直接上代码:

java代码:

LayoutInflater inflater = LayoutInflater

               .from(TeiHimeActivity.this);
       final View layout = inflater.inflate(R.layout.dialog_videoview,
               null);
       VideoView mVideoView = (VideoView) layout
               .findViewById(R.id.sh_myvideoview);
       mVideoView.setZOrderOnTop(true);
       mVideoView.setVideoPath("/mnt/sdcard/daomeixiong.mp4");
       //
       final WindowManager wm = (WindowManager) getApplicationContext()
               .getSystemService("window");
       //
       int width = wm.getDefaultDisplay().getWidth();
       int height = wm.getDefaultDisplay().getHeight();
       mVideoView.start();

       WindowManager.LayoutParams wmParams = new WindowManager.LayoutParams();
       wmParams.type = 2002; // 2002表示系统级窗口
       wmParams.format = 1;

       wmParams.flags = 40;
       wmParams.width = width;
       wmParams.height = height;
       wm.addView(layout, wmParams);// 创建View

       // 播放出错回调
       mVideoView.setOnErrorListener(new OnErrorListener() {
           @Override
           public boolean onError(MediaPlayer mp, int what, int extra) {
               wm.removeView(layout);
               return false;
           }
       });

       // 播放完成回调
       mVideoView.setOnCompletionListener(new OnCompletionListener() {
           @Override
           public void onCompletion(MediaPlayer mp) {
               wm.removeView(layout);
           }

});

布局文件R.layout.dialog_videoview

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@android:color/white" >
    <VideoView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:id="@+id/sh_myvideoview"
         />
</RelativeLayout>

谢谢观赏~
