title: Spinner onItemSelected called erroneously (without user action)
body: <p>I have a spinner which I am showing in a dialog view, and the moment the dialog starts <code>onItemSelected</code> is called.  I don't really want to process this but only when user makes the selection.  So I either need to prevent this (maybe because no default value is set?), or I need to know it is not the user that is making this selection?</p>
