title: Actionbar.getHeight() returning different values between API 16 and 17
body: <p>I need to set a View's <code>topMargin</code> by the <code>Actionbar</code> height so it's visible under the <code>Actionbar</code>. I do this in my <code>onCreateOptionsMenu</code>, thinking the <code>Actionbar</code> is drawn at that point. My app targets API 14 and above only.</p>
  
  <p>Running an emulator with API 17, <code>getHeight()</code> returns a good value of 96dp. But running the same code on an emulator with API 16, a height of zero is returned, likely because it hasn't been drawn yet.</p>
  
  <p>Why would there be a difference between the two APIs?</p>
