在 WindowManager 上添加动画视图
我有一个视图（customView）添加到 WindowManager 中。
WindowManager mWm = (WindowManager)activity.getApplicationContext().getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams(WindowManager.LayoutParams.FILL_PARENT, 0, PixelFormat.TRANSPARENT);
mWl.dimAmount = 0.0f;
mWm.addView(customView, mWl);
在自定义视图中，按下关闭按钮时我将调用翻译动画。
//// 这是动画的处理程序 ////
final Handler translateHandler = new Handler();
final Runnable mtranslateUp = new Runnable() {
public void run() {
Log.v("TEST","mtranslateUp Runnable");
startAnimation(translateUp);
}
};
//// 这是关闭按钮的监听器 ////
View.OnClickListener closeButtonListener = new View.OnClickListener() {
public void onClick(View v) {
translateHandler.post(mtranslateUp);
}
};
//// 这是向上平移动画 ////
translateUp = new TranslateAnimation(0,0,0,-200);
translateUp.setFillAfter(true);
translateUp.setDuration(1000);
translateUp.setAnimationListener(new AnimationListener(){
@Override
public void onAnimationEnd(Animation animation) {
Log.v("TEST","translateUp onAnimationEnd");
}
@Override
public void onAnimationRepeat(Animation animation) {
}
@Override
public void onAnimationStart(Animation animation) {
Log.v("TEST","translateUp onAnimationStart");
}}
);
如果添加了 customView对于一项活动，这些代码工作正常！
当customView添加到WindowManager时，onAnimationStart中的Log不显示，但Runnable中的Log可以显示。
任何人都可以告诉如何在添加到 WindowManager 的视图上制作动画吗？
I have a view (customView) added to the WindowManager.
WindowManager mWm = (WindowManager)activity.getApplicationContext().getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams(WindowManager.LayoutParams.FILL_PARENT, 0, PixelFormat.TRANSPARENT);
mWl.dimAmount = 0.0f;
mWm.addView(customView, mWl);
Inside the custom view, I will call a translate animation when close button is pressed.
//// This is the handler for the animation ////
final Handler translateHandler = new Handler();
final Runnable mtranslateUp = new Runnable() {
public void run() {
Log.v("TEST","mtranslateUp Runnable");
startAnimation(translateUp);
}
};
//// This is the listener for the close button////
View.OnClickListener closeButtonListener = new View.OnClickListener() {
public void onClick(View v) {
translateHandler.post(mtranslateUp);
}
};
//// This is the translate up animation ////
translateUp = new TranslateAnimation(0,0,0,-200);
translateUp.setFillAfter(true);
translateUp.setDuration(1000);
translateUp.setAnimationListener(new AnimationListener(){
@Override
public void onAnimationEnd(Animation animation) {
Log.v("TEST","translateUp onAnimationEnd");
}
@Override
public void onAnimationRepeat(Animation animation) {
}
@Override
public void onAnimationStart(Animation animation) {
Log.v("TEST","translateUp onAnimationStart");
}}
);
If the customView is added to an activity, these code works fine!
When the customView is added to a WindowManager, the Log inside the onAnimationStart didn't show but the Log inside the Runnable can be shown.
Can anybody tells how to do animation on a view that is added to the WindowManager?

您应该为视图布局参数设置动画。例如我使用一种方法来更新视图布局：
显然mWindowService是context.getSystemService(Context.WINDOW_SERVICE)。
我在动画中触发这个方法：
You should animate the view LayoutParameters. For example I use a method to update the view layout:
Obviously mWindowService is context.getSystemService(Context.WINDOW_SERVICE).
I trigger this method in the animation:
我在附加到 WindowManager 的视图时遇到了类似的问题。尝试将 ViewGroup 添加到 WindoManager 而不是直接添加视图。它应该有效。
I was facing similar problem with a View attached to WindowManager.Try adding ViewGroup to WindoManager than View directly. It should work.
windowManager需要android系统的动画。所以自定义动画将不起作用windowManagerneed a animation by android system. so the custom animation will not work我有一个问题。
当我在 onAnimationUpdate 中使用 updateViewLayout 并设置 LayoutParams 的宽度时，动画丢帧。
但我设置了LayoutParams的x或y，动画就可以了。
就像下面的代码：
I had a problem.
When i use updateViewLayout in onAnimationUpdate, and i set the LayoutParams's width, the animation has dropped frames.
But i set the LayoutParams's x or y, the animation is ok.
like the below code:
