运行在视频查看Android的奥飞动漫 [英] Run alpha animation on Video View android

问题描述

我已经成功添加VideoView在我的布局，我能够发挥它。我对videoview之上，点击某个按钮时，一个漂亮的动画标志。在同一时间，我想淡出视频。但在其上运行奥飞动漫immedietly把它变黑。我发现videoview没有表现得像一个普通的观点，因为它的表面观。我试图把它的框架布局里面，但没有奏效。动画看起来是这样的：

I've successfully added VideoView on my layout and I'm able to play it too. I have a nice animating logo on top of videoview, when certain button is clicked. In the same time I want to fade out the video. But running alpha animation on it immedietly turn it black. I found that videoview is not behaving like an ordinary view, because it's surface view. I tried putting it inside frame layout, but it didn't work. Animation looks like this:

AlphaAnimation alphaAnimation = new AlphaAnimation(1.0f, 0.0f);
alphaAnimation.setDuration(1000);
alphaAnimation.setFillAfter(true);

videoView.suspend(); //pause video
videoView.startAnimation(alphaAnimation);

所以，我怎么能淡出视频？

So how can I fade out video?
