My Scrollview leaves space under some layouts ?

RelativeLayout under ConstraintLayout has android:layout_marginEnd="16dp"RecyclerView after RelativeLayout is closed, has android:layout_marginEnd="16dp"ConstraintLayout inside CardView has android:layout_marginBottom="16dp"LinearLayout inside last CardView has android:layout_marginBottom="16dp"Try altering them or removing them & see if it works. In my opinion, removing these 4 parameters should work.
