                android:layout_margin="20dp"
                app:cardCornerRadius="24dp"
                android:elevation="8dp"
                android:padding="1dp">
                <android.support.constraint.ConstraintLayout

you cannot round the viewPager, you just need to create a rounded rectangle (or any desired shape) drawable and set it as a background for the parent layout for each child fragment of the viewPager.
