smoothScrollToPositionFromTop() is not always working like it should

This is a known bug. See https://code.google.com/p/android/issues/detail?id=36062

However, I implemented this workaround that deals with all edge cases that might occur:

First call smothScrollToPositionFromTop(position) and then, when scrolling has finished, call setSelection(position). The latter call corrects the incomplete scrolling by jumping directly to the desired position. Doing so the user still has the impression that it is being animation-scrolled to this position.

I implemented this workaround within two helper methods:

smoothScrollToPositionFromTop()

public static void smoothScrollToPositionFromTop(final AbsListView view, final int position) {
    View child = getChildAtPosition(view, position);
    // There's no need to scroll if child is already at top or view is already scrolled to its end
    if ((child != null) && ((child.getTop() == 0) || ((child.getTop() > 0) && !view.canScrollVertically(1)))) {
        return;
    }

    view.setOnScrollListener(new AbsListView.OnScrollListener() {
        @Override
        public void onScrollStateChanged(final AbsListView view, final int scrollState) {
            if (scrollState == SCROLL_STATE_IDLE) {
                view.setOnScrollListener(null);

                // Fix for scrolling bug
                new Handler().post(new Runnable() {
                    @Override
                    public void run() {
                        view.setSelection(position);
                    }
                });
            }
        }

        @Override
        public void onScroll(final AbsListView view, final int firstVisibleItem, final int visibleItemCount,
                                 final int totalItemCount) { }
    });

    // Perform scrolling to position
    new Handler().post(new Runnable() {
        @Override
        public void run() {
            view.smoothScrollToPositionFromTop(position, 0);
        }
    });
}

getChildAtPosition()

public static View getChildAtPosition(final AdapterView view, final int position) {
    final int index = position - view.getFirstVisiblePosition();
    if ((index >= 0) && (index < view.getChildCount())) {
        return view.getChildAt(index);
    } else {
        return null;
    }
}

Here is an implementation of the solution.

    void smoothScrollToPositionFromTopWithBugWorkAround(final AbsListView listView,
                                                    final int position,
                                                    final int offset, 
                                                    final int duration){

    //the bug workaround involves listening to when it has finished scrolling, and then 
    //firing a new scroll to the same position.

    //the bug is the case that sometimes smooth Scroll To Position sort of misses its intended position. 
    //more info here : https://code.google.com/p/android/issues/detail?id=36062
    listView.smoothScrollToPositionFromTop(position, offset, duration);
    listView.setOnScrollListener(new OnScrollListener() {

        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {
            if(scrollState==OnScrollListener.SCROLL_STATE_IDLE){
                listView.setOnScrollListener(null);
                listView.smoothScrollToPositionFromTop(position, offset, duration);
            }

        }

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
        }
    });
}
