  <p>However, the text size is big and I want to change it. For this I set custom style in <code>style.xml</code>, but it does not change the text size.</p>
  
  <p><strong>XML Code:</strong> </p>
  
  <pre><code>&lt;cn.mycommons.tablayoutplus.library.TabLayoutPlus
      android:id="@+id/fullSearch_tabLayout"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_below="@+id/fullSearch_toolbar"
      android:background="@color/colorPrimary"
      android:paddingBottom="@dimen/size2"
      android:paddingLeft="@dimen/size2"
      android:paddingRight="@dimen/size2"
      app:tabIndicatorColor="@color/whiteMe"
      app:tabSelectedTextColor="@color/whiteMe"
      app:tabTextAppearance="@style/allCapsTabLayout_search"
      app:tabTextColor="@color/unSelectTab" /&gt;
  
  
  &lt;style name="allCapsTabLayout_search" parent="TextAppearance.Design.Tab"&gt;
      &lt;item name="textAllCaps"&gt;false&lt;/item&gt;
      &lt;item name="android:textAllCaps"&gt;false&lt;/item&gt;
      &lt;item name="android:fontFamily"&gt;sans-serif&lt;/item&gt;
      &lt;item name="android:textSize"&gt;@dimen/font5&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>How can I change text size?</p>
