title: PagerTabStrip with all captial letters
body: <p>I have a PagerTabStrip in my app and I put in Strings to the Tab,</p>
  
  <pre><code>titles = new String[]{
              "Tab1",
              "Tab2",
              "Tab3"
  
  };
  </code></pre>
  
  <p>so suppose only "T" here is capital, but I get all capital letters. </p>
  
  <p>I also tried to fix this by adding textAllCap to be false through the style in xml:</p>
  
  <pre><code> &lt;style name="viewPagerTitleStrip"&gt;
      &lt;item name="android:textColor"&gt;@color/LightGrey2&lt;/item&gt;
      &lt;item name="android:textSize"&gt;20sp&lt;/item&gt;
      &lt;item name="android:textAllCaps"&gt;false&lt;/item&gt;
   &lt;/style&gt;
  </code></pre>
  
  <p>and then apply it in the layout xml:</p>
  
  <pre><code>&lt;android.support.v4.view.ViewPager
      android:id="@+id/mainFragContainer"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      app:layout_behavior="@string/appbar_scrolling_view_behavior"&gt;
  
      &lt;android.support.v4.view.PagerTabStrip
          android:id="@+id/titleStrip"
          style="@style/viewPagerTitleStrip"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:background="@color/colorPrimary"
          android:paddingTop="10dp"
          app:tabIndicatorColor="@color/LightGrey"
          /&gt;
  
  &lt;/android.support.v4.view.ViewPager&gt;
  </code></pre>
  
  <p>But they still appear to be all cap, i.e. "TAB1" , "TAB2", "TAB3"</p>
  
  <p>Can anyone help?</p>
