title: Changing background android title bar
body: <p>I know this question has already been asked, but I can't figure out how to get it working. I want to change the background of my title bar.</p>
  
  <p>I don't want to change anything else about the style of my application or of my background.</p>
  
  <p>I followed various post on this site, but none of them seem to give a satisfying result.</p>
  
  <p>I would think it would be as simple as setting </p>
  
  <pre><code>&lt;style name="AppTheme" parent="AppBaseTheme"&gt;
  &lt;item name="android:windowTitleBackgroundStyle"&gt;@drawable/backrepeat&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>In styles.xml</p>
  
  <p>However this gives no change whatsover.</p>
  
  <p>For completness below is my backrepeat file</p>
  
  <pre><code>&lt;bitmap
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:src="@drawable/bg_diamonds"
  android:tileMode="repeat"
  android:dither="true" 
  /&gt;
  </code></pre>
  
  <p>and the code in manifest.xml</p>
  
  <pre><code>&lt;application
  android:allowBackup="true"
  android:icon="@drawable/maxmm_start_icon"
  android:label="@string/app_name"
  android:theme="@style/AppTheme" &gt;
  </code></pre>
