无法删除recyclerview项目

Question

In my recylerview item, there is an option to delete the item. I am trying to achieve it in this way from activity class :

list.remove(position);
recyclerView.removeViewAt(position);
adapter.notifyItemRemoved(position);
adapter.notifyItemRangeChanged(position, list.size());

But I am getting the following error :

java.lang.NoSuchMethodError: No virtual method notifyItemRemoved(I)V in class RecyclerviewAdapter

What is wrong here?

Answer 1

Do not try to remove it by getting a position in Recycler view. Please refer any unique id or unique attribute of that element for it. If there are no unique elements in your objects in recycling view, please add the unique id.

Then get unique id when the user clicks an item in recycle view. After that search through whole the list and delete a relevant item from a list using a unique id
