title: Styling text on TabLayout
body: <p>I'm trying to style the new <code>TabLayout</code> from android design library.</p>
  
  <pre><code>&lt;style name="NavigationTab" parent="Widget.Design.TabLayout"&gt;
      &lt;item name="tabBackground"&gt;@drawable/background_tab&lt;/item&gt;
      &lt;item name="tabIndicatorColor"&gt;@color/blue&lt;/item&gt;
      &lt;item name="tabTextAppearance"&gt;@style/NavigationTabTextAppeareance&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>And the text is defined right here</p>
  
  <pre><code>&lt;style name="NavigationTabTextAppeareance" parent="TextAppearance.Design.Tab"&gt;
        &lt;item name="android:textColor"&gt;@color/primary_light&lt;/item&gt;
        &lt;item name="android:textSize"&gt;12sp&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>But the selected tab is always black, how can I change it?</p>
