title: Android Spinner hint?
body: <p>I have two spinners in my current android app, I would like to have a default value like the editText's android:hint ability. Is there a way to do so, but in a way that doesn't add the hint to the string array that populates the spinner. e.g. it's impossible to choose the hint from the spinner list.</p>
  
  <p>Also, is there a way to check if the user has selected a valid value and if not take an action. I do this in my editTexts by getting the value to a string and then:</p>
  
  <p><code>if (calculator_ShutterSpeed_TempValue.equals("") ){
      action
  }</code></p>
  
  <p>And can I set the spinner back to it's hint value on another button press?</p>
  
  <p>So what I am for asking is:</p>
  
  <ol>
  <li>Spinner hint that is not possible to be redisplayed after the user has clicked on the spinner?</li>
  <li>Check if the user has selected a valid value from the spinner, (have they selected a value beyond the default hint one)?</li>
  <li>Redisplay the hint on click of a reset button?</li>
  </ol>
