title: Android registration form
body: <p>I am designing the registration form for my application.</p>
  
  <p>I am trying to make it look like that;</p>
  
  <p><img src="https://i.stack.imgur.com/FuEQH.jpg" alt="I am sorry for this big image"></p>
  
  <p>Meanwhile I have succeeded designing the components as I want (With linear layout and rounded corners),
  but I can not identify <strong>why the button does not appear on the screen</strong>?</p>
