Background Art

With the rapid development of mobile Internet, users' demand for mobile applications is growing, and the way of presenting information has become more diverse. In mobile application development, list controls are an important way to display display objects such as pictures and videos, and the experience they bring to users is particularly important. When a large number of display objects need to be displayed in the list, when the user slides the list, loading may cause freezes and delays, giving the user an unsmooth experience.

In order to improve the user experience, preloading technology is usually used, that is, loading the display objects of the list in advance before the user actually needs it, to ensure that the content in the display list can be quickly loaded. The existing technology monitors the sliding event through a listener. When the sliding action is monitored, the corresponding callback method is used to implement preloading. However, the triggering mechanism of this method is very sensitive. During a sliding of the list, there may be multiple calls to the callback method. Even if the list is slid a few pixels, the callback method will be called for preloading. This frequent call situation has a great adverse effect on network performance and gives users a sense of loading lag.

DETAILED DESCRIPTION

The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be construed as being limited to the embodiments described herein. Instead, these embodiments are provided to provide a more thorough and complete understanding of the present application. It should be understood that the drawings and embodiments of the present application are only for exemplary purposes and are not intended to limit the scope of protection of the present application.

The term "including" and its variations used herein are open inclusions, i.e., "including but not limited to". The term "based on" means "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

In this specification, when directional terms such as "up", "down", "upward", and "downward" are mentioned, they are relative descriptions used for ease of understanding. These terms do not limit specific absolute directions, but are relative to the arrangement direction of objects in the list control. Here, the so-called "up" and "down" refer to the relative positions of the object list in the list control, where "up" refers to the starting end or top of the object list in the list control, and "down" refers to the end or bottom of the object list in the list control. It should be noted that the use of these directional terms is only for illustration, intended to help understand the movement and binding process of objects in the list control, and does not represent the actual physical direction or absolute position.

In the development of network applications, list controls are an important way to display display objects such as pictures and videos, and the experience they bring to users is particularly important. However, when the number of objects that need to be displayed in the list is large, loading a large number of display objects may cause freezes and delays when the user slides the list, which brings an unsmooth experience to the user. In order to improve the user experience, preloading technology is usually used, that is, loading the display objects of the list in advance before the user actually needs it, to ensure that the content in the display list can be loaded quickly. The prior art monitors sliding events through a listener, and when a sliding action is detected, the callback method corresponding to the sliding is called to achieve preloading. However, the triggering mechanism of this method is very sensitive. There may be multiple calls to the callback method in the process of sliding the list once. Even if the sliding amplitude is very small, it will trigger preloading, resulting in a waste of network resources and aggravated freezes and delays.

To this end, the present application provides a method, device, system and medium for preloading list display objects, which determines the sliding direction of the list by analyzing the previous and subsequent changes in the position of the target display object in the display window, and then selects the preloaded object accordingly. This method uses the change in the position of the display object as the trigger condition for starting preloading, ensuring that the objects that are about to appear in the display window are preloaded when necessary, effectively reducing the unnecessary consumption of network resources, preventing interface freezes and response delays caused by excessive preloading, ensuring the smoothness of the list during the sliding process, and significantly enhancing the user's interactive experience.

Exemplary Methods

Referring to FIG. 1 , FIG. 1 is a flow chart of a method for preloading a list display object provided by an embodiment of the present application, and the method specifically comprises the following steps:

Step 101: In response to a new complete target display object appearing in a display window of a terminal device, determine the i-th binding position of the object list corresponding to the display window according to the position of the target display object in the object list.

In the embodiment of the present application, the display object refers to an element in a list control that is used to display various information contents. The display object usually appears in scenarios such as news information applications, video playback applications, and picture browsing applications.

There are many types of display objects, including but not limited to the following:

Image: Displays static images, which can be a single image or a collection of images.

Video: Display dynamic video content, which can be short or long.

Animation: Displays dynamic images, such as GIFs or video frame sequences.

Text: Displays text information, such as title, description, tags, etc.

Others: such as audio files, live streams, etc.

There are rich types of display objects to meet users' diverse information needs. Users can click on a display object to view detailed information corresponding to the display object, such as viewing the full text of a news item, playing a video, viewing picture details, etc.

