realize the scrolling effect of list jump and improve user experience on the basis of saving memory and hardware resource overhead of wearable devices.

In the first aspect, the embodiment of the present application proposes a list processing method, which is applied to a wearable device, and the wearable device includes a display screen. The method includes: displaying a first interface on the display screen, the first interface includes a first list element and an index bar, and the first list element is a list element in a preset list; detecting a list jump operation acting on the index bar, and the list jump operation is used to jump to the second list element in the preset list; in response to the list jump operation, displaying the first intermediate list element and the second intermediate list element in sequence on the display screen until the second interface is displayed; wherein the first intermediate list element is one or more list elements between the first list element and the second list element and close to the first list element, and the second intermediate list element is one or more list elements between the first list element and the second list element and close to the second list element; the second interface includes the second list element. In this way, during the list jump process, in addition to the first list element at the jump start position and the second list element at the jump target position, the smart watch can sequentially display some list elements between the first list element and the second list element in the preset list, so that the list elements to be displayed can be loaded based on the memory and hardware resource overhead of the wearable device. And by displaying the first middle list element, the second middle list element and the second list element in sequence, a list scrolling effect can be achieved during the list position jump process, thereby improving the user experience.

In one possible implementation, the first intermediate list element includes N consecutive list elements adjacent to the first list element in a preset list; and/or the second intermediate list element includes M consecutive list elements adjacent to the second list element in the preset list; N and M are both integers greater than 0.

In a possible implementation, the first interface further includes part or all of the first intermediate list elements; and/or the second interface further includes part or all of the second intermediate list elements.

In a possible implementation, the index bar includes a plurality of index elements arranged in sequence, and the list jump operation includes an operation of clicking the first index element in the index bar.

In a possible implementation, after detecting a list jump operation acting on an index bar, the method further includes:

According to the first position of the first list element in the preset list and the second position of the second list element in the preset list, determine the list jump direction, which includes jumping up and jumping down; according to the list jump direction, determine the position offset value of the first position and the second position; according to the list jump direction and the position offset value, determine multiple intermediate list elements between the first position and the second position in the preset list, and the intermediate list elements include the first intermediate list element and the second intermediate list element. In this way, by selecting a part of the list elements in the preset list as intermediate list elements through the list jump direction and the position offset value, it can be ensured that based on the hardware conditions such as the memory of the smart watch, the display of multiple intermediate list elements can be realized, and then the sliding effect can be realized based on the multiple intermediate list elements.

In a possible implementation, the list jump direction is downward jump; according to the list jump direction and the position offset value, multiple intermediate list elements between the first position and the second position are determined in the preset list, including: if the position offset value is greater than the preset number, then in the preset list, a first number of list elements after the first position and a second number of list elements before the second position are determined as intermediate list elements; if the position offset value is less than or equal to the preset number, then in the preset list, multiple list elements between the first position and the second position are determined as intermediate list elements. When there are fewer list elements between the first position and the second position, the list elements between the first position and the second position are determined as intermediate list elements; when there are more list elements between the first position and the second position, the continuous multiple list elements below the first position and the continuous multiple list elements above the second position between the first position and the second position are determined as intermediate list elements, so that when the target list elements are displayed in sequence later, the list elements can be scrolled down from the first position, and after scrolling through the continuous multiple list elements, they are finally scrolled to the second list element for display. At the same time, this scrolling effect can only load a small number of list elements, so it can be achieved based on the memory and hardware conditions of the wearable device.

In a possible implementation, the list jump direction is upward jump; according to the list jump direction and the position offset value, multiple intermediate list elements between the first position and the second position are determined in the preset list, including: if the position offset value is greater than the preset number, the third number of list elements before the first position and the fourth number of list elements after the second position are determined as intermediate list elements in the preset list; if the position offset value is less than or equal to the preset number, multiple list elements between the first position and the second position are determined as intermediate list elements in the preset list. When there are fewer list elements between the first position and the second position, the list elements between the first position and the second position are determined as intermediate list elements; when there are more list elements between the first position and the second position, the continuous multiple list elements above the first position and the continuous multiple list elements below the second position between the first position and the second position are determined as intermediate list elements, so that when the target list elements are displayed in sequence later, the effect of the list elements scrolling upward from the first position can be generated, and after scrolling through the continuous multiple list elements, the second list elements are finally scrolled to display. At the same time, this scrolling effect can only load a small number of list elements, so it can be achieved based on the memory and hardware conditions of the wearable device.

In a possible implementation, a first intermediate list element and a second intermediate list element are displayed in sequence on a display screen until a second interface is displayed, including: loading multiple target list elements into the memory of a wearable device in sequence, the target list elements including a first intermediate list element, a second intermediate list element, and a second list element; determining coordinate information of each target list element; determining a jump distance based on the coordinate information of the first list element and the coordinate information of the second list element; and displaying each target list element in sequence based on the jump distance.

In an embodiment of the present application, a first list element, a plurality of first intermediate list elements, a plurality of second intermediate list elements, and a second list element are loaded into the memory of a wearable device to be spliced into a list to be displayed, in which only a small number of list elements in a preset list are included in the list to be displayed, and the first list element and the second list element are spliced into a list displayed sequentially. Then, the jump distance is determined based on the coordinate information of the first list element and the coordinate information of the second list element, and each target list element is displayed in sequence on the display screen based on the jump distance, so that the effect of sliding from the first list element, passing through some intermediate list elements, and then sliding to the second list element can be effectively displayed on the display screen.

In a possible implementation, each target list element is displayed in sequence according to the jump distance, including: dividing the jump distance into multiple segments to obtain multiple single movement distances; moving the coordinate information of each target list element by a first single movement distance according to the list jump direction to obtain the coordinate information of each target list element after the movement; obtaining the visible vertical coordinate range corresponding to the display screen; displaying the target list element whose coordinate information after the movement meets the first condition corresponding to the visible vertical coordinate range in the display screen according to the coordinate information after the movement, and removing the target list element whose coordinate information after the movement does not meet the first condition from the memory; repeatedly performing the operation of moving the coordinate information of each target list element by the next single movement distance according to the list jump direction, and displaying or removing the target list element according to the coordinate information after the movement, until the second list element is completely displayed in the display screen. In this way, the jump distance is divided into multiple single movement distances, and the first list element, each intermediate list element, and the second list element are moved by the single movement distance in sequence according to the list jump direction. When the single movement distance is small, the movement of each list element can be made smoother.

In a possible implementation, the visible vertical coordinate range corresponds to a first endpoint value and a second endpoint value, and the second endpoint value is greater than the first endpoint value; the coordinate information includes: the first vertical coordinate value corresponding to the lower edge of the target list element, and the second vertical coordinate value corresponding to the upper edge of the target list element; the first condition is: the first vertical coordinate value is greater than the first endpoint value of the visible vertical coordinate range, and the second vertical coordinate value is less than the second endpoint value of the visible vertical coordinate range.

In a possible implementation, multiple target list elements are loaded into the memory of the wearable device, including: determining the target list elements that are not loaded into the memory in the target list elements according to the target list elements that are loaded into the memory of the wearable device; and sequentially loading the target list elements that are not loaded into the memory into the memory according to the order of the list elements in a preset list. After determining the target list elements, some of the target list elements have been loaded into the memory of the wearable device and do not need to be loaded again. Only the target list elements that are not loaded into the memory need to be loaded, so as to reduce the hardware resource overhead of the wearable device.

Detailed ways

In order to clearly describe the technical solutions of the embodiments of the present application, some terms and technologies involved in the embodiments of the present application are briefly introduced below:

1) List width and list height: can also be referred to as list visible width and list visible height. In the embodiment of the present application, the list visible width may refer to the width of the display screen of the wearable device, and the list visible height may refer to the height of the display screen of the wearable device. The list within the range of the list width and list height is a visible list. In the embodiment of the present application, a smart watch is used as an example for illustrative explanation. Of course, the embodiment of the present application is also applicable to other wearable devices, such as bracelets, etc. As long as the list can be displayed, the embodiment of the present application does not specifically limit the type of wearable device.

Exemplarily, FIG1 shows a schematic diagram of a contact list interface. Taking a smart watch as an example, when the smart watch detects the user's startup operation for the contact APP, the smart watch can display the interface shown in FIG1. As shown in FIG1, the contact list interface is displayed on the display screen 100 of the smart watch. In the current example, the list content visible in the contact list interface may include: controls corresponding to "contacts", controls corresponding to "favorite contacts", controls 101 corresponding to the contact "Ayi", controls 102 corresponding to the contact "Ayi" and index bar 103. Among them, the control 101 corresponding to the contact "Ayi" may include the contact name "Ayi" and its corresponding avatar, the control 102 corresponding to the contact "Aiyi" may include the contact name "Aiyi" and its corresponding avatar, and the index bar 103 may include letter indexes such as index #, index A, index B, and an extendable button 1031.

In a possible implementation, when rendering the visible list, all list elements within the visible list width and visible list height range are rendered. Each list element has its own height and width, so the visible list can be rectangular, for example.

