a bit late, but maybe someone is still interested in that.

this works pretty good for me.

EDIT: be carefull, "?android:attr/dividerHorizontal" is only supported since API 11
      just avoid it in prior OSs.

<View
    android:layout_width="fill_parent"
    android:layout_height="1dip"
    android:background="?android:attr/dividerHorizontal" />
<LinearLayout 
    style="?android:attr/buttonBarStyle"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:paddingTop="0dip"
    android:paddingLeft="2dip"
    android:paddingRight="2dip"
    android:measureWithLargestChild="true">

    <Button 
        android:id="@+id/cancel"
        style="?android:attr/buttonBarButtonStyle"
        android:layout_width="0dip"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="@android:string/cancel"/>
    <Button 
        android:id="@+id/ok"
        style="?android:attr/buttonBarButtonStyle"
        android:layout_width="0dip"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="@android:string/ok"/>
</LinearLayout>

the activity that loads this layout needs the Holo.Dialog theme.

android:theme="@android:style/Theme.Holo.Dialog"
