title: Android: ListView in HorizontalScrollView performance issues
body: <p>I have a need for both horizontal and vertical scrolling of some data in my app. I've overridden <code>HorizontalScrollView</code> and I've allowed it to take an <code>Adapter</code> to populate its data. It behaves much like a horizontal <code>ListView</code> would behave, except I'm not doing any view recycling. Each item in my custom <code>HorizontalScrollView</code> is a <code>ListView</code> whose items are also populated with an <code>Adapter</code>. Each item in the <code>ListView</code> is a complex view.</p>
  
  <p>I'm able to scroll horizontally, and vertically just fine except that it's performance is a bit chunky. The getView() method in the adapter for populating the custom <code>HorizontalScrollView</code> is only called when the <code>Adapter</code> is first set on the view. However, I noticed that getView() is constantly being called for the ListViews in the <code>HorizontalScrollView</code>. I'm wondering is this is the performance problem?</p>
  
  <p><a href="https://stackoverflow.com/questions/4825086/horizontalscrollview-with-listview-documentation-bug">This question</a> points out a supposed documentation bug pertaining to using a <code>ListView</code> inside of a <code>HorizontalScrollView</code>, but the same warning is not given in the documentation for the vertically scrolling <code>ScrollView</code> documentation.</p>
  
  <p>Will I have performance issues if I put ScrollViews inside of the HorizontalScrollView?</p>