However, the display screen may have different shapes in different products. For example, in the example of FIG. 1 , the shape of the display screen is the inscribed circle of a rectangle formed by the list height and the list width. Alternatively, the shape of the display screen may be any shape such as an ellipse, a rectangle, an irregular shape, etc.

It can be understood that, subject to the shape of the display screen, the visible list of the rectangle may not be fully displayed in the display screen, for example, there may be some edge parts that are not displayed in the display screen, but these undisplayed parts are still rendered. For example, in the example of Figure 1, the avatar in the control 102 corresponding to the contact "Ai Yi" at the edge of the display screen 100 is only partially displayed, which is because of the shape of the display screen 100, resulting in the incomplete display of the avatar. As shown in Figure 1, in the embodiment of the present application, an x-axis and a y-axis are provided to measure the location of the list content, with the upper left corner of the display screen 100 as the origin, the horizontal direction is set to the x-axis, and the horizontal right is the positive direction of the x-axis; the vertical direction is set to the y-axis, and the vertical downward is the positive direction of the y-axis. The list width is in the x-axis direction, and the list height is in the y-axis direction. Of course, in actual implementation, the x-axis and y-axis used to measure the location of the list content can have other different settings, and the location of the list content can also be measured in other ways, and the embodiment of the present application is not specifically limited to this.

2) List elements: List elements can also be called list items, and list elements can be the display content in the list. Each list element is independent, each list element has its width and height, and when each list element is loaded into the memory of the wearable device, its position coordinates in the coordinate system corresponding to the display screen can be determined for the list element, and the position coordinates can include abscissas (x-axis direction) and ordinates (y-axis direction). After the list elements are loaded into the memory, the wearable device can send the list elements in the memory to its own display screen for display. Exemplarily, FIG2 shows a schematic diagram of a contact list interface. Taking a smart watch as an example, the content displayed in the interface can refer to FIG1, which will not be repeated here. As shown in FIG2, each row (or each item) of content in the list can be a list element, for example, the control corresponding to "Contact" is a list element, the control corresponding to "Favorite Contact" is a list element, and the control corresponding to the contact "Ayi" is a list element.

It should be noted that if a part of a list element is displayed within the visible list range, the list element can be considered to be within the visible list range. For example, taking the coordinate system in Figure 1 as an example, when the coordinate corresponding to the bottom edge of the list element is greater than 0, and the coordinate corresponding to the top edge of the list element is less than the list height, the list element can be considered to be within the visible list range.

In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

In the embodiments of the present application, "at least one" refers to one or more, and "more than one" refers to two or more. "And/or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and/or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character "/" generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, a-b, a-c, b-c, or a-b-c, where a, b, c can be single or multiple.

It should be noted that the "at..." in the embodiment of the present application can be the instant when a certain situation occurs, or can be a period of time after a certain situation occurs, and the embodiment of the present application does not specifically limit this. In addition, the display interface provided in the embodiment of the present application is only an example, and the display interface can also include more or less content.

With the development of terminal technology, wearable devices are becoming more and more popular among users. Some wearable devices (such as smart watches) may have a user interface (UI), which may include a variety of UI components, such as button components, list components, digital badge components, etc. Among them, the list component is a commonly used component, such as the file list of the file management application (application, APP), the contact list of the contact APP, the information list of the information APP, etc., all use the list component and display the list content based on the list component.

On some interfaces containing long lists, an index bar is provided, and the index bar includes multiple indexes. In some implementations, the user can click an index to make the interface jump from the current list position to the list position corresponding to the index.

Exemplarily, Fig. 3 shows a schematic diagram of an interface for jumping to a contact list. Taking a smartwatch as an example, the interface shown in a of Fig. 3 may include a list element corresponding to "contacts", a list element corresponding to "favorite contacts", a list element corresponding to contact "阿一", a list element corresponding to contact "艾一" and an index bar 301, wherein the index bar 301 includes an index "#", letters or symbols such as indexes "A" to "Z", and a retractable button 3011.

In the interface shown in a of FIG. 3 , when the smartwatch detects a user trigger operation on index "D" in index bar 301, the list jumps to the list position corresponding to index "D", and the smartwatch may display the interface shown in b of FIG. 3 . As shown in b of FIG. 3 , the interface may include a list element 302 corresponding to the index letter "D", an index indication "D" 303, a list element corresponding to contact "Ding Yi", a list element corresponding to contact "Ding Er", and an index bar. Among them, index indication "D" 303 may disappear after the jump is completed, and reappear the next time a jump occurs. Index indication "D" 303 is used to prompt that the current page has been jumped to the contact page corresponding to index "D".

It is understandable that the implementation of jumping from one position in the list to another position described above can provide a good user experience if the list elements in the jumping process can be displayed with a scrolling effect during the jumping process. If you want to display each list element with a scrolling effect during the jumping process, then load each list element and then display it.

However, due to the size requirements of wearable devices, insufficient hardware performance of wearable devices, and limited memory resources, the wearable devices cannot load all list elements during the jump process. Therefore, in the prior art, when implementing list jumps, the list elements at the jump target position are usually loaded, and then the list elements at the target position are jumped from the current list elements for display. This jump method is equivalent to refreshing the content displayed on the page, and the scrolling effect during the jump process is not shown on the page, which will lead to a poor user experience during the list jump process.

In view of this, an embodiment of the present application provides a list processing method, which splices these list elements into a list to be displayed by loading the current list element, the list element between the current list element and the list element indicated by the list jump operation, the set number of list elements near the current list element, the set number of list elements near the list element indicated by the list jump operation, and the list element indicated by the list jump operation. Because the number of list elements included in the spliced list is relatively small, it is possible to scroll and display each list element in the spliced list. At the same time, because the spliced list includes the current list element and its nearby list elements, as well as the list element indicated by the list jump operation and its nearby list elements, it is possible to show the effect of jumping from the current list element to the list element indicated by the list jump operation with a scrolling effect. Therefore, in the embodiment of the present application, the wearable device can use less memory and hardware resource overhead to achieve the list scrolling effect when the list position jumps.

For example, Figure 4 is a schematic diagram of a scenario applicable to the embodiments of the present application. As shown in Figure 4, the wearable device 400 can be a smart wearable device that can be worn by a user and can process corresponding user services and intelligently interact with the user, such as a smart watch, a smart bracelet, smart glasses, etc.

The wearable device 400 may include a display screen 401, on which a list may be displayed. The list may be, for example, a contact list, or a music play list, a music collection list, or a reading list, etc. The embodiment of the present application does not limit the specific implementation of the list displayed on the display screen.

In display screen 401, when the wearable device detects a jump operation of the user on the list, the wearable device 400 can display the list elements in the jump process on display screen 401 based on the list processing method provided in the embodiment of the present application. The embodiment of the present application takes the wearable device 400 as a smart watch as an example for exemplary description.

Exemplarily, the list processing method may include: displaying a first interface on a display screen, the first interface including a first list element and an index bar, the first list element being a list element in a preset list; detecting a list jump operation acting on the index bar, the list jump operation being used to jump to a second list element in the preset list; in response to the list jump operation, sequentially displaying a first intermediate list element and a second intermediate list element on the display screen until a second interface is displayed; wherein the first intermediate list element is one or more list elements between the first list element and the second list element that are close to the first list element, and the second intermediate list element is one or more list elements between the first list element and the second list element that are close to the second list element; and the second interface includes the second list element. Displaying some list elements in the preset list sequentially in this way can not only save the memory and hardware resource overhead of the wearable device, but also realize the list scrolling effect when the list position jumps, thereby improving the user experience.

For example, Fig. 5 shows a schematic diagram of the hardware structure of a wearable device provided in an embodiment of the present application. The wearable device may include a processor 510, a mobile communication module 520, a wireless communication module 530, a display screen 540, a charging management module 550, a power management module 551, a battery 552, an internal memory 560, and an audio module 570, etc.

It is understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the wearable device. In other embodiments of the present application, the wearable device may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

The following, in conjunction with the accompanying drawings, describes in detail the technical solutions of the embodiments of the present application and how the technical solutions of the embodiments of the present application solve the above-mentioned technical problems with specific embodiments. The following specific embodiments can be implemented independently or in combination with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

FIG6 is a flow chart of a list processing method provided in an embodiment of the present application. The method can be applied to a wearable device, and the wearable device can include a display screen. As shown in FIG6 , the method can include:

S601: Displaying a first interface on a display screen, wherein the first interface includes a first list element and an index bar, and the first list element is a list element in a preset list.

In an embodiment of the present application, a first interface can be displayed on the display screen, and a list with multiple list elements can be displayed on the first interface. The list here can be, for example, a contact list, or a music play list, a music collection list, or a list of applications for a smart watch, etc. The embodiment of the present application does not limit the specific implementation of the list displayed on the first interface, and it can be implemented according to actual needs.

