单击recyclerview项目的按钮，其他recyclerview项目的按钮也会响应

Question

我已经使用cardview创建了一个recyclerview，并在recyclerview的每个项目中添加了按钮。我已经集成了按钮点击事件。现在，当我点击其中一个recyclerview项目的按钮时，它会正常响应并且其他项目的按钮同时响应，就好像它们也被点击一样。问题是什么？怎么解决？

这是我的适配器代码。

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

    holder.title.setText(workers.get(position).getName());
    holder.rating.setRating(workers.get(position).getRatings());
    Picasso.with(context).load(workers.get(position).getImageLogo()).fit().into(holder.imageView);
    holder.plus.setTag("off");


    holder.plus.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            /// button click event
            if (holder.plus.getTag().toString().equals("off")) {
                holder.plus.setTag("on");
                holder.plus.setText("-");
                //show the options button using animation
                holder.layout.startAnimation(AnimationUtils.loadAnimation(v.getContext(), R.anim.left_to_right));
                holder.layout.setVisibility(View.VISIBLE);

            } else if (holder.plus.getTag().toString().equals("on")) {
                holder.plus.setTag("off");
                holder.plus.setText("+");
                //hide the options button using animation
                holder.layout.startAnimation(AnimationUtils.loadAnimation(v.getContext(), R.anim.right_to_left));
                final Handler handler = new Handler();
                handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        //disappear the button after 500ms
                        holder.layout.setVisibility(View.GONE);
                    }
                }, 500);
            }
        }
    });
}
