title: How can I center two TextViews vertically within a Layout
body: <p>I have a <code>RelativeLayout</code> (that I am not married to) and two <code>TextView</code>s.  I would like the bottom of the first <code>TextView</code> to line up with the center of it's parent, and the top of the second <code>TextView</code> to line up with the center of it's parent.</p>
  
  <p><img src="https://i.stack.imgur.com/FvXGb.png" alt="enter image description here"></p>
  
  <p>I put a green line in the picture above at the (vertical) center of the parent.  The <code>TextView</code>s are currently in exactly the right spot, but I did this as I will describe below with margin's and aligning them to the parent and knowing the parent's size.  </p>
  
  <p>For various reasons I can't use just one <code>TextView</code> and center it.  Also I don't know the height of the parent, so I can't align each to the top/bottom of the parent and margin them down/up to center them.  </p>
  
  <p>I also tried having another <code>View</code> that takes up half the height and be <code>invisible</code>, but <code>layout_height</code> doesn't take percents (or at least it gave me errors).</p>
  
  <p>Any ideas how I can accomplish this?</p>
  
  <p>Should I just put the two <code>TextView</code>s inside another layout and have that center itself?</p>
