I have 2 recycler views that have cards.They basically look the same have the same number of cards and everthing. The first one is for like viewing and other stuff and the second one is only for deleting cards. OnlongClicking a card in the first recycler view triggers the opening of the second recycler view. I wanted to add transitions in between them like what keep notes has done when a card is long clicked. Both the recycler view use the same adapter. I have set what the adapter should do based on passing context to the adapter. enter image description here this is my 1st layout having the 1st recycler view.enter image description here this is the 2nd layout having the second recycler view.I want like a seamless transition for the tool bar again just like what Google keeps has done.A simple solution would be preferred as I am very new to this stuff.
Here is the java code for the adapter.
public class Task_recycle_view_adapter extends RecyclerView.Adapter<Task_recycle_view_adapter.ViewHolder>{

I have added the code related to the scene transititon which is in the adapter.
here is a gif of the problem when i add a scene transition
As u can see there are 2 pauses when going from 1st to 2nd activity 1st pause being longer 2nd one shorter. And also a pause when exiting the 2nd activity which seems to have the same duration as the 2nd pause.
