Add a footerview to a Tab host Android

Question

I would like to add a footer view, a counter of the elements loaded in a list view. I would like to know where sholuld i put the footer view. I've already one in my listview and i suppose that i must not put it there because i want it vissible all the time, not when i get to the bottom of it like the one i have.

Code:

ListView:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     android:orientation="vertical">

<ListView
    android:id="@+id/lista"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:stackFromBottom="false"
    android:transcriptMode="normal"
    />
</LinearLayout>

Code of the tabs:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainTabActivity" >
<TabHost
    android:id="@android:id/tabhost"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentLeft="true"

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >
        <TabWidget

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="match_parent"
            android:layout_height="match_parent" >
            <LinearLayout
                android:id="@+id/tab1"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical" >                   
                <ListView
                    android:id="@+id/lista"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:stackFromBottom="false"
                    android:transcriptMode="normal"
                    />
            </LinearLayout>
            <LinearLayout
                android:id="b"
            </LinearLayout>

            <LinearLayout
                android:id="c"
            </LinearLayout>                
            <LinearLayout
                android:id="d"
            </LinearLayout>                            
        </FrameLayout>

If you put the FrameLayout with match_parent width and height inside a LinearLayout all the content will hide out of the screen.

There are 2 forms to add that footer:

First, set the framelayout with this sizes:

<FrameLayout
        android:id="@android:id/tabcontent"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1">

Two, use a RelativeLayout and set all content bellow others and add the footer with layout_alignParentBottom = true if you want to add the footer above the content or bellow the last view if you want that the footer be with the content.
