I have a RecyclerView . I need to implement the removal, modification and addition of the item list (just TextView ). If everything is clear with the change - I just get and change the View , then how can I remove and add only one item without reloading the entire list?

    1. Add / remove an item to / from the list (s) of data displayed by the adapter.
    2. Call notifyItemInserted(int positionOfInsertedElement); / notifyItemRemoved(int positionOfRemovedElement); adapter method.

      Uh-uh ... Well ... The documentation assures that for this there are methods add & remove ... The classes that implement the List ... - JuriySPb ♦
    • Does the RecyclerView implement the sheet? O. About - user189127
    • Not. But the data that you transfer to the adapter may well be. If you have an array, then everything is more complicated (and almost impossible for me) - YuriiSPb ♦
