im试图从数据库检索数据到碎片使用回收视图，但我得到错误回收审查：没有适配器连接;跳过布局我试图在获取和获取上下文之间切换，但仍然没有解决任何问题搜索.javapackage com.example.lifetravel40;public class Search {private  int search_id;private String activity;private String description;private String activity_img;private String origin;private String destination;private String date_from;private String date_to;private String price ;public Search(String activity, String description, String activity_img, String origin, String destination, String date_from, String date_to, String price){    this.search_id = search_id;    this.activity = activity;    this.description = description;    this.activity_img = activity_img;    this.origin =origin;    this.destination = destination;    this.date_from = date_from;    this.date_to = date_to;    this.price = price;}public int getSearch_id(){    return search_id;}public String getActivity(){    return activity;}public String getDescription(){    return description;}public String getActivity_img(){    return activity_img;}public String getOrigin(){    return origin;}public String getDestination(){    return destination;}public String getDate_from(){    return date_from;}public String getDate_to(){    return date_to;}public String getPrice(){    return price;}  }

Answer 1

尝试将 空设置为adapterrecyclerViewonCreateView()

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

                         Bundle savedInstanceState) {

    // Inflate the layout for this fragment

    View v = inflater.inflate(R.layout.fragment_redirect, container, false);

    recylcerView =(RecyclerView) v.findViewById(R.id.recyclerView);

    LinearLayoutManager manager = new LinearLayoutManager(getContext());

    recylcerView.setLayoutManager(manager);

    recylcerView.setHasFixedSize(true);

    searchList = new ArrayList<>();

    List<Search> searchList = new ArrayList<>()

    SearchAdapter adapter1 = new SearchAdapter(getContext(),searchList);

    recylcerView.setAdapter(adapter1);

    loadSearch();

    return v;

}

然后在您向呼叫中添加新项时作为响应searchListadapter1.notifyDataSetChanged()

尝试更改

public class redirectFragment <recyclerView> extends Fragment

进入这个

public class redirectFragment extends Fragment
