尝试将 空设置为adapterrecyclerViewonCreateView()@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Bundle savedInstanceState) {&nbsp; &nbsp; // Inflate the layout for this fragment&nbsp; &nbsp; View v = inflater.inflate(R.layout.fragment_redirect, container, false);&nbsp; &nbsp; recylcerView =(RecyclerView) v.findViewById(R.id.recyclerView);&nbsp; &nbsp; LinearLayoutManager manager = new LinearLayoutManager(getContext());&nbsp; &nbsp; recylcerView.setLayoutManager(manager);&nbsp; &nbsp; recylcerView.setHasFixedSize(true);&nbsp; &nbsp; searchList = new ArrayList<>();&nbsp; &nbsp; List<Search> searchList = new ArrayList<>()&nbsp; &nbsp; SearchAdapter adapter1 = new SearchAdapter(getContext(),searchList);&nbsp; &nbsp; recylcerView.setAdapter(adapter1);&nbsp; &nbsp; loadSearch();&nbsp; &nbsp; return v;}然后在您向呼叫中添加新项时作为响应searchListadapter1.notifyDataSetChanged()
