title: Fragment doesn't call onSaveInstanceState when swiping ViewPager?
body: <p>I'm having an issue with the ViewPager where my ListView is loosing it's scroll position.</p>
  
  <p>The state of the ListView can easily be stored and restored using:</p>
  
  <pre><code>@Override
  public View onCreateView (LayoutInflater inflater, ViewGroup container,
          Bundle savedInstanceState) 
  {
      View v = inflater.inflate(R.layout.frag_cool_things, container, false);
  
      AdvListView listView = (AdvListView) v.findViewById(R.id.lv0);
      listView.setOnItemClickListener( mOnListItemClicked );
  
      if (null != savedInstanceState)
      {
          listView.onRestoreListViewInstanceState(savedInstanceState.getParcelable("list_state"));
      }
  
      mListView = listView;
  
      return v;
  }
  
  @Override
  public void onSaveInstanceState (Bundle outState) 
  {
      super.onSaveInstanceState(outState);
  
      outState.putParcelable("list_state", mListView.onSaveListViewInstanceState());
  }
  </code></pre>
  
  <p>However the problem is that when fragments are being swiped <code>onDestroyView()</code> gets called but never calls <code>onSaveInstanceState (Bundle outState)</code>.</p>
  
  <p>Rotating the screen and such restores the <code>ListView</code> state just fine but swiping I can't figure out how to restore the list properly.</p>
