Answer 1

if you want a shadow effect for an image view. Then ad these lines of code for your image view:

    android:elevation="25dp"
    android:outlineProvider="bounds"

if you want a shadow effect for Card view. Then ad these lines of code for your Card view:

app:cardElevation="15dp"
app:cardCornerRadius="8dp"
