Detailed Description
In order to make the objects, features and advantages of the embodiments of the present application more obvious and understandable, 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 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 the description of the present application, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present application, it is noted that, unless explicitly stated or limited otherwise, "including" and "having" and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
In the android system, the conventional User Interface (UI) refresh scheme is mainly a manner of refreshing at intervals. If the refresh rate is 60Hz, a vsync signal is sent to the bottom layer every 16ms or so, and the display will fetch data from the buffer and then display a frame of picture. When the vsync signal arrives, the processor executes the work of the next frame of picture, which mainly comprises executing application animation (animation) callback and executing UI drawing, and the work needs to be finished in corresponding time (when the refresh rate is 60Hz, the time is about 16 ms). If animation and UI drawing are not completed in the current 16ms time period, that is, the work is overtime, and when the next vsync signal arrives, the display cannot acquire the data of the frame of picture from the buffer, and cannot display the frame of picture, the problem of frame dropping occurs. The problem of working timeout occurs mainly because animation callback takes a lot of time, and in many cases, because animation callback takes too long time, and then when the next vsync signal arrives, UI drawing is not completed, which causes application refresh timeout, thereby causing a problem of frame dropping.
The present application will be described in detail with reference to specific examples.
In the following method embodiments, for convenience of description, only the execution subject of each step is taken as a terminal for description.
Fig. 1 is a schematic flow chart of a picture drawing method according to an embodiment of the present disclosure. As shown in fig. 1, the method of the embodiment of the present application may include the steps of:
s101, determining the drawing completion time of the current interface of the current synchronization period, and determining the arrival time of the next synchronization signal of the next synchronization period.
It is to be understood that a synchronization period refers to a time period corresponding to the time period between two vsync signals. The current synchronization period may be a synchronization period that is currently being experienced at the current time. The next synchronization period may be the next synchronization period after the current synchronization period. In the process of refreshing the UI, for example, the screen refresh rate is 60Hz, a vsync synchronization signal arrives every 16ms or so, when each vsync synchronization signal arrives, the display needs to acquire data of a current frame of picture from a buffer and then display the current frame of picture, and meanwhile, the processor needs to do refresh preparation work of the next frame of picture, which mainly comprises animation echo and UI drawing. Therefore, the current interface drawing can be the UI drawing which needs to be executed by the terminal in the current synchronization period, and the current interface drawing completion time can be the corresponding time point when the current UI drawing is completed. The next synchronization signal may be a next vsync signal, and the arrival time of the next synchronization signal may be a time point corresponding to the arrival time of the next vsync signal.
For example, referring to the schematic diagram of the drawing of the picture shown in fig. 2, the synchronization signal indicates a vsync signal, when each synchronization signal arrives, the display needs to obtain data of a "current frame picture" from the buffer, and then display the "current frame picture", and at the same time, the processor needs to start to perform preparation work of a "next frame picture", which mainly includes animation blending and interface drawing, and when a next synchronization signal arrives, the display can obtain data of the "next frame picture", and then display the "next frame picture", and the processor simultaneously performs corresponding work, and the screen refresh can be realized by repeatedly performing the operations. In fig. 2, the time period between the synchronization signal 1 and the synchronization signal 2 can be referred to as a current synchronization period, and then the time period between the synchronization signal 2 and the synchronization signal 3 is referred to as a next synchronization period, and the arrival time of the synchronization signal 2 is the arrival time of the next synchronization signal.
In some embodiments, in a screen refreshing process of the terminal, the terminal may directly obtain a time point when the current interface drawing execution is completed in the current synchronization period, that is, a current interface drawing completion time. The terminal may also calculate a time point when the next synchronization signal of the next synchronization period arrives, that is, the arrival time of the next synchronization signal. Generally, the duration corresponding to one synchronization period may be the reciprocal of the screen refresh rate, and the next arrival time of the synchronization signal may be obtained by adding the duration corresponding to one synchronization period to the current arrival time of the synchronization signal.
And S102, starting to execute the animation callback of the next synchronization cycle in the idle time between the current interface drawing completion time and the next synchronization signal arrival time, and executing the interface drawing of the next synchronization cycle after the animation callback is completed.
