Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described by means of implementation examples with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Fig. 1 is a flowchart of an Android animation execution method provided in an embodiment of the present invention, where the embodiment is applicable to a case where a target value is dynamically changed in a first animation execution process, and the method may be implemented by a terminal, and in particular may be implemented by software and/or hardware in the terminal.
Referring to fig. 1, the Android animation execution method is applied to a first animation execution process, and comprises the following steps:
s110, receiving a target value change message, defining an end value of the second animation according to the target value change message, defining a start value of the second animation according to the end value of the first animation, and setting an opening value of the second animation according to the start value of the second animation, wherein the opening value of the second animation is smaller than the start value of the second animation.
The first animation and the second animation can be understood as any animation of changing the control value drawn by the Android terminal through codes, for example, the first animation can be a progress animation, and the progress animation can be understood as an animation of changing progress bar control information. The first animation type and the second animation type are the same, and can be all preset value animation valueanimation types; the value animation ValueAnimator type can be specifically defined by the following method:
Public class ValueAnimator{}；
the ValueAnimator class is Public common type, so that other classes have the access right of the value animation class. The class name of the value animation class is valueanimation, and the class name of the value animation class can be changed according to the requirements of research personnel, and is not limited herein.
Before constructing the animation, two global variables are defined by calling a numerical definition method respectively to represent a start value and an end value of the animation, and the animation is constructed according to the defined start value and end value. For example, a numerical definition method may be called to define two global variables respectively, to represent a start value and an end value of an animation, and may be specifically defined by the following method:
Private int startValue＝0；
Private int endValue＝80；
wherein startValue represents a start value of the animation, endValue represents an end value of the animation, and the start value and the end value are solved into private integer type values.
Wherein, when the executed animation is composed of one sub-animation, then the ending value of the sub-animation can be understood as the target value of the executed animation; when the performed animation is formed by joining a plurality of sub-animations, the end value of the last performed sub-animation can be understood as the target value of the performed animation. For example, if the performed animation is composed of one 0% to 50% of the progress animation, the end value 50 of the 0% to 50% of the progress animation may be understood as a target value of the performed animation; if the performed animation is an animation in which 0% to 50% of the progressive animation is joined with 30% to 80% of the progressive animation, the end value 80 of the later-performed 30% to 80% of the progressive animation can be understood as a target value of the performed animation.
In the execution process of the first animation, if a target value change message issued by the server is received, a new second animation needs to be constructed, and the execution process of the second animation and the first animation is linked, so that a complete and smooth execution animation with the target value changed is generated. Before constructing the second animation, defining a start value and an end value of the second animation, and defining the changed target value in the target value change message as the end value of the second animation; and defining a starting value of the second animation according to the ending value of the first animation, wherein the starting value of the second animation is smaller than or equal to the ending value of the first animation, namely, a part of the animation which is synchronously executed exists between the first animation and the second animation, so that the connection between the first animation and the second animation is smoother, and the two animations cannot be visually perceived to be executed, thereby giving people smoother animation watching experience.
The starting value of the second animation is set to be smaller than the starting value of the second animation, so that a certain time length is reserved for starting the second animation. Therefore, after the second animation is started according to the starting value of the second animation, the second animation can be accurately synchronized with the first animation, so that the connection precision of the first animation and the second animation is improved, and the smoothness of the animation is ensured.
Optionally, defining the end value of the second animation according to the target value modification message, and defining the start value of the second animation according to the end value of the first animation includes:
determining a changed target value according to the target change message, and calling a numerical definition method to define that the ending value of the second animation is equal to the changed target value; and subtracting a preset value from the predefined ending value of the first animation, and calling a value definition method to define a value of which the starting value of the second animation is equal to the ending value of the first animation minus the preset value.
The target value after modification may be analyzed from the target modification message sent by the server, specifically, the identifier of the target value in the target modification message may be identified, and the value corresponding to the target value identifier may be obtained. Wherein the changed target value may be assigned to an end value of the second animation. The end value of the first animation is a predefined value before the first animation is constructed. The preset value is more than or equal to 0 and is smaller than the ending value of the first animation; when the preset value is 0, the ending value of the first animation is set as the starting value of the second animation, so that the second animation and the first animation are executed at the same time at the ending value position of the first animation, and the aim of connecting the first animation and the second animation is fulfilled. Preferably, the preset value may be set according to an end value of the first animation, for example, the preset value may be an integer value of a preset proportion of the end value of the first animation, and specifically may be an integer value of 5% or 10% of the end value of the first animation. For example, when the end of the first animation is 50, the preset ratio is 5%, 50×5% =2.5, and 3 is obtained after rounding, and 3 is taken as the preset value. The preset proportion can be set according to specific requirements of research personnel, and is not particularly limited herein.
