我必须将下面嵌套的JSON数组的数据解析到我的应用程序中。我很困惑如何从中获取值。因为它太复杂了网址是“http://gaadiready.com/flight_api/getFlightSearchResults/?key=PPSYrvnMnS&trip_type=domestic&flight_mode=ONE&from=Bangalore/BLR&to=Calicut/CCJ&depart_date=05-06-2015&return_date=06-06-2015&no_adult=1&no_child=0&no_infant=0&cabin_type=E”
JSON响应由嵌套数组和对象组成。我使用Volley库函数来解析JSON。我想从响应中获取值以生成列表视图。但我没有得到输出。任何人帮我解决这个问题。我不熟悉嵌套的JSON数组。

我到目前为止尝试过的代码如下所示，我正在使用凌空进行解析
private void json_parser(JSONArray jarray){
try {
flightList=new ArrayList<Flight>();
for (int i = 0; i < jarray.length(); i++) {
JSONObject object = jarray.getJSONObject(i);
JSONArray departure_details=object.getJSONArray("departure_details");
if(departure_details!=null)
{
for(int j=0;j<departure_details.length();j++)
{
JSONObject object2=departure_details.getJSONObject(j);
String flight_count=object2.getString("flight_count");
JSONArray flight_details=object2.getJSONArray("flight_details");
if(flight_details!=null)
{
for(int k=0;k<flight_details.length();k++)
{
JSONObject object3=flight_details.getJSONObject(k);
String flight_name=object3.getString("airline_name");
String dep_location_code=object3.getString("departure_location_code");
String arr_location_code=object3.getString("arrival_location_code");
String dep_time=object3.getString("departure_time");
String arr_time=object3.getString("arrival_time");
JSONObject fare_details=object.getJSONObject("fare_details");
Toast.makeText(getApplicationContext(),object.getString("depart_from_location_code"), Toast.LENGTH_LONG).show();
flightList.add(new Flight( object.getString("depart_from_location_code"),object.getString("depart_to_location_code"),flight_count,flight_name,object.getString("depart_date"),object.getString("depart_date"),dep_time,arr_time,dep_location_code,arr_location_code,dep_location_code,arr_location_code));
}}}}}
list.setAdapter( new FlightListAdapter(ctx, R.layout.flight_list, flightList) );
