The error states clearly. Inside history_list_details_fragment.xml there is no Toolbar. Try to add it.
Or more probably the Toolbar is in you Activity layout, so init it inside Activity.

Shared elements in fragments dont work, textview -> edittext

I have 2 fragments, and want to do a shared element transition between them.
The item in an recyclerview, with an adapter, contains a textview that should be animated to an edittext in the next fragment.
The recyclerview is in an fragment too.
Here's my code:

The textview doesnt animate to an edittext.
The explode animation appears.
Between activities the animation works.
Any suggestions how to fix?
