在Android中解析多个JSON对象

我对如何解析此JSON感到困惑。到目前为止，这是我的方法。还请告诉我在Android中解析JSON的正确方法

JSON:

{  
 "latitude":37.8267,
 "longitude":-122.423,
 "timezone":"America/Los_Angeles",
 "offset":-7,
 "currently":{  
  "time":1443322196,
  "summary":"Partly Cloudy",
  "icon":"partly-cloudy-night",
  "nearestStormDistance":13,
  "nearestStormBearing":77,
  "precipIntensity":0,
  "precipProbability":0,
  "temperature":63.94,
  "apparentTemperature":63.94,
  "dewPoint":55.46,
  "humidity":0.74,
  "windSpeed":8.59,
  "windBearing":277,
  "visibility":8.51,
  "cloudCover":0.44,
  "pressure":1010.39,
  "ozone":261.48
 },
  "minutely":{  
   "summary":"Partly cloudy for the hour.",
  "icon":"partly-cloudy-night",
  "data":[  
     {  
        "time":1443322140,
        "precipIntensity":0,
        "precipProbability":0
     },
 }

现在正在解析“当前”对象，但是当我尝试解析“分钟”对象时，它在Logcat中没有显示任何值

这是我的代码：

JSONObject forecast = new JSONObject(jsonData);
    JSONArray summary = new JSONArray(jsonData);

    String timezone = forecast.getString("timezone");
    String city = getLocationName(forecast.getDouble("latitude"), forecast.getDouble("longitude"));

    JSONObject currently = forecast.getJSONObject("currently");
    JSONArray hour = summary.getJSONArray("minutely");
    for (int i = 0; i < hour.length(); i++) {
        JSONObject jsonObject = hour.getJSONObject(i);
        String summary = jsonObject.getString("summary");
    }
    CurrentWeather currentWeather = new CurrentWeather();
    currentWeather.setHumidity(currently.getDouble("humidity"));
    currentWeather.setTime(currently.getLong("time"));
    currentWeather.setIcon(currently.getString("icon"));
    currentWeather.setPrecipChance(currently.getDouble("precipProbability"));
    currentWeather.setTemp(currently.getDouble("temperature"));
    currentWeather.setTimezone(timezone);
    currentWeather.setLocation(city);

根据您在注释中添加的端点URL的响应，解析看起来像这样

JSONObject forecast = new JSONObject(jsonData);

double latitude = forecast.getDouble("latitude");
double longitude= forecast.getDouble("longitude");
String timezone = forecast.getString("timezone");

JSONObject jsonObjCurrently= forecast.getJSONObject("currently");
//parse string, long and double objects within jsonObjCurrently accordingly

JSONObject jsonObjMinutely= forecast.getJSONObject("minutely");
String summary= jsonObjMinutely.getString("summary");
String icon= jsonObjMinutely.getString("icon");
JSONArray jsonArrayMinutelyData = jsonObjMinutely.getJSONArray("data");
for(int i=0; i<jsonArrayMinutelyData .length(); i++){
   JSONObject tempData = jsonArrayMinutelyData.get(i);
   long time = tempData.getLong("time");
   //parse the remaining object pairs.
}

JSONObject jsonObjHourly= forecast.getJSONObject("hourly");
//similar to minutely parsing. Only has more and different data 
JSONObject jsonObjDaily= forecast.getJSONObject("daily");
//similar to hourly parsing.
JSONObject jsonObjFlags= forecast.getJSONObject("flags");
//It has 5 array and 1 string object so parse accordingly.

我已经添加了解析逻辑，请相应地保存数据并使用它。
