The following response comes to the request

{ "status": "success", "message": "Успешный запрос", "code": 200, "data": { "2018-02-12": [ 36, 37, 38, 39, 40 ], "2018-02-13": [ 41, 42, 43, 44, 45 ] } }

That is, the response data comes with variable keys: today, tomorrow will be "2018-02-13" and "2018-02-14", and so every day.

Processing jsonschema2pojo data under the key "data" yields the following model:

 package NNN.NNNN.NNNNN.model; import java.util.List; import com.google.gson.annotations.Expose; import com.google.gson.annotations.SerializedName; public class Data { @SerializedName("2018-02-12") @Expose private List<Integer> _20180212 = null; @SerializedName("2018-02-13") @Expose private List<Integer> _20180213 = null; public List<Integer> get20180212() { return _20180212; } public void set20180212(List<Integer> _20180212) { this._20180212 = _20180212; } public List<Integer> get20180213() { return _20180213; } public void set20180213(List<Integer> _20180213) { this._20180213 = _20180213; } }

It is clear that such a model will become obsolete in a day and will produce empty values. Tell me, can such an answer be automatically parsed using the Retrofit library or only manually?

    Such data should be read in the Map. In this case, you need Map <String, ArrayList <Integer >>. Other data read in the fields of appropriate types. In general, a class should look like this:

     public class Response { private String status, message; private int code; private Map<String, ArrayList<Integer>> data; public Response(String status, String message, int code, Map<String, ArrayList<Integer>> data) { this.status=status; this.message=message; this.code=code; this.data=data; } public void setStatus(String status) { this.status = status; } public String getStatus() { return status; } public void setMessage(String message) { this.message = message; } public String getMessage() { return message; } public void setCode(int code) { this.code = code; } public int getCode() { return code; } public void setData(Map<String, ArrayList<Integer>> data) { this.data = data; } public Map<String, ArrayList<Integer>> getData() { return data; } }

    Typically, information on this topic can be found in the documentation, read carefully.

    • That is, you need to write: @SerializedName ("data") @Expose private Map <String, ArrayList <Integer >> data; and information will be automatically placed in the data field? I hope no need to manually poke around with JSONObject? And did you notice that data is not just a Map, but an ArrayList consisting of two elements of such a Map? - Pavel Sumarokov
    • Do not confuse Map and Pair, Map can contain any number of such pairs. - Andrei Chistobaev
    • Thank you. I did it all) - Pavel Sumarokov
    • Just met with the exact same problem, even JSON is similar. Is it by chance not wargaming? - Andrey Chistobaev
    • not. this project is called Cintru - Pavel Sumarokov

    enumerate object keys, write them into an array

     keys = Object.keys(obj)
