How to combine OnClickListener and OnTouchListener for an ImageButton

Question

I need to do something when the user clicks the ImageButton I\'ve tried to create a static class that implements both OnClickListener

Answer 1

Use this code:

public class GestureHelper implements OnTouchListener {

private final GestureDetector mGestureDetector;

public GestureHelper(Context context) {
    mGestureDetector = new GestureDetector(context, new GestureListener(this));
}

public void onSwipeRight() {
};

public void onSwipeLeft() {
};

public void onSwipeTop() {
};

public void onSwipeBottom() {
};

public void onDoubleTap() {
};

public void onClick() {
};

@Override
public boolean onTouch(View v, MotionEvent event) {
    return mGestureDetector.onTouchEvent(event);
}

private static final class GestureListener extends SimpleOnGestureListener {

    private static final int SWIPE_THRESHOLD = 100;
    private static final int SWIPE_VELOCITY_THRESHOLD = 100;
    private GestureHelper mHelper;

    public GestureListener(GestureHelper helper) {
        mHelper = helper;
    }

    @Override
    public boolean onDown(MotionEvent e) {
        return true;
    }

    @Override
    public boolean onSingleTapUp(MotionEvent e) {
        mHelper.onClick();
        return true;
    }

    @Override
    public boolean onDoubleTap(MotionEvent e) {
        mHelper.onDoubleTap();
        return true;
    }

    @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
        boolean result = false;
        try {
            float diffY = e2.getY() - e1.getY();
            float diffX = e2.getX() - e1.getX();
            if (Math.abs(diffX) > Math.abs(diffY)) {
                if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffX > 0) {
                        mHelper.onSwipeRight();
                    } else {
                        mHelper.onSwipeLeft();
                    }
                }
            } else {
                if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffY > 0) {
                        mHelper.onSwipeBottom();
                    } else {
                        mHelper.onSwipeTop();
                    }
                }
            }
        } catch (Exception ex) {
            ex.printStackTrace();
        }
        return result;
    }
}

}

Extend this class and use like this...

view.setOnTouchListener(new SomeYourGestureHelper(context, someParameters));
