Hi, how to remove item at specific position in RecyclerView using paging library 3?

I assume that you expose some kind of onClick listener that’d execute that remove logic.

For instance a lambda which takes the itemId:
(String) -> Unit

Then delegate that action to your ViewModel ( assuming you use MVVM ), and use the filter operator the PagingData<T> to return a new PagingData without that ID.

Additionally if you use room or any kind of other local persistence, and you get your Paging<T> from a local source then just delete that item in the local persistence. ( assuming you expose a observable from the local persistence )

Yes but next time i clicked on item second time but its position is wrong

How do you keep track of the position, if the 2nd time it doesn’t work that means you have a stale dataset.

Instead of the position try using an ID, but still look into this ☝️

When i refresh list then its create problem with position
