@Romain:
Thanks for clarification on the framelayout. I completely missed its purposed. There are many tutorials on the map, who exactly state that framelayouts are only for displaying one element, which is quite confusing (http://www.learn-android.com/2010/01/05/android-layout-tutorial/3/: "FrameLayout is designed to display a single item at a time. " ,...)

A linear layout is more than sufficient for your problem :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"<!-- put the title of the wizard -->
android:layout_height="fill_parent">
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content" android:id="@+id/title"/>
<!-- the contents, image for this example, can be anything -->
<ImageView android:layout_width="fill_parent"
android:layout_height="0dip" android:layout_weight="1"
android:id="@+id/contents"/>
<!-- The navigation buttons -->
<LinearLayout android:layout_width="fill_parent"<Button android:layout_width="wrap_content"
android:layout_height="wrap_content" android:orientation="horizontal">
android:layout_height="wrap_content" android:text="prev"/>
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="next"/>
</LinearLayout>
</LinearLayout>
Hope it helps :)
