Hi mọi người. mình có tạo 1 list add các Object  rồi add vào recyclerview. khi click trong recyclerview thì nó cập nhật dữ liệu lên chính object kia. có cách nào để clone hay copy ra 1 list object khác mà khi sửa dữ liệu ko ảnh hưởng đến dữ liệu của object ban đầu. mình cảm ơn

Trong cái đối tượng của em, em có thể thêm các trường temp, ví dụ: 

public class Data {
  String value;
  String valueTemp;
}

Rồi tương lai khi em muốn thay thế cái value bằng valueTemp, em chỉ cần set lại là được em ạ

e tìm đc 1 cách nữa là dùng làm .copy() khá gọn. về tư tưởng thì chắc cũng giống thế này mà bên kotlin hỗ trợ r  –  datnk 1632127951000
