The computer readable storage medium has stored thereon a computer program which, when executed by a processor, can implement a method for measuring a response time of a terminal screen as in the embodiments of fig. 2 to 4 described below.
As shown in fig. 2, an embodiment of the present invention provides a method for measuring a response time of a terminal screen, including, but not limited to, the following steps:
s201, acquiring an interrupt receiving time point when the terminal control center receives the interrupt signal.
And the interrupt signal is a hardware signal sent to the terminal control center by the terminal screen after the terminal screen responds to the touch action.
S202, obtaining the time point of the completion of the terminal interface refreshing.
And the refreshed terminal interface is a new terminal interface redrawn by the terminal control center after responding to the interrupt signal.
S203, calculating the response time consumption of the terminal screen according to the interruption receiving time point and the completion time point.
In an embodiment of the present invention, the terminal screen is a touch screen.
Based on the above steps S201 to S203, in practical applications, the response of the terminal screen to the game or application is mainly divided into the following time stages:
stage one: the user makes a preset touch action on the capacitive surface of the terminal screen → the terminal screen performs signal processing → the terminal screen outputs an interrupt signal.
For the time consumed by the stage one, usually, a probe is placed on a single body on the surface of the touch screen, the touch screen is quickly clicked and tested, waveforms triggered by signals in the single body of the touch screen are compared, and the output time of an interrupt signal of a screen of a test terminal is compared, so that the average time delay can be calculated. Therefore, the time consumption of the first stage is related to the capability of the hardware, and the time consumption of the first stage is basically fixed after the hardware is fixed.
It can be understood that the response time of the terminal screen measured in the embodiment of the present invention does not include the fixed time consumption of the above-mentioned stage.
And a second stage: the terminal system receives and responds to the interrupt signal from the terminal screen, thereby activating the working state of the CPU.
And a third stage: inputting interrupt signal into interrupt controller → entering terminal screen drive → registering in the entry function of platform interrupt signal → executing work queue in terminal screen interrupt function → calling controller and terminal screen communication at I2C platform end → completing reporting of input event.
And a fourth stage: the application corresponding to the current foreground receives the report of the input event → performs corresponding logic processing (such as redrawing the current interface) → finishing the real output of the screen to the screen through surfefinger processing, thereby finishing the updating of the screen.
In the embodiment of the present invention, the time point of acquiring the interrupt signal at the terminal system in step S201 is to acquire the time point of receiving and responding the interrupt signal from the terminal screen by the terminal system, and the time point of acquiring the completion time point of the terminal interface refresh in step S202 is to acquire the time point of completing the update of the terminal screen, so that two important stages of the terminal screen response can be quickly located by using the interrupt signal and the relevant information of the terminal interface refresh as the object to be acquired, thereby calculating the time consumed by the terminal screen response.
According to the method for measuring the response time of the terminal screen, provided by the embodiment of the invention, after the terminal screen responds to the touch action, the terminal control center receives the interrupt receiving time point of the interrupt signal sent by the terminal screen and the terminal interface refreshing completion time point, and calculates the response time consumption of the terminal screen, wherein the interrupt signal sent by the terminal screen represents the fixed time consumption stage of the terminal screen response, the terminal control center receives the interrupt signal and responds to the first non-fixed time consumption stage representing the terminal screen response, and the terminal interface refreshing completion represents the completion of the last non-fixed time consumption stage of the terminal screen response. The method for measuring the response time of the terminal screen provided by the embodiment of the invention can replace the traditional mode of shooting and measuring by using a high-speed camera, reduces the test threshold, is beneficial to developing and testing the measurement project consuming time of the response of the terminal screen, and improves the development and test efficiency.
As shown in fig. 3, the embodiment of the present invention provides another terminal screen response time measuring method based on the terminal screen response time measuring method provided in fig. 2, including but not limited to the following steps:
s301, setting an interface refreshing button, and monitoring the touch action.
In step S301, the interface refresh button may be an application program installed in the terminal, and is called when the response time of the terminal screen needs to be measured, and is displayed on the terminal screen.
And if the interface refreshing button is called, starting to monitor the touch action, namely continuously detecting whether the user has the action of clicking the interface refreshing button, so as to judge whether a terminal screen response time measurement event is triggered or not and whether to start to execute the measurement of the time consumed by the terminal screen response.
S302, when the touch action triggers the interface refreshing button, triggering a terminal screen response time measuring event so that the terminal screen sends the interrupt signal to the terminal control center.
And the interrupt signal is used for enabling the terminal control center to redraw a new terminal interface.
In step S302, after triggering the terminal screen response time measurement event, the terminal screen sends an interrupt signal to the terminal control center, and the terminal control center responds based on the interrupt signal after receiving the interrupt signal, that is, refreshes the current terminal interface. And the refreshing process of the current terminal interface is the process of redrawing a new terminal interface.
In a specific application, after the step S301 and the step S302 are the aforementioned stage one of the terminal screen response and the terminal screen response time measurement event is triggered, the terminal control center responds based on the interrupt signal, i.e., the aforementioned stage two of the terminal screen response.
In an embodiment, after the step S302, the method may further include:
s3021, acquiring a trigger time point of the touch action trigger interface refreshing button;
and S3022, acquiring the hardware signal received by the terminal control center after the trigger time point, and acquiring a receiving time record of the hardware signal received by the terminal control center.
S3023, acquiring the interrupt signal in the hardware signal through Systrace, and receiving the receiving time record of the interrupt signal by the terminal control center.
The acquiring actions in the above steps S3021 to S3023 are all acquiring information from the terminal control center or the terminal screen, and through the above steps S3021 to S3023, all the interrupt signals received by the terminal control center after the touch action of the user triggers the interface refresh button, and the receiving time record generated by the terminal control center receiving the interrupt signals can be collected.
