title: Rounded corners on material button
body: <p>I'm following the tips from questions like <a href="https://stackoverflow.com/questions/26346727/android-material-design-button-styles">this</a> to create a button style like suggested on Material Design.</p>
  
  <p><a href="https://i.stack.imgur.com/Xa3cE.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Xa3cE.png" alt="Button"></a></p>
  
  <p>However, I need to change the corner radius and haven't been able to do so by inheriting <code>Widget.AppCompat.Button.Colored</code> style and setting the radius parameter.</p>
  
  <p>How can I have the same style but with rounded corners?</p>
