Answer 1

Please add this to cardView

app:cardElevation="3dp"
app:cardCornerRadius="16dp"

Please remove this 2 line

app:cardPreventCornerOverlap="true"
app:cardUseCompatPadding="true"

And CardView will be Parent layout not ConstraintLayout so Please remove upper ConstraintLayout.

<com.google.android.material.card.MaterialCardView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_height="match_parent"
    android:layout_width="match_parent">
    
<androidx.constraintlayout.widget.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/AnyColor">

</androidx.constraintlayout.widget.ConstraintLayout>
</com.google.android.material.card.MaterialCardView>

I am sure after this it will show shadow and corner radius.