Based on the above description, it can be determined that, because the screen size is limited, only part of the list is displayed in the first interface. Regardless of the type of list, there is a complete preset list, which includes all list elements.

For example, for a list of contact types, its complete preset list can be understood in conjunction with Figure 7. Exemplarily, Figure 7 shows a schematic diagram of a contact preset list provided in an embodiment of the present application. As shown in Figure 7, the complete preset list of contacts can include all contacts, as well as some system preset list elements, such as the "Contacts", "Favorite Contacts" introduced above, and 1,000 list elements corresponding to each index letter. In the actual implementation process, the list elements specifically included in the preset list can be selected and set according to actual needs, and the embodiment of the present application does not limit this.

Exemplarily, the preset list can be stored in the memory of the smart watch. When the list elements in the preset list need to be displayed, the list elements to be displayed are loaded from the memory of the smart watch to the internal memory of the smart watch, and then sent to the display screen for display.

In the embodiment of the present application, the first list element may be the first list element displayed in the first interface, that is, the first list element of the visible list in the first interface. Alternatively, in other possible implementations, the first list element may also be the last list element displayed in the first interface, which is not limited in the embodiment of the present application.

In the embodiment of the present application, the index bar can be used to indicate the position of the list jump. The index bar can be a column or multiple columns of multiple index elements arranged in order with an index function. The index elements can be any form such as numbers, letters, strokes or phonetic sequences. The embodiment of the present application does not specifically limit the form of the index elements. The smart watch can jump to the position of the list element indicated by the click operation based on the user's click operation on the index element in the index bar. In the embodiment of the present application, the index elements in the index bar are illustrated as letters, which does not constitute a limitation on the embodiment of the present application.

S602: A list jump operation on the index bar is detected, where the list jump operation is used to jump to a second list element of a preset list.

The second list element may be a list element corresponding to the jump position indicated by the list jump operation. Exemplarily, it can be understood in conjunction with FIG. 7 and FIG. 8, FIG. 8 shows a schematic diagram of a list interface provided by an embodiment of the present application. For the interface shown in FIG. 8, please refer to FIG. 3 a for the content of the interface, which will not be repeated here. Assuming that the interface shown in FIG. 8 is the first interface, and assuming that the arrangement of the list elements displayed in the interface shown in FIG. 8 in the preset list is shown in FIG. 7, the first list element is the list element corresponding to "Contact", and when the smart watch detects a list jump operation acting on the index "Z" 801 on the index bar, the second list element may be, for example, the list element corresponding to the letter "Z" in FIG. 7, that is, the 998th list element illustrated in FIG. 7. Or the second list element may also be, for example, the 999th list element illustrated in FIG. 7, that is, the list element corresponding to the first contact among the multiple contacts under the letter "Z" in FIG. 7. Or, for example, it may also be any contact under the letter "Z" in FIG. 7, which is not specifically limited in the embodiment of the present application.

In the embodiment of the present application, when the list needs to jump to a certain position, the user can input a list jump operation for the list displayed on the first interface, wherein the list jump operation can be a click operation for a specific letter on the index bar.

S603: In response to a list jump operation, the first intermediate list element and the second intermediate list element are displayed in sequence on the display screen until a second interface is displayed; wherein the first intermediate list element is one or more list elements between the first list element and the second list element and close to the first list element, and the second intermediate list element is one or more list elements between the first list element and the second list element and close to the second list element; the second interface includes the second list element.

In a possible implementation, in response to a list jump operation, the first interface of the smart watch may sequentially display a first middle list element, a second middle list element, and a second list element.

In an embodiment of the present application, the first intermediate list element may include N consecutive list elements adjacent to the first list element in a preset list, and the second intermediate list element may include M consecutive list elements adjacent to the second list element in the preset list, where N and M are both integers greater than 0.

Exemplarily, it can be understood with reference to FIG. 7 , assuming that “B” in FIG. 7 is the first list element described above, and assuming that the list jump operation is a click operation on the index “Z” on the index bar, then the second list element can be, for example, “Z” in FIG. 7 , and assuming that both N and M are 4. Referring to FIG. 7 , the four consecutive list elements of contact “Bai Yi”, contact “Bai Er”, contact “Bai San”, and contact “Bin Yi” between the first list element and the second list element and close to the first list element can be understood as the first intermediate list elements in the current example. Later, in response to the list jump operation, for example, the smart watch can display these four first intermediate list elements in sequence.

And, after the first intermediate list element is displayed, the second intermediate list element is displayed in sequence. Referring to FIG. 7 , the four consecutive list elements "Y", contact "Yang Yi", contact "You Yi" and contact "Yu Er" between the first list element and the second list element and close to the second list element can be understood as the second intermediate list elements in the current example. Later, in response to a list jump operation, for example, the smart watch can display the four second intermediate list elements in sequence immediately after displaying the first intermediate list element.

And, after the display of the second intermediate list element is completed, the smart watch then displays the second list element.

The above example introduces the situation where the list jumps downward. The following is an exemplary introduction to the situation where the list jumps upward in conjunction with Figure 7. As shown in Figure 7, assuming that the contact "Zhang Yi" in Figure 7 is the first list element introduced above, and assuming that the list jump operation is a click operation on the index "B" on the index bar, the second list element can be "B" in Figure 7, and assuming that N and M are both 3. Referring to Figure 7, the three consecutive list elements "Z", contact "Yu Er" and contact "You Yi" between the first list element and the second list element and close to the first list element can be understood as the first intermediate list elements in the current example. Later, in response to the list jump operation, for example, the smart watch can display these three first intermediate list elements in sequence.

And, after the first middle list element is displayed, the second middle list element is displayed in sequence. Referring to FIG. 7 , the three consecutive list elements "白三", contact "白二", and contact "白一" between the first list element and the second list element and close to the second list element can be understood as the second middle list element in the current example. Then, for example, in response to a list jump operation, the smartwatch can display the three second middle list elements in sequence immediately after displaying the first middle list element.

And, after the display of the second intermediate list element is completed, the smart watch then displays the second list element.

It should be noted that the list elements displayed in sequence may be list elements in a preset list loaded from the memory of the wearable device to the internal memory of the wearable device for display.

Based on the above introduction, it can be determined that the first interface is displayed on the display screen, and the first interface may also include some or all of the first intermediate list elements. When the wearable device detects a list jump operation acting on the index bar of the first interface, the interface on the display screen changes, that is, the first intermediate list element, the second intermediate list element are displayed in sequence, until the second list element is displayed. At this time, the interface on the display screen may be the second interface, that is, the second interface includes the second list element, and the second interface may also include some or all of the second intermediate list elements.

The following is an exemplary description of the first interface and the second interface in list jumping.

Exemplarily, taking the contact list in a smartwatch as an example, FIG9 shows a schematic diagram of an interface before and after a list jump provided by an embodiment of the present application. The interface shown in a of FIG9 may be a first interface, which may include a list element corresponding to the contact "甲一", a list element corresponding to the contact "甲二", a list element corresponding to the contact "姜一", and an index bar. The contacts included in the interface shown in a of FIG9 may be understood as contacts corresponding to the index "J".

In the interface shown in a of FIG. 9 , it is assumed that the smart watch detects a list jump operation of the user for index “S”. At this time, the smart watch responds to the list jump operation and controls the list to jump to the position corresponding to index “S”.

In the current example, the first list element displayed on the current interface, that is, the list element corresponding to the contact "甲一", can be, for example, the first list element introduced above. And the list element corresponding to the letter "S" corresponding to the index corresponding to the jump position can be, for example, the second list element introduced above.

Since the second list element is after the first list element, the list jumps downward at this time. After displaying the first middle list element and the second middle list element in sequence, for example, the smart watch can display the interface shown in FIG. 9 b, which can be understood as the second interface described above. Referring to the interface shown in FIG. 9 b, the list element 901 corresponding to the letter index "S" itself is displayed in the interface, wherein the list element 901 is the second list element in the current embodiment.

It can be understood that, in the process of the list jumping downward, the first list element, the first middle list element, the second middle list element and the second list element slide upward in sequence and are displayed in the interface of the display screen, that is, the process of the list jumping downward is actually the process of the list sliding upward.

It should be noted that after the second list element is displayed on the display screen, the list may continue to slide upward until the second list element is displayed at the top of the display screen.

For example, in the interface shown in FIG. 9 b, after the list element 901 (i.e., the second list element) corresponding to the index "S" itself is displayed on the display screen, the list continues to slide upward until the list element corresponding to the contact "Ran Yi" and the list element corresponding to the contact "Ran Er" slide out of the display screen, that is, outside the visible range, and the list element 901 corresponding to the index "S" itself and the last two list elements of the list element also slide upward in sequence until the list element 901 corresponding to the index "S" itself is displayed at the top of the display screen, and the display screen displays the interface shown in FIG. 9 c. In the interface shown in FIG. 9 c, at this time, the list element corresponding to the contact "Ran Yi" and the list element corresponding to the contact "Ran Er" have slid out of the display screen, that is, outside the visible range, the list element 901 corresponding to the index "S" itself is displayed at the top of the display screen, and the list element corresponding to the contact "Shi Yi" and the list element corresponding to the contact "Su Er" are also displayed on the display screen. At this time, the jump ends and the list stops sliding upward. Therefore, a jump from the first list element to the second list element is achieved, and during the jump, the first middle list element, the second middle list element and the second list element are displayed in sequence, so that the jump of the list elements can be achieved with a sliding effect.

