            private EmployeePresenter employeePresenter;
            Response<ArrayPOJO> response;
            public RecyclerView recyclerView;
            public ArrayList<EmployeePojo> employeetList = new ArrayList<>();
            public EmployeeAdapter empAdapter;
            public EmployeePojo employeePojo;

            @Override
            public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                     Bundle savedInstanceState) {

                view = inflater.inflate(R.layout.fragment_employee, container, false);

                Employees employees = new Employees();
                employeePresenter = new EmployeeDetailsImpl(employees);

                recyclerView = view.findViewById(R.id.recycler_view);

                RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getActivity());
                recyclerView.setLayoutManager(mLayoutManager);
                recyclerView.setItemAnimator(new DefaultItemAnimator());
                recyclerView.setAdapter(empAdapter);

                empDetails();
                return view;
            }

            private void empDetails() {

                employeePresenter.employeeDetails();
            }



            @Override
            public void onSuccessResponseView(Response<POJO> response, String type) {

            }



            @Override
            public void onSuccessResponseArrayView(Response<ArrayPOJO> response, String type) {

                ArrayPOJO empPojoresp = response.body();

                List<POJO> arrayPOJO = empPojoresp.getDetails();

                for (POJO pojo : arrayPOJO) {
                    employeePojo = new EmployeePojo(pojo.getId(), pojo.getMobile(), pojo.getName(), pojo.getIMAGE());
                    employeetList.add(employeePojo);
                }

                recyclerView.setAdapter(new EmployeeAdapter(getActivity(), employeetList));


                empAdapter.notifyDataSetChanged();
            }

        }

请修改以下代码

 Employees employees = new Employees();
 employeePresenter = new EmployeeDetailsImpl(employees);

到

 employeePresenter = new EmployeeDetailsImpl(this);

因为您正在为同一个 fragment 创建另一个实例