An object list refers to a collection of all display objects stored in an application and used to display in a list control. A display window refers to a screen area on a terminal device used to display a list control. An object list includes multiple display objects arranged in sequence, and a display window can display some of the display objects in the object list at a time.

When a complete target display object appears, the i-th binding position of the display window is determined according to the position of the target display object in the object list. This step is the updating process of the binding position, that is, each time a complete target display object appears in the display window, the i-th binding position is updated and the number i is updated at the same time.

Each display object corresponds to a view manager, which is a control for managing display objects. Binding is the process of associating the view manager corresponding to the display object with the display window. When a new complete display object appears during the sliding of the object list, the view manager corresponding to the target display object is bound to the display window to load the target display object into the display window.

In a possible implementation, the method provided in the embodiment of the present application for determining the i-th binding position of the object list corresponding to the display window according to the position of the target display object in the object list may specifically include:

During the sliding of the object list caused by the touch operation, the position of the target display object in the object list is determined as the i-th binding position of the object list corresponding to the display window.

The position of the target display object in the object list is determined as the i-th binding position of the object list corresponding to the display window. For example, when a user uses a mobile phone in portrait mode and generates a touch operation, slides the object list from the bottom to the top, and the target display object appears at the bottom of the display window, there are 5 binding events, and its sorting position in the object list is the 5th binding position. If the sliding continues in this direction, a new target display object will appear in the display window, and its position is the 6th binding position, and so on.

Specifically, in the list control RecyclerView, each display object corresponds to a view holder ViewHolder. When there is a picture corresponding to the ViewHolder that appears completely in the display window, it is bound to the display window. If the last binding event is the 10th binding, the position of the picture in the list is the 11th binding position.

By determining the position of the target display object in the object list as the latest binding position of the display window, accurate tracking of the binding event position caused by list sliding is achieved. The change of the binding position can reflect the trend of the list sliding direction, providing a basis for determining the subsequent list sliding direction.

Step 102: determining a list sliding direction of the object list in response to a touch operation according to the i-th binding position and the (i-1)-th binding position, where the touch operation is used to cause the target display object to appear in the display window.

When the user slides the list, the position of the target display object in the list will change. By comparing the i-th binding position of the current target display object with the i-1th binding position of the previous target display object, the direction trend of the display object change is analyzed to determine the sliding direction of the list. For example, when the user uses the mobile phone in portrait mode and generates a touch operation, sliding the object list from the bottom up, a new target display object will appear at the bottom of the screen based on the list sliding trend. The i-th binding position is at the bottom of the screen, and the i-1th binding position is above the i-th binding position. The changes in the binding positions before and after reflect the changes in the sliding direction of the list.

In a possible implementation, the method of determining a list sliding direction of the object list in response to a touch operation according to the i-th binding position and the i-1-th binding position provided in an embodiment of the present application may specifically include:

The direction from the i-th binding position along the list sliding axis to the i-1-th binding position is determined as the list sliding direction.

The list sliding axis refers to sliding in two directions along a certain linear axis during the list sliding process. For example, when a user uses a mobile phone to browse product information up and down, the vertical direction relative to the mobile phone screen is the list sliding axis.

Because what needs to be judged to determine the preloaded object is the direction of the list sliding, not just the direction from the i-th binding position to the i-1-th binding position. Therefore, the directions of the two binding positions should be converted into the directions of the corresponding list sliding axes to reflect the list sliding direction.

Specifically, when the user uses the mobile phone in portrait mode and slides the product list up and down, during the downward sliding process, the original 4th binding position is located at the top of the screen, and a new complete target product image appears at this time. The 5th binding position is located at the top of the screen, and the image of the 4th binding position appears below the 5th binding position as the list slides. The direction from the 5th binding position along the list sliding axis to the 4th binding position is determined as the list sliding direction from top to bottom.

According to the i-th binding position pointing to the i-1th direction along the list sliding axis, the change of the binding position is used to reflect the list sliding direction, so the list sliding direction can be inferred in time, providing directional guidance for defining the scope of preloaded objects. More importantly, the embodiment of the present application limits the frequency of monitoring the list sliding changes during the preloading process based on the newly appeared complete target object as a trigger signal, which means that only when a new target object is completely presented in the display window, will the sliding changes of the object list be recorded and responded to trigger the preloading process, thereby avoiding unnecessary preloading triggers and consuming network performance.

