我有一个像这样的JSON。它是一个很长的字符串。我只是粘贴了一些部分，整个部分由http://jsonlint.org/检查。在JSON中没有错误。
{
"1": {
"fajr": "00:0-33",
"sunrise": "12:10",
"zuhr": "17:45",
"asr": "20:48",
"maghrib": "23:19",
"isha": "24:52"
},
"2": {
"fajr": "00:0-32",
"sunrise": "12:09",
"zuhr": "17:45",
"asr": "20:49",
"maghrib": "23:21",
"isha": "24:53"
},
"3": {
"fajr": "00:0-30",
"sunrise": "12:07",
"zuhr": "17:45",
"asr": "20:50",
"maghrib": "23:22",
"isha": "24:54"
}
}
我像
一样解析它 HttpRequest request = HttpRequest.get(URL);
jsonData = request.body();
System.out.println(jsonData);
JSONArray jsonArray = new JSONArray(jsonData);
for (int i = 0; i <= jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
// GET PRAYER DETAILS
PrayerTime pt = new PrayerTime();
pt.setFajr(jsonObject.getString(FAJR));
pt.setSunrise(jsonObject.getString(SUNRISE));
pt.setJohr(jsonObject.getString(ZUHR));
pt.setAsar(jsonObject.getString(ASR));
pt.setMagrib(jsonObject.getString(MAGRIB));
pt.setEisha(jsonObject.getString(ISHA));
Log.e("PrayerTime", "" + pt.getSunrise());
}`
我有一个像

我错过了什么？
答案 0 :(得分：2)
在JSON字符串中，有两个符号可指导您完成解析：
{ - 表示JSONObject
[ - 表示JSONArray
虽然您的Json有效，但由于没有＆＃34; []＆＃34;，因此无法检测到JSONArray。
要解析此json，请将代码更改为：
JSONObject jsonObject = new JSONObject(jsonData) ;
JSONObject json_one = jsonObject.getJSONObject("1");
JSONObject json_two = jsonObject.getJSONObject("2");
JSONObject json_three = jsonObject.getJSONObject("3");
然后：
PrayerTime pt = new PrayerTime();
pt.setFajr(json_one.getString(FAJR));
pt.setSunrise(json_one.getString(SUNRISE));
...
答案 1 :(得分：1)
问题是这个字符串不包含任何JSONArray并且你试图解析json数组
如果没有JSONArray而不是JSONArray jsonArray = new JSONArray(jsonData);这条线是没用的
您可以像这样解决您的问题
Log.i("jsonData", jsonData);
try{
JSONObject jobj1=new JSONObject(jsonData);
for(int i=0;i<31;i++){
if(jobj1.has(""+i)){
JSONObject jobj2=jobj1.getJSONObject(""+i);
fazarData.add(jobj2.getString("fajr"));
}
}
Log.i("fajr", ""+fazarData);
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
