title: listview does not show some item
body: <p>Good afternoon!
  listview does not show some items on some devices. Between some items there are empty space.</p>
  
  <p>Imageview (i'm using universal image loader) and textview are loading of internet.
  If you reduce the quality of the images on the server, then item be. I do not understand how it is works</p>
  
  <p>getView :</p>
  
  <pre><code>       View v = convertView;
      ViewHolder viewHolder;
      if (v == null) {
          viewHolder = new ViewHolder();
