我正在解析從JSON格式的url收到的響應字符串。代碼停在創建JSONArray的行。它不打印任何日誌或例外。當我嘗試調試時，我可以看到JSONArray被創建爲正確的值，但隨後代碼在稍後的行中突然停止。該代碼段是 -運行android代碼時未創建JSONArray
private String[] getWeatherDataFromJson(String forecastJsonStr, int numDays)
throws JSONException
{
JSONObject forecastJson = new JSONObject(forecastJsonStr);
Log.v("Jsonobject forcastJson", "done");
JSONArray weatherArray = forecastJson.getJSONArray(OWM_LIST);
Log.v("JsonArray", "done");
for (int i=0; i< weatherArray.length();i++){
JSONObject daydata = weatherArray.getJSONObject(i);
Log.v("daydata", "done");
JSONObject weatherobject = daydata.getJSONObject(OWM_WEATHER);
Log.v("weatherobject", "done");
String description = weatherobject.getString(OWM_DESCRIPTION);
JSONObject tempratureobject = daydata.getJSONObject(OWM_DESCRIPTION);
Log.v("tempratureobject", "done");
double high = tempratureobject.getDouble(OWM_MAX);
double low = tempratureobject.getDouble(OWM_MIN);
highAndLow = formatHighLows(high, low);
的JSON是 -

*代碼突然停在後面的線路全部*意味着有什麼不對。請再次檢查您的logcat以進行堆棧跟蹤。另外，它在哪裏停止？ – Rohit5k2
