调用片段并在RecyclerView适配器中获取id

Question

我有一个使用RecyclerView的列表，我想要的是，当我点击列表项时，它会打开一个片段，我一直在搜索，我只在一个活动中找到了它，但我只在片段中工作，如果我使用活动，它会随着我的操作栏消失，它都在片段中设置。

这是我的适配器类：

    public class CreditCardAdapter extends RecyclerView.Adapter<CreditCardHolder> {

    private final List<CreditCard> creditList;

    public CreditCardAdapter(List<CreditCard> creditList) {
        this.creditList = creditList;
    }

    @NonNull
    @Override
    public CreditCardHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.credit_card_item, parent, false);
        return new CreditCardHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull CreditCardHolder holder, int position) {
        CreditCard credit = creditList.get(position);
        String flag = credit.getFlag();
        holder.flag.setText(flag);
        String owner = credit.getOwner();
        holder.owner.setText(owner);
        String valueLimit = String.format("%.2f", credit.getLimit());
        holder.limit.setText(valueLimit.replace(".", ","));
        holder.creditCardId = credit.getId();

        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
               //Method on click
            }
        });
    }


    @Override
    public int getItemCount() {
        return creditList.size();
    }
}

我需要将信用卡id发送到片段，调用控制器并从数据库中获取信息，我尝试了使用intent，但只有在使用startActivity（intent）调用活动时才有效。

这里是片段类：

public class InfoCreditCardFragment extends Fragment {

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


        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_info_credit_card, container, false);


        String id; //Here I need the id from the Adapter

        TextView flagInfoTxt = view.findViewById(R.id.flagInfoTxt);
        TextView ownerInfoTxt = view.findViewById(R.id.ownerInfoTxt);

        CreditCard cc = CreditCardController.getWithId(id);
        flagInfoTxt.setText(cc.getFlag());
        ownerInfoTxt.setText(cc.getOwner());


        return view;
    }
}

如果有人知道什么可以帮忙的，拜托，我已经绝望了。

Answer 1

因此，我使用以下方法找到了片段：

Bundle bundle = new Bundle();
bundle.putString("id", holder.creditCardId);

InfoCreditCardFragment fragment = new InfoCreditCardFragment();
AppCompatActivity activity = (AppCompatActivity) view.getContext();
activity.getSupportFragmentManager().beginTransaction().replace(R.id.fragmentContainer, fragment).addToBackStack(null).commit();

在片段中，我只得到带有“getArguments（）”的捆绑包。getString（“id”）；"
