title: LinearLayout height in onCreate is 0
body: <p>I'm trying to dynamically adjust the height of my rows depending on the (screen height - my layout height) / list.size.</p>
  
  <p>Unfortunately in the <code>onCreate</code> method the layout height returns null (not so when i call it in an on click listener).</p>
  
  <p>Is there another method I can call it in?</p>
