Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. The terms used in the following embodiments are for the purpose of describing particular embodiments only, and are not intended to be limitations of the present application. As used in the specification of this application and the appended claims, the singular expressions "a," "an," "the," "above," "the," and "the" are intended to also Expressions such as "one or more" are included unless the context clearly dictates otherwise. It should also be understood that, in this embodiment of the present application, "one or more" refers to one, two or more; "and/or", which describes the association relationship of associated objects, indicates that there may be three kinds of relationships; for example, A and/or B can mean that A exists alone, A and B exist simultaneously, and B exists independently, wherein A and B can be singular or plural. The character "/" generally indicates that the associated objects are an "or" relationship.

In order to facilitate the understanding of the present application, the terms that may be involved in the present application are first explained.

A full-screen device refers to an electronic device that obtains a higher screen ratio by reducing the size of the frame. The screen ratio refers to the ratio of the screen area to the area of the front of the electronic device (generally the side where the screen is located is the front). By reducing the width of the bezel, the screen-to-body ratio of a full-screen device can reach about 80% to 90%.

The waterfall screen device is the product of further improvement on the basis of the full screen device. The side of the screen of the waterfall screen device has a certain arc, so compared with the full screen device, the waterfall screen device can completely cancel the borders on both sides of the screen, further improving the screen ratio, so that the screen ratio of the waterfall screen device can reach 90. %above.

Generally, the screen of the full-screen and waterfall screen devices can be provided with a punching area. The shape of the punching area can be a circle, a rectangle with rounded corners or other irregular shapes, and the punching area can be located at a corner of the screen (generally located at position close to the upper left corner), or it may be located at the top center of the screen, and the position and shape of the hole-digging area are not limited in this embodiment. Devices that need to be installed on the front of electronic equipment, such as front-facing cameras, proximity light sensors, etc., can be installed in the hole-drilling area. Therefore, the above-mentioned full screen and waterfall screen provided with a hole-digging area may be collectively referred to as a hole-digging screen, and an electronic device equipped with a hole-digging screen may be referred to as a hole-digging screen device.

The horizontal swipe gesture operation is a gesture commonly used in electronic devices to switch applications. The electronic device can switch between multiple previously run applications in response to the user's lateral swipe gesture operation.

When a user performs a horizontal swipe gesture operation, first touch the screen with a finger (or a stylus) and swipe horizontally on the screen. As the user swipes, the electronic device can sequentially display the cards of the applications that have been running in the recent period on the screen. , for example, after the electronic device is unlocked, the weather, navigation, video and chat applications have been run in sequence, then when the user touches the screen and swipes, the electronic device displays the cards corresponding to the chat, video, navigation and weather applications in sequence (displayed in the running order, The card of the last running application is displayed first), when the user stops swiping and lifts his finger (or stylus) from the screen, the electronic device switches to the application corresponding to the currently displayed card. For example, when the user lifts the finger, the electronic device displays the card of the video application, and the electronic device switches from the current interface to the interface of the video application.

For the convenience of description, the horizontal swipe gesture operation can be divided into a horizontal swipe touch gesture and a horizontal swipe up gesture. This includes the movement of the finger (or stylus) to stop sliding and lift off the screen.

In some embodiments, the display screen 194 can be combined with a touch sensor to form a touch screen, and the user can interact with the electronic device by clicking or swiping on the touch screen (with a finger or a stylus).

The above is a specific description of the embodiments of the present application by taking the electronic device 100 as an example. It should be understood that the structures illustrated in the embodiments of the present application do not constitute a specific limitation on the electronic device 100 . Electronic device 100 may have more or fewer components than shown in the figures, may combine two or more components, or may have different component configurations. The various components shown in the figures may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

The electronic equipment provided by the embodiments of the present application may be user equipment (UE), for example, may be a mobile terminal (such as a user mobile phone), a tablet computer, a desktop computer, a laptop computer, a handheld computer, a netbook, and a personal digital assistant (personal digital assistant, PDA) and other equipment.

In addition, an operating system runs on the above-mentioned components. For example, the iOS operating system developed by Apple, the Android open source operating system developed by Google, and the Windows operating system developed by Microsoft. Applications can be installed and run on this operating system.

The operating system of the electronic device 100 may adopt a layered architecture, an event-driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture.

For example, the above-mentioned electronic device can be installed to run a navigation application, a music application, a chat application, a game application, a video application, and the like.

When the screen of the electronic device is a hole-digging screen, the application interfaces of different applications adapt to the hole-digging screen differently.

The application interface of some applications is adapted to the hole-punch screen. The application interface of these applications can occupy the entire hole-punch screen. Therefore, when displaying the application interface of these applications, the electronic device does not need to display occlusion images in the top area and side area of the screen. .

The application interface of other applications is not suitable for the hole-digging screen. When the application interface that is not suitable for the hole-digging screen is displayed on the hole-digging screen, the application interface cannot occupy the entire screen. When the application interface of the hole screen is used, an occlusion image will be displayed in the top area and/or side area of the screen, so that the unobstructed visible area on the screen can be adapted to the application interface.

The occlusion image refers to an image displayed by the electronic device on the top area and/or the side area of the screen to occlude the corresponding area. The style and size of the occlusion image can be determined based on the default configuration of the system or based on user settings.

Taking FIG. 2 as an example, a schematic diagram of an electronic device displaying an application interface not adapted to the hole-digging screen and blocking images on a hole-digging screen provided by the present application. It can be seen that a hole-digging area 201 is provided on the screen of the electronic device 100 , and a front camera is installed in the hole-digging area 201 . The top of the screen, that is, the area where the punching area 201 is located is the top area 202 of the punching screen, and the strip-shaped areas on both sides of the screen are the side areas of the punching screen.

