In Android Studio, text does not appear on top of an image



I’m doing a small project on Android Studio, and I’ve put a picture as a dark blue background. I inserted white text on top of this dark blue figure, but the white color in the letters still doesn’t show. The Graphical Interface. See that I put the color white, but it still doesn’t show up. Please, check out:

</androidx.constraintlayout.widget.ConstraintLayout>

Answer

Ok I think the problem is that you’ve set the foreground of the constraint layout instead of the background.

Try this:

 <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="410dp"
        android:layout_height="250dp"
        android:color="@color/white"
        android:background="@drawable/home_bg"
        android:textSize="30dp"
        android:textStyle="bold"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.0"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">
