I have a LazyColumn list which holds user Items and I have populated the list Item view no issue on that, in here say I need to update a view from the Item like updating the user profile picture without updating the whole list but just making the item that needs to be changed and not as whole page refresh.

I am using Firestore Paging Adapter for loading a list of data and displaying it in RecyclerView. I set onClickListener on each item loaded and I would like to remove item from RecyclerView if it is pressed. How can I do that.
I get pressed item with
val pressedUserRealtion = getItem(adapterPosition)?.toObject(UserRelation::class.java)
and I would like to delete this item from my RecyclerView. I searched and couldn't find any method that would do that, I can't get the reference to list that contains loaded items. The only thing I can think of is setting the view visibility to GONE when user selects the item.
for realtime update, you can use FirestoreRecyclerAdapter
FirestoreRecyclerAdapter — binds a Query to a RecyclerView and
responds to all real-time events included items being added, removed,
moved, or changed. Best used with small result sets since all results
are loaded at once

I am using the android paging library to show a list of posts in the recycler view, my data source loads data from inMemory list which I add and remove from it then invalidate the data source to refresh the PagedListAdapter, everything is working well, but the problem is that when I scroll through pages, for example, page #5, and delete some item and call invalidate(), the data source will be re-initialized and will invoke the callbacks again, which re-loads the items in the recycler view, and jump to the first page.
The question is: How to refresh the items without jumping to the first page, and stick in the selected position?
Thanks.
Generally, I plan to use SwipeRefreshLayout and RecyclerView to implement Pull-To-Refresh list. After pulling the list to refresh the data, it seems that the original item position has been added one for refreshing widget. Since it is the position of the item that decides what kind of views should be drew or loaded, after refreshing, it was detected that the position of the same item was increased by 1, which directly leads to the IndexOutOfBoundException when I try to access the last item in the original list.
Is there any method that I can handle this position change so that the last item will be available without any exception?
In my app, when a user types something in a search box then a list gets filtered but the position of the list items gets changed. And due to this changed position when the user clicks on a list item, it results in unwanted activity. Because I have set events to the list items according to their position. Is there any parameter of the list items/row which remains same even after getting the list filtered?
I want to show a list of items when the user clicks an overlay item on a map. The user should be able to select any of these items and edit them. The list can have many items (more than that can fit in one active screen) therefore it needs to be scrollable.
You could do it with an activity with a transparent background, then launch that activity on top. From there you can make the list editable, by using a custom list adapter & updating the data contained within the adapter.
