private intgetViewOffset(android.view.View v)
Gets the left position of v in this view. Throws if v is not a child of this.

            } else {
                throw new RuntimeException(v + " is not a child of " + this);
            }

public booleanonTouchEvent(android.view.MotionEvent event)
Ensure that, if there is no target under us to receive the touch, that we process it ourself. This makes sure that onInterceptTouchEvent() is always called for the entire gesture.

        if (event.getAction() != MotionEvent.ACTION_DOWN) {
            mService.interceptTouchEvent(event);
        }
        return true;
