Good day. I am puzzled over how to implement the replace method (View v1, View v2) which should change two View on a fragment of the places that lie in the root of the constrait layout. Thanks in advance for your help.

    You need to work with the ConstraintSet class.

    Found an example of a similar question in English. stack

    But this article is better in Russian.

    The logic is as follows: Create ConstaintSet set = new ConstraintSet()

    You call it .clone(myConstraintLayout) then for specific views you call

     set.clear(view1, Constraint.PARAM)

    clear the reference to the viewpoint and assign it a new counterpart through

     set.connect()

    Then plug in the animation TransitionManager.beginDelayedTransition(myConstraintLayout);

    And in the end apply all changes to the layout

     set.applyTo(myConstraintLayout);