In some embodiments, in the current synchronization cycle, the processor generally executes an animation callback, and after the animation callback is executed, the current interface drawing is started to be executed, and after the current interface drawing is executed, the current synchronization cycle is not finished yet, that is, a time point corresponding to the time point when the current interface drawing is completed is still within the time of the current synchronization cycle, so that a time period between the time point when the current interface drawing is completed and the time point when the next synchronization signal arrives is called an idle time, and the time point when the next synchronization signal arrives is a start point of the next synchronization cycle. In the related art, in the current synchronization cycle, if there is idle time, the processor waits until the next synchronization signal arrives to start execution of an animation callback of the next synchronization cycle, and executes interface drawing of the next synchronization cycle after the execution of the animation callback of the next synchronization cycle is completed. In the solution of the embodiment of the present application, in the current synchronization cycle, if there is idle time, the animation callback of the next synchronization cycle may be executed in the idle time, and the interface drawing of the next synchronization cycle is executed after the animation callback is completed.
When the scheme of the embodiment of the application is executed, the current interface drawing completion time of the current synchronization period and the next synchronization signal arrival time of the next synchronization period are determined, the animation callback of the next synchronization period is started to be executed in the idle time between the current interface drawing completion time and the next synchronization signal arrival time, and the interface drawing of the next synchronization period is executed after the animation callback is completed. According to the method and the device, the mode that the next synchronization period of the animation callback is advanced to the idle time in the current synchronization period to start execution is adopted, the next synchronization period of the interface drawing is executed after the next synchronization period of the animation callback is completed, the probability that the overtime of the interface drawing is completed due to too long time consumed by the animation callback can be reduced, the probability of application refresh overtime can be reduced, and the probability of frame dropping can be reduced.
Please refer to fig. 3, which is a flowchart illustrating a picture drawing method according to an embodiment of the present disclosure. As shown in fig. 3, the method of the embodiment of the present application may include the steps of:
s301, receiving sliding operation aiming at the display interface, and acquiring the execution times of the animation callback in the current synchronization period.
It is to be understood that the display interface may be a UI interface displayed on the terminal. The sliding operation may be a touch operation performed on the UI interface, for example, the sliding operation may be a touch operation performed in a vertical direction, a touch operation performed in a horizontal direction, or a touch operation performed in an arbitrary direction and at an arbitrary angle.
The number of executions may be expressed as how many animation callbacks are executed in the current synchronization cycle.
The synchronization period may be a time period corresponding to a time period between two vsync signals.
In some embodiments, the applicable application scenario may be that the user performs a sliding operation on the display interface. Generally, a user executes a sliding operation on a display interface, a terminal needs to load a large amount of content and display the content in response to the sliding operation, and if the design optimization of an application program is not good, an animation callback is too long when a screen is refreshed in the scene, so that the problems of application refresh timeout and frame drop occur. In order to reduce the probability of frame drop in this scenario, the number of times of execution of the animation callback in the current synchronization period may be obtained when the sliding operation of the user on the display interface is received. In a specific scene, the steps of the scheme are executed, so that the resources of the terminal can be saved, and the resource consumption caused by the execution of the scheme in some scenes without optimizing dropped frames is avoided.
And S302, if the execution times are less than the preset times, determining the current interface drawing completion time of the current synchronization period and determining the next synchronization signal arrival time of the next synchronization period.
It can be understood that the preset number of times can be set to 2, and then the number of times of execution can only be 1 or 0, so that it is ensured that only the animation callback of the current synchronization cycle can be executed in the current synchronization cycle before the steps of the scheme are executed.
The current synchronization period may be one synchronization period that is being experienced at the current time.
The next synchronization period may be the next synchronization period after the current synchronization period. The next synchronization signal is the starting point of the next synchronization cycle, which is also the vsync signal.
In some embodiments, when it is determined that the execution times satisfy the preset condition, that is, when the execution times are less than the preset times, the terminal may directly obtain a time point corresponding to the completion of the current drawing interface, that is, a current interface drawing completion time.
