Detailed Description
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.
The embodiment of the application provides a display control method, which is applied to an electronic device, wherein the electronic device can be a mobile phone, a tablet computer, a notebook computer, a computer or other devices with interface display functions.
Referring to fig. 1, the display control method in the present embodiment mainly includes the following steps:
step 101, monitoring a process state of an electronic device;
a process is a basic unit of program operation embodied by an operating system, and is a basic unit of resource allocation and scheduling of a program with respect to one operation activity on a certain data set.
When the electronic device is in a power-on state, one or more processes are run on the electronic device. And the process state reflects changes in the process execution. The process state transitions with the execution of the process and changes in external conditions.
In step 101, the process state of the electronic device is monitored, so that the execution of the subsequent steps is triggered based on the monitored process state.
Since the interface displayed by the electronic device has a related process, in step 101, only the process state related to the current interface of the electronic device may be monitored, and of course, in step 101, the process state of each process currently running by the electronic device may also be monitored, which is not limited herein.
Because the interface displayed by the electronic device can be divided into a full-screen displayed interface or a non-full-screen displayed interface (such as a small window displayed interface), and the non-full-screen displayed interface is usually displayed in a partial area of the full-screen displayed interface, even if the non-full-screen displayed interface is destroyed, the phenomenon of black flashing does not occur. Therefore, in a scenario of monitoring only the process state related to the current interface of the electronic apparatus, optionally, only the process state of the process related to the interface displayed in the full screen currently by the electronic apparatus may be monitored.
Due to logic errors of the program or other reasons, one or more processes related to the program may need to be forcibly ended, and at this time, whether the process which is forcibly ended exists in the electronic device can be known by monitoring the process state of the electronic device. Specifically, when a process needs to be forced to end, the electronic device typically receives a process forced end signal (e.g., a SIGKILL signal under the android system, see 9 in table 1)) indicating that the electronic device is forced to end the process. Therefore, in step 101, it may be monitored whether the electronic apparatus receives a process force end signal, and if it is monitored that the electronic apparatus receives the process force end signal and a process indicated by the process force end signal is a process related to the current interface of the electronic apparatus, it is determined that the process related to the current interface of the electronic apparatus is monitored to be forcibly turned off.

102, detecting whether a target interface exists in the electronic device when monitoring that a process related to the current interface of the electronic device is forcibly ended;
in the embodiment of the present application, the target interface is an interface different from the current interface and set to be full screen visible. Based on an interface management mechanism of the electronic device, when the interface is set to be full-screen visible, the interface is displayed on the electronic device in a full-screen manner, under a normal condition, corresponding zone bits exist in each interface, and the corresponding interface can be set to be full-screen visible, non-full-screen visible or invisible by setting the zone bits.
In step 102, data in a window management module of the electronic device may be retrieved to detect whether a target interface exists in the electronic device.
103, when the target interface does not exist in the electronic device, controlling the electronic device to keep displaying the current interface;
when step 102 detects that the electronic device does not have the target interface, the electronic device may be considered to have no or not read the next full-screen visible interface, and at this time, the electronic device is controlled to keep the display of the current interface, that is, the current interface is not destroyed temporarily, even if the current interface is reset to be invisible.
Optionally, the controlling the electronic device to maintain the display of the current interface may include: and screenshot is carried out on the current interface, the electronic device is controlled to display the screenshot of the current interface and destroy the current interface. Alternatively, the electronic device may be controlled to temporarily not destroy the current interface, which is not limited herein.
Further, after step 103, immediately, or after waiting for a preset duration or a preset event, continuously detecting whether the electronic apparatus has a target interface, and when detecting that the electronic apparatus has the target interface, controlling the electronic apparatus to delete a screenshot of the current interface or destroy the current interface, so that the electronic apparatus displays the target interface.
Optionally, after step 102, if it is detected that the target interface exists in the electronic apparatus, the electronic apparatus may be controlled to destroy the current interface, or the electronic apparatus may be controlled to display the current interface in a windowed manner and destroy the current interface after waiting for a preset time period, which is not limited herein.
As can be seen from the above, the embodiment of the application monitors the process state of the electronic device by monitoring; when monitoring that the process related to the current interface of the electronic device is forcibly ended, not destroying the current interface immediately, but further detecting whether a target interface exists in the electronic device; and if the target interface does not exist in the electronic device, controlling the electronic device to keep displaying the current interface. Because the target interface is different from the current interface and is set to be a full screen visible interface, when the electronic device is detected to have no target interface, the electronic device can be considered to have no or not read the next full screen visible interface, at the moment, the display of the current interface is kept by controlling the electronic device, the phenomenon that the current interface of the electronic device is destroyed to be black can be avoided, and further, the phenomenon of black flash can be avoided.
The embodiment of the present application provides a display control method, and a difference between the embodiment of the present application and the foregoing embodiment is that, in the embodiment of the present application, it is monitored that a process related to a current interface of the electronic apparatus is forcibly ended, and the current interface is a full-screen visible interface, whether a target interface exists in the electronic apparatus is detected. Therefore, the detection action can be reduced when the current interface is not the full-screen visible interface, and the purpose of saving power consumption is achieved. Referring to fig. 2, the display control method in the present embodiment mainly includes the following steps:
step 201, monitoring the process state of the electronic device;
specifically, step 201 may refer to the description of step 101 in the embodiment shown in fig. 1, and is not described herein again.
Step 202, detecting whether a target interface exists in the electronic device when monitoring that a process related to a current interface of the electronic device is forcibly ended and the current interface is a full-screen visible interface;
in the embodiment of the application, when it is monitored that the process related to the current interface of the electronic device is forcibly ended, whether the current interface is a full-screen visible interface is further detected, and specifically, whether the current interface is a full-screen visible interface can be determined by detecting a specific flag bit of the current interface.
When it is detected that the current interface is a full-screen visible interface, detecting whether a target interface exists in the electronic apparatus, where the description of the target interface may refer to the description of step 102 in the embodiment shown in fig. 1, and details are not described here again.
When the current interface is detected to be a full screen visible interface, the action of detecting whether the electronic device has the target interface is not executed, and at the moment, the electronic device destroys the current interface according to self logic.
Step 203, when the target interface does not exist in the electronic device, controlling the electronic device to keep displaying the current interface;
specifically, step 203 may refer to the description of step 103 in the embodiment shown in fig. 1, and is not described herein again.
As can be seen from the above, the embodiment of the application monitors the process state of the electronic device by monitoring; when monitoring that the process related to the current interface of the electronic device is forcibly ended and the current interface is a full-screen visible interface, not immediately destroying the current interface, but further detecting whether a target interface exists in the electronic device; and if the target interface does not exist in the electronic device, controlling the electronic device to keep displaying the current interface. Because the target interface is different from the current interface and is set to be a full screen visible interface, when the electronic device is detected to have no target interface, the electronic device can be considered to have no or not read the next full screen visible interface, at the moment, the display of the current interface is kept by controlling the electronic device, the phenomenon that the current interface of the electronic device is destroyed to be black can be avoided, and further, the phenomenon of black flash can be avoided. In addition, only when the current interface is the full-screen visible interface, whether the target interface exists in the electronic device is detected, so that the detection action can be reduced when the current interface is the non-full-screen visible interface, and the purpose of saving power consumption is achieved.
