Answer 1

I came across this link which contains the full source code on how to more items when reaching the end of scroll view.

Let me explain how he achieved this: What you need can be achieved by this part of the code (line 86 - 102)

listView.setOnScrollListener(new OnScrollListener(){

    @Override
    public void onScrollStateChanged(AbsListView view, int scrollState) {}

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

          int lastInScreen = firstVisibleItem + visibleItemCount;    
          if((lastInScreen == totalItemCount) && !(loadingMore)){     
            String url = "http://10.0.2.2:8080/CountryWebService" + 
            "/CountryServlet";
           grabURL(url); 
           }
      }
})

So in the above code, you can see that setOnScrollListener is called and in the onScroll, it's checked if the last item in the current listview is actually the last item. When that is true, it's fetching more items from the URL.
