1 is a schematic flowchart of a lock screen control method for an intelligent terminal according to a preferred embodiment of the present invention. The lock screen control method includes the following steps:

S101: Set an application list including at least one application in the smart terminal.

In this embodiment, the smart terminal is a smart device having a display screen, such as a smart phone, a tablet computer, or a multimedia player; the smart terminal runs an operating system, such as an Android operating system, a 10S operating system, and the like. In this step, an application program list is set in the smart terminal, and the application program is a computer software, which is a software program specially developed for a certain application purpose of the user. The application list is a list of information of the application, which is also referred to as a “white list”, including information such as a name, a storage path, an installation time, and the like of the application; the application list includes at least one The application provides the user with an operator interface for the user to select the appropriate application to enter the list. The application is preferably an application that runs for a long time, such as a video player, map navigation, etc., and such an application must continuously display a functional interface while it is running.

S102: Determine, by the task manager in the smart terminal, whether an application in any of the application lists runs.

The operating system of the smart terminal has a task manager for managing running tasks of each application in the smart terminal, for example, sorting tasks of different priorities and allocating system resources, or hanging tasks Start, or keep the task running in the background. The task manager in this step opens the interface so that the third-party software module can obtain the working state of the task manager, such as whether a task is running, suspended, or queued for resource allocation. In this step, the task manager obtains information of the running application and determines whether the application is in the application list. This step continuously queries whether there is an application running in the application list according to a time period, and if so, proceeds to a subsequent step, wherein the time period is preferably within 0.1 second, so as to detect the application in time. run.

S103: Record the running time of the application when there is an application running in any of the application lists.

This step is performed when it is determined in step S102 that there is an application running in any of the application lists. The running time refers to the time from the start of the application to the end of the running, such as the duration of the video player playing a video, or the time when the map navigation continues from the start of the departure to the end of the navigation. This step Recording the running time is: first, detecting, by the task manager, a time when the application is running as a starting time, and then starting timing, and when the task manager detects that the application ends running, terminating The running time can be obtained by timing. At the beginning, the system time can be obtained from the application interface opened by the operating system, and the system time is acquired again at the end, and the running time can be obtained by subtracting the time between the two times. There is also a timing mode in which a timer program is run from the start time, and the timer is stopped when the application ends running, that is, the running time is obtained. The timer may be an independent program module, or may be configured to set a timed task, the timed task is triggered according to a time period, and the running time is accumulated every time the trigger is performed.

S104: Determine whether the running time is greater than a time threshold preset in the smart terminal.

A time threshold is preset in the smart terminal. In this step, it is determined whether the running time recorded in step S103 is greater than the time threshold. The purpose of this step is to distinguish between applications that are running for a long time so that subsequent steps can process the application.

S105: When the running time is greater than the time threshold, after the application ends running, controlling, by the framework layer of the operating system in the smart terminal, the smart terminal enters a lock screen state, and the display is preset to the The lock screen interface in the smart terminal.

When the step S104 determines that the running time is greater than the time threshold, the step is performed. Another condition that is executed in this step is that the application ends the operation, and the condition does not conflict with the running time judgment in step S104, and the running time of the application can be recorded only after the application ends running, and thus the The running time is judged with the time threshold. The execution of the step is to control the smart terminal to enter the lock screen state. The implementation manner is to control the smart terminal to enter the lock screen state through a framework layer in the operating system. In the Android operating system, the framework layer, the Framework, provides a series of service and API interfaces for developers of application development, allowing developers to obtain and modify operating parameters of the operating system and perform functions based on the original operating system. Expansion. The frame layer can also control the lock screen state of the smart terminal. In this step, an operation command is sent to the frame layer through the interface, and the smart terminal is controlled to enter the lock screen state. After the smart terminal enters the lock screen state, a pre-stored lock screen interface is displayed on the screen, and the lock screen interface only receives a specific unlocking operation, and does not receive any other operations, so as to protect the desktop of the smart terminal or Other display interfaces are not exposed to the outside, protecting the user's private information.

S106: The lock screen interface receives an unlocking operation.

When the smart terminal is in the lock screen state, the lock screen interface can receive an unlock operation. The unlocking operation may be a sliding touch operation, or may be a digital password input or a graphic input according to the prompt of the lock screen interface. When the unlocking operation is a touch operation, the lock screen interface displays a slider and a long slot. The user has to drag the slider to move to the end position in the slot to achieve unlocking; when the unlocking operation is a digital password input, the lock screen interface displays a numeric button of 0-9, and the user can input a preset. The unlocking password is unlocked; when the unlocking operation is graphic input, the lock screen interface displays dots or circles arranged in a matrix form, and the user can perform a sliding touch operation to sequentially connect points or centers of different positions in a sequence, if a touch operation The trajectory is the same as the preset unlock trajectory, and unlocking is achieved.

