Android Black Roboto font style

Question

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 ?

In styles.xml file, I have this style:

<style name="IntroTitle">
    <item name="android:textSize">48sp</item>
    <item name="android:textStyle">normal</item>
    <item name="android:textAllCaps">true</item>
</style>

in my layout.xml:

<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"/>

Thanks by advance
