Attempt to invoke virtual method 'xx.setData(java.util.List)' on a null object reference

Question

提示出问题的就是这两段代码，找了一天也不知道到底错在哪，求解答，感谢。

    private void setData() {
        tvShopName.setText(bean.getShopName());
        tvNotice.setText(bean.getShopNotice());
        Glide.with(this).load(bean.getShopPic())
                .error(R.mipmap.ic_launcher)
                .into(ivShopPic);
        adapter.setData(bean.getFoodList());
    }

   public void setData(List<FoodBean> beans){
        beans.clear();
        this.beans.addAll(beans);
        notifyDataSetChanged();//通知listview刷新数据
    }

Answer 1

应该是this.beans.clear();吧
要不然你传list有何意义那
还有先输出一下传入beans的list
看看是否为空null
