Center two buttons horizontally

I know you've already found a solution, but you might also find this useful. The empty TextView used as the center reference can double as padding between the buttons by increasing the dip setting. It also handles screen orientation changes well.

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <Button
        android:id="@+id/button1"
        android:text="Left"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_toLeftOf="@+id/centerPoint" />

    <TextView
        android:id="@+id/centerPoint"
        android:text=""
        android:layout_width="0dip"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true" />

    <Button
        android:id="@+id/button2"
        android:text="Right"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_toRightOf="@+id/centerPoint" />

</RelativeLayout>

This is my solution:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="wrap_content"
    android:layout_centerHorizontal="true">

    <TextView
        android:text="@+id/SomeText"
        android:id="@+id/TextView01"
        android:layout_width="wrap_content" android:layout_height="wrap_content" />

    <LinearLayout
        android:orientation="horizontal"
        android:background="@android:drawable/bottom_bar"
        android:paddingLeft="4.0dip"
        android:paddingTop="5.0dip"
        android:paddingRight="4.0dip"
        android:paddingBottom="1.0dip"
        android:layout_width="fill_parent" android:layout_height="wrap_content"
        android:layout_below="@+id/TextView01">

        <Button
            android:id="@+id/allow"
            android:layout_width="0.0dip" android:layout_height="fill_parent"
            android:text="Allow"
            android:layout_weight="1.0" />

        <Button
            android:id="@+id/deny"
            android:layout_width="0.0dip" android:layout_height="fill_parent"
            android:text="Deny"
            android:layout_weight="1.0" />

    </LinearLayout>
</RelativeLayout>
