title: Gridlayout with borders
body: <p>I'm a new Android developer, and I'm just trying to improve my skill by reading some samples, I want to design a new interface using GridLayout, I've checked a lot of samples but I can't seem to draw borders between the GridLayout cells. What could I be missing?</p>
  
  <p>Here is  a link that I went through it, but the borders didn't show up!</p>
