Hi Jorge Aguilar, I tried the codes, the animation still as per what I had with my approach of Constraint Layout assigned (i.e. the animation result that is not right). I don’t see any reason
layout_height="0dp” and top-bottom constraint are the cause and required for the animation to work. The Constraint Layout XML I made, is done using the Design Layout.
If you could provide a git repo with your constraint layout and working example, that would help much. I welcome alternative way that still achieve what is intended.