When the electronic device 100 starts and runs the chat application, the illustrated interface of the chat application is displayed on the hole-digging screen of the electronic device. Since the interface of the chatting application is not adapted to the hole-digging screen, while displaying the interface of the chatting application, the electronic device displays the top black bar 204 as shown in FIG. 2 in the top area 202 of the hole-digging screen. The area 203 displays the side black bars 205 shown in FIG. 2 , the top black bars 204 and the side black bars 205 shown in FIG. 2 , which is a specific implementation form of the occlusion image described in this application.

In addition to the scenario shown in Figure 2, in practical applications, when displaying an application interface that is not adapted to the hole-digging screen, the electronic device can display the top area and the side area at the same time according to the area covered by the application interface on the hole-digging screen. The occlusion image, or the occlusion image can be displayed only in the top area, and the occlusion image can be displayed only in the side area. In a word, the specific position where the occlusion image is displayed may be determined according to the currently displayed application interface, which is not limited in this embodiment.

It can be seen that when the electronic device switches from the application adapted to the punching screen to the application that is not adapted to the punching screen, the occlusion image is displayed on the screen. When the application of the hole-punch screen is used, the occlusion image displayed on the screen is hidden.

In the related art, when the electronic device displays or hides the occlusion image following the switching of different applications, there are the following problems:

When current electronic devices switch from one application to another, they adjust the display or hide of the occluded image on the screen after the application switching effect is played. Generally, after the application switching effect is played, the interface displayed on the screen jumps, from the interface displaying the occlusion image to the interface for hiding the occlusion image, or from the interface for hiding the occlusion image to the interface for displaying the occlusion image. This kind of jump after the application switching effect is played will cause a visual stutter, that is, the user feels that the electronic device has stuttering and screen splashes in the process of switching applications.

Further, since the current electronic device hides the occlusion image on the screen by default during the playback of the application switching effect, after the application switching effect is played, it is determined whether to add the occlusion image according to the adaptation of the switched application interface, resulting in During the application switching process, there are at most two jumps (splash screen) at least once.

In view of the above problems, the present application provides a display optimization method when switching applications, so as to improve the feeling of stuttering and flickering caused by switching applications of electronic devices, and improve the user experience.

The following takes a specific electronic device, a smart phone, as an example to describe a scenario in which the mobile phone switches applications to which the display optimization method of the present application is applied.

Please refer to FIG. 3 , which is an example of a scenario in which a mobile phone switches from an application adapted to the hole-digging screen to an application not adapted to the hole-digging screen provided by the present application.

When the mobile phone is in the vertical screen state, the user opens the video application installed on the mobile phone, the mobile phone starts to run the video application in response to the user operation, and displays the interface of the video application in the vertical screen mode as shown in (1) of Figure 3. The video application interface in portrait mode is adapted to the hole-digging screen. Therefore, when the video application interface in portrait mode is displayed, the occlusion image is not displayed on the hole-digging screen.

During the running of the video application, the user performs the horizontal swipe gesture operation as shown in (1) of Figure 3, and the mobile phone responds to the horizontal swipe gesture operation and switches from the video application to another application that was run most recently. Switch from video app to chat app.

When the mobile phone switches from one application to another, the preset application switching animation effect can be played, or the application switching animation effect can not be played. The specific form of the application switching animation effect can be the default setting of the system, or the user The specified form, this embodiment does not limit whether to play the application switching animation effect, and the specific form of the application switching animation effect.

Exemplarily, when the mobile phone switches from a video application to a chat application, the application switching animation effect shown in (2) of Figure 3 can be played, that is, the interface of the video application that has been cut off is gradually moved out of the screen to the right until The interface of the video application disappears, and at the same time, the interface of the entered chat application is moved into the screen from the left until the interface of the chat application is completely displayed on the screen.

Since the chat application interface in portrait mode is not adapted to the hole-punch screen, when the mobile phone displays the chat application interface in portrait mode, the occlusion image is displayed on the hole-punch screen, that is, the black top shown in (3) of Figure 3 is displayed. bar and side black bars.

Please refer to FIG. 4 , which is an example of a scenario in which a mobile phone switches from an application interface that is not adapted to the hole-digging screen to an application interface that is adapted to the hole-digging screen provided by the present application.

When the mobile phone is in the vertical screen state, the user opens the chat application installed on the mobile phone, the mobile phone starts to run the chat application in response to the user operation, and displays the interface of the chat application in the vertical screen mode as shown in (1) of FIG. 4 . The chat application interface in portrait mode is not adapted to the hole-punch screen, so when the chat application interface in portrait mode is displayed, the mobile phone displays an occluded image on the hole-punch screen, that is, the top black bars and side bars shown in (1) of Figure 4. Side black bars.

During the running of the chat application, the user performs a horizontal swipe gesture as shown in (1) of Figure 4, and the mobile phone responds to this action and switches from the chat application to another application that was run most recently, in this example, from the chat application. Switch to the video app.

Exemplarily, when the mobile phone is switched from a chat application to a video application, the application switching animation effect shown in (2) of FIG. The interface of the chat application disappears, and at the same time, the interface of the video application is moved to the screen from the left until the user releases the hand. After the horizontal swipe gesture ends, the interface of the video application is completely displayed on the screen.

Since the video application interface in portrait mode is adapted to the hole-punch screen, when the mobile phone displays the video application interface in portrait mode, the occluded image on the hole-punch screen is hidden, that is, the top black bar shown in (1) of Figure 4 is hidden. and side black bars.

Please refer to FIG. 5 , which is an example of a scenario in which a mobile phone switches from an application interface that is not adapted to the hole-digging screen to an application interface that is not adapted to the hole-digging screen provided by the present application.

When the mobile phone is in the vertical screen state, the user opens the chat application installed on the mobile phone, the mobile phone starts to run the chat application in response to the user operation, and displays the interface of the chat application in the vertical screen mode as shown in (1) of FIG. 5 . The chat application interface in portrait mode is not adapted to the hole-punch screen, so when the chat application interface in portrait mode is displayed, the mobile phone displays an occluded image on the hole-punch screen, that is, the black bars at the top and the sides shown in (1) of Figure 5. Side black bars.

During the running of the chat application, the user performs a horizontal swipe gesture as shown in (1) of Figure 5, and the mobile phone responds to this action and switches from the chat application to another application that was run most recently, in this example, from the chat application. Switch to shopping app.

Exemplarily, when the mobile phone is switched from a chat application to a shopping application, the application switching animation effect shown in (2) of FIG. The interface of the chat application disappears, and at the same time, the interface of the entered shopping application is moved into the screen from the left until the user releases the hand. After the horizontal swipe gesture ends, the interface of the shopping application is completely displayed on the screen.

Since the shopping application interface in portrait mode is not adapted to the hole-punch screen, when the mobile phone displays the shopping application interface in portrait mode, the occluded image on the hole-punch screen is still displayed, that is, the top shown in (1) of Figure 5 is displayed. Black bars and side black bars.

It can be seen from (2) in Figure 5 that during the process of switching from the chat application to the shopping application, the mobile phone continues to display the top black bar and the side black bar before the user lets go, and the complete shopping application is displayed on the screen when the user lets go. After the interface is displayed, because the interface of the shopping application is not adapted to the punch-hole screen, the mobile phone continues to display the top black bar and the side black bar. That is to say, when the mobile phone switches between two application interfaces that are not adapted to the hole-digging screen, applying this solution can avoid blocking the image (that is, the aforementioned top black bars and side black bars) disappearing before the user lets go and then reappearing on the screen. Appears after the user lets go, preventing freezes and screen splashes when switching applications.

In this application, as an example, the horizontal swipe gesture operation is used as the operation of switching recent applications by default, that is, when the electronic device detects that the user performs the horizontal swipe gesture operation, the electronic device determines that the user's intention is to switch Recently applied. Switching the most recent application means that the electronic device switches from the currently running application to another application that has been run most recently. For example, the electronic device runs the A application for a period of time, and then runs the B application. During the running of the B application, the user performs a horizontal swipe Gesture operation, the electronic device switches back to the A application.

In some optional embodiments, in addition to the above-mentioned horizontal swipe gesture operation, the electronic device can also be configured to switch recent applications in response to other actions of the user, such as clicking a virtual button on the screen, or other gesture operations. The example does not limit the specific form of the operation of switching the most recent application.

In order to more clearly illustrate the display optimization method of the hole-digging screen provided by the embodiments of the present application, the following uses the Android system with a layered architecture as an example to illustrate the technical architecture of the electronic device 100 as an example.

Please refer to FIG. 6 , which is a schematic diagram of the technical structure of the electronic device 100 provided in the present application.

The electronic device may include a hardware layer and a software layer, wherein the Android system of the layered architecture may include an application layer, an application framework layer, and a kernel layer. In some optional embodiments, the system of the electronic device may further include layers not mentioned in the above-mentioned technical architecture, such as an Android runtime (Android Runtime) and a system library.

The application layer can include a series of application packages, such as navigation applications, music applications and video applications. As shown in Figure 3, the application package can include video, chat, desktop (launcher), system user interface (SystemUI).

Applications such as navigation, chat, music and video are used to provide corresponding services to users. For example, users use video apps to watch videos and chat apps to chat with other users.

The desktop is used to display the application icons of some or all of the applications installed on the electronic device. The user can click the application icon to open the corresponding application. For example, the desktop displays the application icon of the video application, and the user can click the icon of the video application to open the video application.

The SystemUI is used to manage the user interface (User Interface, UI) of the electronic device. In this application, the SystemUI is used to manage the display and hiding of the occlusion images in the edge area of the hole-digging screen.

The application framework layer provides an application programming interface (application programming interface, API) and a programming framework for the applications of the application layer. The application framework layer includes some predefined functions. As shown in Figure 3, the application framework layer may include a window management service module (Window Manage Service, WMS), an input management module (also called Input), an application management service module (Application Manage Service, AMS), and the like.

WMS is used to manage window programs. The window manager can get the screen size, determine whether there is a status bar, lock the screen, take screenshots, etc. In this application, the WMS can create and manage windows corresponding to applications.

AMS is used to launch a specific application according to the user's operation. For example, when a user clicks a video application icon on the desktop, the AMS sets the video application to the foreground running state, and creates an application stack corresponding to the video application, so that the video application can run normally.

In the embodiment of the present application, the WMS includes a task record stack. The task record stack can record the applications that have been run by the electronic device for a period of time and their sequence, and the task record stack can be used to determine which application was run most recently.

As an example, after the user unlocks the electronic device, opens the navigation application, opens the video application after a period of time, opens the chat application after a period of time, and then returns to the system desktop from the chat application, in the task record stack, press the navigation application → video application → chat The sequence of applications records the above applications. When the user performs a horizontal swipe gesture operation, the electronic device can determine a previously running application in the task record stack according to the user's gesture and switch to the application. For example, in the above example, if the user switches to the most recently run application through the horizontal swipe gesture operation, the electronic device opens the chat application, and if the user switches to the penultimately run application through the horizontal swipe gesture operation, the electronic device Open the Video app.

When you need to determine the most recently run application, you can directly search for the latest recorded application from the task record stack.

The kernel layer is the layer between hardware and software. In this application, the core layer at least includes a touch driving module and a display driving module.

The display driving module is used to display a corresponding image on the touch screen according to the image data provided by the module of the application framework layer and the application program of the application layer. For example, a video application transmits a frame of image data of the video to the display driving module, and the display driving module displays a frame of image in the video on the touch screen according to the image data. The SystemUI transmits the image data of the occlusion image to the display driver module, and the display driver module displays the occlusion image in the area designated by the hole-digging screen according to the image data of the occlusion image.

The touch drive module is used to monitor the capacitance value of each area of the touch screen. When the user clicks or slides on the touch screen, the capacitance value of the clicked or swiped area will change. The touch drive module can monitor the change of the capacitance value of each area on the touch screen, and send a capacitance value change message to the input management module. The capacitance value change message carries information such as the change range of the capacitance value (or the capacitance sample value) of each area of the touch screen and the time of the change.

