title: Styling titleDivider in Dialog
body: <p>I am wondering how it is possible to get rid of (or change color) titleDivider in Dialog. It is a blue line below dialog title shown on honeycomb+ devices.</p>

  <p>I guess this is relevant piece of layout from SDK, but since there is no style attribute I dont know how to style it. If i try with findViewById there is no android.R.id.titleDivider</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:orientation="vertical"
      android:fitsSystemWindows="true"&gt;
      &lt;TextView android:id="@android:id/title" style="?android:attr/windowTitleStyle"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:minHeight="@android:dimen/alert_dialog_title_height"
          android:paddingLeft="16dip"
          android:paddingRight="16dip"
          android:gravity="center_vertical|left" /&gt;
      &lt;View android:id="@+id/titleDivider"
              android:layout_width="match_parent"
              android:layout_height="2dip"
              android:background="@android:color/holo_blue_light" /&gt;
      &lt;FrameLayout
          android:layout_width="match_parent" android:layout_height="wrap_content"
          android:layout_weight="1"
          android:orientation="vertical"
          android:foreground="?android:attr/windowContentOverlay"&gt;
          &lt;FrameLayout android:id="@android:id/content"
              android:layout_width="match_parent"
              android:layout_height="match_parent" /&gt;
      &lt;/FrameLayout&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>I have tried to override dialogTitleDecorLayout which is only reference to dialog_title_holo.xml in my theme.xml, but without success. Error is:</p>
  
  <blockquote>
    <p>error: Error: No resource found that matches the given name: attr
    'dialogTitleDecorLayout'.</p>
