RecyclerList | Easy to use RecyclerView | RecyclerView library

This is the error im getting(This is a secondary error and I get this when I use databinding with ListItemView)

I have a recycler view where I fetch details from my database. An ArrayList of FriendEntity is given by the room database which works fine. I want to first have an unchecked box image for the whole list, and if I tap the image, it should change into a checked box image. But when I am achieving this, when I click on 1st item of recyclerView, my 16th item of recyclerView gets changed from unchecked to checked itself and the same goes with the 2nd and 17th, 3rd, and 18th and so on. I don't know if this is a problem with a recycler view adapter or something else.

Data Class FriendEntity :

setClickable() and setEnabled() aren't working but other methods like setVisibilty() working very well so what is supposed to happen is when starting action mode the recycler view should be disabled and non-clickable. i had searched the web for solutions but nothing of them were useful for me

fragment class

I'm trying to pass data from fragment to its viewHolder. My data is a String value. I will use this data in another activity when I clicked an item. I googled many times but can not find any solution. But I don't know how to do it. Here is my fragment and viewHolder If you want to know something else let me know.

I'm having troubles trying to display a recycler which contains more than 1 ViewHolder, i was testing and sending a custom List which contains only data to display a list of the 1st ViewType.

payments.add(Purchase(0,R.drawable.ic_cart,"","")) payments.add(Purchase(0,R.drawable.ic_favorite,"","")) payments.add(Purchase(0,R.drawable.ic_arrow_back,"",""))

This is the BottomSheetClass

I have a recyclerview which I show my values for users. But I need to show their own values to them.

First this is the code for GET values. (Working perfectly)

I'm using android navigation controller.

My main activity hosts a nav fragment but where should other components like toolbars and nav bottom bar go, in the main activity or child fragments?

activity_main.xml

I have been searching and found some close questions and answer but none of them works.

I'm using CoordinatorLayout for a list RecyclerView with AppBarLayout and ToolBar.

My Goal:

The ideia is very simple, when you roll the view first the AppBar Collapse in the Toolbar and after that the RecyclerView start to scroll.

My Hierarchy:

My Fragment RecyclerView(vertical) has a Adapter-A with a new layout, and this adapter call a second adapter-B for the RecyclerView(horizontal).

So I Have a struct like this: (is not a code, just to show how works)

In my application I want use RecyclerView and for this I set multiple layout in RecyclerView.
I changed layouts with button in fragment with below codes:
