How to set the width of an android tab in XML layout?

I've seen this programmatic solution but am wondering how do do this in the XML file.. my goal is to have a set of tabs up top the use all available screen width. I can't see how to do that currently. Setting layout_width for the tabhost to fill_parent does not do the trick.

I added a horizontal scrollbar and set android:fillViewport="true".

When I use tabs, I normally just hide the tabwidget tag by setting android visibility as gone.

And add buttons to act as the tab buttons like 

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@android:id/tabhost" android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" 
        android:layout_height="fill_parent">       
        <FrameLayout android:id="@android:id/tabcontent" 
            android:layout_width="fill_parent" android:layout_height="0dip"
            android:layout_weight="1.0"/>
        <FrameLayout android:layout_width="fill_parent" 
            android:layout_height="wrap_content">
            <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" 
                android:layout_height="wrap_content"
                android:visibility="gone"/>
            <LinearLayout android:layout_width="fill_parent" 
                android:layout_height="64dip">
                <Button android:layout_height="fill_parent" android:layout_width="0dip" 
                    android:layout_weight="1.0"
                    android:background="@drawable/ic_tab_artists" 
                    android:id="@+id/artist_id" android:onClick="tabHandler"/>
                <Button android:layout_height="fill_parent" android:layout_width="0dip" 
                    android:layout_weight="1.0"
                    android:background="@drawable/ic_tab_artists" 
                    android:id="@+id/album_id" android:onClick="tabHandler"/>
                <Button android:layout_height="fill_parent" android:layout_width="0dip"     
                    android:layout_weight="1.0"
                    android:background="@drawable/ic_tab_artists" 
                    android:id="@+id/song_id" android:onClick="tabHandler"/>
            </LinearLayout> 
        </FrameLayout>
    </LinearLayout>
</TabHost>

and I add a button click handler

public void tabHandler(View target){
    artistButton.setSelected(false);
    albumButton.setSelected(false);
    songButton.setSelected(false);
    if(target.getId() == R.id.artist_id){
        tabHost.setCurrentTab(0);
        artistButton.setSelected(true);
    } else if(target.getId() == R.id.album_id){
        tabHost.setCurrentTab(1);
        albumButton.setSelected(true);
    } else if(target.getId() == R.id.song_id){
        tabHost.setCurrentTab(2);
        songButton.setSelected(true);
    }
}
