 MainActivity

public class MainActivity extends AppCompatActivity implements GestureDetector.OnGestureListener {


    private GestureDetector mDetector;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        mDetector=new GestureDetector(this,this);

    }
    @Override

            return true;
        }

    }

    String TAG="log:";
    @Override

        return false;
    }

    @Override
    public void onShowPress(MotionEvent motionEvent) {
