title: What is the most used layout in Android?
body: <p>I am trying to add 4 buttons to the centre of the screen such that it should appear as:</p>
  
  <pre><code>            Button 1    Button 2
              Button 3    Button 4
  </code></pre>
  
  <p>What is the best layout method for this? Or how can I do it with different layouts.
  I tried with tablelayout but the final product shifted positions in different screen sizes.</p>
  
  <p>Thanks for your help!</p>
