title: Moving hint text in textview
body: <p>I notice in the hangouts app that the hint text in their TextView fields moves upward and reduces its size upon entry of the first character in the text fields.</p>
  
  <p>When I specify hint text in a TextView, the hint text simply disappears upon entry in a text field.</p>
  
  <p>Is the hangouts behavior using some a automatic feature of the TextView that I am not aware of, or are they just hard coding it?</p>
  
  <p>Thanks,
  Dean
