Create a LinearLayout with the orientation set to vertical and set that as your content view. Then add the Cover flow view and the list view to the layout.
If you do it in a layout xml it would be something like this (change the "com.example.package" to the pckage where your CoverFlow is located):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<com.example.package.CoverFlow
android:id="@+id/cover_flow"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<ListView
android:id="@+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
