How can I set the Background of all my activities in styles.xml

Question

I am trying to customize my styles.xml file to display the same background for each one of my activities.

I tried this code in my styles.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Theme.MyTheme" parent="android:Theme.NoTitleBar">
        <item name="android:background">@drawable/mybg</item>
    </style>
</resources>

this worked pretty well untill I put a TextView in my activity.. Every View I put in my layout get the same background, and that is really annoying

What is the best practice to set only the background of the activity?

I think I have found my answer:

 <item name="android:windowBackground">

fits all my needs

May be you can do it like this :

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="yourstylename">
    <item name="android:background">@drawable/mybg</item>
</style>

and set this style to all your activities root element in xml file.
