Gson解析数组对象json文件

Question

各位友友们，我最近刚刚学习Android，碰到一个问题：Gson如何解析数组类型的Json（只用Gson解析）

[
{
"shopId":1,
"shopName":"蛋糕房",
"shopPicture":"http://10.113.104.89:8080/order/img/shop/shop1.png",
"foodList":[
    { 
    "foodId":"1",
    "foodName":"招牌丰收硕果12寸",
    },
    {
    "foodId":"2",
    "foodName":"玫瑰花创意蛋糕",
    }        
    ]
}
]

不知道这类Json用gson如何解析，指望各位友友指点，最好能有代码！谢谢大家了！

Answer 1

1:手动在外面包一层 {"list":[]},用于符合Gson解析
2:json数据格式不对 foodName 后面的逗号 ,要去掉
json：{"list":[
{
"shopId":1,
"shopName":"蛋糕房",
"shopPicture":"http://10.113.104.89:8080/order/img/shop/shop1.png",
"foodList":[
{
"foodId":"1",
"foodName":"招牌丰收硕果12寸"
},
{
"foodId":"2",
"foodName":"玫瑰花创意蛋糕"
}
]
}
]
}

结果如下：

  class ResultBean {
        public ArrayList<Item> list = new ArrayList<Item>();

        class Item {
            public int shopId;
            public String shopName;
            public String shopPicture;

            public ArrayList<FoodItem> foodList = new ArrayList<FoodItem>();

            class FoodItem {
                public String foodId;
                public String foodName;
            }
        }
    }

 String json="{\"list\":[\n" +
                "{\n" +
                "\"shopId\":1,\n" +
                "\"shopName\":\"蛋糕房\",\n" +
                "\"shopPicture\":\"http://10.113.104.89:8080/order/img/shop/shop1.png\",\n" +
                "\"foodList\":[\n" +
                "    { \n" +
                "    \"foodId\":\"1\",\n" +
                "    \"foodName\":\"招牌丰收硕果12寸\"\n" +
                "    },\n" +
                "    {\n" +
                "    \"foodId\":\"2\",\n" +
                "    \"foodName\":\"玫瑰花创意蛋糕\"\n" +
                "    }        \n" +
                "    ]\n" +
                "}\n" +
                "]\n" +
                "}";
        ResultBean result=   new Gson().fromJson(json,ResultBean.class);
