Question

这是我的适配器代码，我想将数据传递给“ParticularFragment” 注意：ParticularFragment扩展了Fragment

public class TopicsAdapter extends RecyclerView.Adapter<TopicsAdapter.ViewHolder> {

    private Context context;
    private ArrayList<QuoteItems> itemList;

    public TopicsAdapter(Context context, ArrayList<QuoteItems> itemList) {
        this.context = context;
        this.itemList = itemList;
    }

    @Override
    public TopicsAdapter.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.adapter_topics_recycler_view_items, viewGroup, false);
        ViewHolder viewHolder = new ViewHolder(v);

        return viewHolder;
    }

    @Override
    public void onBindViewHolder(final TopicsAdapter.ViewHolder viewHolder, int i) {

        final QuoteItems quoteItems = itemList.get(i);
        viewHolder.txtQuote.setText(quoteItems.getQuote());

        viewHolder.cardView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

             //how to pass data to "ParticularFragment" from here
            }
        });
    }

    @Override
    public int getItemCount() {
        return itemList.size();
    }
    class ViewHolder extends RecyclerView.ViewHolder {

        public TextView txtQuote;
        public CardView cardView;

        public ViewHolder(View itemView) {
            super(itemView);
            txtQuote = (TextView) itemView.findViewById(R.id.txtQuote);
            cardView = (CardView) itemView.findViewById(R.id.cardView);
        }
    }
}

在onclick中添加以下代码

ReciverFragment fragment = new ReciverFragment(); 
Bundle args = new Bundle();
args.putString("Your_Key", "Your_Value");
fragment.setArguments(args);
//Inflate the fragment
context.getFragmentManager().beginTransaction().add(R.id.container, fragment).commit();

注意：更改

private Context context;

到

private Activity context;

并且作为TopicsAdapter构造函数的参数从您的片段传递getActivity（）。

在onBindViewHolder上点击cardview时如何将数据传递给片段？
