Android Constraint Layout inside Scrollview inside Constraint Layout

I'm my search the closest question was that: Scrollview inside constraint layout does not scroll to the bottom of the parent constraint

But there is no solution =|.

What I'm trying to do:

I have a constraint layout with 3 "parts": top bar, middle content and bottom button.

I want to put a scrollview only for the middle content. So if you scroll down and up you continuous to see the top bar and the bottom button

But this scroll view is not working, I think is something related with "match_parent" in the scrollview, but I can't put this option because as the scrollview is inside a Constraint Layout the size should be relative and if I put match parent it don't fill all spaces.

I'm using already: fillViewport="true", layout_constraintBottom_toBottomOf="parent"

Follow the code, scroll view name: "scrollview2"

You need to create a chain with the following constraints

  • in the top bar:

    app:layout_constraintBottom_toTopOf="@+id/scrollView2" app:layout_constraintTop_toTopOf="parent"

  • in the middle content:

    app:layout_constraintBottom_toTopOf="@+id/needs_search_save_btn" app:layout_constraintTop_toBottomOf="@+id/actionbar"

  • in the bottom button:

    app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintTop_toBottomOf="@+id/scrollView2"

Well, I just found the solution with a friend, first I think about delete this, but since other people maybe have the same problem here is the solution:

I just remove all guidelines and build again, connecting the elements without using so many guidelines.

Was a little bit of lucky, because I did this to fix when change the orientation.
