如何使用android中的對象鍵排序json對象？

Question

由於JSON對象不可靠，當我從json文本文件創建新的json對象時，順序出錯。所以我決定重新訂購json對象。

正確的順序（JSON文件內容）

{ 
"211": { 
     "host": "https:\/\/s3-ap-southeast-1.amazonaws.com\/production-source\/ChangSha\/2013\/12\/09\/0\/0\/A\/Content\/", 
     "timestamp": 1386514507, 
     "cover": ["15\/Pg015.png", 
     "16\/Pg016.png", 
     "1\/Pg001.png", 
     "2\/Pg002.png"], 
     "year": "2013", 
     "month": "12", 
     "day": "09", 
     "issue": "2013-12-09", 
     "id": "211" 
    }, 
    "210": { 
     "host": "https:\/\/s3-ap-southeast-1.amazonaws.com\/production-source\/ChangSha\/2013\/12\/08\/0\/0\/A\/Content\/", 
     "timestamp": 1386415087, 
     "cover": ["1\/Pg001.png", 
     "2\/Pg002.png", 
     "3\/Pg003.png", 
     "4\/Pg004.png"], 
     "year": "2013", 
     "month": "12", 
     "day": "08", 
     "issue": "2013-12-08", 
     "id": "210" 
    }, 
    "209": { 
     "host": "https:\/\/s3-ap-southeast-1.amazonaws.com\/production-source\/ChangSha\/2013\/12\/07\/0\/0\/A\/Content\/", 
     "timestamp": 1386331278, 
     "cover": ["1\/Pg001.png", 
     "2\/Pg002.png", 
     "3\/Pg003.png", 
     "4\/Pg004.png"], 
     "year": "2013", 
     "month": "12", 
     "day": "07", 
     "issue": "2013-12-07", 
     "id": "209" 
    }, 
    "208": { 
     "host": "https:\/\/s3-ap-southeast-1.amazonaws.com\/production-source\/ChangSha\/2013\/12\/06\/0\/0\/A\/Content\/", 
     "timestamp": 1386255815, 
     "cover": ["15\/Pg015.png", 
     "16\/Pg016.png", 
     "1\/Pg001.png", 
     "2\/Pg002.png"], 
     "year": "2013", 
     "month": "12", 
     "day": "06", 
     "issue": "2013-12-06", 
     "id": "208" 
    } 
}

順序不正確（當我創建一個JSONObject）

我現在有不正確的命令jsonObject。如何用正確的順序創建一個新的json對象？謝謝

Answer 1

JSON對象沒有順序，它只是一張地圖。即使你在文件中按照想要的順序編寫JSON，一旦再次加載，它就不會有任何順序的概念。

如果你想命令，你必須使用一個數組：

[ 
    { 
    "id": "211", 
    ... 
    }, 
    { 
    "id": "210", 
    ... 
    }, 
    ... 
]
