java - Android JSONObject 改组

Question

我有以下字符串到 json 代码:

json = new JSONObject(
                        "{\"Questions\":{"
                        + "\"1\":[\"ELSYS\",\"ELSYS2\",\"ELSYS3\",\"ELSYS4\"],"
                        + "\"2\":[\"1024\",\"2048\",\"512\",\"64\"],"
                        + "\"3\":[\"RANDOM1\",\"RANDOM2\",\"RANDOM3\",\"RANDOM4\"],"
                        + "\"4\":[\"A DOG1\",\"A DOG2\",\"A DOG3\",\"A DOG4\"],"
                        + "\"5\":[\"SOME WORD1\",\"SOME WORD2\",\"SOME WORD3\",\"SOME WORD4\"]}}");

初始化后，我将 JSON 打印到 LogCat:

Log.i(TAG, json.toString());

我的问题是 json 是网格化的。这是输出:

{"Questions":{"3":["RANDOM1","RANDOM2","RANDOM3","RANDOM4"],"2":["1024","2048","512","64"],"1":["ELSYS","ELSYS2","ELSYS3","ELSYS4"],"5":["SOME WORD1","SOME WORD2","SOME WORD3","SOME WORD4"],"4":["A DOG1","A DOG2","A DOG3","A DOG4"]}}

为了更具可读性，这里是来自 json 的解析信息:

key => 3 || value => RANDOM1,RANDOM2,RANDOM3,RANDOM4
key => 2 || value => 1024,2048,512,64
key => 1 || value => ELSYS,ELSYS2,ELSYS3,ELSYS4
key => 5 || value => SOME WORD1,SOME WORD2,SOME WORD3,SOME WORD4
key => 4 || value => A DOG1,A DOG2,A DOG3,A DOG4

如您所见，字符串的顺序不正确。我在普通的 Java 程序中尝试了相同的代码，它工作正常。当我在 android 中执行此操作时，问题就出现了。你知道可能是什么问题吗？ (我尝试清理项目)

更新

尝试使用“[”而不是“{”。抛出以下异常:

更新2你应该知道这些键“1”、“2”等也可以是字符串，所以我不使用它们对 json 进行排序，我只使用它们来查看顺序是否正确。将会有字符串代替这些“1”、“2”等。

Answer 1

来自 JSON 规范 http://www.json.org/

An object is an unordered set of name/value pairs

不用担心顺序，您对此无能为力。
