title: setPrompt on Spinner doesn't work
body: <p>I am very new to android development and I seem to have an issue that I cannot understand.  I have a spinner and the values are getting set just fine but my prompt is not appearing.  I have attempted to set this in both the xml and the java code and neither one works at all.  Below is my configuration.  I feel that I am missing something fundamental but I don't know what it is yet.</p>
  
  <p>Any help would be appreciated.  Craig</p>
