空时如何将图像设置为购物车活动

Question

如何在购物车活动中不设置购物车项目图像。我使用翻新来填充购物车活动中的recyclerview，该翻新将json结果传递给arraylist。当arraylist为空时，我想设置空的购物车图像。我该怎么办？

我的购物车活动代码如下：

ModelCart modelRecycler = new ModelCart();
                JSONObject dataobj = dataArray.getJSONObject(i);

                modelRecycler.setImgURL(dataobj.getString("imgURL"));
                modelRecycler.setName(dataobj.getString("name"));
 modelRecyclerArrayList.add(modelRecycler);
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext(),RecyclerView.VERTICAL,false);
            recV_cartItems.setLayoutManager(mLayoutManager);
            recV_cartItems.setItemAnimator(new DefaultItemAnimator());

            //cart items adapter
            mAdapter = new CartItemsAdapter(this,modelRecyclerArrayList);
            recV_cartItems.setAdapter(mAdapter);
