How to add an ActionBar above a TabWidget?

I am creating a custom bar above a TabHost. For some reason the custom bar does not appear above the TabHost, instead it is drawn behind it. Not sure why. Here is my XML:

<?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">

<!-- 
    <RelativeLayout android:layout_height="wrap_content" android:layout_width="match_parent" android:id="@+id/actionbarRelativeLayout">
        <ImageButton android:layout_height="wrap_content" android:layout_width="wrap_content" android:src="@drawable/icon" android:id="@+id/stocktwitsImageButton"></ImageButton>
        <ImageButton android:layout_height="wrap_content" android:layout_width="wrap_content" android:src="@drawable/icon" android:id="@+id/composeImageButton" android:layout_alignParentRight="true"></ImageButton>
    </RelativeLayout>
-->

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp">
        <TabWidget
            android:id="@android:id/tabs"开发者_如何学Python

            android:layout_height="wrap_content" />
        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:padding="5dp" />
    </LinearLayout>
</TabHost>

Do not use TabHost as the root of your layout. Put your TabHost inside a LinearLayout with orientation:vertical.

Then inside the LinearLayout and before the TabHost, you can put your ActionBar.
