title: cacheColorHint causing laggy scroll in listView
body: <p>I am having this strange issue with listView and cacheColorHint..</p>
  
  <p>I have the background of the activity set to a gradient..</p>
  
  <p>When I set the <code>android:cacheColorHint="#00000000"</code> the scrolling becomes laggy, else it is super smooth.</p>
  
  <p>I also tried programatically setting it...same laggy scrolling(dumb thing to think that it'd work )</p>
  
  <p>When I don't set it...I have the flickering when I scroll that is why I set the cacheHintColor in the first place.....</p>
  
  <p>It is the same problem as seen in this question although it seems it hasn't been solved..</p>

  <p>I've seen many applications which have smooth scrolling in-spite of having all sorts of backgrounds...so pease suggest a workaround or a fix please...</p>
  
  <p>Additional details:
  App is a twitter client uses lists in a ListFragment.
  Each list item contains an image loaded from twitter...I'm using an opensource image loader class which works well(cant quite remember which one)...but since scrolling works well if cacheHintColor not set..hence I can rule out that the problem is with the image caching...</p>
