Question

我在从字符串创建JSONException时面临JSONArray。我已经使用JSON Validator验证了来自Webservice的响应字符串。

这是代码：

json = new JSONObject(); 
content = recieveData(json.toString(), m_sTimeTableUrl + sPGId);
if (content != null){
  Log.d(TAG, "got content:"+content);
  try {
    JSONArray jArray2 = new JSONArray(content);     //THE EXCEPTION FIRES HERE!
    Log.i(TAG, "Number of entries " + jArray2.length());
    Happening pHappening = null;
    ArrayList<Happening> pResult = new ArrayList<Happening>();
    for(int i = 0; i < jArray2.length(); i++){
      pHappening = new Happening();
      JSONObject jObject = jArray2.getJSONObject(i);
      pHappening.setEndtime(new Time(jObject.getInt("EndMinute")));
      pHappening.setDocent(jObject.getString("Lecturer"));
      pHappening.setRoom(jObject.getString("Room"));
      pHappening.setStartTime(new Time(jObject.getInt("StartMinute")));
      pHappening.setName(jObject.getString("Title"));
      pHappening.setDayOfWeek(jObject.getInt("Weekday"));
      pResult.add(pHappening);
    }
            //java.util.Arrays.sort(pResult);
   return pResult;
  }catch (JSONException e) {
    Log.e(TAG, e.toString());
  }

这就是我的内容字符串的样子：

        "Lecturer" : "Prof. Dr. Christian Schrödter",
        "OrgLecturId" : 10181,

Answer 1

JSONArray jArray2 = new JSONArray(content);

正在尝试使用JSONObject初始化JSONArray。你需要使用

JSONObject obj = new JSONObject(content);

因为content是JSON对象。

但是，键“Happenings”的值是 JSONArray，因此您可以使用它来初始化JSONArray。

创建JSONArray时出现Java JSONException
