        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {
            if (SCROLL_STATE_TOUCH_SCROLL == scrollState) {
                View currentFocus = getCurrentFocus();
                if (currentFocus != null) {
                    currentFocus.clearFocus();
                }
            }
        }

    }