Exemplarily, still taking the contact list in a smart watch as an example, Figure 10 shows a second interface schematic diagram before and after a list jump provided in an embodiment of the present application. The interface shown in a of Figure 10 is similar to that introduced in a of Figure 9 above, and will not be repeated here. This interface can be the first interface.

In the interface shown in a of FIG. 10 , it is assumed that the smart watch detects a list jump operation of the user for index H. At this time, the smart watch responds to the list jump operation and controls the list to jump to the position corresponding to index H.

In the current example, the first list element displayed on the current interface, that is, the list element corresponding to the contact "甲一", can be, for example, the first list element introduced above. And the list element corresponding to the letter "H" corresponding to the jump position can be, for example, the second list element introduced above.

Since the second list element is before the first list element, the list jumps upward at this time. After the jump, the smartwatch can display the interface shown in FIG. 10 b, which can be the second interface. The list element 1001 corresponding to the letter index "H" itself is displayed in the interface, where the list element 1001 is the second list element in the current embodiment. Therefore, the jump from the first list element to the second list element is realized, and the first middle list element, the second middle list element and the second list element are displayed in sequence during the jump, so that the jump of the list elements can be realized with a sliding effect.

In an embodiment of the present application, a first interface is displayed on a display screen, the first interface includes a first list element and an index bar, and the first list element is a list element in a preset list; when a list jump operation acting on the index bar is detected, the list jump operation is used to jump to a second list element in the preset list; in response to the list jump operation, the first intermediate list element and the second intermediate list element are sequentially displayed on the display screen until the second interface is displayed; wherein the first intermediate list element is one or more list elements between the first list element and the second list element and close to the first list element, and the second intermediate list element is one or more list elements between the first list element and the second list element in the preset list and close to the second list element; the second interface includes the second list element. In this way, during the list jump process, in addition to the first list element at the jump start position and the second list element at the jump target position, the smart watch can sequentially display some list elements between the first list element and the second list element in the preset list, so that the list elements to be displayed can be loaded based on the memory and hardware resource overhead of the wearable device. And the first intermediate list element, the second intermediate list element and the second list element are sequentially displayed, so that the list scrolling effect during the list position jump process can be achieved, thereby improving the user experience.

Based on the embodiments introduced above, it can be understood that in order to display each first intermediate list element and each second intermediate list element in sequence on the screen of the wearable device, it is necessary to first determine each intermediate list element. Therefore, the internal implementation of determining the intermediate list elements is introduced below.

In a possible implementation, after detecting a list jump operation acting on an index bar, the method of the present application may further include:

According to the first position of the first list element in the preset list and the second position of the second list element in the preset list, a list jump direction is determined, and the list jump direction includes upward jump and downward jump; according to the list jump direction, a position offset value between the first position and the second position is determined; according to the list jump direction and the position offset value, a plurality of intermediate list elements between the first position and the second position are determined in the preset list, and the intermediate list elements include a first intermediate list element and a second intermediate list element.

In an embodiment of the present application, when the smart watch detects a list jump operation, it obtains the first position of the first list element displayed on the first interface in the preset list, and obtains the second position of the second list element corresponding to the list jump operation in the preset list.

Here, the position of the list element in the preset list is first described. In a possible implementation, the position of the list element in the preset list can be, for example, the sequence number of the list element in the preset list. The sequence number can indicate the number of the list element in the preset list.

In an embodiment of the present application, the first position of the first list element in the preset list can be the sequential number of the first list element in the preset list, and the second position of the second list element in the preset list can be the order of the second list element in the preset list.

For example, it can be understood in conjunction with FIG. 7. As shown in FIG. 7, it is assumed that there are 1000 list elements in the preset list, and each list element has its own sequence number. Assuming that the first list element is the list element corresponding to "阿一" shown in FIG. 7, it can be determined that the first list element is the third list element in the preset list, and therefore it can be determined that the first position in the current example is 3.

And assuming that the second list element is the list element corresponding to “张一” in FIG. 7 , it can be determined that the second list element is the 999th list element in the preset list, and therefore it can be determined that the second position in the current example is 999.

In the embodiment of the present application, the position of the list element actually identifies the order of the list element in the preset list. Therefore, if the second position is greater than the first position, that is, the order of the second position is after the order of the first position, it can be explained that the list jump direction is to jump downward. If the second position is less than the first position, that is, the order of the second position is before the order of the first position, it can be explained that the list jump direction is to jump upward.

After the list jump direction is determined, a position offset value between the first position and the second position may be determined according to the list jump direction.

In a possible implementation, if the list jump direction is downward, the difference between the second position and the first position can be determined as the position offset value. Alternatively, if the list jump direction is upward, the difference between the first position and the second position can be determined as the position offset value.

Alternatively, it can be understood that the position offset value in the embodiment of the present application may be the absolute value of the difference between the first position and the second position.

For example, assuming that the first position is 355 and the second position is 777, because the second position is greater than the first position, it can be said that the list jump direction is a downward jump, and the position offset value at this time is the difference between the second position and the first position, which is 422; assuming that the first position is 777 and the second position is 355, because the second position is less than the first position, it can be said that the list jump direction is an upward jump, and the position offset value at this time is the difference between the first position and the second position, which is 422.

After determining the list jump direction and the position offset value, multiple intermediate list elements between the first position and the second position can be determined in the preset list according to the list jump direction and the position offset value, and the intermediate list elements include the first intermediate list element and the second intermediate list element.

It is understandable that the list jump operation is to instruct the list elements displayed in the display screen to jump from the first position to the second position. However, because there may be a lot of list elements between the first position and the second position, due to the limited memory resources of the smart watch, it may be impossible to load all of these list elements into the memory and thus fail to display them completely, or cause the system to freeze after all of them are loaded into the memory. Therefore, in the embodiment of the present application, the number of intermediate list elements between the first position and the second position determined in the preset list is less than or equal to the preset number. The specific value of the preset number can be selected according to actual needs.

In the embodiment of the present application, the number of determined intermediate list elements is limited, that is, only a part of the list elements between the first position and the second position are selected as intermediate list elements. By selecting a part of the list elements, it can be ensured that based on the hardware conditions such as the memory of the smart watch, multiple intermediate list elements can be displayed, and then a sliding effect can be achieved based on multiple intermediate list elements.

In an embodiment of the present application, for example, between the first position and the second position, multiple list elements adjacent to the first position (that is, first intermediate list elements) and multiple list elements adjacent to the second position (that is, second intermediate list elements) can be determined as intermediate list elements.

Exemplarily, for example, if the first position is 3 and the second position is 999, that is, there are many list elements between the first list element and the second list element, then multiple intermediate list elements can be determined between the 3rd list element and the 999th list element.

For example, if the first position is 3 and the second position is 7, that is, there are fewer list elements between the first list element and the second list element, assuming that the number of list elements between the first list element and the second list element is less than the preset number, then for example, the list elements between the third list element and the seventh list element can be determined as the middle list elements. The specific method of determining the middle list elements will be described in detail in subsequent steps and will not be repeated here.

In an embodiment of the present application, after a list jump operation acting on an index bar is detected, the list jump direction is determined according to the first position of the first list element in the preset list and the second position of the second list element in the preset list, and the list jump direction includes upward jump and downward jump; according to the list jump direction, the position offset value of the first position and the second position is determined; according to the list jump direction and the position offset value, multiple intermediate list elements between the first position and the second position are determined in the preset list, and the intermediate list elements include the first intermediate list element and the second intermediate list element. In this way, by selecting a part of the list elements in the preset list as intermediate list elements through the list jump direction and the position offset value, it can be ensured that based on the hardware conditions such as the memory of the smart watch, the display of multiple intermediate list elements can be realized, and then the sliding effect can be realized based on the multiple intermediate list elements.

The following is an introduction to the implementation method of determining the middle list elements.

In a possible implementation, when the list jump direction is downward jump, determining the plurality of intermediate list elements between the first position and the second position in the preset list according to the list jump direction and the position offset value may include:

If the position offset value is greater than a preset number, in the preset list, a first number of list elements after the first position and a second number of list elements before the second position are determined as middle list elements;

If the position offset value is less than or equal to a preset number, then in the preset list, a plurality of list elements between the first position and the second position are determined as middle list elements.

The first quantity and the second quantity may be the same or different, and this embodiment of the present application does not specifically limit this.

In a possible implementation, when the position offset value is greater than a preset number, that is, when there are more list elements between the first list element and the second list element, some list elements are selected between the first list element and the second list element so that the final determined intermediate list elements are less than or equal to the preset number.

