title: Setting a Spinner adapter to null
body: <p>I have a android spinner to load to do some selection and I'm loading data to it. There is a situation I want to set the data to load in spinner to null. This helped me to select the position, <code>sizeSP.setSelection(0);</code>
  But I want to set the data to be load to null. So when clicked on the spinner it shouldn't anything.</p>
