I want dynamically fill listview with List It is my code:

ListView lis;
List<String> values=new  ArrayList<String>();
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_pages, container, false);
    values.add("a1");
    values.add("a2");
    values.add("a3");
    values.add("a4");
    values.add("a5");
    values.add("a6");
    values.add("a7");
    values.add("a8");
    values.add("a9");
    values.add("a10");
    values.add("a11");
   lis =(ListView)rootView.findViewById(R.id.listView1);
 final    ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(rootView.getContext(), android.R.layout.simple_list_item_1,values );
     lis.setAdapter(arrayAdapter);
     lis.setOnScrollListener(new OnScrollListener() {

        public void onScrollStateChanged(AbsListView view, int scrollState)
        {  
               int first = view.getFirstVisiblePosition();
                int count = view.getChildCount();

                if (scrollState == SCROLL_STATE_IDLE || (first + count > arrayAdapter.getCount()) ) {
                    fill_list();
                }
        }   

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



        }
    });  
    return rootView;
}

First, remember to call list.notifyDataSetChanged(); when you want to update listView content.

Also for this case I recommend you use a custom Adapter and implement your methods manually so you con override notifyDataSetChanged() method, maybe something like:

public class MyAdapter entends BaseAdapter{ 
    //Stuff...
    public void notifyDataSetChanged(){
        fillList();
        super.notifyDataSetChanged();
    }
}

Hope this helps, sorry for my pseudocode.

Best regards.
