希望这段代码对你有帮助

public class video extends Activity{

    VideoView video_view;
    String ex_name;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.eccryption);
        video_view = (VideoView) findViewById(R.id.videoView1);

        ex_name = getIntent().getExtras().getString("video_name");

        MediaController mediaController = new MediaController(this);
        mediaController.setAnchorView(video_view);
        video_view.setMediaController(new MediaController(this));
        handler.sendEmptyMessage(1);

    }

    Handler handler = new Handler(){

        public void handleMessage(Message msg){

            int pos=msg.what;
            if (pos == 1){

                video_view.setVideoPath(Environment.getExternalStorageDirectory()+"/"+ex_name+".mp4");
                video_view.requestFocus();
                video_view.start();

                Log.d("Before Video Finish", "i m in before video finish");
                video_view.setOnCompletionListener(new OnCompletionListener() {
                    @Override
                    public void onCompletion(MediaPlayer mp) {
                        finish();
                    }
                });
            }
        }
    };
