You can use list view scroll listener. Here i created list view to get event when list view scroll to the last item. you can use this and create your logic.

listHome.setOnScrollListener(new OnScrollListener() {

        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {
            // TODO Auto-generated method stub
        }

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem,
                int visibleItemCount, int totalItemCount) {
            // TODO Auto-generated method stub



                if (firstVisibleItem + visibleItemCount == totalrecord && totalItemCount != 0) {

                }

    });
