Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 problem of large power consumption after the mobile terminal is locked, embodiments of the present application provide a screen locking method for a mobile terminal, a screen locking device for a mobile terminal, and a storage medium, where the screen locking method for a mobile terminal can be applied to a mobile terminal side and executed by the mobile terminal. The mobile terminal in the embodiment may be a portable mobile device such as a mobile phone, a computer, and a tablet computer.
Fig. 1 is a schematic flowchart of a screen locking method of a mobile terminal according to an embodiment of the present application, where as shown in fig. 1, the method includes the following steps:
step S102, when detecting that a user performs screen locking operation on the mobile terminal, adding a black interface on the topmost layer of each interface in the mobile terminal, and setting the black interface to cover a display area of the mobile terminal;
step S104, forcibly stopping each application program running in the mobile terminal by using the acquired equipment authority of the mobile terminal;
step S106, when the black interface receives the touch operation, the touch operation is not responded;
and S108, if the time length of the black interface covering the display area reaches the set time length, controlling the mobile terminal to enter a screen locking state.
In the embodiment of the application, when a user executes a screen locking operation, firstly, a display area of a screen of the mobile terminal is covered by a black interface, secondly, each application program running in the mobile terminal is forcibly stopped, in addition, when the black interface receives the touch operation of the user, the received touch operation is not responded, and finally, when the duration that the display area of the screen is covered by the black interface reaches the set duration, the mobile terminal is controlled to enter a screen locking state. Therefore, according to the embodiment, after the user performs the screen locking operation, each application program running in the mobile terminal can be forcibly stopped, so that the power consumption of the mobile terminal after screen locking is reduced, and the problem of high power consumption of the mobile terminal after screen locking is solved. Moreover, compared with the mode of realizing the screen locking function by the third-party application in the prior art, in the embodiment, when the screen is locked, since the device management authority of the operating system of the mobile terminal cannot be acquired, sensitive data stored on the mobile terminal, such as privacy data of a user, cannot be acquired, so that the privacy of the user is not affected, and the protection of the privacy of the user is facilitated.
In step S102, the screen locking operation may be an operation of pressing a power key, or may be a screen locking gesture preset by a user, such as a sliding gesture performed on a display area of the screen. In one embodiment, the method of fig. 1 is performed by a third-party application, and the screen locking operation is an operation of clicking an icon of the third-party application by a user.
In step S102, when the mobile terminal detects that the user performs the screen locking operation, a black interface is created, where the size of the black interface is the same as the size of the display area of the screen of the mobile terminal, and the mobile terminal adds the black interface to the top layer of each interface in the mobile terminal and sets the black interface to cover the display area of the screen of the mobile terminal, so that the user can see the mobile terminal to display the black interface after performing the screen locking operation, thereby forming a simulated screen locking state.
In one embodiment, the method in fig. 1 is executed by a third party Application program, and after creating a black Interface with the same size as the display area, the third party Application program adds the created black Interface to the current window management system of the mobile terminal by using an Application Programming Interface (API) of an operating system (e.g., an android system) of the mobile terminal, sets the black Interface to be located at the topmost layer of each Interface, and sets the black Interface to cover the display area of the screen of the mobile terminal, so as to complete step S102. When the third-party application sets the black interface to cover the display area of the mobile terminal, the black interface is set to cover the notification bar and the virtual navigation bar of the mobile terminal so as to comprehensively cover the display area of the mobile terminal.
For the currently more-applied OLED (Organic Light-Emitting Diode) screen, each pixel on the screen emits Light independently, in this embodiment, after the user performs the screen locking operation, the display area of the screen of the mobile terminal is covered by the black interface, so that each pixel of the OLED screen is in a non-Light-Emitting state, that is, the whole screen is in a closed state, thereby saving a large amount of electric power by the mobile terminal.
In the step S104, each application program running in the mobile terminal is forcibly stopped by using the acquired device permission of the mobile terminal, specifically, whether an auxiliary function permission of the mobile terminal is acquired is detected, if so, a list of application programs running in the mobile terminal is acquired by using the auxiliary function permission of the mobile terminal, and each application program in the list is forcibly stopped by using the auxiliary function permission of the mobile terminal, so that an operating system of the mobile terminal recovers resources of each application program.
In one embodiment, the screen locking method of the mobile terminal is executed by a third-party application, when the user starts the third-party application for the first time, the application prompts the user whether the user can obtain the auxiliary function permission of the mobile terminal, if the user allows the acquisition, in the step S104, each running application program is forcibly stopped, the auxiliary function permission is continuously obtained, no relevant prompt is performed, if the user refuses the acquisition, each running application program is abandoned, and when the user starts the third-party application for the next time, the user is continuously prompted whether the auxiliary function permission of the mobile terminal can be obtained.
In this embodiment, by forcibly stopping each application running in the mobile terminal, the electric energy of the mobile terminal can be saved, so that after the mobile terminal is in the simulated screen locking state, the electric quantity is further saved.
