Vertical Seekbar popup at thumb. Popup misplace

Question

I am working on a app where I am using both Horizontal and Vertical seekbar with showing popup at thumb location.

1. For horizontal seekbar both the things are fine.

2. But when we rotate seekbar by -90/270 degree, then the popup is not showing on proper location(above the thumb)

3. The problem is we try to get bound of Seekbar thumb for vertical position but i am getting bound of horizontal position.

Any help is appreciable.

    Try this vertical seekbar. As you see in **setProgress(int progress)** method thumb position will update, automatically. Good
 luck

                    setProgress(getMax() - (int) (getMax() * event.getY() / getHeight()));
                    onSizeChanged(getWidth(), getHeight(), 0, 0);
                    break;

                case MotionEvent.ACTION_CANCEL :
                    break;
