PopupWindow animation not working

I has a nice PopupWindow which I want to appear with an animation. I do it like this:

popup.setAnimationStyle(R.anim.appear);
popup.showAtLocation(popupMenuLayout, gravity, offsetX, offsetY);

I then set up a listener for changing the animation:

popup.setOnDismissListener(new PopupWindow.OnDismissListener(){
 @Override
 public void onDismiss(){
  popup.setAnimationStyle(R.anim.disappear);
 }      
});

But, hey, it won't work. Neither for res/anim/appear:

<translate xmlns:android="http://schemas.android.com/apk/res/android"
 android:fromYDelta="100%"
 android:toYDelta="0"
 android:duration="1000" 
/>

Nor for res/anim/disappear:

<translate xmlns:android="http://schemas.android.com/apk/res/android"
 android:fromYDelta="0"
 android:toYDelta="100%"
 android:duration="1000"
/>

Any clues?

Actually, PopupWindow.setAnimationStyle expects a style with 2 entries. You'll need to have two xmls, each containing a <set>, one for showing and the other for hiding the window. When this is done, put the following piece into values/styles.xml:

<style name="AnimationPopup">
    <item name="android:windowEnterAnimation">@anim/popup_show</item>
    <item name="android:windowExitAnimation">@anim/popup_hide</item>
</style>

and set your animation style to R.style.AnimationPopup. That'll do.

I've got this information from https://github.com/lorensiuswlt/NewQuickAction3D the documentation didn't seem to mention it.

Update:

An update to Android SDK in 2012 have changed XML syntax. The original @android:windowEnterAnimation now became android:windowEnterAnimation. So this answer is updated accordingly.
