Disclosure of Invention

In order to solve the technical problems, the application provides a method for displaying a multi-task interface, electronic equipment and a storage medium, so that when the electronic equipment enters the multi-task interface, the dynamic special effect of the multi-task interface is smooth.

In a first aspect, the present application provides a method for displaying a multitasking interface, applied to an electronic device, including: if the wallpaper management module detects an instruction for indicating wallpaper initialization, a first acquisition request is sent to a target service, wherein the first acquisition request is used for indicating acquisition of a target image, and the target service is wallpaper service matched with the current wallpaper type adopted by the electronic equipment; the target service responds to the first acquisition request and acquires an image from wallpaper currently adopted by the electronic equipment as a first image; the target service acquires the first image after the blurring process as a target image and returns the target image to the wallpaper management module; the wallpaper management module transmits the target image to a desktop, and the desktop caches the target image; and if the desktop detects the multitasking operation of the user, acquiring the stored target image as a background image of the multitasking interface.

Thus, when the wallpaper management module detects an instruction indicating wallpaper initialization, the wallpaper management module requests acquisition of a target image and stores the target image through the desktop. In this example, the electronic device obtains the first image and performs the blurring process on the first image, which is performed when the wallpaper management module is initialized, but not when the multitasking operation is detected, so that the electronic device does not need to obtain an image to be processed when entering the multitasking interface, and does not need to perform the blurring process on the obtained image, thereby reducing the steps of displaying the background image of the multitasking interface, reducing the operation amount of the electronic device, further enabling the electronic device to have sufficient operation amount when displaying the animation special effect on the multitasking interface, and avoiding the problems of blocking and unsmooth animation special effect in the multitasking interface. Meanwhile, the target image is a first image after blurring processing, and the first image is one image in wallpaper adopted by the electronic equipment, so that the electronic equipment does not need to carry out screen capturing operation no matter the wallpaper adopted by the electronic equipment is dynamic wallpaper or static wallpaper, the step of acquiring the first image is further reduced, and the power consumption of the electronic equipment is reduced.

According to a first aspect, before the target service acquires the blurred first image as the target image, the method further comprises: the target service sends a first processing instruction to the wallpaper processing module, wherein the first processing instruction indicates that image compression processing is performed on a first image; the wallpaper processing module responds to the first processing instruction and performs an image compression instruction on the first image; the wallpaper processing module returns the compressed first image to the target service; the target service obtains the compressed first image as a new first image.

Thus, the wallpaper processing module firstly performs image compression processing on the first image, so that the resolution of the image can be reduced, and the capacity of the first image can be reduced. The electronic equipment performs blurring processing on the first image after image compression, and as the resolution of the first image is reduced, the processing amount of Gaussian blurring can be further reduced, the processing speed of the first image is improved, and the power consumption of the electronic equipment for processing the first image is reduced.

According to a first aspect, before sending the first acquisition request to the target service, the method further comprises: if the wallpaper management module detects an instruction for indicating wallpaper initialization, acquiring a wallpaper type currently adopted by the electronic equipment, wherein the wallpaper type comprises: static wallpaper type, dynamic wallpaper type and super wallpaper type; if the wallpaper management module detects that the wallpaper type is the static wallpaper type, acquiring a static wallpaper service as a target service; if the wallpaper management module detects that the wallpaper type is the dynamic wallpaper type, acquiring dynamic wallpaper service as target service; and if the wallpaper type is detected to be the super wallpaper type, the wallpaper management module acquires super wallpaper service as target service.

Thus, the wallpaper management module obtains the wallpaper service matched with the wallpaper type according to different wallpaper types, and as different wallpaper types correspond to different wallpaper services, the target service can obtain an accurate first image no matter whether the wallpaper currently adopted by the electronic equipment is dynamic wallpaper, static wallpaper or super wallpaper through the wallpaper service matched with the wallpaper type.

According to a first aspect, the target service, in response to a first acquisition request, acquires, as a first image, an image from wallpaper currently employed by the electronic device, including: the target service sends a second acquisition request to the wallpaper processing module; the wallpaper processing module responds to a second acquisition request, and the static wallpaper is adopted from the electronic equipment, wherein the static wallpaper comprises an image; the wallpaper processing module returns the static wallpaper to the target service; the target service obtains the static wallpaper as a first image.

