第一步：安裝GsonFormat外掛

首先，開啟Android studio設定介面，快捷鍵command+逗號(mac上的快捷鍵)，開啟Plugins點選Browse Respositories，然後搜尋GsonFormat，然後點選安裝，重啟Android Studio

2.建立JavaBean

按下快捷鍵command+n，然後選擇GsonFormat，把已經格式化好的json複製進來，點選OK就哦了！

3.給出一個相對複雜的json資料

{
    "title":{
        "name":"來米匯",
        "time":"2016-12-16"
 
,
        "info":{
            "code":"0",
            "message":"成功"
        }
    },
    "content":{
        "detail":[
            {
                "storename":"西二旗店",
                "itemlist":[
                    {
                        "id":"1",
                        "productname":"蘋果"
                    
 
},
                    {
                        "id":"2",
                        "productname":"香蕉"
                    },
                    {
                        "id":"3",
                        "productname":"橙子"
                    }
                ]
            },
            {
                "storename
 
":"霍營店",
                "itemlist":[
                    {
                        "id":"1",

                    },
                    {

                        "productname":"火龍果"
                    },
                    {
                        "id":"3",
                        "productname":"榴蓮"
                    }
                ]
            },
            {
                "storename":"回龍觀店",
                "itemlist":[
                    {
                        "id":"1",

                    },
                    {
                        "id":"2",
                        "productname":"黃瓜"
                    },
                    {
                        "id":"3",
                        "productname":"西紅柿"
                    }
                ]
            }
        ]
    }
