title: CursorTreeAdapter and getChildType
body: <p>I'm trying to use <code>custom CursorTreeAdapter</code> with two different types of child items.
  I want to use <code>getChildType(int groupPosition, int childPosition)</code> method inside <code>newChildView</code> method</p>
  
  <pre><code> @Override
   protected View newChildView(Context context, Cursor cursor,boolean isLastChild, ViewGroup parent)   {
      View view = null;
  
      switch(getChildType(**groupPosition**, cursor.getPosition())){
      case TYPE_CHILD_1:
          view = inflater.inflate(...);
      break;
      case TYPE_CHILD_2:
          view = inflater.inflate(...);
      break;
      }
      return view;
  }
  </code></pre>
  
  <p>But there is no <code>groupPosition arg</code> inside <code>newChildView</code> method. How can I get <code>groupPosition</code>?</p>
