Recyclerview Onclick在单击Cardview时将特定数据传递给活动 [英] Recyclerview Onclick passing specific data when click cardview into activity

问题描述

我想要做的是将数据从特定用户传递到另一个活动中，使用其用户ID作为唯一ID
它不断将相同的数据发送到其他活动中，我不知道该怎么做

What I'm trying to do is to pass a data from a specific user into another activity using it's userID as unique ID
It keeps send the same data into the other activity, I dont know how to do it

这是 Fragment_Home 的代码，在这里我用来从Firebase获取数据并将其填充到RecyclerView中，以及Onclick目前所在的位置.

This is code is for the Fragment_Home where I use to get data from Firebase and populate it into the RecyclerView, and where the Onclick is in at the moment.

public class FragmentRO_Home extends Fragment {

private Intent intent;
private DatabaseReference database;
RecyclerView recyclerView;
Recycler_View_Adapter adapter;
TextView TV_nodata;
private String uid;
private String nombre;
public FragmentRO_Home() {
    // Required empty public constructor    qwe
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_fragment_ro__home,container,false);
    database = FirebaseDatabase.getInstance().getReference();
    final List<Data> data = new ArrayList();

    TV_nodata = (TextView)view.findViewById(R.id.TV_result);
    recyclerView = (RecyclerView) view.findViewById(R.id.recyclerview);
    adapter = new Recycler_View_Adapter(data, getActivity());
    recyclerView.setAdapter(adapter);
    recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));

    fill_with_data();

这是我与recyclerview一起使用的onclick，并且可以使用.

This is the onclick which I'm using with recyclerview and it's functionable.

    recyclerView.addOnItemTouchListener(new CustomRVItemTouchListener(getActivity(), recyclerView, new RecyclerViewItemClickListener() {
        @Override
        public void onClick(View view, int position) {
            if (position == 0){
                intent = new Intent(getActivity(), ReportInformation.class);
                intent.putExtra("idData",uid);
                startActivity(intent);
            }else if (position == 1){
                intent = new Intent(getActivity(), ReportInformation.class);
                intent.putExtra("idData",uid);
                startActivity(intent);
            }else if (position == 2){
                intent = new Intent(getActivity(), ReportInformation.class);
                intent.putExtra("idData",uid);
                startActivity(intent);
            }else if (position == 3){
                intent = new Intent(getActivity(), ReportInformation.class);
                intent.putExtra("idData",uid);
                startActivity(intent);
            }else if (position == 5){
                intent = new Intent(getActivity(), ReportInformation.class);
                intent.putExtra("idData",uid);
                startActivity(intent);
            }
        }

        @Override
        public void onLongClick(View view, int position) {

        }
    }));
    return view;
}

这是我从Firebase中获取数据来填充recyclerview的方法.

public void fill_with_data() {
    database.child("data_home").addListenerForSingleValueEvent(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot d) {

            if (d.exists()) {
                List<Data> list = new ArrayList<>();
                for (DataSnapshot dataw : d.getChildren()) {
                    Data data = dataw.getValue(Data.class);
                    list.add(data);

                    uid = (data.usirayd);
                    nombre = (data.title);
                }
                for (Data data : list) {
                    adapter.insert(new Data(data.title, data.description, data.condition, data.time,data.usirayd));
                }
            }else {
                TV_nodata.setVisibility(View.VISIBLE);
            }
        }

        @Override
        public void onCancelled(DatabaseError databaseError) {

        }
    });
    recyclerView.setAdapter(adapter);
}

推荐答案

尝试此代码

 recyclerView.addOnItemTouchListener(new CustomRVItemTouchListener(getActivity(), recyclerView, new RecyclerViewItemClickListener() {
        @Override
        public void onClick(View view, int position) {

            if(data.size()>position){
              if (data.get(position)!= null){
                intent = new Intent(getActivity(), ReportInformation.class);
                intent.putExtra("idData",data.get(position).usirayd);
                startActivity(intent);
               }
            }
        }

        @Override
        public void onLongClick(View view, int position) {

        }
    }));
    return view;
}
