如何使用Android Holo Theme风格的对话框按钮

I'm creating a Dialog Box on Holo Theme and want to follow the OS default way of displaying the buttons. So far I have created the dialog box but the buttons don't render in the way it does in the apps done in Holo for ICS. How can I do this? My intended look & feel is and I am able to reach till here

有点晚了，但也许有人对此仍然感兴趣。

这对我来说效果很好。

<!--
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>

加载此布局的活动需要 Holo.Dialog 主题。

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