In the step S106, when the black interface receives the touch operation, the touch operation is not responded, specifically, if it is detected that the user performs the touch operation on the black interface, the black interface is used to receive the touch operation, and the touch operation is not responded, so that a problem that the user wakes up an application program corresponding to a lower interface of the black interface through the touch operation, so that the mobile terminal cannot enter the screen lock state is avoided.
Considering that the touch operation received by the black interface may be a preset unlocking operation or a preset touch operation for invoking a designated function (such as a flashlight or a camera) of the mobile terminal, in this embodiment, the non-response touch operation is specifically to determine whether the received touch operation is a first preset touch operation, where the first preset touch operation includes a preset touch operation for invoking the designated function of the mobile terminal in the screen-locked state, and the preset unlocking operation, if the received touch operation is not the first preset touch operation, the received touch operation is not responded, and otherwise, the corresponding function is implemented in response to the received touch operation.
For example, whether the operation track of the received touch operation is an "O" shaped track or not and whether the received touch operation is a preset unlocking operation or not are judged, if not, the touch operation is not responded, if the operation track is the "O" shaped track, the received sliding operation is responded, the camera function of the mobile terminal is called, and if the operation track is the preset unlocking operation, the black interface is cancelled, and the mobile terminal is controlled to enter an unlocking state.
In this embodiment, by determining whether the received touch operation is the first preset touch operation, it can be ensured that the call and unlock functions of the designated function of the mobile terminal are not affected and the normal use of the mobile terminal is not affected after the mobile terminal is in the simulated screen locking state.
In the step S108, the mobile terminal determines whether the duration of the black interface covering the display area reaches a set duration, for example, 30 seconds, and if so, controls the mobile terminal to enter a screen locking state.
After the black interface covers the screen locking operation of the mobile terminal, the mobile terminal does not respond to the touch operation except the first preset touch operation, so that if the duration that the black interface covers the display area reaches the set duration, which indicates that the user does not effectively operate the mobile terminal after the set duration, the mobile terminal can be controlled to enter a screen locking state, and the mobile terminal can achieve a real screen locking effect. The set time length may be a time length of automatic screen locking, which is a time length of automatic screen locking when no user operation is received within a certain time length preset by the mobile terminal system.
In a specific embodiment, the mobile terminal locks and unlocks a screen by pressing a power key, a touch operation for unlocking is not set, and a touch operation for calling a designated function is not set in the screen locking state, so that after a user clicks an icon of a third-party application, the mobile terminal covers a display area of the mobile terminal by using a black interface, the user sees the black interface to form a simulated screen locking state, then the mobile terminal forcibly stops running each application program by using the acquired auxiliary function authority, receives the touch operation of the user by using the black interface, and does not respond to the received touch operation, and when the duration of the mobile terminal determining that the display area is covered by the black interface reaches 30 seconds, the mobile terminal is controlled to enter the screen locking state, so that the technical effect of realizing one-key screen locking power saving according to the clicking operation of the user is achieved.
In this embodiment, before each application program running in the mobile terminal is forcibly stopped, the running progress of a part or all of the application programs running in the mobile terminal may be cached, and after it is detected that the mobile terminal is switched from the screen locking state to the unlocking state, the part or all of the application programs are recovered according to the cached running progress.
Specifically, before each application program running in the mobile terminal is forcibly stopped, the running progress of part or all of the application programs running in the mobile terminal is recorded and cached, and after the mobile terminal is detected to be switched from a screen locking state to an unlocking state, the part or all of the application programs are recovered according to the cached running progress, so that a user can use the mobile terminal conveniently.
In the embodiment, by caching the running progress of part or all of the application programs running in the mobile terminal and recovering the part or all of the application programs according to the cached running progress after the mobile terminal is unlocked, the mobile terminal can be conveniently used by a user, and the terminal use experience of the user is improved.
In one embodiment, caching the operation progress of a part of application programs operated in the mobile terminal specifically includes: the method comprises the steps of obtaining the use frequency of each application program operated in the mobile terminal, and caching the operation progress of the application program of which the use frequency is greater than the preset frequency.
Specifically, the installation time of each application program is recorded, the starting frequency of each application program is recorded, the installed time length of each application program is determined according to the current time and the installation time of each application program, the use frequency of each application program is determined according to the installed time length of each application program and the starting frequency of each application program, for example, the installed time length of the application program A is 30 days, the starting frequency is 60 times, and the use frequency of the application program is 60/30 times/day.
In this embodiment, before each application program that is forcibly stopped from running, the use frequency of each application program that is running is obtained, for example, if the application program A, B, C is running, the use frequencies of the application programs A, B, C are obtained as 0.5 times/day, 1 time/day, and 2 times/day, respectively, and the preset frequency is 1.5 times/day, the mobile terminal caches the running progress of the application program C, and after it is detected that the mobile terminal is switched from the lock screen state to the unlock state, the application program C is recovered according to the cached running progress.