The terminal control center receives various hardware signals and is used for informing the terminal control center to execute different tasks, such as startup and shutdown, sound adjustment, data transmission and the like.
In the embodiment of the present invention, by systrace, only the function of outputting and acquiring the interrupt signal can be turned on, such as: starting a child thread by reading the following system file: "/d/tracing/trace _ pipe", so as to obtain the interrupt signal recorded by sysstrace and the corresponding time point after the touch action triggers the interface refresh button.
In practical application, sysstrace is a self-contained system analysis tool in an Android system, and functions of the sysstrace include tracking of I/O operations of the system, kernel work queues, CPU loads, running conditions of subsystems of the Android and the like. The principle is roughly as follows: some information labels are inserted into some key links (such as System Service, virtual machine, Binder drive, etc.) of the System, the execution time of a certain core process is determined by the start and the end of the Label, and then the Label is collected to obtain the operation time information of the key path of the System, thereby obtaining the operation performance information of the whole System.
S303, acquiring an interrupt receiving time point when the terminal control center receives the interrupt signal.
According to the steps S301, S302, and S3021 to S3023, one implementation manner of the step S303 may be:
and analyzing the interrupt receiving time point of the interrupt signal according to the receiving time record and the triggering time point of the interrupt signal.
After acquiring the interrupt signal after the trigger time point and the receiving time record of the interrupt signal, the interrupt signal closest to the time point of the user trigger interface refresh button can be found out, where the interrupt signal is the hardware signal received by the terminal control center, and the interrupt receiving time point of the interrupt signal is the time point of the terminal control center responding to the terminal signal, that is, the start time point of the terminal screen response stage two described above.
And S304, acquiring the time point for finishing the refreshing of the terminal interface.
In the above step S303 and step S304, the time point when the terminal interface is refreshed and the time point when the terminal control center receives the interrupt signal, that is, the time points of the second stage and the fourth stage of the terminal response, are obtained, so that the total time consumption of the terminal screen response, that is, the time consumption of the terminal screen response in the following step S305, can be obtained from the time point when the terminal control center receives the interrupt signal to the time point when the terminal interface is refreshed.
In one embodiment, one implementation manner of the step S304 may be;
s3041, calling a SurfaceFlinger to output a drawing completion time point of each frame of terminal interface after replacement;
s3042, arranging the drawing completion time points according to the sequence of the frame numbers;
s3043, the drawing completion time point of the last frame is used as the completion time point of the terminal interface alternation.

if the difference between the drawing time of the ith frame terminal interface and the standard drawing time is within the error range, drawing the ith frame terminal interface normally;
and if the difference between the drawing time of the ith frame terminal interface and the standard drawing time is out of the error range, drawing the ith frame terminal interface abnormally.
In a specific application, the drawing time of the terminal interface of the ith frame can be obtained through sysstrace, and it can be understood that when the time consumption of other response phases needs to be detected, the time consumption of the corresponding response phase can also be obtained through the sysstrace, so that the abnormal point can be quickly located.
In specific application, when the drawing of the ith frame terminal interface is detected to be abnormal, a mark is added to the ith frame terminal interface, so that a technician can repair the ith frame terminal interface conveniently.
S305, calculating the response time consumption of the terminal screen according to the interrupt receiving time point and the completion time point.
As shown in fig. 4, the embodiment of the present invention provides an actual application diagram of the terminal screen response time measurement shown in fig. 3, so as to describe the application process of the above step S301 to step S305.

As shown in fig. 5, an embodiment of the present invention further provides a terminal screen response time measuring apparatus 50, including:
an interrupt receiving time point obtaining module 51, configured to obtain an interrupt receiving time point when the terminal control center receives the interrupt signal.
The interrupt signal is a hardware signal sent to the terminal control center by the terminal screen after the terminal screen responds to the touch action;
and a completion time point obtaining module 52, configured to obtain a completion time point of the terminal interface refresh.
The refreshed terminal interface is a new terminal interface redrawn by the terminal control center after responding to the interrupt signal;
and a terminal screen response time measuring module 53, configured to calculate a terminal screen response time according to the interrupt receiving time point and the completion time point.
The terminal control center receives various hardware signals and is used for informing the terminal control center to execute different tasks, such as startup and shutdown, sound adjustment, data transmission and the like.
In a specific application, by systrace, only the function of outputting and acquiring the interrupt signal can be started, such as: starting a child thread by reading the following system file: "/d/tracing/trace _ pipe", so as to obtain the interrupt signal recorded by sysstrace and the corresponding time point after the touch action triggers the interface refresh button.
In a specific application, the drawing completion time point of each frame of the terminal interface in the terminal interface refreshing process can be output by calling the surfeFinger, wherein when the drawing of the terminal interface of the last frame is completed, the drawing completion time point is not updated, and therefore, the drawing completion time point of the last frame can be used as the alternate completion time point of the terminal interface.
In the embodiment of the present invention, the time point when the terminal interface is refreshed and the time point when the terminal control center receives the interrupt signal are obtained, that is, the time points of the second stage and the fourth stage of the terminal response are obtained, so that the total time consumption of the terminal screen response, that is, the time consumption of the terminal screen response in the terminal screen response time measurement module, can be obtained from the time point when the terminal control center receives the interrupt signal to the time point when the terminal interface is refreshed.
The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the foregoing embodiments illustrate the present invention in detail, those of ordinary skill in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the spirit and scope of the embodiments of the present invention, and are intended to be included within the scope of the present invention.