The input management module can determine the touch operation according to the reported capacitance value change message, and then send the identified touch operation to other modules. The touch operations here may include click operations, drag operations, and specific gesture operations (such as slide up gesture operations, horizontal slide gesture operations, etc.).

For example, in (1) of Figure 3, after the user swipes from the left side of the screen to the right, the input management module recognizes the swipe gesture according to the reported capacitance value change message, and then reports the swipe gesture to the desktop, thereby triggering the electronic device Execute the instruction to switch recent apps.

It should be noted that although the embodiments of the present application are described by taking the Android system as an example, the basic principles thereof are also applicable to electronic devices based on operating systems such as iOS or Windows.

The above technical architecture enumerates the modules and devices in the electronic device that may be involved in the present application. In practical applications, the electronic device may include all or part of the modules and devices of the above-mentioned technical framework, as well as other modules and devices not mentioned in the above-mentioned technical framework. Of course, it may also only include the modules and devices of the above-mentioned technical framework. This embodiment This is not limited.

The specific implementation of the display optimization method during application switching provided by the embodiment of the present application will be described below with reference to the technical architecture of the electronic device shown in FIG. 6 .

Please refer to FIG. 7 , which is a sequence diagram of a display optimization method when an application is switched according to an embodiment of the present application.

A01, start the first application.

The application management service module (hereinafter referred to as AMS), in response to the user operation, executes step A01 to start the first application.

The first application may be any application installed on the electronic device. In conjunction with the foregoing examples, the first application may be a chat application.

When using the electronic device, the user can open an application installed on the electronic device in various ways, for example, click the application icon on the desktop, click the notification message of the application in the message notification bar, and so on.

Taking the application icon on the desktop as an example, after the user clicks an application icon, the input management module identifies the user's click operation, and then reports the click operation to the desktop. The desktop determines the clicked application icon according to the user's click operation, and then according to the click operation The clicked application icon finds the application identifier of the corresponding application, and then sends the application identifier to the AMS, so that the AMS starts the clicked application.

As before, in step A01 , the AMS may specifically switch the application corresponding to the clicked application icon to run in the foreground, and create an application stack corresponding to the application.

Taking the chat application as an example, the user clicks the icon of the chat application on the desktop, the desktop recognizes that the icon of the chat application is clicked according to the reported click operation, and then sends the application identifier (such as the application name) of the chat application to the AMS. , perform step A01, switch the chat application to run in the foreground, and create an application stack of the chat application.

A02, notification startup window.

After the AMS starts the first application, step A02 is executed to the window management service module (hereinafter referred to as WMS), thereby triggering the WMS to create a window.

In A02, the AMS may send a window startup notification to the WMS, where the notification carries the application identifier of the first application started by the AMS. After the WMS receives the notification, it can create a window corresponding to the activated first application according to the carried application identifier.

A03, informing the system that the user interface displays the occlusion image.

In step A03, the WMS may first query the occlusion image display strategy of the first application, and then determine that the occlusion image needs to be displayed on the screen when displaying the interface of the first application according to the occlusion image display strategy of the first application. Therefore, the WMS reports to the system user interface Send a message to notify the system user interface to display an occlusion image.

After the window corresponding to the first application is activated, switch to the first application running in the foreground to send the image data of the application interface to the display driver module, and the display driver module can display the application of the activated application on the touch screen according to the image data of the application interface. interface.

The WMS records the occlusion image display strategy of each application installed on the electronic device, and the occlusion image display strategy of each application corresponds to the application identifier of the application. The application's occlusion image display strategy is used to indicate whether the application's interface is suitable for the hole-digging screen of the electronic device. By executing A03 to query the application's occlusion image display strategy, the WMS can determine whether the hole-digging screen needs to be displayed when the application interface is displayed. The top area and side area of show occlusion images.

Among them, for an application that supports landscape mode and portrait mode, the interface of the application in landscape mode and the interface in portrait mode are often different, so the occlusion image display strategy of the application can also include the landscape mode of the application. Whether the interface is suitable for the hole-digging screen, and whether the interface of the application in portrait mode is suitable for the hole-digging screen.

For applications that support landscape mode and portrait mode, in step A03, the WMS can determine whether the interface after the application is started is the interface in landscape mode or the interface in portrait mode according to whether the electronic device is currently in landscape or portrait state. , so as to query the corresponding occlusion image display strategies in different modes of the application.

If the application interface displayed after the application is started is not adapted to the hole-digging screen, a blocking image will be displayed in the top area and/or side area of the hole-digging screen when the application interface is displayed; if the application interface displayed after the application is started is adapted to the hole-digging screen Hole screen, hide the occlusion image on the hole screen when the application interface is displayed.

In some optional embodiments, for the application interface that is not adapted to the hole-digging screen, the applied occlusion image display strategy may specifically indicate the area where the occlusion image needs to be displayed, and the WMS controls the occlusion image display and display of the corresponding position according to the occlusion image display strategy. hide.

For example, for a waterfall screen, an application's occlusion image display policy can indicate that the application's interface in landscape mode is not adapted to the hole-punch screen, and indicate that the occlusion image needs to be displayed in the top area. When the application starts in landscape mode, WMS By querying the application's occlusion image display strategy, it is determined to display the occlusion image on the top and hide the occlusion image on the side.

Continuing the foregoing example, the first application may be a chat application, and in step A03, the WMS may query the occlusion image display policy of the chat application.

The occlusion image display strategy of the chat application may be that the interface of the chat application in the vertical screen mode is not adapted to the punch-hole screen, and when the interface of the chat application in the vertical screen mode is displayed, the occlusion image needs to be displayed in the top area and side area of the screen.

