When I use the android:textFontWeight attribute on a TextView , it doesn't select the appropriate font from the font family. I tested it on API 28 , because the attribute is only available on 28+

<TextView
    android:id="@+id/text_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:fontFamily="@font/myfont"
    android:text="Hello World!" />
The myfont font-family is defined like this:
<font-family xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
    app:fontStyle="normal"
    app:fontWeight="400"
    app:font="@font/myfont_regular" />
    app:fontStyle="normal"
    app:fontWeight="200"
    app:font="@font/myfont_thin" />
