title: Android - drawing cache - when is it useful?
body: <p>I am reading about <code>setDrawingCacheEnabled</code> and <code>getDrawingCache</code> and I was wondering when is it good to use it or when its not good.</p>
  
  <p>Basically in my case I have an <code>HorizontalScrollView</code> with many things inside it so its scrolls left/right and most of the things are not visible.</p>
  
  <p>If I use <code>setDrawingCacheEnabled(true)</code> on the views, does it help?  or this is only when I use custom views and I call <code>getDrawingCache()</code>?</p>
  
  <p>Is there any other 'cache' way to use in a <code>HorizontalScrollView</code>?</p>