After receiving the notification to start the window of the chat application, the WMS determines that the chat application is opened in the portrait mode according to the current state of the electronic device, and then determines when the interface of the chat application in the portrait mode is displayed based on the above-mentioned chat blocking image display strategy. The black bars shown in (3) of Figure 3 need to be displayed in the top area and side area of the screen.

The applied occlusion image display strategy may be determined in various manners, and the specific determination manner is not limited in this embodiment.

As an example, the WMS may determine the applied occlusion image display policy as follows:

After the application is installed, the WMS can obtain the adaptation of the interface of the application to the hole-digging screen through the interface of the application. Each interface of the application has its corresponding task (Activity) object. After the application is installed, WMS can obtain the information of each activity of the application through the application interface, that is, the task information (ActivityInform). The task information contains the interface corresponding to the activity. The adaptation of the hole-digging screen, that is, whether the interface corresponding to each Activity is suitable for the hole-digging screen.

For the application interface that is not adapted to the hole-digging screen, WMS can determine the area where the occluded image needs to be displayed based on the default configuration information of the system. Exemplarily, the configuration information may be that a black border needs to be displayed in the top area when displaying an application interface that is not adapted to the hole-punch screen, or that it needs to be displayed in the top area and side when displaying an application interface that is not adapted to the punch-hole screen. The area displays black borders, or it is necessary to display black borders in the side area when displaying the application interface that is not adapted to the hole-digging screen.

In summary, the WMS can determine the application's occlusion image display strategy according to the adaptation of the interface corresponding to the Activity in the application's task information and the above-mentioned default configuration information.

A04, the occlusion image is displayed.

In response to the notification of the WMS in A03, the system user interface performs step A04 to display the occlusion image.

In step A04, the system user interface may send the occlusion image data of the WMS designated area to the display driver module of the kernel layer, and the display driver module displays the occlusion image in the corresponding area according to the occlusion image data.

Continuing the previous example, after WMS determines that it needs to display black bars in the top area and side area of the screen when the interface of the chat application is displayed in portrait mode, WMS sends a notification to the system user interface to display the top black bars and side black bars, and the system In response to the notification, the user interface sends the image data of the top black bars and the side black bars to the display driver module, and the display driver module displays the image data on the screen according to the image data of the top black bars and the side black bars as shown in Figure 4 (1) Top black bars and side black bars shown.

A05, report the horizontal swipe touch gesture.

During the running of the application, the touch driving module may report a message to the input management module, and the input management module identifies the touch operation performed by the user according to the reported message, and then reports the identified touch operation to the desktop.

When the user taps the screen with a finger (or a stylus) and starts to slide, the input management module detects the user's horizontal sliding touch gesture operation, executes step A05, and reports the horizontal sliding touch gesture to the desktop.

The input management module may be configured with an identifier used to represent each touch operation. The specific implementation of A05 may be that when the input management module recognizes that the user has performed a horizontal sliding touch gesture operation, the input management module sends a message to the desktop, The message carries an identifier representing the horizontal sliding touch gesture, and the horizontal sliding touch gesture can be reported to the desktop by inputting the management module in this way.

A06, query the occlusion image display strategy of the application that may be switched.

The implementation of step A06 may be that the desktop determines the applications that may be switched according to the user's horizontal swipe touch gesture, and then the WMS queries the occlusion image display policy of the applications that may be switched according to the identification.

It should be noted that A06 can be executed in real time before the horizontal swipe gesture operation ends, that is, before the input management module reports the horizontal swipe up gesture. That is to say, during the duration of the horizontal swipe touch gesture, the applications that may be switched will change with the user's swipe, and the desktop can determine the latest possible switched applications according to the user's horizontal swipe gesture in real time, so as to change the The corresponding identifier is sent to the WMS, so that the WMS can query the latest occlusion image display policy of the application that may be displayed in real time.

In A06, the desktop can specifically determine the applications that may be switched according to information such as the sliding direction and sliding distance of the user's horizontal sliding touch gesture, and the information such as the sliding direction and sliding distance can be reported to the desktop by the input management module.

Exemplarily, if the sliding direction is swiping to the right, the desktop may determine the previous application as an application that may be switched, and if the sliding direction is sliding to the left, the desktop may determine the latter application as an application that may be switched. The former application refers to the application recorded in the task record stack that has run before the currently running first application, and the latter application refers to the application recorded in the task record stack that has run after the currently running first application application. For example, it is recorded in the task record stack that the electronic device has successively run a navigation application, a video application, and a chat application. For a video application, the former application is the navigation application, and the latter application is the chat application.

Continuing the above example, if the user performs a horizontal swipe gesture while the electronic device is running the chat application, and the sliding direction is rightward, then it is determined that the application that may be switched is a video application, and it is assumed that after switching to a video application, the user performs a horizontal swipe Touch the gesture, and the swipe direction is swipe to the left, then it is determined that the application that may be switched is the next application in the task record stack, that is, the chat application.

A07, report the horizontal swipe raise gesture.

When the user stops sliding on the screen and lifts up the finger (or stylus) that taps the screen, the input management module detects the user's swipe-up gesture, executes step A07, and reports the swipe-up gesture to the desktop. For the specific implementation of A07, refer to A05, that is, the input management module can send a message to the desktop, the message carries an identifier representing the horizontal slide up gesture, thereby completing the reporting of the horizontal slide up gesture.

A08, notify the application management service to start the second application.

In this embodiment, the second application refers to an application that needs to be switched after the user performs the horizontal swipe gesture operation. With reference to the example of FIG. 4 , during the operation of the chat application on the electronic device, the user performs a horizontal swipe gesture operation to switch to the video application. In this scenario, the chat application is the aforementioned first application, and the video application is the second application.

In A08, the desktop may first determine which application the second application is, and then send the corresponding application identifier to the AMS, so that the AMS starts the second application. For example, if the desktop determines that the video application is the second application, the desktop sends the application identifier of the video application to the AMS in A08, so that the AMS starts the video application.

