title: Android : Set fontFamily in TextAppearance not working
body: <p>I wanted to have a default Headline TextStyle with fonts, and every style(HeaderStyle, HeaderTwoStyle) inheriting should be able to display correct font, in case I wanted to override the font in Headline. But its not working...</p>
  
  <pre><code>&lt;style name="Headline1" parent="TextAppearance.AppCompat.Headline"&gt;
      &lt;item name="android:textSize"&gt;@dimen/font_28sp&lt;/item&gt;
      &lt;item name="android:fontFamily"&gt;sans-serif&lt;/item&gt;
      &lt;item name="android:textColor"&gt;@color/headline1&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="HeaderStyle"&gt;
      &lt;item name="android:layout_gravity"&gt;center_horizontal&lt;/item&gt;
      &lt;item name="android:gravity"&gt;center&lt;/item&gt;
      &lt;item name="android:textAppearance"&gt;@style/Headline1&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="HeaderTwoStyle"&gt;
      &lt;item name="android:layout_gravity"&gt;center_horizontal&lt;/item&gt;
      &lt;item name="android:gravity"&gt;center&lt;/item&gt;
      &lt;item name="android:textAppearance"&gt;@style/Headline1&lt;/item&gt;
  &lt;/style&gt;
