Я прошел половину Интернета и перепробовал все возможные переходы, и я не могу получить тот же эффект, что whatsapp делает с группой изображений (когда их 4).

Я делаю это с androidx, я не думаю, что в этом проблема.

Что я хочу: пример Whatsapp

То, что я нашел, но не работает для меня, потому что они связаны с деятельностью: Пример деятельности

Мой эффект: Мой эффект не работает

ФРАГМЕНТ А (щелчок держателя):

 // imageView is the view inside of itemView of viewholder in chat, view is the viewholder
private void openMediaListWithTransition(ImageView imageView, int imagePosition, int messagePosition, View view) {
    String transitionName = imageView.getTransitionName();
    ImageListFragment imageListFragment = ImageListFragment.newInstance(requireContext(),
            ((ChatAdapter.MessageMultiMedia) adapter.getMessageAt(
                    messagePosition)).getMessages(), imagePosition, messagePosition, "TRANSITION");

    //imageListFragment.setEnterTransition(new Fade());

    //imageListFragment.setEnterTransition(new Fade());
