Transition between 2 recycler views having cards

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.

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
enter image description here
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.

How Do I Add Multiple CardView Layouts To A RecyclerView?

Here is a video of the behavior of the app that I am trying to explain just in case if you didn't understand my explanation of the problem. See the link below...
https://file.re/2021/09/14/2021-09-1405-16-22/
I am trying to develop an android app that has several card view layouts that will be displayed in one recycler view. I am not having much luck getting the recycler view to list the layouts like I want it to. I can add the first layout just fine, and then add the second layout just as long as the first card view layout exists in the recycler view. If it doesn't exists in the recycler view, and I try adding the second card view layout first by clicking on the button to add it a couple times, it will add it along with the first card view layout. Also, when trying to remove the card views from the layout they are not removing correctly. Here is what I have in my java code...
MainActivity.Java

ftocConverterLabelBtn = findViewById(R.id.add_f_to_c_converter_label_btn);
ftokConverterLabelBtn = findViewById(R.id.add_f_to_k_converter_label_btn);
ftocConverterLabelBtn.setOnClickListener(new View.OnClickListener() {
#Override

if (clicked) {
addConverterCard.add(new RecyclerItem());
recyclerView.setHasFixedSize(true);
layoutManager = new LinearLayoutManager(MainActivity.this);
recyclerItemAdapter = new RecyclerItemAdapter(addConverterCard);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(recyclerItemAdapter);
recyclerItemAdapter.notifyDataSetChanged();
closeActionButton();
}
}

well there's some mistakes I suspect so I will try and suggest some things maybe it fixes your code behavior.
in removing the card, consider using holder.getAbsoluteAdapterPosition() instead of viewHolder.getLayoutPosition() or getAdapterPosition.
on adding any card, stop creating a new Adapter and LayoutManager over and over again, this components should be created once for any RecylcerView, just keep a reference to only the first old created adapter as a global variable, add the new card to the data ArrayList that the old adapter has reference to, use adapter.notifyDataSetChanged() on the old adapter reference that you're keeping as global variable.
I don't know how the viewType algorithm works, but if the options from add button decide which one you want, store an index to which card you want in the RecyclerItem object itself and in getItemViewType that you're overriding get the item at the required position and return its stored type rather than this strange position calculation (position%2*2).
by doing that make switch cases according to the integer values that you will be storing in ftoc/ftok/...etcConverterLabelBtn.setOnClickListener.
that would be a solution that it doesn't add or delete the right type of card in correspondence to your add/delete choices since your viewType algorithm will return value based on just the position not your choice.
anytime I used setHasFixedSize(true) it caused me trouble, so if you don't have a good reason to be using this, I suggest that you delete/comment its line of code completely
Update
your code should be looking like this :
Main Activity
public class MainActivity extends AppCompatActivity {
ArrayList<RecyclerItem> addConverterCard ;
private RecyclerView recyclerView;
private RecyclerItemAdapter recyclerItemAdapter;
private RecyclerView.LayoutManager layoutManager;
public TextView ftocConverterLabelBtn, ftokConverterLabelBtn;

setContentView(R.layout.activity_main);

ftocConverterLabelBtn = findViewById(R.id.add_f_to_c_converter_label_btn);
ftokConverterLabelBtn = findViewById(R.id.add_f_to_k_converter_label_btn);
addConverterCard = new ArrayList<>();
recyclerItemAdapter = new RecyclerItemAdapter(addConverterCard);
layoutManager = new LinearLayoutManager(MainActivity.this);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(recyclerItemAdapter);
ftocConverterLabelBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (clicked) {
addConverterCard.add(new RecyclerItem(0));
recyclerItemAdapter.notifyDataSetChanged();
closeActionButton();
}
}
});
ftokConverterLabelBtn.setOnClickListener(new View.OnClickListener() {

Nested Recycler View, Child And Parent Remove Issue

I have created a Nested recycle rview with parent and child both dynamic.Addition to both Parent and Child is working fine.Deletion from child is working fine.I want to remove parent view when all the child views for the same is removed.Confused about how could i implement the same.
Here is the child Adapter

remove for child is working fine. How to remove Parent here when there are no more child views?

Well you can achieve this in many ways but i think sharedElementTransition will just do the thing for you
Use SharedElementTransition which make it easier as all the thing will be done by the android system itself you can reffer SharedElementTransition
Hope it Helped :)
