title: Android: Title Bar Color don't change
body: <p>I wanna change my Apps Titlebar color and tried it in this way:</p>
  
  <p>Part of the manifest file:</p>
  
  <pre><code>&lt;application
          android:icon="@drawable/icon"
          android:label="@string/app_name"  
          android:theme="@style/Theme.MyTitleBar" &gt;&lt;/application&gt;
  </code></pre>
  
  <p>The style block part of the file styles.xml:</p>
  
  <pre><code> &lt;style name="Theme.MyTitleBar" parent="android:Theme"&gt;
          &lt;item name="android:colorBackground"&gt;#FFFFFF&lt;/item&gt;
          &lt;item name="android:background"&gt;#FFFFFF&lt;/item&gt;
          &lt;item name="android:textColor"&gt;@android:color/black&lt;/item&gt;
          &lt;item name="android:textStyle"&gt;bold&lt;/item&gt;
          &lt;item name="android:textSize"&gt;16sp&lt;/item&gt;
   &lt;/style&gt;
  </code></pre>
  
  <p>But only the text color and attributes changes correct. Any guest what I did wrong?</p>
