ActionBarSherlock - actionbar custom background with divider

Question

I'm implementing ActionBarsherlock and I want to change the actionbar background.

I override the properties but the blue divider dissapear. How can I use custom background with the blue divider?

<style name="Theme.MyTheme" parent="Theme.Sherlock.ForceOverflow">
    <item name="actionBarStyle">@style/Widget.MyTheme.ActionBar</item>
    <item name="android:actionBarStyle">@style/Widget.MyTheme.ActionBar</item>
</style>

<style name="Widget.MyTheme.ActionBar" parent="Widget.Sherlock.ActionBar">
    <item name="android:background">#ff3e3f3d</item>
    <item name="background">#ff3e3f3d</item>
</style>

For anyone who (like me) doesn't enjoy playing around with 9-patch images, you can get the divider at the bottom of the action bar using an xml drawable:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Bottom Line -->
    <item>
        <shape android:shape="rectangle">
            <solid android:color="@color/action_bar_line_color" />
        </shape>
    </item>

    <!-- Color of your action bar -->
    <item android:bottom="2dip">
        <shape android:shape="rectangle">
            <solid android:color="@color/action_bar_color" />
        </shape>
    </item>
</layer-list>

Save this as drawable/action_bar_background.xml, Then apply it in your theme:

<style name="Widget.MyTheme.ActionBar" parent="Widget.Sherlock.ActionBar">
    <item name="android:background">@drawable/action_bar_background</item>
    <item name="background">@drawable/action_bar_background</item>
</style>
