If you use a RelativeLayout for the root of your activity, you can align other views to the bottom of the screen. This, combined with a LinearLayout as a container, will provide a flexible panel for putting your navigation bar in:

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

    <LinearLayout 
    android:layout_alignParentBottom="true" 
    android:layout_centerHorizontal="true"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"
    android:orientation="horizontal">

        <Button 
        android:layout_height="wrap_content" 
        android:id="@+id/back" 
        android:text="Back"
        android:layout_width="wrap_content" />

        <Button 
        android:layout_height="wrap_content" 
        android:id="@+id/home" 
        android:text="Home" 
        android:layout_width="wrap_content" />

        <Button 
        android:layout_height="wrap_content" 
        android:id="@+id/next" 
        android:text="Next" 
        android:layout_width="wrap_content" />

    </LinearLayout>

</RelativeLayout>