In the embodiment, the use frequency of each application program running in the mobile terminal is obtained, and the running progress of the application program with the use frequency larger than the preset frequency is cached, so that the running progress of the application program frequently used by a user is cached, the mobile terminal is convenient for the user to use the mobile terminal after the mobile terminal is unlocked, and the terminal use experience of the user is improved.
Or, in another embodiment, caching the operation progress of a part of the application programs operated in the mobile terminal specifically includes: the method comprises the steps of obtaining the average single-use duration of each application program running in the mobile terminal, and caching the running progress of the application program of which the average single-use duration is greater than the preset duration.
Specifically, the usage time length of each application program used by the user each time since installation is recorded, and the average value of the usage time lengths of the respective times of use is taken as the average single-use time length of the application program. For example, if the application a has been used by the user 3 times since installation, and the usage time periods of each time are 30 minutes, 20 minutes and 40 minutes, respectively, the average single-use time period of the application is 30 minutes.
In this embodiment, before each application program that is forcibly stopped from running, the average single-use duration of each application program that is running is obtained, for example, if the application program A, B, C is running, the obtained average single-use duration of the application program A, B, C is 30 minutes, 40 minutes, and 10 minutes, and the preset duration is 20 minutes, the mobile terminal caches the running progress of the application programs a and B, and after it is detected that the mobile terminal is switched from the lock screen state to the unlock state, the application programs a and B are restored according to the cached running progress.
In the embodiment, the average single-use time of each application program running in the mobile terminal is obtained, and the running progress of the application program with the average single-use time being longer than the preset time is cached, so that the running progress of the application program with higher use preference of a user is cached, the mobile terminal is convenient for the user to use the mobile terminal after the mobile terminal is unlocked, and the terminal use experience of the user is improved.
In this embodiment, after the black interface is set to cover the display area of the mobile terminal, the setting information may be displayed on the black interface, and whether the mobile terminal is in the charging state is detected, and if the mobile terminal is not in the charging state, the resolution for displaying the setting information is set to be smaller than the resolution when the mobile terminal is displayed on a bright screen.
The setting information may be time, date, application push message, and the like. After the setting information is displayed, whether the mobile terminal is in a charging state is detected, if the mobile terminal is in the charging state, the resolution for displaying the setting information is set to be the resolution when the mobile terminal is displayed in a bright screen mode, and if the mobile terminal is not in the charging state, the resolution for displaying the setting information is set to be smaller than the resolution when the mobile terminal is displayed in the bright screen mode.
Fig. 2 is a schematic diagram of a mobile terminal displaying setting information on a black interface according to an embodiment of the present application. In the embodiment, the setting information is displayed, so that a user can conveniently acquire necessary information such as time, date and the like, and the user can acquire the information without unlocking the mobile phone. Compared with the mode that the resolution ratio of information display in any state is set by the mobile terminal in the prior art to be the resolution ratio when the information display is in the bright screen display, the resolution ratio of the set information is set to be smaller than the resolution ratio when the information display is in the bright screen display in the uncharged state of the mobile terminal, the power consumption of the mobile terminal can be reduced by reducing the display resolution ratio, and the power consumption of the terminal is reduced under the condition of facilitating the use of the terminal.
For example, a resolution reduction value is preset, and after the setting information is displayed, if the mobile terminal is determined not to be in the charging state, the resolution of the display setting information is obtained by subtracting the set resolution reduction value from the resolution when the mobile terminal is displayed on a bright screen, and the setting information is displayed by using the resolution, so that the display resolution is reduced, and the power consumption of the terminal is reduced.
Fig. 3 is a schematic flowchart of a screen locking method of a mobile terminal according to another embodiment of the present application, and as shown in fig. 3, the method includes the following steps:
step S302, whether a user clicks an icon of the one-key screen locking application is detected.
If yes, go to step S304, otherwise, go back to step S302.
And step S304, generating a black interface, setting the black interface to be positioned at the topmost layer of each interface, and setting the black interface to cover the display area of the mobile terminal.
And step S306, forcibly stopping each application program running in the mobile terminal by using the auxiliary function authority.
In step S308, when it is detected that the user performs a touch operation other than the first predetermined touch operation, the black interface is used to receive the touch operation and does not respond to the touch operation.
In step S310, when it is detected that the user performs the first preset touch operation, it is determined whether the detected touch operation is a preset unlocking operation or a touch operation for invoking a specific function.
The first preset touch operation comprises a preset touch operation for calling the appointed function of the mobile terminal in the screen locking state and a preset unlocking operation.
If the predetermined unlock operation is performed, step S312 is performed, and if the predetermined unlock operation is performed, step S314 is performed.
And step S312, unlocking the mobile terminal.
In step S314, a designated function corresponding to the detected touch operation is called.
Step S316, determining whether the duration of the black interface covering the display area reaches a set duration.
If yes, go to step S318, otherwise, go back to step S316.