Furthermore, in order to ensure that the scrolling effect is expressed as continuously scrolling down from the first list element to the second list element, in the embodiment of the present application, a first number of continuous list elements after the first position (that is, the first middle list element) and a second number of continuous list elements before the second position (that is, the second middle list element) are specifically selected. In the actual implementation process, the specific values of the first number and the second number can be selected according to actual needs.

For example, it can be understood in conjunction with FIG. 11. For example, FIG. 11 shows a schematic diagram 2 of a preset list of contacts provided in an embodiment of the present application. As shown in FIG. 11, the preset list may include 1000 list elements. Assuming that in the current example, the preset number is 6, and the first number and the second number are both 3.

Then referring to FIG. 11 , assuming that the first position N is 1 in FIG. 11 , and the second position M is 998 as shown in FIG. 11 , that is, it is currently possible to jump from the position of the 1st list element to the position of the 998th list element.

Because in the example of FIG11 , the second position M is greater than the first position N, it can be determined that in the current case, the list jump direction is downward jump. And the position offset value in the current example is 997, which is greater than the preset number 6.

Therefore, in the preset list, the three list elements after the first position N, that is, the N+1th list element, the N+2th list element, and the N+3th list element, and the three list elements before the second position M, that is, the M-1th list element, the M-2th list element, and the M-3th list element, can be determined as intermediate list elements. Among them, the three list elements after the first position N, that is, the N+1th list element, the N+2th list element, and the N+3th list element are the first intermediate list elements, and the three list elements before the second position M, that is, the M-1th list element, the M-2th list element, and the M-3th list element are the second intermediate list elements.

In the example of FIG. 11 , the determined six middle list elements include: the second list element, the third list element, the fourth list element, the 995th list element, the 996th list element, and the 997th list element.

In a possible implementation, when the position offset value is less than or equal to a preset number, that is, when there are fewer list elements between the first list element and the second list element, multiple list elements between the first position and the second position can be determined as intermediate list elements in the preset list.

For example, it can be understood in conjunction with Figure 12. For example, Figure 12 shows a schematic diagram 3 of a contact preset list provided in an embodiment of the present application. As shown in Figure 12, the preset list may include 1000 list elements. Assume that in the current example, the preset number is 6.

Then referring to FIG. 12 , assuming that the first position N is 1 in FIG. 12 , and the second position M is 5 as shown in FIG. 12 , that is, it is currently possible to jump from the position of the 1st list element to the position of the 5th list element.

Because in the example of FIG12 , the second position M is greater than the first position N, it can be determined that in the current case, the list jump direction is downward jump. And the position offset value in the current example is 4, which is less than the preset number 6.

Therefore, in the preset list, the list elements between the first position N and the second position M can be determined as middle list elements.

In the example of FIG. 12 , the determined multiple middle list elements include: the second list element, the third list element, and the fourth list element.

It should be noted that, for the case where there are fewer list elements between the first list element and the second list element, the middle list elements can be divided equally to obtain the first middle list element and the second middle list element. For example, if there are 4 middle list elements, then the 2 middle list elements close to the first list element are the first middle list elements, and the 2 middle list elements close to the second list element are the second middle list elements. Alternatively, the first middle list element and the second middle list element can also be randomly determined by the middle list elements. For example, if there are 4 middle list elements, then the 3 middle list elements close to the first list element are the first middle list element, and the 1 middle list element close to the second list element is the second middle list element. In the actual implementation process, for the case where there are fewer list elements between the first list element and the second list element, the specific number of the first middle list elements and the second middle list elements can be selected according to actual needs.

In the embodiment of the present application, when the list jump direction is downward jump, if the position offset value is greater than the preset number, then in the preset list, the first number of list elements after the first position and the second number of list elements before the second position are determined as middle list elements; if the position offset value is less than or equal to the preset number, then in the preset list, multiple list elements between the first position and the second position are determined as middle list elements. When there are fewer list elements between the first position and the second position, the list elements between the first position and the second position are determined as middle list elements; when there are more list elements between the first position and the second position, the continuous multiple list elements below the first position and the continuous multiple list elements above the second position between the first position and the second position are determined as middle list elements, so that when the target list elements are displayed in sequence later, the list elements can be scrolled down from the first position, and after scrolling through multiple continuous list elements, they are finally scrolled to the second list element for display. At the same time, this scrolling effect can only load a small number of list elements, so it can be achieved based on the memory and hardware conditions of the wearable device.

In another possible implementation, when the list jump direction is an upward jump, determining a plurality of intermediate list elements between the first position and the second position in the preset list according to the list jump direction and the position offset value may include:

If the position offset value is greater than a preset number, in the preset list, a third number of list elements before the first position and a fourth number of list elements after the second position are determined as middle list elements;

If the position offset value is less than or equal to a preset number, then in the preset list, a plurality of list elements between the first position and the second position are determined as middle list elements.

The third quantity and the fourth quantity may be the same or different, and this embodiment of the present application does not specifically limit this.

In a possible implementation, when the position offset value is greater than a preset number, that is, when there are more list elements between the first list element and the second list element, some list elements can be selected between the first list element and the second list element so that the final determined intermediate list elements are less than or equal to the preset number.

Furthermore, in order to ensure that the scrolling effect is presented as continuously scrolling upward from the first list element to the second list element, in the embodiment of the present application, the third number of continuous list elements before the first position (that is, the first middle list element) and the fourth number of continuous list elements after the second position (that is, the second middle list element) are specifically selected. In the actual implementation process, the specific values of the third number and the fourth number can be selected according to actual needs.

For example, it can be understood in conjunction with FIG. 13. For example, FIG. 13 shows a schematic diagram 4 of a preset list of contacts provided in an embodiment of the present application. As shown in FIG. 13, the preset list may include a preset list of 1000 list elements. Assuming that in the current example, the preset number is 6, and the third number and the fourth number are both 3.

Then referring to FIG. 13 , assuming that the first position N is 998 in FIG. 13 , and the second position M is 1 as shown in FIG. 13 , that is, it is currently possible to jump from the position of the 998th list element to the position of the 1st list element.

Because in the example of FIG13 , the second position M is smaller than the first position N, it can be determined that in the current case, the list jump direction is upward jump. And the position offset value in the current example is 997, which is greater than the preset number 6.

Therefore, in the preset list, the three list elements before the first position N, that is, the N-1th list element, the N-2th list element, and the N-3th list element, and the three list elements after the second position M, that is, the M+1th list element, the M+2th list element, and the M+3th list element, can be determined as intermediate list elements. Among them, the three list elements before the first position N, that is, the N-1th list element, the N-2th list element, and the N-3th list element are the first intermediate list elements, and the three list elements after the second position M, that is, the M+1th list element, the M+2th list element, and the M+3th list element are the second intermediate list elements.

In the example of FIG. 13 , the determined six middle list elements include: the 997th list element, the 996th list element, the 995th list element, the 4th list element, the 3rd list element, and the 2nd list element.

In a possible implementation, when the position offset value is less than or equal to a preset number, that is, when there are fewer list elements between the first list element and the second list element, multiple list elements between the first position and the second position can be determined as intermediate list elements in the preset list.

For example, it can be understood in conjunction with Figure 14. For example, Figure 14 shows a schematic diagram 5 of a contact preset list provided in an embodiment of the present application. As shown in Figure 14, the preset list may include a preset list of 1000 list elements. Assume that in the current example, the preset number is 6.

Then referring to FIG. 14 , assuming that the first position N is 998 in FIG. 14 , and the second position M is 995 as shown in FIG. 14 , that is, it is currently possible to jump from the position of the 998th list element to the position of the 995th list element.

Because in the example of FIG14 , the second position M is smaller than the first position N, it can be determined that in the current case, the list jump direction is upward jump. And the position offset value in the current example is 3, which is smaller than the preset number 6.

Therefore, in the preset list, the list elements between the first position N and the second position M can be determined as middle list elements.

In the example of FIG. 14 , the determined multiple middle list elements include: the 997th list element and the 996th list element.

It should be noted that, for the case where there are fewer list elements between the first list element and the second list element, the middle list elements can be divided equally to obtain the first middle list element and the second middle list element. For example, if there are 4 middle list elements, then the 2 middle list elements close to the first list element are the first middle list elements, and the 2 middle list elements close to the second list element are the second middle list elements. Alternatively, the first middle list element and the second middle list element can also be randomly determined by the middle list elements. For example, if there are 4 middle list elements, then the 3 middle list elements close to the first list element are the first middle list element, and the 1 middle list element close to the second list element is the second middle list element. In the actual implementation process, for the case where there are fewer list elements between the first list element and the second list element, the specific number of the first middle list elements and the second middle list elements can be selected according to actual needs.