It should be noted that, when the execution number is greater than or equal to the preset number, the steps of determining the current interface drawing completion time of the current synchronization cycle and determining the next synchronization signal arrival time of the next synchronization cycle do not need to be executed, and when the next synchronization cycle arrives after the current synchronization cycle elapses, the next synchronization cycle may be regarded as the current synchronization cycle, and the step of receiving the sliding operation for the display interface and acquiring the execution number of the animation callback in the current synchronization cycle is executed.
S303, in the current synchronization period, acquiring a first working duration corresponding to the animation callback of the current synchronization period, and acquiring a second working duration corresponding to the current interface drawing of the current synchronization period.
S304, calculating the sum of the first working time length and the second working time length, and determining the idle time between the drawing completion time of the current interface and the arrival time of the next synchronization signal based on the total time length of the current synchronization period and the sum.
S303 and S304 are explained below.
It is understood that the first operation duration may be a duration for which the terminal completes the animation callback of the current synchronization period. The second working duration may be a duration for completing the current interface drawing of the current synchronization period.
The total duration of the current synchronization period may be an intra-period duration corresponding to the current synchronization period. For example, when the screen refresh rate is 60Hz, the duration of one synchronization period is about 16 ms.
The idle time may be a time period within the current synchronization period during which no task (animation loop and UI drawing) is required to be performed.
In some embodiments, the terminal should perform an animation callback of the current synchronization period during the current synchronization period, and should perform the current interface drawing of the current synchronization period after the animation callback of the current synchronization period is completed. Furthermore, a first working time length corresponding to an animation callback for executing the current synchronization cycle and a second working time length corresponding to the current interface drawing of the current synchronization cycle can be obtained, because the animation callback is executed only once in the current synchronization cycle, the animation callback of the current synchronization cycle usually starts to be executed when the current synchronization signal of the current synchronization cycle arrives, the sum of the first working time length and the second working time length can be calculated, and naturally, the time period corresponding to the total time length of the current synchronization cycle can be subtracted from the time period corresponding to the total time length of the current synchronization cycle, the time period starting from the starting point in the current synchronization cycle corresponding to the sum, so that the idle time period in the current synchronization cycle, namely the idle time between the drawing completion time of the current interface and the arrival time of the next synchronization signal, can be obtained.
S305, starting to execute the animation callback of the next synchronization cycle in the idle time, and starting to execute the interface drawing of the next synchronization cycle after the animation callback is completed.
In some embodiments, in the idle time of the current synchronization cycle, the execution of the animation callback of the next synchronization cycle may be started, that is, the animation callback of the next synchronization cycle is advanced to the idle time of the current synchronization cycle and is started, and further, after the animation callback of the next synchronization cycle is completed and is still in the idle time of the current synchronization cycle, the execution of the interface drawing of the next synchronization cycle may be started, that is, the interface drawing of the next synchronization cycle may be advanced to the idle time of the current synchronization cycle and is executed. For example, the schematic diagram of the picture drawing shown in fig. 4 can be referred to. In fig. 4, a solid line box between sync signal 1 and sync signal 3 represents animation callback and interface rendering for the current sync period, a dotted line box represents animation callback and interface rendering for the next sync period, animation callback and interface rendering for the current sync period are performed, animation callback for the next sync period starts to be performed during idle time after animation callback for the current sync period is completed, and interface rendering for the next sync period starts to be performed after animation callback for the next sync period is completed.
And S306, determining the interface drawing completion time of the next synchronization period and determining the remaining idle time between the interface drawing completion time and the arrival time of the next synchronization signal in the idle time.
S307, if the duration of the remaining idle time is longer than the preset duration, starting to execute the animation callback of the adjacent synchronization cycle after the next synchronization cycle in the remaining idle time, and executing the interface drawing of the adjacent synchronization cycle after the animation callback of the adjacent synchronization cycle is executed.
S308, if the duration of the remaining idle time is less than or equal to a preset duration, in the next synchronization cycle, starting to execute an animation callback of an adjacent synchronization cycle after the next synchronization cycle, and executing interface drawing of the adjacent synchronization cycle after the animation callback of the adjacent synchronization cycle is executed.
S306 to S308 are explained below.
