LayoutTo not changing bounds of views

I'm trying to change the position of children in a RelativeLayout with LayoutTo(), the animation works fine but any actions on the views after this reset the view to original constraints. I'm looking for a way to update the constraints of the view, TranslateTo can be used to update the constraints but this can only be used to update the position, not the width or height.

What seems to be the same problem:

Any solution or workaround to this problem?
