将此字符串提供给 JSONObject 构造函数的输入参数。

String str="";//Give your json string here
JSONObject object= new JSONObject(str);

注意：要插入"使用转义序列，所以添加"by \"。

如果你的字符串从这个“{”开始然后把你的整个字符串放进去

  JSONObjectjb=new JSONObject(YourString);//it convert into json object

如果您的字符串从这个“[”开始，那么将您的整个字符串放入：-

  JSONArray jr=new JSONArray(YourString); //it convert into jsonArray

只需将您的字符串作为输入参数传递给 JSONObject 构造函数。

String test="your json string";
JSONObject object= new JSONObject(test);

您还可以使用Gson：

String test = "your json string";
Gson gson = new Gson();
gson.toJson(test);

它是一个免费和开源的 JSON 解析库，可以与 Android 完美配合，是的，真的就是这么简单！！

试试这个工具来验证你的 json 字符串：http: //jsonlint.com/

我认为您提供的 JSON 字符串无效。

要将有效的 JSON 字符串转换为 JSON 对象，您可以尝试类似的方法；

JSONObject object = new JSONObject("your valid json string here");

你的 json 无效你可以在这里查看jsonviewer.stack.hu

JsonArray 中的第 10 个元素有问题：

"10": {
        "Id": "290",
        "name": "BiwkI\u00c3\u0084",
        "0": {
            "Id": "298",
            "name": "hnhml hm\u00c3\u0080jnIw"
        },
        "1": {
            "Id": "299",
            "name": "P\u00c3\u00b2Zn\w"
        },
        "2": {
            "Id": "300",
            "name": "skent{_j\u00c2\u00b3"
        },
        "3": {
            "Id": "301",
            "name": "a\u00c3\u00a4p\u00c3\u0085h"
        },
        "4": {
            "Id": "304",
            "name": "BZyIp\u00c3\u0080_m/"
          }

    },

"name": "BZyIp\u00c3\u0080_m/"从这一行中，如果您最后删除，"/"那么您将 String 转换为 JSONObject

JSONObject object= new JSONObject(str);

或者这是您的完整有效 json String ：
