This is what I did to resolve the issue. Essentially, we want to keep calling smoothscrolling until you reach the desired element (in this case, I simply want to scroll to the top, which is element 0).

//There is a known bug where smoothScrollToPosition(..) may not reach the top, 
            //if the list is very large, keep scrolling until you reach the top element
            newsFeed.setOnScrollListener(new OnScrollListener() {
                @Override
                public void onScrollStateChanged(AbsListView view, int scrollState) {

                }

                @Override
                public void onScroll(AbsListView view, int firstVisibleItem,
                        int visibleItemCount, int totalItemCount) {
                    if(firstVisibleItem != 0) {
                        newsFeed.smoothScrollToPosition(0);
                    } 
                    else {
                        //We are done
                        newsFeed.setOnScrollListener(null);
                    }
                }
            });
            newsFeed.smoothScrollToPosition(0);
