Android Tutorial => Basic Gesture Detection

Example

public class GestureActivity extends Activity implements
        GestureDetector.OnDoubleTapListener,
        GestureDetector.OnGestureListener {

    private GestureDetector mGestureDetector;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mGestureDetector = new GestureDetector(this, this);
        mGestureDetector.setOnDoubleTapListener(this);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event){
        mGestureDetector.onTouchEvent(event);
        return super.onTouchEvent(event);
    }

    @Override
    public boolean onDown(MotionEvent event) {
        Log.d("GestureDetector","onDown");
        return true;
    }

    @Override
    public boolean onFling(MotionEvent event1, MotionEvent event2, float velocityX, float velocityY) {
        Log.d("GestureDetector","onFling");
        return true;
    }

    @Override
    public void onLongPress(MotionEvent event) {
        Log.d("GestureDetector","onLongPress");
    }

    @Override
    public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
        Log.d("GestureDetector","onScroll");
        return true;
    }

    @Override
    public void onShowPress(MotionEvent event) {
        Log.d("GestureDetector","onShowPress");
    }

    @Override
    public boolean onSingleTapUp(MotionEvent event) {
        Log.d("GestureDetector","onSingleTapUp");
        return true;
    }

    @Override
    public boolean onDoubleTap(MotionEvent event) {
        Log.d("GestureDetector","onDoubleTap");
        return true;
    }

    @Override
    public boolean onDoubleTapEvent(MotionEvent event) {
        Log.d("GestureDetector","onDoubleTapEvent");
        return true;
    }

    @Override
    public boolean onSingleTapConfirmed(MotionEvent event) {
        Log.d("GestureDetector","onSingleTapConfirmed");
