In order to make the objects, features and advantages of the present invention more apparent and understandable, 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, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to solve the defects that the appearance attractiveness and the individualization degree of an electronic device are improved by installing a housing in the related art, and the holding feeling of the electronic device is reduced and aesthetic fatigue is easily caused, a first embodiment of the present application provides a screen saver display method, which is applied to an electronic device having a first display screen on the front side and a second display screen on the back side. In this embodiment, a double-sided electronic device is preferably adopted, and fig. 1 is a schematic diagram of a double-sided electronic device provided in this embodiment, in which a is a front side of the double-sided electronic device, and b is a back side of the double-sided electronic device.
As shown in fig. 2, which is a basic flowchart of the screen saver display method provided in this embodiment, the screen saver display method includes the following steps:
Specifically, in a conventional application scenario, a user usually uses only one of two display screens of the electronic device, that is, a first display screen disposed on a front side of the electronic device is used as a main screen, and a second display screen on a back side of the electronic device is in a standby state. In this embodiment, when the application running on the first display screen is acquired, the application identifier may be an application name, and the application may be in foreground running or background running when the first display screen runs.
In some embodiments of this embodiment, the obtaining the target application currently running on the first display screen includes: acquiring all applications which are currently running in a background of a first display screen; comparing the application priorities of all the applications; and determining the application with the highest application priority as the target application.
Specifically, when the target application is a foreground running application, the target application may be uniquely determined, and when the target application is a background running application, because the background usually runs multiple applications at the same time, the target application needs to be further screened from the multiple applications. In this embodiment, the target application may be determined according to the comparison result of the application priorities of the multiple background running applications, and it should be noted that, in this embodiment, each application priority may be preset by a user, or may be determined by the system in real time according to an application type or an application name of each application, which is not limited uniquely in this embodiment.
In some embodiments of this embodiment, before acquiring the target application currently running on the first display screen, the method further includes: acquiring the on-off state of a screen saver display control; correspondingly, when the switch state is the on state, the step of acquiring the target application currently running on the first display screen is triggered and executed.