The method comprises the steps of defining a value obtained by subtracting a preset value from an ending value of a first animation as a starting value of a second animation, and ensuring that the starting value of the second animation is smaller than or equal to the ending value of the first animation, so that part of the animations which are synchronously executed exist between the first animation and the second animation, the connection between the first animation and the second animation is smoother, and the two animations cannot be visually perceived to be executed, thereby giving people smoother animation watching experience.
Optionally, setting the start value of the second animation according to the start value of the second animation includes:
subtracting the starting time consumption value of the second animation from the starting value of the second animation, and setting the difference value between the starting value of the second animation and the starting time consumption value of the second animation as the starting value of the second animation.
The starting time of the second animation can be an animation starting time experience value set by a research and development personnel, can be a starting time of the first animation, and can be an average time of historical animation starting time recorded in the Android terminal before the second animation is started.
The starting time consumption value of the second animation can be understood as a whole integer multiple of a time interval between each executing animation value of the first animation corresponding to the starting time consumption of the second animation. For example, when the first animation is a 0% to 50% progress animation and the execution period is 2000ms, 1, 2, 3 … 49, 50 may be understood as the execution animation values of the first animation, and the time intervals between the execution animation values of the first animations 0 to 1,1 to 2..49 to 50 are the same, which are t=2000 ms/50=40 ms. At this time, if the starting time of the second animation is 80ms, the starting time value of the second animation is 80/40=2; if the starting time of the second animation is 100ms, the starting time value of the second animation is 100/40=2.5, the starting time value is 3 after taking the integer, and the starting time value is 3.
The difference obtained by subtracting the starting consumption value of the second animation from the starting value of the second animation can be set as the starting value of the second animation, so that the starting value of the second animation is smaller than the starting value of the second animation, and a certain time period is reserved for starting the second animation. Therefore, after the second animation is started according to the starting value of the second animation, the second animation can be accurately synchronized with the first animation, so that the connection precision of the first animation and the second animation is improved, and the smoothness of the animation is ensured.
S120, calling an animation construction method, and constructing the second animation according to the starting value of the second animation and the ending value of the second animation.
The method for constructing the second animation is called, and the second animation is constructed according to the starting value of the second animation and the ending value of the second animation, specifically, the method can be implemented as follows:
ValueAnimator mValueAnimator2＝ValueAnimator.ofInt(startValue2,endValue2)；
wherein startValue2 represents a start value of the second animation, and endValue2 represents an end value of the second animation; the type of the second animation is a value animation type; wherein, the executing animation value of the second animation is defined as an Int integer type, that is, the executing animation values are all positive integers; the name of the second animation is mValueAnimator2, and the name of the second animation can be changed according to the requirements of the research personnel, which is not limited herein.
Wherein, after the second animation construction is completed, the execution period of the second animation can be set; wherein, the execution period refers to the time required by the animation to execute the whole process from the starting value to the ending value; the setting method of the execution period can be called to set the second animation execution period, and specifically, the setting method can be set by the following method:
mValueAnimator2.setDuration(xxx)；
where xxx identifies the execution period duration in milliseconds ms, which may be set to 500, 1000, 2000, etc.
Preferably, the execution period of the second animation may correspond to the preset execution period of the first animation, and it may also be understood that the time interval between the execution animation values of the second animation is the same as the time interval between the execution animation values of the first animation. The time interval between the executing animation values of the animation may be understood as an updating period of the executing animation values of the animation, that is, preferably, the updating period of the executing animation values of the second animation is the same as the updating period of the first animation values.
Illustratively, when the first animation is a 0% -80% progress animation, the execution period is 2000ms, the time interval between executing animation values is t1=2000 ms/80=25 ms, i.e. the update period of executing animation values of the first animation is 25ms. The time interval between the execution of the animation values of the second animation is preferably 25ms, i.e. the update period of the execution of the animation values of the second animation is the same as the update period of the first animation values. When the second animation is 60% -90% of the execution animations, then the execution period of the second animation is preferably t=t1× (90-60) =750 ms.
The time interval between the execution animation values of the first animation can be obtained through the execution period of the first animation, and the update period of the execution animation values of the first animation is determined. Therefore, the updating period of the executing animation value of the second animation is consistent with the updating period of the executing animation value of the first animation, so that the second animation and the first animation can be more accurately synchronized in the synchronous executing part, the overall smoothness of the connected animations is improved, and the user experience is improved. In addition, the starting consumption value of the second animation can be determined through the updating period of the executing animation value of the first animation, so that the starting value of the second animation can be confirmed, and the connection precision of the second animation and the first animation is improved.
