Detailed Description
The invention aims to provide a method for realizing screen burn-in prevention based on application self-management, which effectively solves the screen burn-in problem, prolongs the service life of a screen and improves the use experience of a user. The core idea is as follows: when the application is used, the added view is displayed or hidden in an attribute animation mode, so that the screen burning problem caused by long-time static display of a screen is solved. According to the scheme, after the video playing reaches the threshold value, a manager can automatically hide or display the managed view, automatically match the time length of the fade-in and fade-out animation in proportion according to the time length of the video, and automatically reset the view state when the video is played and finished.
In order to implement the method for implementing anti-burn-in based on application self-management according to the present invention, we need to solve the following problems:
(1) for an application which is in the foreground for a long time and has a relatively fixed interface, it is desirable to manage the relatively fixed interface in the application by itself, and for this, a globally unique manager needs to be established to implement global management.
(2) For the application itself, the information used by the application can be dynamically perceived, including the use time and the application state (such as whether the application is a foreground application).
(3) Views that need custom administration in the application can be dynamically added.
(4) For applications that can repeat loop actions and have different time spans (such as different adaptation of repeated playing time lengths), the views to be managed can be dynamically switched between states with different time consumption according to different time consumption of continuous actions.
In order to solve the above problems, the present invention proposes the following corresponding solutions:
(1) firstly, a manager of a global scope needs to be created, the manager manages the interface of the whole application in an external exposure method mode, and the fixed view is displayed or hidden to achieve the purpose of preventing screen burn by adopting an attribute animation mode and a mode of performing transparency gradual change operation on the managed view.
(2) The method includes the steps that a timestamp variable is maintained in a manager, the application can record the service time of the application through an external exposure method, the view of the management is dynamically removed or added through judgment of the service time, the screen is protected, the screen burning is prevented, and the timestamp in the manager is reset on reasonable occasions of different life cycles of the application, so that the purpose of sensing the service state of the application is achieved.
(3) For views or objects needing to be dynamically added, a hash table is desirably maintained in a manager, and a method for adding members to the table is exposed to the outside, so that views are dynamically added and deleted, and the purpose of management is achieved. And the developer adds the view object to be managed into the manager at a proper application time.
(4) For the application of circularly playing videos, the videos can be repeatedly played under a specific condition, the operation cannot trigger a screen saver program, in this condition, the function of realizing the screen saver by the application is needed, for the videos with different time lengths, how to realize the fade-in and fade-out time of the dynamic control view is realized, therefore, the time length of the video needs to be obtained firstly, then the attribute animation is divided into a plurality of parts by taking a second as a unit, the transparency of the first two parts (namely the first two seconds) is not changed, the transparency of the third second is changed into 0, the view is hidden, finally, the view is displayed in the last second of the video time length, and the process can be repeated for the circularly played videos all the time to achieve the purpose of preventing screen burn.
Example (b):
taking the implementation of the burn-in prevention function on the application as an example, the operation flow from creating the manager, adding the managed view, associating the lifecycle, and then conditionally executing the hidden or displayed view is shown in fig. 1, and is specifically described as follows:
firstly, creating a single-case global manager, maintaining a hash table storage view, managing the view by adopting a mode of setting transparency animation of attribute animation, recording a timestamp variable and a custom global unique constant to serve as conditions for judging whether to execute the attribute animation, exposing the setting and a method for obtaining the timestamp, so that the manager can sense the current state of application, then expose the life cycle of an onPause and an onResume method associated player and application of an attribute animation object, and finally expose a method for setting transparency and configuring the attribute animation object for the view in the hash table.
Secondly, calling an addview method of a manager when the application is initialized, adding a view to be managed into a hash table of the manager, resetting a timestamp in an onResume and a key monitoring method, recording the timestamp of the current system in the playing start state of the player, comparing the timestamp with an original timestamp in the manager, and performing transparency change operation of an interface when the timestamp is greater than a default time threshold; and stopping the animation when the playing is stopped.
Thirdly, dynamically controlling the playing time of the attribute animation is realized by judging the video time; to realize the function, firstly, the attribute animation can be executed in a plurality of shares, the minimum execution time is 3 seconds, the transparency of the views in the hash table is modified in sequence when the transparency animation is executed, the video time is taken as a parameter and is transmitted into the method, the transparency of the first two seconds is kept to be 1 (visible), the transparency of the third second is set to be 0 (invisible), when the time is longer than 3 seconds, the attribute animation is divided into the number of shares of the time size to be executed, the transparency is changed to be 1 in the last second, and an onantiationCancel callback method in an animaliderinerrAdadapter of the attribute animation is set, when the animation is ended, all the transparency of the views is set to be 1, so that the effect that after the set playing of the specified time, the transparency is gradually changed for each time of the video, and after the video playing is ended, the transparency is restored, if no user operation is available, the operation is always circulated to achieve the purpose of protecting the screen.
