title: Android - Change Actionbar Title Text Color
body: <p>I'm developing an app and I want to <code>change the textcolor of the actionbar title</code>. now, I defined a theme in my manifest:</p>
  
  <pre><code>&lt;application
          android:theme="@style/AppTheme"&gt;
  &lt;/application&gt;
  </code></pre>
  
  <p>which is defined in styles.xml:</p>
  
  <pre><code>&lt;style name="AppTheme" parent="android:style/Theme.Holo.Light"&gt;
          &lt;item name="android:textViewStyle"&gt;@style/AppTheme.TextView&lt;/item&gt;
          &lt;item name="android:actionBarStyle"&gt;@style/AppTheme.ActionBarStyle&lt;/item&gt;
      &lt;/style&gt;
  
      &lt;style name="AppTheme.ActionBarStyle" parent="@android:style/Widget.Holo.Light.ActionBar"&gt;
          &lt;item name="android:titleTextStyle"&gt;@style/AppTheme.ActionBar.TitleTextStyle&lt;/item&gt;
      &lt;/style&gt;
  
      &lt;style name="AppTheme.ActionBar.TitleTextStyle" parent="@android:style/TextAppearance.Holo.Widget.ActionBar.Title"&gt;
          &lt;item name="android:textColor"&gt;@color/themeapp&lt;/item&gt;
      &lt;/style&gt;
  
      &lt;style name="AppTheme.TextView" parent="@android:style/Widget.TextView"&gt;
          &lt;item name="android:textColor"&gt;#FFFFFF&lt;/item&gt;
      &lt;/style&gt;
  </code></pre>
  
  <p>this doesn't work but I don't get why. this should work according to <a href="https://stackoverflow.com/a/5881739/2139586">this answer</a>.neither the textview style is working.</p>
  
  <p>what I am doing wrong?</p>
