java - org.json.JSONException:字符19处的未终止对象

Question

我一直在android中的示例Firebase项目中工作，我正在手动将值添加到Firebase DB中。我将以下数据添加到数据库中并在解析json时遇到以下异常

org.json.JSONException：的字符19处的未终止对象

{GK=[{option1=1.5 hour, Question1=HI, answer=OptionC, option3=1hour, option4=None, option2=2hour}, {option1=15, Question1=jkl, answer=OptionD, option3=25, option4=70, option2=45}, {option1=Oil lamp, Question1=jkl, answer=OptionD, option3=Newspaper, option4=None, option2=kindling wood}], Sports=[{option1=FNLAKDS, Question1=gk1, option3=ram, option4=ram, option2=ram}, {option1=FNLAKDS, Question1=gk2, option3=ram, option4=ram, option2=ram}, {option1=FNLAKDS, Question1=gk3, option3=ram, option4=ram, option2=ram}]} 1

由于我在字符串中添加了逗号，因此我对引发此错误感到困惑。任何帮助将不胜感激。

我的Android代码

  String Jsondatas=dataSnapshot.getValue().toString();
      try {
                        JSONObject jsonobj=new JSONObject(Jsondatas);
                            JSONArray gkArray = jsonobj.getJSONArray("GK");
                            for(int i=0;i<gkArray.length();i++){
                                JSONObject obj_gk = gkArray.getJSONObject(i);

您尝试解析的json无效。字符串文字应该用双引号引起来，赋值（=）用:完成。

我已将这些修复程序应用于您的json：

{
   "G":[
      {
         "option1":"1.5 hour",
         "Question1":"HI",
         "answer":"OptionC",
         "option3":"1hour",
         "option4":"None",
         "option2":"2hour"
      },
      {
         "option1":15,
         "Question1":"jkl",
         "answer":"OptionD",
         "option3":25,
         "option4":70,
         "option2":45
      },
      {
         "option1":"Oil lamp",
         "Question1":"jkl",
         "answer":"OptionD",
         "option3":"Newspaper",
         "option4":"None",
         "option2":"kindling wood"
      }
   ],
   "Sports":[
      {
         "option1":"FNLAKDS",
         "Question1":"gk1",
         "option3":"ram",
         "option4":"ram",
         "option2":"ram"
      },
      {
         "option1":"FNLAKDS",
         "Question1":"gk2",
         "option3":"ram",
         "option4":"ram",
         "option2":"ram"
      },
      {
         "option1":"FNLAKDS",
         "Question1":"gk3",
         "option3":"ram",
         "option4":"ram",
         "option2":"ram"
      }
   ]
}

我建议您使用诸如 https://jsonformatter.curiousconcept.com/之类的json验证器来帮助您编写有效的json。