In the embodiment of the present application, when the list jump direction is downward jump, if the position offset value is greater than the preset number, then in the preset list, the third number of list elements before the first position and the fourth number of list elements after the second position are determined as middle list elements; if the position offset value is less than or equal to the preset number, then in the preset list, multiple list elements between the first position and the second position are determined as middle list elements. When there are fewer list elements between the first position and the second position, the list elements between the first position and the second position are determined as middle list elements; when there are more list elements between the first position and the second position, the continuous multiple list elements above the first position and the continuous multiple list elements below the second position between the first position and the second position are determined as middle list elements, so that when the target list elements are displayed in sequence later, the list elements can be scrolled up from the first position, and after scrolling through multiple continuous list elements, they are finally scrolled to the second list element for display. At the same time, this scrolling effect can only load a small number of list elements, so it can be achieved based on the memory and hardware conditions of the wearable device.

In a possible implementation, sequentially displaying the first middle list element and the second middle list element on the display screen until the second interface is displayed may include:

S1: Load multiple target list elements into the memory of the wearable device, the target list elements including a first intermediate list element, a second intermediate list element and a second list element; and determine the coordinate information of each target list element.

In the embodiment of the present application, the list elements to be displayed need to be loaded into the memory before they can be displayed. Therefore, after determining multiple target list elements, the multiple target list elements can be loaded into the memory of the wearable device. At the same time, when the list elements are loaded into the memory, the coordinate information of the list elements can be determined.

In an embodiment of the present application, the coordinate information of the list element may include a ordinate and a horizontal coordinate, wherein the ordinate may be the ordinate corresponding to the center point of the top edge of the list element, and the horizontal coordinate may be the horizontal coordinate corresponding to the center point of the top edge of the list element. Exemplarily, FIG15 shows a second schematic diagram of a list interface provided by an embodiment of the present application. For example, in the example of FIG15 , the coordinate information of the list element corresponding to the contact "阿一" has a ordinate of y ₂ shown in FIG15 , and a horizontal coordinate of x ₁ shown in FIG15 .

Alternatively, the ordinate corresponding to the center point of the bottom edge of the list element may be used as the ordinate of the list element. For example, in the example of FIG. 15 , the coordinate information of the list element corresponding to the contact “阿一” has the ordinate y ₁ shown in FIG. 15 .

Take the ordinate of the list element, which is the ordinate _y2 corresponding to the center point of the top edge of the list element, as an example. The implementation method of determining the coordinate information of the list element is introduced below in conjunction with FIG15. As shown in FIG15, assuming that "Contacts" is the top list element and the list element is fully displayed, the ordinate of the list element corresponding to "Contacts" is 0. Alternatively, if only a portion of the top list element is displayed, the ordinate of the top list element is a negative number.

At the same time, the height of each list element is recorded. Assuming that the height of the list elements corresponding to "Contacts" and "Favorites" in the interface shown in FIG15 is 1 centimeter (cm), the ordinate of the list element corresponding to "Favorites" is the sum of the ordinate of the list element corresponding to "Contacts" and the height of the list element corresponding to "Contacts", that is, 1 cm. The ordinate y ₂ of the list element corresponding to the contact "Ayi" is the sum of the heights of the list element corresponding to "Favorites" and the list element corresponding to "Favorites", that is, 2 cm.

Therefore, it can be understood that when determining the coordinate information of the list element newly loaded into the memory, the coordinate information of the last list element in the memory can be used to determine the coordinate information of the list element newly loaded into the memory in combination with the height of the last list element in the memory.

It is understandable that the coordinate information of each target list element can change as the list slides. For example, in the interface shown in FIG15 , assuming that the list slides up by 1 cm, so that the ordinate of “Favorite Contacts” is 0, the ordinate _y2 of the list element corresponding to the contact “Ayi” is correspondingly reduced by 1 cm. At this time, the list element “Contacts” has slid out of the visible list range, and the smart watch can delete the list element “Contacts” from the memory of the smart watch.

Based on the above introduction, it can be determined that some of the first intermediate list elements among the multiple target list elements can be the list elements displayed in the first interface. It can be understood that the list elements displayed in the first interface have been loaded into the memory. Therefore, when loading each target list element into the memory, it is only necessary to load the target list elements that have not been loaded into the memory into the memory.

For example, it can be understood in conjunction with Figure 16. For example, Figure 16 shows a schematic diagram of list elements loaded when a list jumps downward provided in an embodiment of the present application. In the example of Figure 16, it is assumed that the list jump direction is to jump downward, and it is assumed that the determined first intermediate list elements include those shown in Figure 16: "甲二", "姜一", "姜二", and the second intermediate list elements include those shown in Figure 16: "S", "沈一", "盛三". "甲一" in Figure 16 is the first list element, and "T" is the second list element.

In combination with Figure 16, it can be determined that the three list elements "甲一", "甲二" and "姜一" have been displayed on the display screen, that is to say, these three list elements have been loaded into the memory. Then it can be determined that the target list elements that have not been loaded into the memory include: the first middle list element: "姜二", the second middle list element: "S", "沈一", "盛三" and the second list element "T".

At the same time, the current list jump direction is downward, so the five list elements can be loaded into the memory in order from small to large in the preset list. At the same time, it can be understood that the list elements loaded into the memory can be displayed, but because the screen size is limited, the newly loaded list elements are temporarily in the invisible area, and after the subsequent list elements are moved, they can be displayed on the display.

Another example can be understood in conjunction with FIG. 17. illustratively, FIG. 17 shows a schematic diagram of list elements loaded when a list jumps upward provided in an embodiment of the present application. In the example of FIG. 17, it is assumed that the list jump direction is to jump upward, and it is assumed that the determined first intermediate list elements include those shown in FIG. 17: "Ji San", "Ji Yi", and "J", and the second intermediate list elements include those shown in FIG. 17: "Hu San", "Hu Yi", and "Han Er". "Jia Yi" in FIG. 17 is the first list element, and "H" is the second list element.

In combination with Figure 17, it can be determined that the list element "甲一" has been displayed on the display screen, that is, this list element has been loaded into the memory, then it can be determined that the target list elements that have not been loaded into the memory include: the first middle list element: "吉三", "吉一", "J", the second middle list element: "胡三", "胡一", "韩二" and the second list element "H". These 7 list elements.

At the same time, the current list jump direction is upward, so the 7 list elements can be loaded into the memory in order from large to small in the preset list. At the same time, it can be understood that the list elements loaded into the memory can be displayed, but because the screen size is limited, the newly loaded list elements are temporarily in the invisible area, and after the subsequent list elements are moved, they can be displayed on the display.

Based on the above introduction, it can be determined that the first intermediate list elements that have not been loaded into the memory can be determined in the target list elements according to the target list elements loaded in the memory of the wearable device; according to the order of the list elements in the preset list, the first intermediate list elements that have not been loaded into the memory are loaded into the memory in sequence.

In the embodiment of the present application, the target list elements that have not been loaded into the memory are determined according to the target list elements that have been loaded into the memory of the wearable device; the middle list elements that have not been loaded into the memory and the second list elements are sequentially loaded into the memory according to the order of the list elements in the preset list. After determining the target list elements, some target list elements have been loaded into the memory of the wearable device and do not need to be loaded again. Only the target list elements that have not been loaded into the memory need to be loaded, so as to reduce the hardware resource overhead of the wearable device.

S2: Determine the jump distance according to the coordinate information of the first list element and the coordinate information of the second list element.

The jump distance is the absolute value of the difference between the coordinate information of the first list element and the coordinate information of the second list element in the list to be displayed, which is composed of the first list element, multiple first intermediate list elements, multiple second intermediate list elements, and the second list element in sequence. The difference in coordinate information here can specifically refer to the difference in ordinate.

Exemplarily, the list elements loaded by the list jumping downward can be as shown in Figure 16, where the first list element is the list element corresponding to the contact "甲一", and the second list element is the list element corresponding to the index letter "T". The jump distance is the value obtained by subtracting the vertical coordinate of the list element corresponding to the index letter "T" from the vertical coordinate of the list element corresponding to the contact "甲一".

Exemplarily, the list elements loaded by the list jumping upward can be as shown in Figure 17, where the first list element is the list element corresponding to the contact "甲一", and the second list element is the list element corresponding to the index letter "H". The jump distance is the value obtained by subtracting the vertical coordinate of the list element corresponding to the contact "甲一" from the vertical coordinate of the list element corresponding to the index letter "H".

S3: Displaying each target list element in sequence on the display screen according to the jump distance.

After determining the jump distance, in a possible implementation, the jump distance is divided into multiple segments, so that the list to be displayed, which is composed of the first list element, multiple first intermediate list elements, multiple second intermediate list elements, and the second list element in sequence, slides one segment at a time. The sliding of the list to be displayed is the movement of the list elements in the list. The more segments the jump distance is divided into, the smaller the sliding distance of each segment is. The smaller the sliding distance, the smoother the movement of each list element in the list to be displayed. During the sliding process, the first list element, multiple first intermediate list elements, multiple second intermediate list elements, and the second list element will be displayed in sequence on the display screen. For the list elements that slide outside the display screen after display, that is, outside the visible list range, the wearable device will delete them from the memory.

