title: Using a Material-based Dialog Theme with AppCompat
body: <p>I have an activity in my Manifest I used to style with a Dialog Theme.  I can not find how to replace this in <code>AppCompat</code> library.</p>
  
  <pre><code>  &lt;activity
              android:name=".LoginActivity"
              android:theme="@android:styles/Theme.Holo.Dialog" 
              android:configChanges="orientation|screenSize|keyboardHidden"
              android:label="Login" &gt;
  </code></pre>
  
  <p>Is there a Material-based equivalent?</p>
