//删除购物车的代码holder1.btnDelete.setOnClickListener(new View.OnClickListener() {    @Override    public void onClick(View view) {        delPresenter.receive("3384", childList.get(i).get(i1).getPid()+"");        /**         * 当商家条目下商品删除完后,商家消失         * 及时刷新         */        List<JsonShopCarBean.DataBean.ListBean> beans = childList.get(i);        JsonShopCarBean.DataBean.ListBean remove = beans.remove(i1);        if (beans.size() == 0) {            childList.remove(i);            groupList.remove(i);        }        //算钱        EventBus.getDefault().post(computer());        //刷新适配器        notifyDataSetChanged();    }});