S107: Control, by the framework layer, the smart terminal to enter an unlocked state, and start a desktop launcher in the smart terminal to display a desktop.

If the unlocking operation in step S106 is correct, this step is performed. In this step, the unlocking operation is performed, that is, the smart terminal is controlled to enter an unlocked state by the frame layer, and an unlocking instruction is sent to the frame layer through the interface, and the framework layer controls the smart terminal to enter an unlocked state, and the Lock screen interface. Then, this step starts a desktop launcher (Launcher) in the smart terminal to display the desktop. The desktop launcher is one of the main program components in the Android system, and manages the display content of the desktop, and the application developer can write content that needs to be displayed on the desktop, such as an application icon, in the desktop launcher. When the smart terminal is in the lock screen state, the desktop launcher does not start, and the step starts the desktop launcher to perform desktop display, and wakes up the running task of the desktop launcher.

In some implementations of the first aspect of the present application, determining whether the running time is greater than a time threshold preset in the smart terminal, the time threshold is a preset non-operation in the smart terminal. The standby time of the automatic lock screen. The preferred embodiment preferably optimizes the time threshold in step S104 of FIG. 1, and the time threshold is the standby time of the automatic lock screen when the erroneous operation is performed. The prior art provides a lock screen mode for automatic lock screen, that is, when the smart terminal is on the desktop, if the external operation is not received for a period of time, the lock screen state is automatically entered, and the standby time is available at the smart terminal. Internal settings, such as 30 seconds, 1 minute, etc. In the embodiment, the time threshold is equal to the standby time, that is, when the smart terminal runs the application, the standby time of the automatic lock screen is also applicable, and the difference is that the lock screen is not executed when the application ends running. The operation, rather than the runtime, reaches the time threshold and performs a lock screen operation.

In some embodiments of the first aspect of the present application, when the lock screen interface receives an unlocking operation, the unlocking operation may be a sliding operation or a digital password input operation for the lock screen interface. The preferred embodiment preferably optimizes the unlocking operation, which is preferably a sliding operation or a digital password input operation. The sliding operation is performed on the lock screen interface, for example, a slider is displayed on the lock screen interface, and the slider is located at one end of a groove-shaped area, and the user must perform a drag operation on the slider, and drag To the other end of the trough-like area, the unlocking is considered successful. When the digital password input operation is performed, a set of 0-9 numbers is displayed on the lock screen interface, and the user must input A set of preset numeric passwords can be unlocked.

Referring to FIG. 2, it is a schematic diagram of a specific process in step S103 in FIG. 1 in accordance with a preferred embodiment of the present invention. Step S103 includes:

S103-1: Record the time when the application starts running as the start time.

This step records the time the application started running, the first time it was detected that the application started running. The way to obtain the time is to obtain the system time as the starting time through the interface open by the operating system.

S103-2: Detect whether the running state of the application ends.

During the execution of the step, the running state of the application is continuously detected according to a time period. The detecting manner is to obtain the running state of the application by using the task manager, so as to know whether the application is running or It is the end of the run. The time period is at most 0.1 seconds in order to discover in time that the application ends running.

S103-3: When the running state of the application ends, the current time is recorded as the ending time.

When step S103-3 determines that the running state of the application is over, this step is performed. This step records the end of the running state of the application as the end time. The implementation method is to obtain the system time as the end time through the interface opened by the operating system.

S103-4: Subtracting the end time from the start time to obtain the running time.

This step performs a calculation operation, and the content of the calculation operation is to subtract the start time from the end time to obtain the running time. For example, the end time is 15:30, and the start time is 15:10, and the time difference obtained by subtracting the two is 20 minutes, that is, the running time is 20 minutes.

3 is a schematic flowchart of a lock screen control method for a smart terminal according to another preferred embodiment of the present invention. The lock screen control method further includes the following steps:

S108: When the running time is not greater than the time threshold, the desktop launcher displays the desktop after the application ends running.

When step S104' determines that the running time is not greater than the time threshold, this step is performed. This step displays the desktop by launching the desktop launcher after the application finishes running. The effect of this step is that after the application is finished running, if the running time is not greater than the time threshold, the desktop is displayed, and the lock screen state is not entered.
