android - 从自身更改 CardView 内的 TextView 中的文本

Question

想象一个带有按钮和文本字段的 CardView。当我按下按钮时，文本字段中的文本应该会发生变化。下面给出了我的 recyclerView 的代码，我在其中设置文本和按钮的监听器:

@Override
    public void onBindViewHolder(CategoriesDetailedViewHolder holder, int position) {

        final CategoryDetailedModel model = categoriesDetailedModels.get(position);
        holder.description.setText(model.getQuestion());

        holder.btnPlus.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                holder.description.setText("some text");
            }
        });
    }

主要问题在于字符串:

holder.description.setText("some text");

它不能从内部类访问。 有谁知道如何从自身更改卡片 View 中的文本。

public class CategoriesDetailedViewHolder extends RecyclerView.ViewHolder{
        CardView cv;
        TextView description;
        TextView positiveCounter;
        TextView negativeCounter;
        TextView btnPlus;
        View negativeCounterWrapper;
        View positiveCounterWrapper;
        CategoriesDetailedViewHolder(View itemView) {
            super(itemView);
            cv = (CardView)itemView.findViewById(R.id.cv);
            description = (TextView)itemView.findViewById(R.id.main_text);
            positiveCounter = (TextView)itemView.findViewById(R.id.tv_positive_count_in_circle);
            negativeCounter = (TextView)itemView.findViewById(R.id.tv_negative_count_in_circle);
            btnPlus = (TextView)itemView.findViewById(R.id.plus_button);

            positiveCounterWrapper = itemView.findViewById(R.id.positive_count_wrapper);
            negativeCounterWrapper = itemView.findViewById(R.id.negative_count_wrapper);
            cv.setPreventCornerOverlap(false);
        }
    }

    @Override
    public CategoriesDetailedViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.categories_detailed_list_row_view, parent, false);
        CategoriesDetailedViewHolder pvh = new CategoriesDetailedViewHolder(v);
        context = parent.getContext();
        return pvh;
    }

代替，

TextView description;

成功了，

public TextView description;

编辑: 更改以下内容，

@Override
    public void onBindViewHolder(CategoriesDetailedViewHolder holder, int position) { ... }

到，

@Override 
    public void onBindViewHolder( final CategoriesDetailedViewHolder holder, int position) { .... }
