title: Content of Dialog dims as well as background
body: <p>I have a custom dialog activity containing a camera preview inside of a FrameLayout.</p>
  
  <pre><code>&lt;FrameLayout
      android:id="@+id/camera_preview"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_weight="3" /&gt;
  </code></pre>
  
  <p>When the dialog is brought up, the background is dimmed like normal, but the FrameLayout is dimmed as well.</p>
  
  <p>I tried removing the dim with a custom style, but that also removed the dimming behind the dialog.</p>
  
  <pre><code>&lt;style name="Theme.DoNotDim" parent="android:Theme.Holo.Dialog"&gt;
      &lt;item name="android:backgroundDimEnabled"&gt;false&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>Is there any way to stop the dimming of the FrameLayout while keeping the normal background dimming?</p>
