IllegalArgumentException parameter must be a descendant of this view at ViewGroup.offsetRectBetweenParentAndChild

Question

I got following exception from one of my app user in crash logs. Unable to understand from the log trace. If anybody has some thoughts, please share.

Fatal Exception: java.lang.IllegalArgumentException parameter must be a descendant of this view raw

I fixed this error by adding a custom listener like this :

protected class MyScrollListener implements OnScrollListener {

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem,
                int visibleItemCount, int totalItemCount) {
            // do nothing 
        }

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

    }

Then use the listener you created :

listview.setOnScrollListener(MyScrollListener);
