本文详细解释了在动画处理中遇到的视图可见性改变和触摸事件丢失的问题，提供了两种解决方案：将`animation.setFillAfter(true)`更改为`false`或在动画的View外部嵌套一个View。此问题源于动画期间视图被位图替换，导致后续操作无法正确作用于实际视图。

前提是你的Animation设置了这样一个属性：

final Animation animation；animation.setFillAfter(true);

原因：

All the animations (before android 3.0) are actually applied to a bitmap which is a snapshot of your view instead of on your original view. When you are setting the fill after to true this actually means that the bitmap will continue to be displayed on the screen instead of your view. This is the reason why the visibility won't change upon using setVisibility and also the reason why your view will not be receiving touch events in its new (rotated) bounds.

解决方案：

1、将setFillAfter设置为false，或者不设置（默认是false）

2、在你要做动画的View外部嵌套一个View