In an embodiment of the present application, a first list element, a plurality of first intermediate list elements, a plurality of second intermediate list elements, and a second list element are loaded into the memory of a wearable device to be spliced into a list to be displayed, in which only a small number of list elements in a preset list are included in the list to be displayed, and the first list element and the second list element are spliced into a list displayed sequentially. Then, the jump distance is determined based on the coordinate information of the first list element and the coordinate information of the second list element, and each target list element is displayed in sequence on the display screen based on the jump distance, so that the effect of sliding from the first list element, passing through some intermediate list elements, and then sliding to the second list element can be effectively displayed on the display screen.

In a possible implementation, the above step S3 may include:

The jump distance is divided into multiple segments to obtain multiple single movement distances; according to the list jump direction, the coordinate information of each target list element is moved by the first single movement distance to obtain the coordinate information of each target list element after the movement; the visible vertical coordinate range corresponding to the display screen is obtained; the target list elements whose coordinate information after the movement meets the first condition corresponding to the visible vertical coordinate range are displayed on the display screen according to the coordinate information after the movement, and the target list elements whose coordinate information after the movement does not meet the first condition are removed from the memory; the operation of repeatedly moving the coordinate information of each target list element by the next single movement distance according to the list jump direction, and displaying or removing the target list elements according to the coordinate information after the movement, is repeated until the second list element is completely displayed on the display screen.

The visible vertical coordinate range may be a vertical coordinate range corresponding to a visible list within a list height and a list width, and the visible vertical coordinate range may correspond to a first endpoint value and a second endpoint value, and the second endpoint value is greater than the first endpoint value.

In the embodiment of the present application, the first endpoint value and the second endpoint value may be the coordinates corresponding to the upper and lower edges of the display screen, and the second endpoint value is greater than the first endpoint value. The embodiment of the present application is described by taking the first endpoint value as the coordinates corresponding to the upper edge of the display screen and the second endpoint value as the coordinates corresponding to the lower edge of the display screen as an example, and the example does not constitute a limitation on the embodiment of the present application.

In the embodiment of the present application, the coordinate information may also include a first ordinate value corresponding to the lower edge of the target list element and a second ordinate value corresponding to the upper edge of the target list element. The second ordinate value corresponding to the upper edge of the target list element may be the ordinate corresponding to the center point of the top edge of the target list element, and the first ordinate value corresponding to the lower edge of the target list element may be the ordinate corresponding to the center point of the bottom edge of the target list element.

It can be understood that the difference between the first ordinate value and the second ordinate value is actually the height of the target list element.

For example, for a coordinate system in which the y-axis is vertically downward as the positive direction, for example, in the coordinate system shown in FIG15 , assuming that y ₁ represents the first ordinate value and y ₂ represents the second ordinate value, then y ₁ =y ₂ +d can be determined. For another example, for a coordinate system in which the y-axis is vertically upward as the positive direction, assuming that y ₁ represents the first ordinate value and y ₂ represents the second ordinate value, then y ₁ =y ₂ -d can be determined. For another example, for a coordinate system in which the y-axis is vertically upward as the positive direction, assuming that y ₁ represents the second ordinate value and y ₂ represents the first ordinate value, then y ₂ =y ₁ -d can be determined.

In the actual implementation process, whether to use the first ordinate value _y1 as the ordinate of the target list element or to use the second ordinate value _y2 to indicate the ordinate of the target list element can be selected according to actual needs.

In a possible implementation, the jump distance is divided into multiple segments to obtain multiple single movement distances. In the specific division, for example, the jump distance can be equally divided into multiple segments, for example, 50 pixels as a unit, to obtain multiple single movement distances, each of which has a movement distance of 50 pixels. Alternatively, the jump distance can be unequally divided into multiple segments to obtain multiple single movement distances.

In the embodiment of the present application, there is no restriction on the division of the jump distance and the specific length of each single moving distance, which can be selected according to actual needs. It is understandable that if the single moving distance is relatively small, the scrolling effect of the list will be relatively smooth. If the single moving distance is relatively large, the scrolling effect of the list will be relatively jumpy.

It is understandable that the movement of each single moving distance must be completed in sequence. The following first introduces the first single moving distance.

In one possible implementation, when the second position is greater than the first position, that is, when the list jumps downward, moving each target list element upward can achieve the effect of jumping downward. Therefore, each target list element can be first moved upward by a first single moving distance, and the first ordinate value and the second ordinate value of each target list element are both subtracted from the first single moving distance to obtain the first ordinate value and the second ordinate value of each target list element after moving.

Alternatively, when the second position is smaller than the first position, that is, when the list jumps upward, moving each target list element downward can achieve the effect of jumping upward. Therefore, each target list element can be first moved downward by the first single moving distance, and the first ordinate value and the second ordinate value of each target list element are added to the first single moving distance to obtain the moved ordinate of each target list element.

Regardless of the moving direction, after determining the vertical coordinate of each target list element after the move, that is, the second vertical coordinate value, it can be determined whether the coordinate information of the target list element after the move meets the first condition.

Exemplarily, the target list elements whose coordinate information after movement satisfies the first condition, that is, the target list elements whose first ordinate value after movement is greater than the first endpoint value of the visible ordinate range (the lower edge is below the top of the display screen), and whose second ordinate value is less than the second endpoint value of the visible ordinate range (the upper edge is above the bottom of the display screen), are the list elements that are still displayed on the display screen after movement, or can also be the list elements that are newly displayed on the display screen after movement. For these target list elements, the target list elements can be displayed on the display screen according to the coordinate information after movement.

And, the target list elements whose coordinate information after movement does not meet the first condition, that is, the target list elements whose first ordinate value after movement is less than or equal to the first endpoint value of the visible ordinate range (the lower edge is above the top of the display screen), or the target list elements whose second ordinate value is greater than or equal to the second endpoint value of the visible ordinate range (the upper edge is below the bottom of the display screen), that is, the list elements that are pushed out of the display screen after movement. For these target list elements, they are removed from the memory. After the first single moving distance is completed, each target list element also obtains new coordinate information, then the operation of moving the next single moving distance can be continued, and the operation of displaying or removing the target list elements according to the coordinate information after the move can be performed until the movement corresponding to the last single moving distance is completed and the second list element is completely displayed on the display screen.

Because the jump distance between the first list element and the second list element is divided into multiple single movement distances in the embodiment of the present application, the second list element will be displayed on the display screen after the last single movement distance is completed.

Exemplarily, FIG18 shows a schematic diagram of displaying list elements in sequence during a downward jump of a list provided in an embodiment of the present application.

In the example of FIG. 18 , as shown in a of FIG. 18 , after the wearable device detects the user's click operation on the index "T", the wearable device can determine the following list elements: "甲一", "甲二", "姜一", "姜二", "S", "沈一", "盛三", and "T". Among them, "甲一" is the first list element, "T" is the second list element, and the rest are middle list elements. Afterwards, the above-mentioned first list element, middle list element, and second list element can be loaded into the memory of the wearable device. When each of the above-mentioned list elements has not been moved, its display status is shown in a of FIG. 18 , and the three list elements "甲一", "甲二", and "姜一" have been displayed on the display screen, and the five list elements "姜二", "S", "沈一", "盛三", and "T" are located in the invisible area.

Also, assuming that the first endpoint value of the visible vertical coordinate range corresponding to the display screen is 0, and the second endpoint value is the list height s, then the condition for the visibility of the list elements in the embodiment of the present application is: the second vertical coordinate value corresponding to the upper edge is greater than 0, and the first vertical coordinate value corresponding to the lower edge is less than s.

Assuming that the value obtained by subtracting the ordinate of the first list element from the ordinate of the second list element is the jump distance d, the jump distance d is divided into n segments to obtain n segments of single movement distances D ₁ , D ₂ , D ₃ . . . D _n .

In the diagram shown in a of FIG18 , it is assumed that the second ordinate value of the first list element “甲一” is 0, and the first single movement distance D ₁ is equal to the height of the first list element. Then, the coordinate information of the first list element, each middle list element, and the second list element are all moved upward by the first single movement distance D ₁ , that is, the first ordinate value and the second ordinate value of the first list element, each middle list element, and the second list element are all subtracted by the first single movement distance D ₁ , and the diagram shown in b of FIG18 is obtained.

At this time, the second ordinate value of the list element corresponding to the contact "甲一" is -D ₁ , which is less than 0, and the sum of the second ordinate value -D ₁ of the list element corresponding to the contact "甲一" and the height of the list element corresponding to the contact "甲一" is 0, that is, the first ordinate value of the list element corresponding to the contact "甲一" is 0, so it can be determined that the list element corresponding to the contact "甲一" has been moved out of the visible ordinate range. Therefore, the wearable device removes the list element corresponding to the contact "甲一" from the memory. The list element corresponding to the contact "甲二" also moves up by D ₁ , and its second ordinate value becomes 0, that is, the list element corresponding to the contact "甲二" becomes the first list element in the visible list.

And, in the diagram shown in a of FIG18 , it is assumed that the second ordinate value of the list element corresponding to the contact “Jiang Er” is the list height s, after moving upward by the first single moving distance D _1. In the diagram shown in b of FIG18 , the second ordinate value of the list element corresponding to the contact “Jiang Er” becomes the value obtained by subtracting the first single moving distance D ₁ from the list height s, which is less than s. Therefore, the list element corresponding to the contact “Jiang Er” is moved from the invisible area to the visible list. As shown in b of FIG18 , the list element corresponding to the contact “Jiang Er” is displayed on the display screen. And the target list elements in other invisible areas are also moved upward by the first single moving distance D ₁ in turn.

It can be understood that the embodiment of the present application is explained by taking the first single movement distance _D1 being equal to the height of the first list element as an example. In the actual implementation process, the first single movement distance _D1 may also be less than or greater than the height of the first list element.

For example, when the first single movement distance _D1 is less than the height of the first list element, the second ordinate value of the list element corresponding to the contact "甲一" is _-D1 , which is less than 0 and has exceeded the visible range. However, the first ordinate value of the list element corresponding to the contact "甲一" is still greater than 0, so the list element corresponding to the contact "甲一" is still in the visible list.

Exemplarily, when the first single moving distance _D1 is greater than the height of the first list element, the second ordinate value of the list element corresponding to the contact "甲一" is _-D1 , which is less than 0. At the same time, because the first single moving distance _D1 is greater than the height of the first list element, the first ordinate value of the list element corresponding to the contact "甲一" is also less than 0, that is, the list element corresponding to the contact "甲一" has been moved out of the visible ordinate range, so the wearable device can remove the list element corresponding to the contact "甲一" from the memory.

Optionally, when the jump distance is segmented, the single movement distance can be made as small as possible, so that the first list element, each middle list element, and the second list element move a smaller distance each time, which can make the scrolling effect of the list smoother, thereby improving the user experience.

After the first single movement distance described above is completed, similarly, each intermediate list element in the memory of the wearable device and the ordinate of the second list element continue to be moved upward by the second single movement distance D ₂ . In the diagram shown in b of FIG18 , the second ordinate value of the list element corresponding to the first list element contact “甲二” is 0, assuming that the second single movement distance D ₂ is equal to the height of the list element corresponding to the contact “甲二”. Afterwards, the coordinate information of each intermediate list element and the second list element are all moved upward by the second single movement distance D ₂ , that is, the first ordinate value and the second ordinate value of each intermediate list element and the second list element are subtracted by the second single movement distance D ₂ , and the diagram shown in c of FIG18 is obtained.

At this time, the second ordinate value of the list element corresponding to the contact "甲二" is -D ₂ , which is less than 0, and because the current moving distance is D ₂ , it is the height of the list element corresponding to the contact "甲二". Therefore, the first ordinate value of the list element corresponding to the contact "甲二" is 0, that is, the list element corresponding to the contact "甲二" has been moved out of the visible ordinate range, so the wearable device removes the list element corresponding to the contact "甲二" from the memory. The list element corresponding to the contact "姜一" also moves up by D ₂ , and its second ordinate value becomes 0, that is, the list element corresponding to the contact "姜一" becomes the first list element in the visible list.

In the diagram shown in b of FIG18 , assuming that the second ordinate value of the list element corresponding to the index letter “S” is the list height s, after moving upward by the second single moving distance D ₂ , in the diagram shown in c of FIG18 , the second ordinate value of the list element corresponding to the index letter “S” is the value obtained by subtracting the second single moving distance D ₂ from the list height s, which is less than s. Therefore, the list element corresponding to the index letter “S” is moved from the invisible area to the visible list. As shown in c of FIG18 , the list element corresponding to the index letter “S” is displayed on the display screen. And. The middle list elements and the second list elements in other invisible areas are also moved upward by the second single moving distance D _{2 in turn.}

It is understandable that the second single moving distance _D2 may also be smaller or larger than the height of the list element corresponding to the contact "甲二". The implementation method is similar to that described above and will not be described in detail here.

Similarly, in the figure shown in c of FIG18, the remaining middle list elements in the memory of the wearable device and the second list element are continuously moved upward by the third single movement distance _D3 , the fourth single movement distance _D4 , ... until the mth single movement distance _Dm , the list element corresponding to the index letter "T", that is, the second list element, is moved to the visible list to become the last list element in the visible list, that is, displayed on the display screen, and the display screen displays the interface shown in d of FIG18. Wherein, m is less than n.

After that, the list can continue to slide upward. For example, for the coordinate system shown in FIG. 14, in the interface shown in FIG. 18d, when the first ordinate value corresponding to the lower edge of the list element corresponding to the index letter "T" is less than the list height, the next list element of the list element corresponding to the index letter "T" in the preset list is loaded into the memory of the wearable device, and as the list slides upward, the next list element of the list element corresponding to the index letter "T" in the preset list is also moved upward and displayed on the display screen. In the interface shown in FIG. 18e, the next list element of the list element corresponding to the index letter "T" in the preset list, that is, the list element corresponding to the contact "Tao Yi", is displayed at the bottom of the display screen, and its second ordinate value is the first ordinate value of the list element corresponding to the index letter "T", that is, the sum of the second ordinate value of the list element corresponding to the index letter "T" and the height of the list element; its first ordinate value can be greater than or equal to the list height.

Assuming that the height of the list element corresponding to the contact "Shen Yi" in the interface shown in d of FIG. 18 is equal to the single moving distance D _n-1 of the n-1th segment, then at this time, the second ordinate value of the list element corresponding to the contact "Shen Yi" is -D _n-1 , which is less than 0, and because the current moving distance is D _n-1 , it is the height of the list element corresponding to the contact "Shen Yi". Therefore, the first ordinate value of the list element corresponding to the contact "Shen Yi" is 0, that is, the list element corresponding to the contact "Shen Yi" has been moved out of the visible ordinate range, so the wearable device removes the list element corresponding to the contact "Shen Yi" from the memory. The list element corresponding to the contact "Shen San" also moves up D _n-1 , and its second ordinate value becomes 0, that is, the list element corresponding to the contact "Shen San" becomes the first list element in the visible list, and the display screen displays the interface shown in e of FIG. 18.

After that, the list can continue to slide upward. In the interface shown in e of Figure 18, when the first ordinate value corresponding to the lower edge of the list element corresponding to the contact "Tao Yi" is less than the list height, the next list element of the list element corresponding to the contact "Tao Yi" in the preset list is loaded into the memory of the wearable device, and as the list slides upward, the next list element of the list element corresponding to the contact "Tao Yi" in the preset list also moves upward and is displayed on the display screen. In the interface shown in f of Figure 18, the next list element of the list element corresponding to the contact "Tao Yi" in the preset list, that is, the list element corresponding to the contact "Tao Er", is displayed at the bottom of the display screen, and its second ordinate value is the first ordinate value of the list element corresponding to the contact "Tao Yi", that is, the sum of the second ordinate value of the list element corresponding to the contact "Tao Yi" and the height of the list element; its first ordinate value can be greater than or equal to the list height.

Assuming that the height of the list element corresponding to the contact "Tao Yi" in the interface shown in e of FIG. 18 is equal to the single moving distance D _n of the nth segment, then at this time, the second ordinate value of the list element corresponding to the contact "Tao Yi" is -D _n , which is less than 0, and because the current moving distance is D _n, which is the height of the list element corresponding to the contact "Tao Yi". Therefore, the first ordinate value of the list element corresponding to the contact "Tao Yi" is 0, that is, the list element corresponding to the contact "Tao Yi" has been moved out of the visible ordinate range, so the wearable device removes the list element corresponding to the contact "Tao Yi" from the memory. The list element corresponding to the index letter "T" also moves up by D _n , and its second ordinate value becomes 0, that is, the list element corresponding to the index letter "T" becomes the first list element in the visible list, and the display screen displays the interface shown in f of FIG. The jump from the first list element to the second list element with a scrolling effect is completed.

In the embodiment of the present application, the jump distance is divided into multiple sections to obtain multiple single-movement distances; according to the list jump direction, the coordinate information of each target list element is moved by the first single-movement distance to obtain the coordinate information of each target list element after the move; the visible vertical coordinate range corresponding to the display screen is obtained; the target list elements whose coordinate information after the move is within the visible vertical coordinate range are displayed on the display screen according to the coordinate information after the move, and the target list elements whose coordinate information after the move exceeds the visible vertical coordinate range are removed from the memory; the operation of moving the coordinate information of each target list element by the next single-movement distance according to the list jump direction, and displaying or removing the target list element according to the coordinate information after the move is repeatedly performed until the second list element is completely displayed on the display screen. In this way, the jump distance is divided into multiple single-movement distances, and the first list element, each intermediate list element, and the second list element are moved by the single-movement distance in sequence according to the list jump direction. When the single-movement distance is small, the movement of each list element can be made smoother.
