使用VideoView播放视频

1.  布局文件
   

< VideoView
    android:id = "@+id/video"
    android:layout_width = "match_parent"
    android:layout_height = "match_parent"  />

2.  安卓代码

public  class  MainActivity  extends  AppCompatActivity {
    private  VideoView videoView=  null ;
    private  MediaController mediaController;
    @Override
    protected  void  onCreate(Bundle savedInstanceState) {
        super .onCreate(savedInstanceState);
        getWindow().setFormat(PixelFormat.TRANSLUCENT);
        setContentView(R.layout.activity_main);
        videoView = (VideoView)findViewById(R.id.video);
        mediaController =  new  MediaController( this );
        File video =  new  File( "/mnt/usb/sda1/test.mp4" );
        if (video.exists()) {
            videoView.setVideoPath(video.getAbsolutePath());
            videoView.setMediaController(mediaController);
            mediaController.setMediaPlayer(videoView);
            videoView.requestFocus();
        }
    }
}

3. 在AndroidMainFest.xml中添加

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"></uses-permission>
