title: Give text of selected tab a different color using ViewPagerIndicator
body: <p>I've tried to let the <a href="https://github.com/JakeWharton/Android-ViewPagerIndicator/blob/master/sample/src/com/viewpagerindicator/sample/SampleTabsStyled.java">SampleTabsStyled demo</a> from the <a href="https://github.com/JakeWharton/Android-ViewPagerIndicator">ViewPagerIndicator</a> change the color of the text of the currently selected tab without success.</p>
  
  <p>However, the <a href="https://github.com/JakeWharton/Android-ViewPagerIndicator/blob/master/sample/src/com/viewpagerindicator/sample/SampleTitlesStyledTheme.java">SampleTitlesStyledTheme demo</a> does change its text color when switching between titles/tabs.</p>
  
  <p>When looking inside the <a href="https://github.com/JakeWharton/Android-ViewPagerIndicator/blob/master/sample/res/values/styles.xml">styles xml</a>:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;resources&gt;
      ...
      &lt;style name="CustomTitlePageIndicator"&gt;
          &lt;item name="android:background"&gt;#18FF0000&lt;/item&gt;
          &lt;item name="footerColor"&gt;#FFAA2222&lt;/item&gt;
          &lt;item name="footerLineHeight"&gt;1dp&lt;/item&gt;
          &lt;item name="footerIndicatorHeight"&gt;3dp&lt;/item&gt;
          &lt;item name="footerIndicatorStyle"&gt;underline&lt;/item&gt;
          &lt;item name="android:textColor"&gt;#AA000000&lt;/item&gt;
          &lt;item name="selectedColor"&gt;#FF000000&lt;/item&gt;
          &lt;item name="selectedBold"&gt;true&lt;/item&gt;
      &lt;/style&gt;
      ...
      &lt;style name="CustomTabPageIndicator" parent="Widget.TabPageIndicator"&gt;
          &lt;item name="android:background"&gt;@drawable/custom_tab_indicator&lt;/item&gt;
          &lt;item name="android:textAppearance"&gt;@style/CustomTabPageIndicator.Text&lt;/item&gt;
          &lt;item name="android:textColor"&gt;#FF555555&lt;/item&gt;
          &lt;item name="android:textSize"&gt;16sp&lt;/item&gt;
          &lt;item name="android:divider"&gt;@drawable/custom_tab_indicator_divider&lt;/item&gt;
          &lt;item name="android:dividerPadding"&gt;10dp&lt;/item&gt;
          &lt;item name="android:showDividers"&gt;middle&lt;/item&gt;
          &lt;item name="android:paddingLeft"&gt;8dp&lt;/item&gt;
          &lt;item name="android:paddingRight"&gt;8dp&lt;/item&gt;
          &lt;item name="android:fadingEdge"&gt;horizontal&lt;/item&gt;
          &lt;item name="android:fadingEdgeLength"&gt;8dp&lt;/item&gt;
      &lt;/style&gt;
  
      &lt;style name="CustomTabPageIndicator.Text" parent="android:TextAppearance.Medium"&gt;
          &lt;item name="android:typeface"&gt;monospace&lt;/item&gt;
      &lt;/style&gt;
      ...
  &lt;/resources&gt;
  </code></pre>
  
  <p>I see that the <code>SampleTitlesStyledTheme</code> demo uses the <code>CustomTitlePageIndicator</code> style, which defines a <code>selectedColor</code> item. So (perhaps naively) I thought to add</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;item name="selectedColor"&gt;#FF000000&lt;/item&gt;
  </code></pre>
  
  <p>to the style the <code>SampleTabsStyled</code> demo is using, <code>CustomTabPageIndicator</code>, but, alas, that didn't work.</p>
  
  <p>The question seems obvious, but I'll ask anyway: is there a way (using the present styles xml) to let the currently selected text of a tab in the <code>SampleTabsStyled</code> demo have a different color than the other tabs? If so, how?</p>
  
  <h3>EDIT</h3>
  
  <p>Oh, and I'm using this in combination with ActionBarSherlock, in case that is important...</p>
