You must create a scroll listener and add it to your listview.

yourListView.setOnScrollListener(this);

In the onScroll implementation

@Override
public void onScroll(AbsListView lw, final int firstVisibleItem,
             final int visibleItemCount, final int totalItemCount) {

    switch(lw.getId()) {
       case android.R.id.list:     
            final int lastItem = firstVisibleItem + visibleItemCount;
            if (lastItem == totalItemCount) {
                if(preLast != lastItem){ //to avoid multiple calls for last item
                    loadNextItems();
                    preLast = lastItem;
                }
            }
        }
    }


private void loadNextItems() {
    // Load your next items
    // Modify your adapter list and call adapter.notifyDataSetChange()
}

Hi,I have tried above. But when the list refreshed for the second time the previous contents are overwrited. how to avoid this? — Arj 1411, May 28 '15 at 12:09
put your loadNextItems code in your question, there must be a problem in it — Médéric, May 28 '15 at 13:28
