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>
