Android 共享元素转换在棉花糖中不起作用

我在棒棒糖中使用了共享元素转换，但现在我的手机升级到棉花糖，转换不再正常工作。从“活动A”到“活动B”的转换按预期工作，但当按“后退”返回到“活动A”时，转换工作，然后两个共享元素视图在屏幕外动画显示

活动A：

Intent flashcardIntent = new Intent(this, FlashcardActivity.class);
        flashcardIntent.putExtra(getString(R.string.study_id), flashcardSetId.toString());
        flashcardIntent.putExtra(getString(R.string.flashcard_calling_activity), FlashcardActivity.SUBJECT_LIST);
        ArrayList<Pair<View, String>> sharedElements = new ArrayList<>();
        sharedElements.add(new Pair<View, String>(titleView, getString(R.string.transition_set_title)));
        sharedElements.add(new Pair<View, String>(toolBar, getString(R.string.transition_toolbar)));
        FlashcardSet set = FlashcardSetService.getInstance().getFlashcardSet(flashcardSetId);
        if( set.isQuizletSet() )
        {
            sharedElements.add(new Pair<View, String>(quizletImage, getString(R.string.transition_quizlet_image)));
        }
        sharedElements.add(new Pair<View, String>(setCard, getString(R.string.transition_set_card)));
        sharedElements.add(new Pair<View, String>(cardCount, getString(R.string.transition_card_count)));
        ActivityOptionsCompat options = ActivityOptionsCompat.makeSceneTransitionAnimation(
                // the context of the activity
                this,
                // For each shared element, add to this method a new Pair item,
                // which contains the reference of the view we are transitioning *from*,
                // and the value of the transitionName attribute
                sharedElements.toArray(new Pair[sharedElements.size()])
        );

        ActivityCompat.startActivity(MainFlashcardSetListActivity.this, flashcardIntent, options.toBundle());

Intent flashcardIntent=新的Intent（这是FlashcardActivity.class）；
FlashCardContent.putExtra（getString（R.string.study_id）、flashcardSetId.toString（））；
FlashCardContent.putExtra（getString（R.string.flashcard\u calling\u activity）、FlashcardActivity.SUBJECT\u LIST）；
ArrayList sharedElements=新的ArrayList（）；
添加（新对（titleView，getString（R.string.transition\u set\u title））；
添加（新的一对（工具栏，getString（R.string.transition\u工具栏））；
FlashcardSet=FlashcardSetService.getInstance（）.getFlashcardSet（flashcardSetId）；
if（set.isQuizletSet（））
{
添加（新对（quizletImage，getString（R.string.transition\u quizlet\u image））；
}
添加（新对（setCard，getString（R.string.transition\u set\u card））；
添加（新对（cardCount、getString（R.string.transition\u card\u count））；
ActivityOptions Compat options=ActivityOptions Compat.MakeScenetTransitionAnimation(
//活动的背景
这
//对于每个共享元素，在此方法中添加一个新的Pair项，
//其中包含我们从*转换*的视图的引用，
//以及transitionName属性的值
sharedElements.toArray（新对[sharedElements.size（）]）
);
ActivityCompat.startActivity（MainFlashcardSetListActivity.this、FlashCardContent、options.toBundle（））；

有人遇到过这种行为吗？或者注意到代码有问题
