title: Show AlertDialog on top of another AlertDialog
body: <p>I'm taking some personal details from user in a form which is actually a custom <code>Alertdialog</code>. Now when user presses <strong>Submit</strong> button present within the <code>Alertdialog</code>, if there is an validation error; I'm trying to display another <code>Alertdialog</code> with error message like <em>Please Enter First Name</em>.</p>
  
  <p>What is happening is when 2nd <code>Alertdialog</code> is being displayed due to a validation error, the main <code>Alertdialog</code> (registration form) gets disappeared.</p>
  
  <p>Any reason what might me causing this. Any help appreciated.</p>
  
  <h2>Edit</h2>
  
  <p>Please note that I have considered <code>setError</code> but I also have some other views like <code>Spinner</code>, <code>RadioButton</code> in my layout. So just using <code>setError</code> for <code>EditText</code> is not whole solution for my problem.</p>
