title: alignment issue with gridlayout
body: <p>I have a number pad as shown</p>
  
  <p><img src="https://i.stack.imgur.com/kZBw1.png" alt="here"></p>
  
  <p>As you can see, buttons with only single line are not properly aligned. I got to know that by setting <code>android:baselineAligned</code> as false we can solve this. But GridLayout does not have any such property.</p>
  
  <p>How can i solve it?</p>