Step 103: According to the list sliding direction and the i-th binding position, determine the preload object after the touch operation from the object list, and preload the preload object.

According to the sliding direction of the list and the i-th binding position, the sliding direction of the list can be determined and the display objects that will appear can be predicted, and the objects that need to be preloaded can be determined accordingly. For example, if the user is sliding the list upward, the display objects below the i-th binding position can be preloaded. After the preload objects are determined, these objects will be preloaded. Preloading usually includes caching the data content of the preloaded objects locally, so that it has the ability to quickly load and display in the display window, so that the user cannot perceive the process of display object loading.

In a possible implementation, the method provided in the embodiment of the present application for determining the preloaded object after the touch operation from the object list according to the list sliding direction and the i-th binding position may specifically include:

N consecutive display objects in the direction opposite to the list sliding direction at the i-th binding position are determined as preloaded objects, where N is a preset integer.

After determining the list sliding direction and the current binding position, which display objects are specifically selected for preloading. The present invention proposes a simple preloading strategy, that is, starting from the current binding position, along the opposite direction of the list sliding direction, N display objects are continuously selected as preloading objects. Wherein N is a preset integer, which can be adjusted according to actual needs.

Suppose a user uses a shopping app and swipes up the list from the bottom of the screen. The currently displayed product image is the 20th item from top to bottom in the object list. According to the method of the embodiment of the present application, the binding position of the 20th product is determined, the sliding direction is determined to be upward based on the current binding position and the last binding position, and the preloaded object is determined based on the opposite direction of the sliding direction and the value of N. For example, if N is set to 5, the preloaded objects are the images of products from 21 to 25. When the user continues to swipe up, the 21st product will appear on the screen. At this time, the image of the 21st product has been preloaded and can be displayed immediately, avoiding the time for the user to wait for the image to load.

The preloaded object range is divided based on the sliding direction according to the list sliding direction and the preset integer N. By presetting N, it is ensured that the number of preloaded objects is limited and controllable, and there will not be a large number of preloading processes at the same time, resulting in excessive consumption of network performance.

In a possible implementation, the preloading of the preload object provided in the embodiment of the present application may specifically include:

The business data model of the preloading object is converted into a preloading model in turn, and a preloading task corresponding to the preloading model is established. When the preloading task is called, the display object corresponding to the preloading task is cached so that it has the ability to be directly displayed in the display window.

The business data model refers to the object that stores the preloaded object data, such as product information, news content, etc. The preload model refers to the data structure used for the preload operation. The preload task refers to the thread or process that performs the preload operation.

Specifically, a news list application uses a RecyclerView control to display a news list. When the user starts to slide the list upward from the bottom of the screen, the system determines the preload objects based on the sliding direction and N, and converts the business data models of these objects into preload models. For example, the preload model may contain an image URL (Uniform Resource Locator), create a corresponding preload task PreloadRequestRunnable and add it to the linear pool, and when the CPU (Central Processing Unit) calls the preload task, it sends the image URL in the preload model to the image loading library, such as Fresco, to cache the corresponding image to disk or memory. When the preload task is completed, the system will cache the loaded image to memory and local disk, so that it can be directly displayed in the display window.

When the user slides to a preloaded image, the system can directly obtain the image from the disk or memory, thereby improving the image display speed and ensuring a smooth experience for users sliding the list.

In a possible implementation, the method provided in the embodiment of the present application may further include:

Determine that a new complete target display object appearing in the display window is a preload cancellation object;

Determining that the display object being separated from the display window is a preload cancellation object;

When a display object is separated from the display window, N consecutive display objects at the i-th binding position in the sliding direction of the list are determined as canceled preload objects, where N is a preset integer;

The preloading tasks corresponding to the preloading cancellation objects are canceled in sequence.

In the process of executing the preloading task, there may be execution failures. These task processes or threads will always exist in the blocking queue of the linear pool. For the display window that is being displayed or the display object that has been displayed, it is necessary to check whether the corresponding preloading task still exists. For the determined canceled preloading object, its corresponding preloading task will be canceled. The process of canceling preloading is similar to the preloading process. The business data model of the canceled preloading object is converted into a preloading model in turn, and the linear pool is traversed. If there is a preloading task corresponding to the current converted preloading model, the preloading task will be canceled.

Immediately clean up unexecuted preload tasks to avoid consumption of process resources.
