title: ignore OnItemSelectedListener firing on create
body: <p>I'm creating a <code>spinner</code> and I've added an <code>OnItemSelectedListener</code> to it.
  However I've noticed that it fires on create.
  Now I was wondering if there was a way to ignore/discard it.</p>
  
  <p>I know I could use a <code>boolean</code> value, but that's a bit "dirty".</p>
