当我在“回收器”视图中创建自定义卡片视图并单击“增量”按钮时，计数器将正常工作。但当我创建另一个cardview时，已经创建的卡计数器值重置为0。如何解决这个问题？
这是我的主要活动代码

        recyclerView2=(RecyclerView)findViewById(R.id.recycler_view2);

        recyclerView2.setHasFixedSize(true);

        layoutManager2=new LinearLayoutManager(this);

    }

        dialogBuilder.setView(dialogView);

这是我的Adapter类代码

    // Provide a reference to the views for each data item
    // Complex data items may need more than one view per item, and
    // you provide access to all the views for a data item in a view holder
    public class ViewHolder extends RecyclerView.ViewHolder {
        // each data item is just a string in this case
        public TextView tv;
        public View layout;
        public TextView counter_value;
        public ImageView increment,decrement, deleted;
        public int counter;

        public ViewHolder(View v) {
            super(v);
            layout = v;
            tv = (TextView) v.findViewById(R.id.textViewName);
            counter_value=(TextView) v.findViewById(R.id.counter);

    }

    }

        // set the view's size, margins, paddings and layout parameters
        ViewHolder vh = new ViewHolder(v);
        return vh;
    }

    // Replace the contents of a view (invoked by the layout manager)
    @Override
    public void onBindViewHolder(ViewHolder holder, final int position) {

        final String name = values.get(position);
        holder.tv.setText(name);
        final int[] counter={0};
        holder.deleted.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                remove(position);
            }
        });

        holder.decrement.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (counter[0] == 0) {
                    Toast.makeText(v.getContext(), "Can't add less than 0", Toast.LENGTH_SHORT).show();
                } else {
                    counter[0] -= 1;
                    holder.counter_value.setText(String.valueOf(counter[0]));
                }

            }
        });

        holder.increment.setOnClickListener(new View.OnClickListener() {
            @Override

    }

}
