Change background color of ActionBarSherlock programmatically

Question

I have an ActionBarSherlock on my form. I'm reading style information at runtime. One of the pieces of style is the background color of the ActionBar. How can I change this at runtime? The color can be any RGB value.

Maybe this help : How to set title color in ActionBarSherlock? via style or getSupportActionBar().setBackgroundDrawable(getResources().getDrawable(R.drawable.ad_action_bar_gradient_bak)); via programmatically

With the theme

// add theme in app
<application android:theme="@style/MainTheme"></application>

// MainTheme
<style name="MainTheme" parent="Theme.Sherlock.Light.DarkActionBar">       
</style>

// MainThemeGreen
<style name="MainThemeGreen" parent="Theme.Sherlock.Light.DarkActionBar">
    <item name="android:actionBarStyle">@style/MainTheme.ActionBarStyle</item>        
</style>

// ActionBar
<style name="MainTheme.ActionBarStyle" parent="Widget.Sherlock.Light.ActionBar">
    <item name="android:background">@drawable/bg_green_actionbar</item>
    <item name="android:titleTextStyle">@style/MainTheme.ActionBar.TitleTextStyle</item>
</style>

// Text style
<style name="MainTheme.ActionBar.TitleTextStyle" parent="TextAppearance.Sherlock.Widget.ActionBar.Title">
    <item name="android:textColor">@color/White</item>
</style>

// bg_green_actionbar.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <shape>
            <solid android:color="#ff74af3b" />
        </shape>
    </item>
</layer-list>

After this you can change Theme on fly: setTheme(R.styles.MainThemeGreen);
