java-初始化后将数据发送到片段

将数据发送到初始化选项卡时出现问题.在方法getData()中,我收到的适配器为null,recyclerview也为null.

TabOne one = new TabOne()
one.getData(populatedList)

错误是下一个=>

java.lang.NullPointerException: Attempt to invoke virtual method 'void OneAdapter.setData(java.util.List)' on a null object reference.

最好是通过捆绑发送数据包中的片段或其他任何想法.

我叫getData(),因为这里是来自API的响应.

public class TabOne extends Fragment {

        private Unbinder unbinder;

        @BindView(R.id.fab)
        FloaTingActionButton floaTingActionButton;

        @BindView(R.id.recycler_view_recycler)
        RecyclerView recyclerView;

        private OneAdapter oneAdapter;

        private List<Response> response = new ArrayList<>();

        @Nullable
        @Override
        public View onCreateView(@NonNull LayoutInflater inflater,@Nullable ViewGroup container,@Nullable Bundle savedInstanceStatE) {
            View view = inflater.inflate(R.layout.tab_one,container,falsE);
            unbinder = ButterKnife.bind(this,view);

            linearlayoutmanager linearlayoutmanager = new linearlayoutmanager(getContext());
            oneAdapter = new OneAdapter(getContext(),responsE);

            recyclerView.setLayoutManager(linearlayoutmanager);
            recyclerView.setAdapter(oneAdapter);

            return view;
        }

        public void getData(List<Response> responsE){
            oneAdapter.setData(responsE);
        }

        @Override
        public void onDestroyView() {
            super.onDestroyView();
            unbinder.unbind();
        }

    }

public class EventClass{

    private List<FILL IT WITH YOUR OBjeCT> populatedList;

    public EventClass(int populatedList) {
        this.populatedList= populatedList;
    }

    public int getPopulatedList() {
        return populatedList;
    }
}

TabOne one = new TabOne()
one.getData(populatedList)

EventBus.getDefault().postSticky(new EventClass(populatedList));

@Subscribe
public void onEvent(EventClass event) {
     oneAdapter.setData(event.getPopulatedList());
}

EventBus.getDefault().register(this);//add in onCreateView
//...
EventBus.getDefault().unregister(this);//add in onDestroyView
