                android:layout_height="wrap_content"               
                android:text="ABC"               
                android:textSize="16sp"
                app:typeface="robotoBlack" />

Answer 1

The Typeface class specifies the typeface and intrinsic style of a font.

You should call android:typeface instead of typeface .

Don't

<item name="typeface">robotoRegular</item>

Do

<item name="android:typeface">robotoRegular</item>

Answer 2

you should use android:typeface,not typeface.
