title: Android Black Roboto font style
body: <p>I would like to apply Black Roboto on a specific TextView. I defined a style, but I don't know how to set Black Roboto ?</p>
  
  <p>In styles.xml file, I have this style:</p>
  
  <pre><code>&lt;style name="IntroTitle"&gt;
      &lt;item name="android:textSize"&gt;48sp&lt;/item&gt;
      &lt;item name="android:textStyle"&gt;normal&lt;/item&gt;
      &lt;item name="android:textAllCaps"&gt;true&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>in my layout.xml:</p>
  
  <pre><code>&lt;TextView
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:id="@+id/title"
      style="@style/IntroTitle"
      android:textColor="@android:color/white"
      android:text="@string/intro_title_screen_1"/&gt;
  </code></pre>
  
  <p>Thanks by advance</p>
