title: Adding Options to Options Menu from Activity Class
body: <p>How can I show the value in my <code>EditText</code> into an optionsMenu on <code>Button</code> click?</p>
  
  <p>E.g. If I enter <em>abc</em> in <code>EditText</code> and then I press a <code>Button</code> (add <code>Button</code>), then I should be getting an optionsMenu with <em>abc</em> added into it.</p>
