Android onScrollStateChanged fires twice after having reached bottom

I'm trying to detect when a user has gotten to the end of the listview. All of the posts on here have said to use onScrollStateChanged or onScroll. The problem I am having with this is that the onScrollStateChanged will print out twice instead of once (depends on how many items there are in the listview).

            if (timeline_arg.size() != 0)
            { 
                if (mListView.getLastVisiblePosition() == mListView.getAdapter().getCount() -1
                        && mListView.getChildAt(mListView.getChildCount() -1).getBottom() <= mListView.getHeight())
                {
                    if (!swipeRefreshLayout.isRefreshing())
                    {
                        List<Status> test =  loadOlderTweets(); 
                        insertTimeline(test, "true");                           
                    }
                }
            }