Fig. 1 is a schematic illustration of a scenario for entering a multi-tasking interface, which is schematically illustrated. In this example, the electronic device uses a mobile phone as an example, as shown in fig. 1, a display screen of the mobile phone displays a main screen interface 101, where the main screen interface includes application icons of each application, such as an icon of a clock application, an icon of a calendar application, and the like. As shown in fig. 1a, the user may click on an icon of the clock application, and the mobile phone starts the clock application in response to the clicking operation of the user, as shown in fig. 1b, and the display screen in fig. 1b displays the clock interface 102. The user may click a back button in the handset to return to the home screen interface 101. The user may click on an icon of the calendar application in the main screen interface 101, and the handset starts the calendar application in response to the user clicking on the icon of the calendar application, as shown in 1c of fig. 1, the display screen displaying the calendar interface 103. The user can input a multitasking operation, as shown in fig. 1c, the user can slide up in the direction of the black arrow, and the mobile phone responds to the user's up-sliding operation to enter the multitasking interface. As shown in fig. 1d, a multi-task interface 104 is displayed in the display screen of the mobile phone, where the multi-task interface includes an interface thumbnail of an application running in the background of the mobile phone, and as shown in fig. 1d, the mobile phone runs a calendar application, a clock application, and a setting application before entering the multi-task interface, where the three applications run in the background when the mobile phone returns to the main screen interface. When the mobile phone enters the multi-task, the multi-task interface 104 displays the interface thumbnails of the three applications running in the background in the multi-task interface with animation special effects, for example, when entering the multi-task interface, the thumbnails of the clock interface, the thumbnail of the setting interface and the thumbnail of the calendar interface are sequentially displayed in the display screen.

The background image of the multi-task interface is typically determined from the wallpaper of the current handset. The method includes the steps that when a mobile phone detects the operation of multitasking, whether the current wallpaper of the mobile phone is static wallpaper is detected, if the mobile phone is determined to be the static wallpaper type, the static wallpaper is obtained from wallpaper resources of the mobile phone, fuzzy processing is conducted on the static wallpaper, and the static wallpaper after the fuzzy processing is obtained to serve as a background image of a multitasking interface. If the mobile phone determines that the wallpaper is of a non-static wallpaper type (such as a super wallpaper type or a dynamic wallpaper type), the mobile phone performs screen capturing operation on the currently adopted wallpaper, performs fuzzy processing on the screen capturing image, and takes the screen capturing image after the fuzzy processing as a background image of the multi-task interface. When the multitasking operation is detected, the mobile phone needs to perform the operation, and the fuzzy processing further increases the operation amount of the mobile phone, so that the problems of frame loss and blocking occur when the background application interface thumbnail is displayed in an animation form on the background image of the multitasking interface, the background application interface thumbnail is not smoothly displayed, and the use experience of the mobile phone card is left for the user.

The embodiment of the application provides a method for displaying a multi-task interface, which is executed by electronic equipment, so that when the electronic equipment enters the multi-task interface, the problem of blocking and frame loss of interface thumbnails of a background application can not occur during animation display, the smoothness of displaying the interface thumbnails of the background application is improved, and the use experience of a user in using the electronic equipment is improved.

FIG. 4 is a schematic diagram of an exemplary illustrated method of multitasking interface display. In this example, the electronic device is exemplified by a mobile phone. As shown in fig. 4, when the user performs the sliding-up operation, the wallpaper manager may determine a policy for obtaining wallpaper according to different wallpaper types. If the wallpaper manager detects that the static wallpaper type is adopted currently, the wallpaper manager can acquire the static wallpaper from the system, and the static wallpaper is a two-dimensional image and can be used as a first image to be processed. If the wallpaper manager detects that the super wallpaper type is adopted currently, the last displayed image in the super wallpaper adopted by the mobile phone can be obtained as the first image. Wherein, include many different pictures in the super wall paper. If the wallpaper manager detects that the current dynamic wallpaper type is adopted, the dynamic video adopted by the current mobile phone can be analyzed, and the last frame of image in the dynamic video is obtained as a first image.

As shown in fig. 4, the wallpaper manager may perform 100 times image compression on the first image to reduce pixels in the first image. The wallpaper manager performs blurring processing on the compressed image, and the blurring processing mode can adopt Gaussian blurring. The wallpaper manager caches the blurred image and takes the cached image as a target image. When the desktop detects the multi-task operation, the desktop can acquire the cached target image as a background image of the multi-task interface, and refreshing of the background image is completed.

The following describes a specific flow of the method of the multi-task interface in detail with reference to fig. 5, and fig. 5 is a flow chart illustrating a method of displaying a multi-task interface. The method for displaying the multi-task interface is applied to electronic equipment, and the electronic equipment can be a mobile phone, a tablet personal computer and the like. The method for displaying the multi-task interface comprises the following steps:

step 401: if the wallpaper management module detects an instruction for indicating wallpaper initialization, a first acquisition request is sent to a target service, wherein the first acquisition request is used for indicating acquisition of a target image, and the target service is wallpaper service matched with the current wallpaper type adopted by the electronic equipment.