In some optional embodiments, the desktop may determine the newly determined application that may be switched before the input management module reports the horizontal swipe raise gesture as the second application.

For example, the newly determined application that may be switched before the input management module reports the horizontal slide up gesture is a video application, and after the input management module reports the horizontal slide lift gesture, the desktop can determine that the video application is the second application.

A09, notify the window for launching the second application.

After receiving the notification from the desktop, the AMS executes step A09, so as to notify the WMS of the window message that the second application needs to be started. In A09, the AMS may specifically send the application identifier of the second application to the WMS, and may also send messages other than the application identifier of the second application, which is not limited in this embodiment.

Continuing the foregoing example, after receiving the application startup notification carrying the application identifier of the video application, the AMS executes A09 to forward the application identifier of the video application to the WMS.

In some optional embodiments, the desktop may also directly notify the WMS to start the window of the second application.

The following describes the implementation process of steps A05 to A09 in conjunction with the example of FIG. 4 :

During the running of the chat application on the electronic device, the user performs a horizontal swipe touch gesture of sliding to the right, and the input management module executes A05 after detecting the horizontal swipe touch gesture, and reports the horizontal swipe touch gesture to the desktop, and also reports the sliding direction.

Among them, the desktop responds to the horizontal swipe touch gesture, and displays the dynamic effect of the card of the application that has been running in the recent period of time. That is to say, after the input management module reports the horizontal swipe touch gesture, the desktop can follow the user's sliding in order. Cards showing apps that have been running in the most recent period of time.

In A06, the desktop determines that the application that may be switched is the previous application according to the horizontal sliding touch gesture and its sliding direction, so the desktop notifies the WMS to query the occlusion image display strategy of the previous application, and the WMS knows that the previous application is a video according to the task record stack. application, so the WMS queries the occlusion image display strategy of the video application.

When the screen of the electronic device displays the card corresponding to the video application, the user stops sliding and lifts the finger touching the screen. After the input management module detects the action, it executes A07 and reports the horizontal slide up gesture to the desktop.

When the input management module reports the horizontal swipe up gesture, the application that may be switched is still the video application, so the intention corresponding to the horizontal swipe gesture of the desktop user is to switch to the video application, that is, the video application is determined as the second application, and then the desktop executes Step A08: Send the application identifier of the video application to the AMS, so as to notify the AMS to start the video application.

After receiving the notification, the AMS forwards the application identifier of the video application to the WMS, so as to trigger the WMS to start the window of the video application.

A10. Obtain the occlusion image display strategy of the second application.

After the WMS receives the notification to start the second application window, on the one hand, it can start the corresponding window, and on the other hand, it can execute step A10 to obtain the occlusion image display policy of the second application.

In step A06, each time the WMS queries the occlusion image display policy of the potentially switchable application, it can cache the queried occlusion image display policy, and the second application is the newly determined possible switch application before reporting the horizontal swipe raise gesture. It can be understood that, in this case, the occlusion image display strategy newly queried and cached by the WMS before the input management module reports the horizontal swipe raise gesture is the occlusion image display strategy of the second application in step A10.

Therefore, when executing A10, the WMS can directly read the occlusion image display policy of the second application cached when executing A06.

The advantage of querying and caching the occlusion image display strategy of the second application in advance in A06 is that when step A10 is executed, it can be quickly determined whether to hide or display the occlusion image according to the cached occlusion image display strategy, so that the system user interface can start as soon as possible Hide the occlusion image to further shorten the time difference between hiding the occlusion image and the end of the application interface switching.

According to the occlusion image display strategy of the second application, the WMS can determine whether the second application to be launched is adapted to the hole-digging screen, and then determine whether the occlusion image needs to be displayed on the hole-digging screen or the hole-digging screen needs to be displayed when the interface of the second application is displayed. Hidden occlusion images on the aperture screen.

Similar to A03, if the second application corresponds to two occlusion image display strategies in landscape mode and portrait mode, in A10, WMS can determine whether the current state of the electronic device is landscape or portrait, and then obtain the corresponding occlusion image. Show strategy.

Continuing the previous example, the occlusion image display strategy of the video application may be that the interface of the video application in the portrait mode is adapted to the hole-punch screen, and the interface of the video application in the landscape mode is not adapted to the hole-punch screen. After receiving the application identifier of the video application sent by the AMS, the WMS determines that the electronic device is currently in a vertical screen state, and searches and obtains the occlusion image display strategy of the vertical screen mode of the video application according to the application identifier of the video application. Since the occlusion image display strategy indicates that the interface of the video application in portrait mode is adapted to the hole-punch screen, WMS can determine through A10 that the occlusion image on the hole-punch screen needs to be hidden when displaying the interface of the video application.

A11, Notify the system user interface to hide the occlusion image.

After the WMS determines that the occlusion image needs to be hidden when displaying the interface of the second application, A11 is executed, and a notification of hiding the occlusion image is sent to the system user interface, so as to trigger the system user interface to hide the occlusion image.

Continuing the previous example, after WMS determines that the occlusion image needs to be hidden when displaying the interface of the video application, it executes A11 to send a notification of hiding the occlusion image to the system user interface, so as to trigger the system user interface to display the interface of the chat application. Top black bars and side black bars are hidden.

A12, hide the occlusion image.

After receiving the notification from WMS, the system user interface executes A12 to hide the occlusion image displayed on the hole-digging screen when the interface of the first application is displayed. Taking Figure 4 as an example, in A12, the system user interface can hide the occlusion image displayed on the hole-digging screen. Top black bars and side black bars are hidden.

In step A12, the system user interface may use various methods to hide the occlusion image on the screen when the interface of the first application is displayed, and the specific method is not limited in this embodiment.

In some optional embodiments, the system user interface may immediately hide all the occlusion images displayed on the screen after receiving the notification from the WMS.

In some optional embodiments, the system user interface can also reduce the size of the occlusion image displayed on the screen successively after receiving the notification from the WMS, that is, after receiving the notification from the WMS, the occlusion image is reduced at regular intervals size until the occluded image disappears completely.