S130, calling a first animation monitoring function to determine an execution animation value of the first animation, and calling an animation start method to start the second animation when the execution animation value is equal to the start value of the second animation.
The execution of the animation values is understood to be the integer number of steps of 1 between the start value and the end value of the first animation. For example, when the first animation is a progress animation of 0% to 30%, the execution animation value of the first animation may be 1, 2, 3..29, 30. The current executing animation value in the executing process of the first animation can be monitored by calling the first animation monitoring function. The second animation can be started when the current executing animation value is a second animation starting value, so that the second animation is accurately connected with the first animation after the second animation is started and time is consumed for starting the second animation.
The animation opening method may specifically be a mvauueanimator 2.Start () method, and the opening of the second animation mvauueanimator 2 may be achieved by calling the start method. And, when the animation listening function determines that the execution animation value of the first animation is equal to the animation end value, the animation execution may be ended.
Optionally, invoking the first animation listening function to determine an execution animation value of the first animation includes:
and in the first animation executing process, calling a callback monitoring method in the pre-added first animation monitoring function, and determining an executing animation value of the first animation.
The first animation monitoring function can be specifically added by the following method:
mValueAnimator.addUpdateListener(mUpdateListener)；
wherein, adding the monitoring function in the first animation can be realized by an addUpdateListener method; wherein the mUpdateListener object is a first animated listener object, i.e., a first animated listener function.
The specific method of the listener object mUpdateListener can be defined as follows:
wherein, the onAnimationUpdate represents a callback listening method in a listener object of the first animation. The callback monitoring method in the first animation monitoring function can monitor the current executing animation value of the first animation. Thus, the second animation can be controlled to be started when the execution animation value of the first animation is the starting value of the second animation.
Optionally, the callback monitoring method comprises parameter animation of a preset value animation type;
correspondingly, calling a callback monitoring method in the pre-added first animation monitoring function to determine an execution animation value of the first animation, wherein the method comprises the following steps:
and calling a getAnimatedValue () method in a callback monitoring method in the pre-added first animation monitoring function to acquire a current attribute value of the parameter animation, and determining the current attribute value as an execution animation value of the first animation.
The callback monitoring method onAnimationUpdate includes an animation parameter animation of a Value animation type, and a current attribute Value of the animation parameter animation can be determined as an execution animation Value of the first animation.
The obtaining of the current attribute value of the parameter animation can be realized by the following steps:
int animatorValue＝(int)animation.getAnimatedValue()；
the method comprises the steps of obtaining a current attribute value of animation through a getanimation value method, assigning the current attribute value to a defined integer value, and representing the value as an executing animation value of a first animation. The starting time of the second animation can be controlled by acquiring the executing animation value of the first animation, so that the second animation can be accurately connected with the first animation after the second animation is started.
Optionally, after the first animation monitoring function is called to determine the execution animation value of the first animation, the method further comprises: and updating the control information according to the execution animation value of the first animation.
After the callback listening method onammonification update acquires the execution animation value animatorvue of the first animation, the spatial information may be updated according to the execution animation value. When the control is a progress bar space, the control information is the progress information of the progress bar, and the progress information of the progress bar is updated by the following method:
progressBar.setProgress(animatorValue)；
the progress bar is an example object of the progress bar, and the progress information can be updated according to the execution animation value animate value by calling the setProgress method.
Optionally, before receiving the target value change message, the method further includes:
defining a value animation type, calling an animation construction method, and constructing a first animation of the value animation type according to a predefined starting value of the first animation and an ending value of the first animation; and calling an animation starting method to start the first animation.
The method comprises the steps of setting a first animation according to a starting value and an ending value of the first animation, and calling an animation construction method to construct the first animation, wherein the constructed first animation type can be a value animation type; after the first animation is built, an execution period setting function can be called to set the execution period of the first animation; wherein, the animation open method can be called to open the first animation, thereby ensuring that the first animation starts to execute. And in the execution process of the first animation, the execution method of the Android animation can be realized after the target value is changed. The functions or methods used in the first animation construction method, the execution cycle setting method, the starting method, and the like can refer to the second animation to realize functions or methods with the same functions, i.e., the first animation and the second animation can use the same method to realize the operation with the same purpose.
According to the Android animation execution method, in the first animation execution process, after the target value change message issued by the server is received, the second animation is constructed immediately according to the issued target value change message, so that the execution period duration of the second animation is reduced; the starting value of the second animation is set, and the second animation is started when the executing animation value of the first animation is the starting value of the second animation, instead of starting the second animation after the execution of the first animation is finished, so that the connection between the first animation and the second animation is smoother, the animation target value is dynamically changed in the animation executing process, the animation executing is smoother, and the user experience is improved.
