Set animation listener to Activity animations
提问by akc
I am using overridePendingTransitionmethod to perform custom Activity animations.
我正在使用overridePendingTransition方法来执行自定义活动动画。
I would like to know when the animation ends ( a callback/listener ).
我想知道动画何时结束（回调/侦听器）。
Is there any direct way of achieving this, if not please suggest me some work around.
有没有直接的方法可以实现这一点，如果没有，请建议我一些解决方法。

overridePendingTransitiondoes not have a listener. Like I wrote an earlier post you rather wanna use a normal animation instead for the overridePendingTransition(that is just for Android 2.0 and above).
overridePendingTransition没有听众。就像我之前写的一篇文章，你宁愿使用普通动画来代替overridePendingTransition（仅适用于 Android 2.0 及更高版本）。
You can get a similiar effect and you can also do more cool stuff with an ordinary animation. My earlier post here: Load XML slowly
你可以得到类似的效果，你也可以用普通的动画做更多很酷的东西。我之前的帖子：缓慢加载 XML

I use this method to start any animation (resID of the animation XML). If nextPuzzleOnEnd is true, the method "nextPuzzle" is called when the animation has finished.
我使用此方法启动任何动画（动画 XML 的 resID）。如果 nextPuzzleOnEnd 为真，则在动画完成时调用方法“nextPuzzle”。
The method is part of my puzzle-apps and I use it to display any success animation and afterwards (after anim has finished) continue with the next puzzle.
该方法是我的拼图应用程序的一部分，我用它来显示任何成功动画，然后（动画完成后）继续下一个拼图。
/*
* start animation (any view)
*/
private void startAnimation(View v, int resId, Boolean nextPuzzleOnEnd){
Animation anim;
if(v!=null){ // can be null, after change of orientation
anim = AnimationUtils.loadAnimation(this.getContext(),resId);
anim.setFillAfter(false);
v.setAnimation(anim);
if( nextPuzzleOnEnd ){
anim.setAnimationListener(new AnimationListener() {
public void onAnimationStart(Animation anim)
{
};
public void onAnimationRepeat(Animation anim)
{
};
public void onAnimationEnd(Animation anim)
{
nextPuzzle();
};
});
}
v.startAnimation(anim);
}
}

After unsuccessfully browsing Google for this question, I've found a solution by going through all override-methods.
在为这个问题浏览谷歌失败后，我通过所有的覆盖方法找到了一个解决方案。
So what I did, was overriding this method in the activity that is entering the screen:
所以我所做的是在进入屏幕的活动中覆盖这个方法：
Requires API level 21
需要 API 级别 21
@Override
public void onEnterAnimationComplete() {
super.onEnterAnimationComplete();
}

@Hambug solution is nice. But there is problem. onEnterAnimationComplete will work on Lollipop and above API (21).
@Hambug 解决方案很好。但是有问题。onEnterAnimationComplete 将适用于 Lollipop 及以上 API (21)。
@Override
public void onEnterAnimationComplete() {
super.onEnterAnimationComplete();
//write code here.
}
whatever code you write in above method, won't execute on prelolipop devices. So you should put a version check and write it according to you need e.g. in onCreate.
您在上述方法中编写的任何代码都不会在 prelolipop 设备上执行。因此，您应该进行版本检查并根据需要编写它，例如在 onCreate 中。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP){
//write code here.
}
