如果想简单的播放视频文件，用上面的代码就可以了，我要说的是在使用过程中遇到的问题！

1、当布局文件中的SurfaceView和VideoView这两个控件的顺序颠倒以后就会出现看不到视频的问题，或者将SurfaceView设置为不可见。如果你先用了VideoView 然后又要用SurfaceView ，那么只要将VideoView隐藏就可以了，否则在SurfaceView上画的东西是看不到的。

2、 Uri.parse("android.resource://" + getPackageName() + "/" +R.raw.movie);//只能获得res下的文件。如果哪位大侠知道如何获得assets的Uri 请留言谢谢。
