android如何播放assets中的视频文件

[qq_35778853]

public class VideoActivity extends ActionBarActivity {

private VideoView mVideoView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video);

MediaController mController = new MediaController(this);
mVideoView = (VideoView) findViewById(R.id.mVideoView);
mVideoView.setMediaController(mController);
mController.setMediaPlayer(mVideoView);
mVideoView.requestFocus();

//获取AssetManager对象
AssetManager am = getAssets();
// 打开指定文件,获取assets目录下指定文件的AssetFileDescriptor对象
AssetFileDescriptor afd = null;
try {
afd = am.openFd("");
//下面不知怎么写了，求助
} catch (IOException e) {
e.printStackTrace();
}

}
}

videoView.start();

[网络咖啡]

videoView = (VideoView)findViewById(R.id.videoView); //设置视频路径 videoView.setVideoURI(Uri.parse(videoUrl)); //开始播放视频 videoView.start(); 使用VideoView可以直接播放assets里面的文件的

如果是指定视频 则可以直接写绝对路径file:///android_asset/文件名，然后videoView.setVideoPath(filepath);
