How to know when Shared Element Transition ends

Did you try to bind animation listener to the shared element view inside onMapSharedElements? ViewCompat.animate(view) will give you either a new or cached ViewPropertyAnimator(Compat) and then binding the animation listener should be trivial. I haven't tried it, though.

setEnterSharedElementCallback(new SharedElementCallback() {            @Override            public void onMapSharedElements(List<String> names, Map<String, View> sharedElements) {                super.onMapSharedElements(names, sharedElements);                View keySharedElementView = sharedElements.get("keySharedElement");                if(keySharedElementView != null){                    ViewCompat.animate(keySharedElementView).setListener(new ViewPropertyAnimatorListenerAdapter(){                        @Override                        public void onAnimationEnd(View view) {                            super.onAnimationEnd(view);                        }                    });                }            }        });

What about adding Transition.Listener to the shared element transition?

 Transition sharedElementEnterTransition = getWindow().getSharedElementEnterTransition(); sharedElementEnterTransition.addListener(new TransitionListenerAdapter() {         @Override          public void onTransitionEnd(android.support.transition.Transition transition) {                    super.onTransitionEnd(transition);           }      });

Please try onEnterAnimationComplete() callback on your activity.

I bet this is exactly what you ere looking for.

 @Override    public void onEnterAnimationComplete() {        super.onEnterAnimationComplete();    //your code     }

Here is what I do in a fragment:

Transition sharedElementEnterTransition = getActivity().getWindow().getSharedElementEnterTransition();    sharedElementEnterTransition.addListener(new Transition.TransitionListener() {        @Override        public void onTransitionStart(Transition transition) {        }        @Override        public void onTransitionEnd(Transition transition) {        }        @Override        public void onTransitionCancel(Transition transition) {        }        @Override        public void onTransitionPause(Transition transition) {        }        @Override        public void onTransitionResume(Transition transition) {        }    });