In this example, the electronic device is illustrated as a mobile phone, and the wallpaper manager of the mobile phone includes a desktop, a wallpaper management module, each wallpaper service, and a wallpaper processing module (i.e., wallpaper tool class). If the desktop of the mobile phone detects a starting or restarting operation, the desktop performs an initializing operation and requests to acquire wallpaper to be displayed from the wallpaper management module.

The request obtained by the wallpaper management module may instruct the wallpaper management module to perform wallpaper initialization. After receiving the instruction for indicating the wallpaper initialization, the wallpaper management module can acquire the wallpaper type adopted by the current mobile phone, initialize the wallpaper according to the wallpaper type, generate wallpaper service matched with the wallpaper type, and take the wallpaper service matched with the wallpaper type as target service. For example, if the wallpaper type of the wallpaper adopted by the mobile phone is a static wallpaper type, the wallpaper management module initializes the static wallpaper management class, so that a static wallpaper instance (i.e. a static wallpaper service in the application) can be generated. Wallpaper service can be understood as a wallpaper instance, and other modules can be called to acquire wallpaper or to perform image processing on the wallpaper.

In this example, the wallpaper types include: static wallpaper type, dynamic wallpaper type, and super wallpaper type. If the wallpaper management module detects that the wallpaper type is the static wallpaper type, determining the static wallpaper service as a target service; if the wallpaper management module detects that the wallpaper type is the dynamic wallpaper type, determining the dynamic wallpaper service as a target service; and if the wallpaper type is detected to be the super wallpaper type, the wallpaper management module determines super wallpaper service as target service.

After the wallpaper manager initiates the operation, a first acquisition request may be generated requesting acquisition of the target image. Optionally, the target image is a first image after blurring processing, and the first image is an image obtained from wallpaper adopted by the mobile phone.

Step 402: the target service responds to the first acquisition request and acquires an image from wallpaper currently adopted by the electronic equipment as a first image.

For example, the target service may send a wallpaper acquisition request to the wallpaper processing module. And after receiving the wallpaper acquisition request, the wallpaper processing module sends an access request to the system extension class to request to access wallpaper resources. The system extension class can acquire the wallpaper adopted by the mobile phone currently and return to the wallpaper processing module. The wallpaper processing module can acquire an image from the wallpaper currently adopted by the mobile phone equipment according to the acquired wallpaper and return to the target service.

Specifically, if the target service is a static wallpaper service, the static wallpaper service may send a second acquisition request to the wallpaper processing module, where the second acquisition request is used to request wallpaper currently employed by the mobile phone. The wallpaper processing module sends an access request to the system extension class in response to the second acquisition request. The system extension class can acquire the static wallpaper adopted by the mobile phone currently and return the static wallpaper to the wallpaper processing module. The wallpaper processing module may return the static wallpaper to a target service, the target service having the static wallpaper as the first image.

In one example, if the target service is a super wallpaper service, the super wallpaper service may send a second acquisition request to the wallpaper processing module, the second acquisition request requesting wallpaper currently employed from the handset. The wallpaper processing module responds to a second acquisition request, and static wallpaper adopted by the electronic equipment at present is taken as a first image, wherein the static wallpaper comprises an image; the wallpaper processing module returns the first image to the target service; the target service obtains a first image.

Specifically, if the target service is a super wallpaper service, the super wallpaper service may send a third acquisition request to the wallpaper processing module, where the third acquisition request is used to request wallpaper currently adopted by the mobile phone. The wallpaper processing module sends an access request to the system extension class in response to the third acquisition request.

The ratio of the image compression may be 10×10 to 30×30. The image compression mode is to perform frame loss processing on the image so as to reduce the resolution of the image and reduce the capacity of the first image.

After the target service obtains a new first image, a second processing instruction is sent to the wallpaper processing module, and the second processing instruction indicates the blurring process to the first image; the wallpaper processing module responds to the second processing instruction to perform Gaussian blur operation on the first image; the wallpaper processing module returns the image after the blurring processing to the target service; the target service acquires the first image after blurring processing.

In this example, the wallpaper processing module performs image compression processing on the first image, so that the resolution of the image can be reduced, and the capacity of the first image can be reduced. And then the first image after the image compression is subjected to blurring processing, and as the resolution of the first image is reduced, the Gaussian blurring processing amount is further reduced, the processing speed of the first image is improved, and the power consumption of the mobile phone for processing the first image is reduced.

Optionally, the target service may further send a second processing instruction to the wallpaper processing module after the first image is acquired. The wallpaper processing module directly carries out blurring processing on the first image and returns the first image after blurring processing to the target service. And the target service takes the first image after the blurring process as a target image and returns the target image to the wallpaper management module.
