android - 如何修复返回其他数字的 onClick cardView

Question

我有一个回收站，它显示了元素 list 、价格和状态。当我点击卡片时，我希望它显示我点击的商品的价格。但是无论何时，我都会点击。该卡返回其他卡的数据，但没有我点击的特定卡。

    public class ItemAdapter extends RecyclerView.Adapter<ItemAdapter.ItemHolder> {
private TextView viewName, viewPrice;
private CheckBox viewAvailability;

private Context context;
private List<Item> listItems;

@NonNull
@Override
public ItemAdapter.ItemHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {

    View view = LayoutInflater.from(context).inflate(R.layout.list_item, parent, false);
    return new ItemAdapter.ItemHolder(view);
}

@Override
public void onBindViewHolder(@NonNull ItemAdapter.ItemHolder holder, int position) {
    Item item = listItems.get(position);
    holder.setDetails(item);

}

@Override
public int getItemCount() {
    return listItems.size();
}


public class ItemHolder extends RecyclerView.ViewHolder {
    public ItemHolder(final View itemView) {
        super(itemView);
        viewName = itemView.findViewById(R.id.viewName);
        viewPrice = itemView.findViewById(R.id.viewPrice);
        viewAvailability = itemView.findViewById(R.id.viewAvailability);


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


            }
        });
    }

    public void setDetails(Item item) {
        viewName.setText(item.getName());
        viewPrice.setText(item.getPrice());
        int as = item.getAvailabilityStatus();

        if (as == 1) {
            viewAvailability.setChecked(true);
        } else {
        }
    }
}

public ItemAdapter(Context context, List<Item> objects) {
    this.context = context;
    this.listItems = objects;
}

试试这个代码，把 itemView onclick listner 放在 setDetails 里面

public void setDetails(Item item) {
        viewName.setText(item.getName());
        viewPrice.setText(item.getPrice());
        int as = item.getAvailabilityStatus();

        if (as == 1) {
            viewAvailability.setChecked(true);
        } else {
        }

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

                // here you will able to access valid item
            }
        });
    }
