title: Dialog box with EditText and Spinner
body: <p>I have a button that pops up with a dialog box on click.</p>
  
  <p>I want the dialog box to have an <code>EditText</code> and a <code>Spinner</code> inside the dialog box.</p>
  
  <p>I don't know how I'd set the view for it, I have the code for an <code>AlertDialog</code> and it works, it's just the <code>EditText</code> and <code>Spinner</code> that I need to place inside it then I can get on with the rest of the app's code.</p>
  
  <p>Please can someone show me how I'd add an <code>EditText</code> and <code>Spinner</code> please?</p>
