如何将List <E>从RecyclerView适配器传递到RecyclerView Holder？-Java 学习之路

我一直试图找到上面问题的答案，但没有帖子似乎有帮助 . 我有一个RecyclerView适配器，我从数据库中获取List作为List：

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.RecyclerViewHolder> {

    public List<Note> noteList;
    private View.OnLongClickListener longClickListener;
    private Context context;

    public RecyclerViewAdapter(List<Note> noteList, View.OnLongClickListener longClickListener, Context context) {
        this.noteList = noteList;
        this.longClickListener = longClickListener;
        this.context = context;
    }

还有一个ViewHolder，我有一个onClickListener来查找使用 getLayoutPosition() 点击的视图的位置：

static class RecyclerViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        private TextView noteTitleText;
        private TextView noteDescriptionText;
        private TextView dateText;
        private TextView weekText;

        RecyclerViewHolder(View view) {
            super(view);

            noteTitleText = (TextView) view.findViewById(R.id.noteTitleText);
            noteDescriptionText = (TextView) view.findViewById(R.id.noteDescriptionText);
            dateText = (TextView) view.findViewById(R.id.dateText);
            weekText = (TextView) view.findViewById(R.id.weekText);

            view.setOnClickListener(this);
        }

        @Override
        public void onClick(View view) {
            int position = getLayoutPosition();

            // I want the noteList from the RecyclerViewAdapter here.
            Note note = noteList.get(position); 

            Log.d("Item Clicked", String.valueOf(position));

        }
    }

目的是我需要noteList以及onClick（）方法中RecyclerViewAdapter的所有注释，以使用intent填充Activity . 我该怎么办呢？

在尝试了一小时的解决方案之后，这就是我所确定的 . 我没有在ViewHolder中实现OnClickListener，而是在onBindViewHolder（）方法的RecyclerViewAdapter中实现了它，如下所示：

@Override
public void onBindViewHolder(final RecyclerViewHolder holder, final int position) {
        final Note note = noteList.get(position);

        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // The note and noteList can be accessed here.
            }
        });
    }