In some optional embodiments, the system user interface may further increase the transparency of the occlusion image displayed on the screen one by one after receiving the notification from the WMS, that is, after receiving the notification from the WMS, the occlusion image is reduced at regular intervals size until the occluded image is completely transparent.

By gradually reducing the size and gradually increasing the transparency, the occlusion image is hidden, which can avoid the abruptness caused by the sudden disappearance of the occlusion image, and improve the user's visual experience.

A13, start the second application.

For a specific startup process of the second application in step A13, reference may be made to step A01.

It should be noted that step A13 may be performed simultaneously with step A10, or may be performed after step A10 is performed, or may be performed before step A10, as long as step A10 is ensured to be performed before step A15. The execution order is not limited. That is, the AMS may first send the application identifier of the second application to the WMS, and then start the second application, or may send the application identifier of the second application to the WMS in the notification of starting the second application.

For the specific implementation of A13, refer to step A01, which will not be repeated.

A14, play the application switching animation effect.

In step A14, the WMS may play any form of application switching animation effect according to the user configuration or the default setting of the system, which is not limited in this embodiment.

Exemplarily, the application switching animation effect played by the WMS in A14 may be as shown in FIG. 4 .

The specific implementation of step A14 may be that the WMS controls the desktop playback application to switch the animation effect by calling a specific function.

This embodiment has the following beneficial effects:

Before playing the application switching animation effect, the desktop notifies the WMS to query the occlusion image display policy of the second application in advance, so that the WMS can notify the system user interface in advance to hide the occlusion image. Therefore, in this embodiment, when the electronic device switches from the currently running application When it comes to the last application that runs recently, the occlusion image can be hidden before the application switching animation effect is played, which shortens the time difference between hiding the occlusion image and the end of the application interface switching, and alleviates the problem caused by hiding the occlusion image when switching applications. Visual lag improves user experience.

Further, after the desktop determines the second application to be switched, the system user interface starts to hide the occlusion image, and does not hide the occlusion image until the desktop receives the reported horizontal swipe up gesture, which avoids switching from the first application to During the second application period, the occlusion image frequently changes, that is, it appears and disappears repeatedly, which alleviates the visual effect of interface jitter caused by the occlusion image repeatedly appearing and disappearing when the electronic device switches applications.

It should be noted that, in the embodiment shown in FIG. 7 , the first application is not adapted to the hole-digging screen, and the second application is adapted to the hole-digging screen as an example, which illustrates that the electronic device switches from the first application to the second application in response to the horizontal swipe gesture operation. 2. The method of hiding the occlusion image when applied. It can be understood that this method can also be applied to the process of switching the electronic device from the first application adapted to the punching screen to the second application not adapted to the punching screen.

Exemplarily, in the embodiment shown in FIG. 7, step A03 is modified to notify the system user interface to hide the occlusion image, step A04 is modified to hide the occlusion image, step A11 is modified to notify the system user interface to display the occlusion image, step A12 Modified to display the occlusion image, the process of switching the electronic device from the first application adapted to the punching screen to the second application not adapted to the punching screen can be obtained, and from the first application adapted to the punching screen to the non-adapted application For other steps in the second application switching process of the hole-digging screen, reference may be made to the embodiment shown in FIG. 7 , and details are not repeated here.

When switching from the first application adapted to the hole-digging screen to the second application that is not adapted to the hole-digging screen, the system user interface may display the occlusion image in various manners, and the specific manner is not limited in this embodiment.

In some optional embodiments, the system user interface may display the occlusion image on the hole-digging screen immediately after receiving the notification from the WMS. With reference to the example in Figure 3, the system user interface can display top black bars and side black bars in the top area and side area of the hole-digging screen immediately after receiving the notification from the WMS.

In some optional embodiments, after receiving the notification from the WMS, the system user interface may also display the occlusion image with the size gradually increasing in the designated area until the occlusion image is completely displayed, that is, until the size of the occlusion image reaches the set size. Value.

Combined with the example in Figure 3, after receiving the notification from WMS, the system user interface can display narrower top black bars and side black bars in the top area and side area of the hole-digging screen, and then increase the top black bars and side black bars successively. The width of the side black bars until the widths of the top black bars and the side black bars reach the set value, so that the top black bars and the side black bars achieve a visual fading effect.

In some optional embodiments, after receiving the notification from the WMS, the system user interface may further display an occlusion image whose transparency gradually decreases in a designated area until the occlusion image is completely opaque, that is, until the transparency of the occlusion image is reduced to 0% .

Combined with the example in Figure 3, after receiving the notification from the WMS, the system user interface can first display the top and side black bars with high transparency in the top area and side area of the hole-digging screen, such as displaying 80% transparency. The top black bar and the side black bar, then reduce the transparency of the top black bar and the side black bar successively, until the transparency of the top black bar and the side black bar reaches 0%, that is, it is completely opaque, making the top black bar and the side black bar black. The bar achieves a visual fade-in effect.

The occlusion image is displayed by gradually increasing the size and gradually reducing the transparency, which can avoid the sudden appearance of the occlusion image and improve the user's visual experience.

Generally, the interaction between various modules in the electronic device and the realization of the functions of the modules themselves all depend on the calling of various functions in the system. In order to further understand the display optimization method provided by this application, the following is an example in which the electronic device shown in FIG. The function call relationship inside the device.

Please refer to FIG. 8 , which is a signaling diagram of a display optimization method when an application is switched according to an embodiment of the present application.

As shown in Figure 8, the WMS can specifically include the following components:

The first task management component, also known as ActivityTaskManagerService; the interface information record component, also known as ActivityRecord; the display content component, also known as DisplayContent; the remote animation component, also known as RemoteAnimation, the second task management component, also known as HwActivityTaskManagerServiceEx, the phone window management component, Also known as HwPhoneWindowManager.

