我想有一个查看最初是不可见的，当我preSS一个按钮，就变得可见，在动画褪色。我使用了 AlphaAnimation 的褪色效果。问题是，如果我做的观点看不到动画都看不出来。

I want to have a View that initially is invisible and when I press a button, it becomes visible with a fade in animation. I'm using the AlphaAnimation for the fading effect. The problem is that if I make the view invisible the animation can't be seen.

推荐答案

提供一个 AnimationListener 的动画，使视图可见只要动画开始。

Provide an AnimationListener to the Animation and make the View visible as soon as the Animation starts.
