title: Update ListView item outside of adapter
body: <p>I have a ListView where each item represents a podcast. Selecting an item plays the podcast.  While playing, the view for that ListView item displays an elapsed time counter with a SeekBar next to it to show progress.</p>
  
  <p>Where I'm having a problem is figuring out how to handle updating the elapsed time counter (a TextView) while the SeekBar is being repositioned by touch.  Calling <code>notifyDataSetChanged</code> during the <code>onProgressChanged</code> SeekBar event doesn't seem to work very well.</p>