When the user touches the screen, the input management module calls 1. The touch event, also known as onTouchEvent(), processes the event triggered by the user touching the screen, thereby recognizing that the operation performed by the user is a swipe touch gesture, and then the input management module calls 2 , the touch gesture recognition function, also known as detectGesture_Down(), reports the horizontal sliding touch gesture to the desktop.

The process of calling 1 and 2 can be regarded as a specific implementation of step A05 in FIG. 7 .

After the desktop receives the reported swipe touch gesture, it determines that the user's intention is to display the recent task, and then calls 3 to start the recent task function, also known as startRecentActivity(). The first task management component of WMS, and then the first task management component calls 4, the visualization function, also known as makevisible(). By calling the visualization function, the first task management component sets the application recorded in the interface information recording component to be visualized, Thus, the electronic device can display the application recorded in the interface information recording component on the screen as the user slides.

After the desktop calls function 3, it also calls 5 to notify the desktop behavior function, also known as notifyLauncherAction(). As mentioned above, during the user's horizontal sliding touch gesture, the desktop determines that the user's intention is to switch based on information such as the sliding direction and sliding distance. To the previous application or the next application, that is, it is determined whether the application that may be switched in step A06 is the previous application or the latter application. And by calling the notification desktop behavior function, the desktop can notify the first task management component of the information of switching to the previous application or the next application.

The first task management component finds the application identifier of the previous application or the next application in the task record stack according to the information provided by the desktop, and then sends the application identifier to the second task management component. After receiving the application identifier of the application that may be switched, the second task management component calls 6 to query the top status function, also known as queryCutoutStatus(), which can query the occlusion image display strategy of the application that may be switched.

Exemplarily, the desktop determines that the application that may be switched is the previous application according to the sliding direction of the horizontal sliding touch gesture, and then calls the notification desktop behavior function to transfer the information to the first task management component, and the first task management component records the information according to the task. The stack query determines that the previous application is a video application, so the first task management component sends the application identifier of the video application to the second task management component, and the second task management component calls the query top state function to query the occlusion image display strategy of the video application.

The process of calling 5 and 6 can be regarded as a specific implementation of step A06 in FIG. 7 .

When the user swipes and the finger leaves the screen, the input management module calls 7, and the touch event handles the event triggered by the object leaving the screen, thereby recognizing that the operation performed by the user is a horizontal swipe lift gesture, and then the input management module calls 8, lift Start the gesture recognition function, also known as detectGesture_Up(), and report the horizontal swipe up gesture to the desktop.

The process of calling 7 and 8 can be regarded as a specific implementation of step A07 in FIG. 7 .

After receiving the reported swipe up gesture, the desktop calls 9 to start the subsequent task function, also known as startNextActivity(), to notify the first task management component to start the newly determined application that may be switched, that is, start the above-mentioned step A08. Second application.

In response to the notification from the desktop, the first task management component calls 10, the visualization function, thereby setting the window of the second application to be visible, and the interface information recording component calls 11, the switch window focus function, also known as the updateFocusWindowLocked() switch window focus function For making the interface of the second application to be launched get the focus of the screen, by calling 10 and 11, the WMS can create and display a window for displaying the interface of the second application on the screen of the electronic device.

After the focus is switched, the display content component calls 12 to start the animation function, also known as startAnimation(). By calling the start animation function, the display content component notifies the remote animation component to start the remote animation playback.

After the remote animation component gets the notification to start the remote animation playback, it calls 13 to start the remote animation function, also known as startRemoteAnimation(). By calling 13, the remote animation component controls the Launcher to start playing the animation effect of switching from the first application to the second application. That is, the animation effect of switching from the first application to the second application starts playing from the moment when 13 is called.

In this embodiment, the calling process of the functions 12 and 13 may be regarded as a specific implementation manner of the foregoing step A14.

After the focus is switched, the display content component also calls 14 to obtain the top status function, also known as getCutoutStatus(). By calling function 14, the display content component obtains the occlusion image display strategy of the second application from the second task management component. The occlusion image display policy of the second application is obtained by querying the second task management component when calling function 6 .

The process of invoking 14 can be regarded as a specific implementation manner of the foregoing step A10.

It should be noted that the display content component may call 12 first, then call 14, or call 14 first, then call 12, or call 12 and 14 at the same time, and the specific order is not limited in this embodiment.

After obtaining the occlusion image display strategy of the second application, the display content component determines that the occlusion image needs to be hidden when displaying the interface of the second application according to the occlusion image display strategy, so call 15, the screen edge filter function, also known as notifyControlFilterForSideScreen(), to notify The phone window management component hides the occlusion image. In response to the notification, the phone window management component calls 16, the screen edge visualization function, namely setScreenSideBoxVisibilityAnimation(), thereby informing the system user interface to hide the occlusion image.

The process of calling 15 and 16 can be regarded as a specific implementation of step A11 in the embodiment shown in FIG. 7 .

After getting the notification to hide the occluded image, the system user interface calls 17 to start the hide animation function, also known as StartFadeAnimation(). After that, call 18, hide the animation completion function, also known as fadeAnimationEnd(), to notify that the black bar at the top of the desktop has been completely hidden.

The process of calling 17 and 18 can be regarded as a specific implementation of step A12 in the embodiment shown in FIG. 7 .

In this embodiment, before the desktop starts to play the application switching animation effect, that is, before calling function 13, the display content component notifies the system user interface to start hiding the occlusion image, so that the process of hiding the occlusion image and the process of playing the application switching animation effect can be simultaneously Therefore, the time difference between hiding the occlusion image and the end of the application interface switching is shortened, and the visual effect when the hole-digging screen is switched from an application that is not adapted to the hole-digging screen to an application that is adapted to the hole-digging screen is improved.

According to the foregoing embodiment, a display optimization method during application switching can be obtained. Referring to FIG. 9 , it is a flowchart of a display optimization method during application switching provided by an embodiment of the present application.
