Şu anda bir kullanıcı ADD düğmesine dokunduğunda, n öğesine dokunan öğenin kalıcı olarak kaldırılması gerektiğini belirten firebase RecyclerView yardımı ile Arkadaşlarıma Ekleme üzerinde çalışıyorum. biz kaldırmak herhangi bir veri listesi yok gibi. bu yüzden, nasıl Firebase modeli yoluyla bunu başarmak için .. İşte Firebase'deki öğeler nasıl kaldırılır RecyclerView
