title: Custom TextSize of BottomNavigationView support android
body: <p>I am trying to change the textSize of BottomNavigationView from android support library 25.0.0</p>
  
  <pre><code>&lt;android.support.design.widget.BottomNavigationView
          android:id="@+id/bottom_navigation_view"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:layout_alignParentBottom="true"
          android:background="@color/colorPrimaryDark"
          android:foregroundTint="@color/colorAccent"
          app:itemIconTint="@android:color/white"
          app:itemTextColor="@android:color/white"
          app:layout_anchor="@id/lyt_container"
          app:layout_anchorGravity="bottom"
          app:itemTextAppearance="@style/TextStyleBNV"
          app:menu="@menu/nav_menu" /&gt;
  
  &lt;style name="TextStyleBNV"&gt;
          &lt;item name="android:textSize"&gt;@dimen/twelve_sp&lt;/item&gt;
          &lt;item name="android:padding"&gt;0dp&lt;/item&gt;
          &lt;item name="textAllCaps"&gt;false&lt;/item&gt;
      &lt;/style&gt;
