Below logic will work for loading more data when you scroll to the top of the listview.

listview.setOnScrollListener(new AbsListView.OnScrollListener() {
        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {
            currentScrollState = scrollState;
            if (currentVisibleItemCount > 0 && currentScrollState == SCROLL_STATE_IDLE) {
                if (currentFirstVisibleItem == 0) {

                    // getMessages(); //write what you want to do when you scroll up to the end of listview.

                }
            }
        }

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

Hope this helps.
