ListView obscuring sibling views?

I can't seem to get the footer navigation bar to show up in this layout. It's obscured by the ListView no matter how I set layout_weight on the navigation bar or change the layout_height of the ListView to one of FILL_PARENT or WRAP_CONTENT. Any ideas how to get the correct result? Essentially, I want the footer to be fixed at the bottom of the screen.

(BTW, I need to keep the nested LinearLayouts. However, I can change them to other ViewGroups.)

<LinearLayout
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   android:orientation="vertical">
  <LinearLayout
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:orientation="vertical">
     <ListView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"/>
 <include layout="@layout/wizard_navbar_last" />
  </LinearLayout>
</LinearLayout>

Update: and I should point out that I'm actually adding the ListView via code like so:

ViewGroup page3 = (ViewGroup) 
    findViewById(R.id.wizard_page3_container); //parent linearlayout
page3 = (ViewGroup) page3.getChildAt(0); //linearlayout
LayoutInflater inflater=
    (LayoutInflater) LayoutInflater.from(getApplicationContext());
folderList = (ListView) inflater.inflate(R.layout.wizard_dropbox_list,
                     null);
page3.addView(folderList, 0);

Update2: the XML for the navbar:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/wizard_navbar_last"
  android:paddingTop="20dp"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:layout_weight="1"
  android:orientation="horizontal">
  <include 
    layout="@layout/wizard_previous_button"/>
  <View 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    />
  <Button
     android:id="@+id/wizard_finish"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:text="Done"
     android:textSize="20dp"/>
  </Linear开发者_StackOverflowLayout>

And previous_button is ... you guessed it, just a button. As for wizard_dropbox_list, it's the ListView as shown here.

Try wrapping the Listview and Navbar in a RelativeLayout. Set the ListView to alignParentTop="true" and layout_height="wrap_content", and set the NavBar to alignParentBottom="true" and layout_height="wrap_conent". That should give you the effect you're looking for.
