如何将 JSON 字符串转换为 JSON 数组列表？

Question

我有一个字符串，我想在列表中显示它，所以我必须在数组列表中转换它我该怎么做？我试过这些东西     String Result =response.body().getGetFlightAvailibilityResponse().getGetFlightAvailibilityResult().getGetFlightAvailibilityResponse().getFlightDetails();                    try {                        Gson gson = new Gson();                        Type type = new TypeToken<List<Object>>()                         {}.getType();                        List<String> contactList = gson.fromJson(Result,                         type);                      //  JSONArray jsonArray = new JSONArray(Result);                    } catch (Exception e) {                        e.printStackTrace();                    } 这是我的字符串[[SrNo,AirlineCode,FlightNo,FromAirportCode,ToAirportCode,DepDate,DepTime,ArrDate,ArrTime,FlightClass,FlightTime,TotalAmount,TaxAmount,Stops,ValCarrier,FromTerminal,ToTerminal,MainClass,FareBasis,AgencyCharge,FareType,AvailSeats,FlightTrack] ,[100YO,9W,346,BOM,DEL,04/10/2018,07:30,04/10/2018,09:40,O,130,3998,1798,0,9W,2,3,Y, ,0,N,0,,0$307|37|100YO],[101YO,9W,953,BOM,JAI,04/10/2018,14:35,04/10/2018,16:30,O,115 ,4550,1949,1,9W,2, 2,Y,,0,N,0,,0$307|37|101YO],[101YO,9W,788,JAI,DEL,04/10/2018,17： 00,04/10/2018,18:05,O,65,0,0,0,9W,2, 3,Y,,0,N,0,,0$307|37|101YO],[102YO,9W ,2418,BOM,JAI,04/10/2018,18:20,04/10/2018,20:10,O,110,4550,1949,1,9W,2,2,Y,,0,N, 0,,0$307|37|102YO],[102YO,9W,756,JAI,DEL,04/10/2018,21:15,04/10/2018,22:20,O,65,0,0, 0,9W,2, 3,Y,,0,N,0,,0$307|37|102YO],[103YO,9W,309,BOM,DEL,04/10/2018,19:00,04/10 /2018,21:15,V,135,4995,1845,0,9W,2, 3,Y,,0,N,0,,0$307|37|103YO],[104YO,9W,2374,BOM,LKO,04/10/2018,12:25,04 /10/2018,14:45,W,140,5053,2573,1,9W,2, 2,Y,,0,N,0,,0$307|37|104YO],[104YO,9W,856, LKO,DEL,04/10/2018,15:40,04/10/2018,17:00,W,80,0,0,0,9W,2,3,Y,,0,N,0,, 0$307|37|104YO],

Answer 1

在这里，您将获得 JSONObject，因此您可以将其转换为

JSONArray jsonArray = new JSONArray(readlocationFeed); 

line with following

JSONObject jsnobject = new JSONObject(readlocationFeed);

and after

JSONArray jsonArray = jsnobject.getJSONArray("locations");

for (int i = 0; i < jsonArray.length(); i++) {

    JSONObject explrObject = jsonArray.getJSONObject(i);

}

您可以在 Arraylist 上添加此对象。

Answer 2

This will help you.

JSONArray jsonArrayList = new JSONArray(); 

ArrayList<String> label=new ArrayList<>();

JSONArray jsonArray = new JSONArray(readlocationFeed); 

if(jsonArray.length()>0){

        for(int i=0;i<jsonArray.length();i++){

                JSONArray jsonArrayForValue = new JSONArray(jsonArray.get(i)); 

                if(i==0){

                ////////**********For Label/Header*******///////////

                        for(int j=0;j<jsonArrayForValue.length();j++){

                                label.add(jsonArrayForValue.get(j));

                        }

                }else{

                    JSONObject eachDeatail=new JSONObject();

                    for(int j=0;j<jsonArrayForValue.length();j++){

                        eachDeatail.put(label.get(j),jsonArrayForValue.get(label.get(j)).toString());

                        }   

                        jsonArrayList.add(eachDeatail);

                }

        }

}
