title: Android Material Chip Theme overriding
body: <p>I want to customize a Material chip.</p>
  
  <p>I would think this is how to do it:</p>
  
  <p></p>
  
  <pre><code>&lt;style name="AppTheme" parent="Theme.MaterialComponents.NoActionBar"&gt;
  
      .... lots more theme stuff here
  
      &lt;item name="chipStyle"&gt;@style/MaterialChips&lt;/item&gt;
      &lt;item name="chipGroupStyle"&gt;@style/MaterialChips&lt;/item&gt;
      &lt;item name="chipStandaloneStyle"&gt;@style/MaterialChips&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="MaterialChips" parent="Widget.MaterialComponents.Chip.Choice"&gt;
      &lt;item name="chipBackgroundColor"&gt;@color/chips&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p></p>
  
  <p>None of the tags like <code>chipStyle</code> affect the chips. But if I set <code>app:chipBackgroundColor="@color/chips"</code> in xml it works.</p>
  
  <p>It also works fine like this for other things like say <code>&lt;item name="materialAlertDialogTheme"&gt;@style/AlertDialogTheme&lt;/item&gt;</code>.</p>
  
  <p>The material documentation (if you can call it that) is really not helping.</p>
