Change the background of all the activities in the app
<p>I'm trying to define a background as default for all the activities in the app. So I have used:</p>

<pre><code>&lt;style name="testStyle" parent="@android:style/Theme.NoTitleBar"&gt;
    &lt;item name="android:background"&gt;@color/app_background_color&lt;/item&gt;
&lt;/style&gt;
</code></pre>

<p>and then in the manifest </p>

<pre><code>&lt;application
    android:icon="@drawable/icon"
    android:theme="@style/testStyle" 
    .....
</code></pre>

<p>But that way the background is applied to other elements like Dialogs title and Toasts backgrounds. How can I make that style only affect the background of the activities?</p>

<p>Thanks</p>
