title: (android) rows of buttons that take up the entire width of the screen
body: <p>I am trying to make 3 rows of 4 buttons each that will take up the entire width of the screen. I have tried Linear Layout but have trouble adding a second row and from what I have read nesting Linear Layouts is bad practice. I tried to use relative layout several times but I cannot manage to get the buttons to fill the width of the screen because it ignores layout_weight, I then tried nesting linear layout in relative layout but layout_weight is still ignored.</p>
  
  <p>What is the best way to accomplish this?</p>