In some embodiments, the interface drawing of the next synchronization cycle is started within the idle time of the current synchronization cycle, and after the interface drawing of the next synchronization cycle is completed, if the interface drawing is still within the idle time of the current synchronization cycle, the remaining idle time between the interface drawing completion time of the next synchronization cycle and the arrival time of the next synchronization signal may be determined according to the interface drawing completion time of the next synchronization cycle and the arrival time of the next synchronization signal. Further, on one hand, if it is determined that the duration of the remaining idle time is greater than the preset time (indicating that the remaining idle time is sufficient and the animation callback of the subsequent synchronization cycle can be executed in advance), the animation callback of the next synchronization cycle (i.e. the adjacent synchronization cycle) after the next synchronization cycle can be started to be executed in the remaining idle time, and after the animation callback of the adjacent synchronization cycle is executed, the interface drawing of the adjacent synchronization cycle can be started to be executed in the adjacent synchronization cycle regardless of the current synchronization cycle or the next synchronization cycle. For example, the schematic diagram of the picture drawing shown in fig. 5 can be referred to. In fig. 5, the solid line boxes between the sync signal 1 and the sync signal 3 represent the animation callbacks and interface renderings in the current sync period, the dotted line boxes represent the animation callbacks and interface renderings in the next sync period, the gray boxes represent the animation callbacks and interface renderings in the adjacent sync period, both the animation callbacks and interface renderings in the next sync period are completed in the idle time, and there is sufficient remaining idle time in the idle time in which the execution of the animation callbacks in the adjacent sync period can be started. By adopting the method, on the basis of sufficient time, the animation callback of two synchronization periods after the current synchronization period is selected to be executed in advance, so that the probability of finishing the timeout of the animation callback in the subsequent synchronization period can be further reduced, and the probability of frame dropping caused by the timeout of the animation callback can be further reduced.
On the other hand, if it is determined that the duration of the remaining idle time is less than or equal to the preset duration (indicating that the remaining idle time is insufficient and it is not necessary to perform an animation callback of a subsequent synchronization cycle in advance), the animation callback of another synchronization cycle (i.e., an adjacent synchronization cycle) after the next synchronization cycle may be performed in the next synchronization cycle in advance, and the interface drawing of the adjacent synchronization cycle is performed after the animation callback of the adjacent synchronization cycle is performed. In this case, the animation callback of the adjacent synchronization cycle is executed in the next synchronization cycle, and when the time can enter the next synchronization cycle, the scheme is executed with reference to the steps S301 to S307, where the next synchronization cycle is the current synchronization cycle in the above steps, and the adjacent synchronization cycle is the adjacent synchronization cycle in the above steps. For example, the schematic diagram of the drawing of the picture shown in fig. 6 can be referred to. In fig. 6, a solid line frame between the sync signal 1 and the sync signal 3 represents animation callbacks and interface renderings in the current sync period, a dotted line frame represents animation callbacks and interface renderings in the next sync period, a gray frame represents animation callbacks and interface renderings in the adjacent sync period, both the animation callbacks and the interface renderings in the next sync period are completed within the idle time of the current sync period, and at this time, the remaining idle time is insufficient, and the animation callbacks in the adjacent sync period can not be executed in advance any more, and the animation callbacks in the adjacent sync period can be executed in the next sync period. By adopting the method, the animation callback of the next synchronization period is ensured to be executed in advance on the basis of insufficient time, the probability of finishing the overtime drawing of the interface caused by too long time spent on the animation callback can be reduced, the probability of the overtime refreshing of the application can be further reduced, the probability of frame dropping can be further reduced, and the probability of the pause caused by the frame dropping can be further reduced.
And S309, starting to execute the animation callback of the next synchronization cycle in the idle time, finishing the animation callback of the next synchronization cycle in the idle time, and starting to execute the interface drawing of the next synchronization cycle in the next synchronization cycle and when the next synchronization signal of the next synchronization cycle arrives.
