Android 实现RecyclerView嵌套RecyclerView 实现购物车的全选 反选 单选 商家全选

里层Adapter的实现
public class MyAdapter2  extends  RecyclerView.Adapter  {

    private Context context;
    private List data;
    private ongeshu ongeshu;
    private getsumprice getsumprice;


    public MyAdapter2(Context context, List data ) {
        this.context = context;
        this.data = data;

        //presenter = new ShopPresenter(MyAdapter2.this);
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = View.inflate(context, R.layout.rv_item2, null);
        ViewHolder holder=new ViewHolder(view);
        return holder;
    }

    @Override
    public void onBindViewHolder(final ViewHolder holder, final int position) {
        holder.mAmountView.setGoods_storage(50, data.get(position).num);
        holder.tv_name.setText(data.get(position).title);
        holder.tv_price.setText("￥" + data.get(position).bargainPrice);
        String images = data.get(position).images;
        String[] img = images.split("\\|");
        Glide.with(context).load(img[0]).into(holder.iv);
        //自定义控件的点击事件
        holder.mAmountView.setOnAmountChangeListener(new AmountView.OnAmountChangeListener() {
            @Override
            public void onAmountChange(View view, int amount) {
                data.get(position).num=amount;
                getsumprice.onsumprice();

            }
        });
        //给cb设置初始值
        boolean isselect = data.get(position).isselect;
        if(isselect)
        {
            holder.checkBox.setChecked(true);
            ongeshu.geshu();
            getsumprice.onsumprice();
        }
        else
        {
            holder.checkBox.setChecked(false);
        }

        holder.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
                if(b)
                {
                   data.get(position).isselect=true;
                }
                else
                {
                    data.get(position).isselect=false;
                }
                ongeshu.geshu();
                getsumprice.onsumprice();
            }
        });
    }
    @Override
    public int getItemCount() {
        return data.size();
    }

    public class ViewHolder extends RecyclerView.ViewHolder {

        private final TextView tv_name;
        private final TextView tv_price;
        private final CheckBox checkBox;
        private final ImageView iv;
        private final AmountView mAmountView;

        public ViewHolder(View itemView) {
            super(itemView);
            tv_name = itemView.findViewById(R.id.tv_name);

    public void setOngeshu(MyAdapter2.ongeshu ongeshu) {
        this.ongeshu = ongeshu;
    }

    public interface ongeshu{

        this.getsumprice = getsumprice;
    }

    public interface getsumprice{

}


外层adapter的实现

public class MyAdapter  extends RecyclerView.Adapter{
    private Context context;
    private List data;
    private onzong onzong;
    private getSumprice getSumprice;


    public MyAdapter(Context context, List data) {
        this.context = context;
        this.data = data;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        ViewHolder holder=new ViewHolder(view);
        return holder;
    }

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

        boolean  flag=true;
        for (Shop.DataBean.ListBean listBean : data.get(position).list) {
            if(listBean.isselect==false)
            {
                flag=false;
            }
        }
        holder.shopselect.setChecked(flag);
        holder.tv_title.setText(data.get(position).sellerName);
        LinearLayoutManager linearLayoutManager=new LinearLayoutManager(context);
        linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);


        holder.rv.setLayoutManager(linearLayoutManager);
        final MyAdapter2 adapter2=new MyAdapter2(context,data.get(position).list);
        holder.rv.setAdapter(adapter2);

        //点击商家商品全选
        holder.shopselect.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                for (Shop.DataBean.ListBean listBean : data.get(position).list) {
                     if(holder.shopselect.isChecked())
                     {

                }
                adapter2.notifyDataSetChanged();
                onzong.onshangjia();
                getSumprice.onSumprice();
            }
        });


        //调用小adapter的接口实现商品全选 商家选中
        adapter2.setOngeshu(new MyAdapter2.ongeshu() {
            @Override
            public void geshu() {
                boolean  flag=true;
                for (Shop.DataBean.ListBean listBean : data.get(position).list) {

                    {
                        flag=false;
                    }
                }
                holder.shopselect.setChecked(flag);
                onzong.onshangpin();
                getSumprice.onSumprice();
            }
        });
        adapter2.setGetsumprice(new MyAdapter2.getsumprice() {
            @Override
            public void onsumprice() {
                getSumprice.onSumprice();

            }
        });


    }
    @Override
    public int getItemCount() {
        return data.size();
    }
    public class ViewHolder extends RecyclerView.ViewHolder{

        private final TextView tv_title;
        private final RecyclerView rv;
