What you are searching for is called EndlessScrollListener. You will have to extend the class EndlessScrollListener and implement the onLoadMore method.

public class MyEndlessScrollListener extends EndlessScrollListener {

   @Override
   public void onLoadMore(int page, int totalItemsCount) {
        loadData(page);  
   }
}

And set the listener on the listView :

listView.setOnScrollListener(new EndlessScrollListener());

You can use the other constructors of the EndlessScrollListener if you want.
