How to make a proper button bar on ICS

button_bar_layout.xml

<!--
  A button bar is a set of buttons at the bottom of an activity.
  An example is an AlertDialog with OK/Cancel buttons.

  Note that something similar can be accomplished using a
  split action bar and text-only action buttons, but this is an
  alternate presentation that's often preferred.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:divider="?android:attr/dividerHorizontal"
    android:showDividers="middle">

    <TextView android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:gravity="center"
        android:text="Hello World" />
