SharedTransition | 在5.0以下版本实现界面之间共享元素动画

I'm using api to get the data and When i press the back button from UserProfileActivity and return to ImageViewerActivty I'am getting this error, I've searched through StackOverflow but couldn't find a solution it'd be great if someone could point me towards the solution.

//UserProfileActivity

So I've read all the articles and examples on sharedTransitions I could find and it seemed simple enough, but for some reason it doesn't work for me.

This is my RecyclerView.Item layout:

Background

I am trying to implement the "parent-to-child" navigational transition specifically when you click a Recyclerview entry and the details appear in a fullscreen fragment. Something like this:

Question

How do I go about doing this with so many animation APIs available? (TransitionManager.beginDelayedTransition, SharedTransition, setExitTransition, etc)

What I have tried

• InboxRecyclerView - This matches my requirements EXCEPT that it seems to only work when the detail view is in the same layout as the Recyclerview. Because I am navigating between fragments using the fragment backstack, I need it to transition between layouts that might not be available prior to attachment.

• This post - Answers only cover activity-to-activity transitions. I am looking for fragment-to-fragment.

• Custom Transition - I tried extending the Transition class, but I ran into the problems. CaptureStartValues() seems to capture values from the entire scene. I need it to only capture values from the recyclerview entry. Also, for some reason, the end values are not captured seeing as I get null endValues in the function createAnimator(ViewGroup sceneRoot, TransitionValues startValues, TransitionValues endValues).
