在 Android 中解析 JSON 时出错

Question

我正在从网站上抓取数据。我们得到的数据格式为

[

当我将上述数据转换为 Json 格式时，出现以下错误

    06-11 18:36:40.584: V/Error(657): Error in parsing Innerorg.json.JSONException: Value {"1":{"depTime":"5:09am+","arrStation":"Allawah Station ","arrTime":"5:11am+","train":"Eastern Suburbs and Illawarra train (CityRail) ","arrPlatform":"3","depStation":"Hurstville Station ","depPlatform":"3"}} at 4 of type org.json.JSONObject cannot be converted to JSONArray

如何在 Android 中解析这种类型的 json 字符串。有什么建议的朋友......？

Answer 1

那是因为你的 JSON 字符串构造不好。

试着把它放进去：http://jsonlint.com/它会告诉你当前的错误。

另外，请在http://json.org/ 阅读一些关于 JSON 的文档，因为您实际上犯了一些基本错误:)

如果您还提供您的 JSON 必须表示的内容，我可以显示您的 JSON 字符串的正确形式 :)

Answer 2

我的字符串如下所示

{
"result": "success",
"countryCodeList": [
{
"countryName": "World Wide",
"countryCode": "00"
},
{
"countryName": "Korea, Republic of",
"countryCode": "kr"
},
{
"countryName": "United States",
"countryCode": "us"
},-
{
"countryName": "Japan",
"countryCode": "jp"
},
{
"countryName": "China",
"countryCode": "cn"
},
{
"countryName": "India",
"countryCode": "in"
}
]
}

我已经完成了

JSONObject json = new JSONObject(jsonstring);
JSONArray nameArray = json.names();
JSONArray valArray = json.toJSONArray(nameArray);

JSONArray valArray1 = valArray.getJSONArray(1);

    valArray1.toString().replace("[", "");
            valArray1.toString().replace("]", "");

            int len = valArray1.length();

            for (int i = 0; i < valArray1.length(); i++) {

                Country country = new Country();
                JSONObject arr = valArray1.getJSONObject(i);

                country.setCountryCode(arr.getString("countryCode"));
                country.setCountryName(arr.getString("countryName"));
                arrCountries.add(country);
            }
