    i got that how to combine VideoView and GestureListener :

    layout file activity_main.xml :

    
    
       
    
    
    

    MainActivity.java file :

    public class MainActivity extends Activity implements SimpleGestureListener {
    
    VideoView videoView;
    MainActivity activity;
    MediaController mediaController;
    AudioManager audioManager;
    GestureDetection detector;
    int currentPosition;
    int currentVolume;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
        videoView = (VideoView) findViewById(R.id.videoView);
        detector = new GestureDetection(this, this);
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT,
                android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI);
        intent.setType("audio/*");
        startActivityForResult(intent, 1);
    }
    
    @Override
    public boolean dispatchTouchEvent(MotionEvent me) {
        // Call onTouchEvent of SimpleGestureFilter class
        this.detector.onTouchEvent(me);
        return super.dispatchTouchEvent(me);
    }
    
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);
    
        String filePath = null;
    
        if (requestCode == 1) {
    
            switch (resultCode) {
    
            case RESULT_OK:
                Uri selectedAudio = data.getData();
                String[] filePathColumn = { MediaStore.Audio.Media.DATA };
    
                Cursor cursor = getContentResolver().query(selectedAudio,
                        filePathColumn, null, null, null);
                cursor.moveToFirst();
    
                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                filePath = cursor.getString(columnIndex);
                cursor.close();
                break;
            default:
                finish();
            }
            if (filePath != null) {
                mediaController = new MediaController(this);
                mediaController.setAnchorView(videoView);
                Uri uri = Uri.parse(filePath);
                videoView.setMediaController(mediaController);
                videoView.setVideoURI(uri);
                videoView.requestFocus();
                videoView.start();
            } else
                finish();
        }
    }
    
    @Override

        }
        Toast.makeText(this, str, Toast.LENGTH_SHORT).show();
    }
    
    }
