title: ListView with Refresh and LoadMore option not working
body: <p>The problem is based upon a specific use case, which is as follows:
  1) Go the end of list and load more data until the API returns an empty list
  2) After that call refresh() and the layout will refresh but the issue is that after I call refresh() the loadmore() doesn't gets called.</p>
  
  <p>I have used SuperListView, I have used EndlessScrollListener with official SwipeToRefreshLayout, but nothing works.</p>
  
  <p>I might be using the adapter in a wrong way I guess but below are the code snippets which I am using:</p>
  
  <pre><code>void showContent(){
    contentListModel = ((ContentListModel) baseModel);
    contentAdapter =  ContentAdapter(getActivity(),R.layout.content_item,contentListModel.getContents());
    mListView.setAdapter(contentAdapter);
  }
  
  void showRefreshContent(){
    contentListModel = new ContentListModel();
    contentAdapter.clear();
    contentListModel = ((ContentListModel) baseModel);
    contentAdapter.addAll(contentListModel.getContents());
    mListView.setAdapter(contentAdapter);
  }
  
  void showLoadMoreContent(){
    contentListModel = ((ContentListModel) baseModel);
    contentAdapter.addAll(contentListModel.getContents());
    contentAdapter.notifyDataSetChanged();
  }
  </code></pre>
  
  <p>I could share the complete code but that might be irrelevant I guess, for backend I am using Spring + Android Annotations + [Observer + Facade] Design Patterns.</p>
  
  <p>Thanks in advance.  </p>
  
  <p>EndlessScrollListener</p>
