title: Font is not applying on CheckBox and Switch Android Studio 3
body: <p>After updating to Android Studio 3 and using the latest SDK and build tools there is a feature to add fonts to the <code>fonts</code> folder under resources and use it directly in xml or java. I'm using this code in my theme in <code>styles.xml</code> to apply theme on my whole application</p>
  
  <pre><code>&lt;item name="android:fontFamily"&gt;@font/iransansfont&lt;/item&gt;
  </code></pre>
  
  <p>it's working on <code>Button</code>, <code>TextView</code>, and pretty much everything except <code>CheckBox</code> and <code>Switch</code> widgets. I even tried <code>fontFamily</code> on my <code>CheckBox</code>s and <code>Switch</code>s but it's not working either. How can i fix it?</p>
