如何为一张物品购买一张卡片，而不是用数据库中的最后一个物品填充所有卡片？

Question

我有这个片段：

    public class AttractionsFragment extends Fragment {

        Context context;
        private View LocationView;
        private RecyclerView myLocationsRecycler;
        private DatabaseReference ModelRef;

        public AttractionsFragment() {
            // Required empty public constructor
        }

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);


        }

        @Override
        public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            // Inflate the layout for this fragment
            LocationView = inflater.inflate(R.layout.fragment_blank, container, false);


            myLocationsRecycler = LocationView.findViewById(R.id.cat_recycler);
            myLocationsRecycler.setLayoutManager(new LinearLayoutManager(getContext()));
            FirebaseApp.initializeApp(context);
            ModelRef = FirebaseDatabase.getInstance().getReference().child("attraction_list");


            return LocationView;
        }

        @Override
        public void onStart() {
            super.onStart();

            FirebaseRecyclerOptions<Model> options = new FirebaseRecyclerOptions.Builder<Model>()
                    .setQuery(ModelRef, Model.class)
                    .build();

            FirebaseRecyclerAdapter<Model, ModelViewHolder> adapter = new FirebaseRecyclerAdapter<Model, ModelViewHolder>(options) {
                @Override
                protected void onBindViewHolder(@NonNull final ModelViewHolder holder,  int position, @NonNull Model model) {


                    ModelRef.addValueEventListener(new ValueEventListener() {
                        @Override
                        public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                            for(DataSnapshot data: dataSnapshot.getChildren()){
                                String name = data.child("name").getValue().toString();
                                String image=data.child("image_link").getValue().toString();

                                holder.title.setText(name);
                                Picasso.get().load(image).into(holder.imageBg);


                     }
                    }
                    @Override
                    public void onCancelled(@NonNull DatabaseError databaseError) {

                    }
                });

            }

            @NonNull
            @Override
            public ModelViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int viewType) {
                View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.card_item_layout, viewGroup, false);
                return new ModelViewHolder(view);
            }
        };
        myLocationsRecycler.setAdapter(adapter);
        adapter.startListening();
    }


    public static class ModelViewHolder extends RecyclerView.ViewHolder {

        ImageView imageBg;
        TextView title;

        public ModelViewHolder(@NonNull View itemView) {
            super(itemView);
            title = itemView.findViewById(R.id.title);
            imageBg = itemView.findViewById(R.id.image);
        }

    }

}

这个数据库

{
  "attraction_list": {
    "01":{
       "name": "Eye of London",
       "image_link": "gs://for-tourists-by-tourists.appspot.com/images/eye_london.png",
       "full_description": "As iconic for London as the Eiffel Tower is to Paris, the Coca-Cola London Eye is a spectacular testament to modern Britain.

The gradual rotation in one of the 32 high-tech glass capsules takes approximately 30 minutes, offering breathtaking views of London and its famous landmarks. Whether it’s with family, friends or maybe a romantic Champagne Experience just for two, London Eye tickets are an integral part of any trip to London.

name”：“大笨钟”，    “ image_link”：“ gs：//for-tourists-by-tourists.appspot.com/images/big_ben.png”，    “ full_description”：“尽管在夏季休假期间向国会大厦（又名威斯敏斯特宫）进行游览是收费的，但所有人都可以使用，但是英国居民可以进行游览...” } }

在我的应用中，我所有的卡片都获得了标题为“大笨钟”和该图片的更新，请帮助我为每张卡片添加一个不同的物品。
奇怪的是，我只有四张牌（我应该如此）