In some embodiments, in the idle time of the current synchronization cycle, the animation callback of the next synchronization cycle may be started to be executed, that is, the animation callback of the next synchronization cycle is advanced to the idle time of the current synchronization cycle to be executed, and further, after the animation callback of the next synchronization cycle is completed, the next synchronization cycle is still in the idle time of the current synchronization cycle, the terminal may not execute any animation callback or interface drawing of any synchronization cycle until the next synchronization cycle is entered, and when a next synchronization signal of the next synchronization cycle arrives, the interface drawing of the next synchronization cycle is started to be executed again.
Optionally, in another embodiment, during the idle time of the current synchronization cycle, the execution of the animation callback of the next synchronization cycle may be started, that is, the animation callback of the next synchronization cycle is advanced to the idle time of the current synchronization cycle and is started. Further, after the animation callback of the next synchronization cycle is completed, the terminal is still in the idle time of the current synchronization cycle, and the terminal can start to execute the animation callback of the next synchronization cycle after the next synchronization cycle, that is, the animation callback of the next synchronization cycle after the next synchronization cycle is advanced to the idle time of the current synchronization cycle to start to execute until the next synchronization cycle is entered, and when the next synchronization signal of the next synchronization cycle arrives, the terminal starts to execute the interface drawing of the next synchronization cycle. By adopting the method, the animation callback of two synchronization periods after the current synchronization period is selected to be executed in advance, the probability of finishing the overtime of the interface drawing caused by too long time consumption of the animation callback can be further reduced, and the problem of frame drop caused by the overtime of the interface drawing can be further reduced.
And S310, starting to execute the animation callback of the next synchronization cycle in the idle time, and starting to execute the interface drawing of the next synchronization cycle in the next synchronization cycle and after the animation callback of the next synchronization cycle is finished.
In some embodiments, during the idle time of the current sync cycle, the execution of the animation callback of the next sync cycle may begin, i.e., the animation callback of the next sync cycle is advanced to begin execution within the idle time of the current sync cycle. Furthermore, after the animation callback of the next synchronization cycle is completed, the next synchronization cycle is already in the next synchronization cycle, and the interface drawing of the next synchronization cycle can be executed. For example, the schematic diagram of the picture drawing shown in fig. 7 can be referred to. In fig. 7, the solid line box between sync signal 1 and sync signal 3 represents the animation callback and interface drawing of the current sync cycle, the dashed line box represents the animation callback and interface drawing of the next sync cycle, the animation callback of the next sync cycle starts to be executed in the idle time of the current sync cycle, and the animation callback of the next sync cycle can be executed after the animation callback of the next sync cycle is completed and is in the next sync cycle. By adopting the method, the animation callback of the next synchronization period is executed in advance in the current synchronization period, so that the probability of finishing the overtime drawing of the interface due to too long time consumption of the animation callback can be reduced, the probability of frame dropping caused by the overtime drawing of the interface can be further reduced, and the probability of pause caused by the frame dropping can be further reduced.
According to the embodiment of the application, when the sliding operation aiming at the display interface is received, the execution times of the animation callback in the current synchronization period are obtained, the scheme can be executed under the condition that terminal resources are saved, then under the condition that the execution times are determined to be smaller than the preset times, the animation callback of the next synchronization period is executed in advance to the idle time of the current synchronization period, then the interface drawing of the next synchronization period is executed after the animation callback of the next synchronization period is completed, on the basis that the terminal memory is not influenced, the probability that the interface drawing is overtime due to too long time consumed by the animation callback can be reduced, the probability of application refresh overtime can be reduced, the probability of frame dropping can be reduced, and the probability of blocking caused by the frame dropping can be reduced. In addition, the execution time of the animation callback is advanced, the adjustment of the frequency of the processor is not involved, the problem of unsmooth jam is solved by improving the frequency of the processor in the related technology, the power consumption of the terminal is increased by improving the frequency of the processor, and the power consumption of the terminal is not influenced. In addition, the execution time of the animation callback is advanced, the animation callback of the next synchronization period can be executed in advance in the current synchronization period, the animation callback of the next synchronization period and the interface drawing can be executed in advance in the current synchronization period, even the animation callback of the next synchronization period and the animation callback of the next synchronization period can be executed in the current synchronization period, the probability of finishing the overtime of the interface drawing due to too long time of the animation callback can be further reduced, and the problem of frame drop caused by the overtime of the interface drawing can be further reduced.
