title: android layout dynamic sizing
body: <p>For many "header" TextViews across the pages I'm designing for a program, I would like them to be the parent.Width / 2 then properly aligned. While that would be fairly easy to code in the Java, I am attempting to do as much as possible in the XML layouts to avoid XML-Java code intersections until the last little bits (button presses, finish page, etc).</p>
  
  <p>Do I have to go through each page and calculate every item's specific width myself or is there a way to put something along the lines of "fill_parent / 2"?</p>
  
  <p>EDIT: Forgot to mention what is likely a key note - almost everything I am doing is in RelativeLayouts, I have very little use for LinearLayouts in this project.</p>
