Android : scroll view causing issue while displaying

Issue

I have a constraint layout which has 2 child's , the top most is the cardView (androidX) and the next one is the scrollView.

Normally it work's fine , but when the scroll view has to many children's (like the one shown below) the view's start causing issues. I can't seem to scroll to the top most child of scroll view nor the bottom most.

Thing's i have tried are :

1. Change card view to linearLayout (doesn't solve the issue)
2. add android:layout_marginTop="180dp" to the scroll view (hide's the last few child's)
3. change the constraints to point to parent for scroll view (caused cardview to overlap on top of scrollview)

---

I want the scroll view to start just below the card view and all it's children's should be visible no matter the child count.

How can i achieve this??
