I have an issue with parsing the following JSON object
"paymentCurrency": "eur",
"paymentOptions": [
{
"paymentOptionId": "1CeGuJt2nkxmaMVf",
"paymentProfileUpdateNeeded": false,
"status": "DISABLED",
"supportedCardTypes": [
"CARD_TYPE_1",
"CARD_TYPE_2",
"CARD_TYPE_3"
],
"type": "TYPE_1"
},
{
"paymentOptionId": "J8iAFXRZZC07rJdG",
"status": "DISABLED",
"type": "TYPE_2"
}
],
"tripCost": "3000",
This is what I've tried until now. I cannot use anything besides #SerializedName and GSON to parse the arrays. Please find the model class below :
public class MatchDetails {
//other fields
#SerializedName("paymentOptions")
public ArrayList<PaymentOptionWrapper> options;
}
public class PaymentOptionWrapper {
public PaymentOption option;
}
public class PaymentOption {
#SerializedName("paymentOptionId")
public String paymentOptionId;
#SerializedName("paymentProfileUpdateNeeded")
public boolean profileUpdateNeeded;
#SerializedName("status")
public String status;
#SerializedName("supportedCardTypes")
public ArrayList<String> supportedCards;
#SerializedName("type")
public String type;
}
I have also tried not using a wrapper, mapping the list directly but it is still null.
Try this...
public class MatchDetails {
//other fields
#SerializedName("paymentOptions")
public ArrayList<PaymentOption> options;
public ArrayList<PaymentOption> getOptions() {
return options;
}
public void setOptions(ArrayList<PaymentOption> options) {
this.options = options;
}
}
class PaymentOption {
#SerializedName("paymentOptionId")
public String paymentOptionId;
#SerializedName("paymentProfileUpdateNeeded")
public boolean profileUpdateNeeded;
#SerializedName("status")
public String status;
#SerializedName("supportedCardTypes")
public ArrayList<String> supportedCards;
#SerializedName("type")
public String type;
public String getPaymentOptionId() {
return paymentOptionId;
}
public void setPaymentOptionId(String paymentOptionId) {
this.paymentOptionId = paymentOptionId;
}
public boolean isProfileUpdateNeeded() {
return profileUpdateNeeded;
}
public void setProfileUpdateNeeded(boolean profileUpdateNeeded) {
this.profileUpdateNeeded = profileUpdateNeeded;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public ArrayList<String> getSupportedCards() {
return supportedCards;
}
public void setSupportedCards(ArrayList<String> supportedCards) {
this.supportedCards = supportedCards;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
}
Try this:
public class MatchDetails implements Serializable
{
#SerializedName("paymentOptions")
#Expose
private List<PaymentOption> paymentOptions = null;
private final static long serialVersionUID = 7730239716376724487L;

My intention is to get the JSON Array item and display title,price,pic,detail_url from it. I found out how to display it one at a time so far, but couldn't find how to iterate the JSON object so that I can display the data in a listview. Please help, I am new to this and I've been stuck for quite awhile now. If you want to see my interface, retrofit instance etc just let me know.
private void taobaoSearch(){
TaobaoInterface retrofitInterface = RetrofitInstance.getRetrofitInstanceTaobao().create(TaobaoInterface.class);
Call<TaobaoModel> listCall = retrofitInterface.getTaobao("item_search", "40","default", "iphone","taobao-api.p.rapidapi.com", "//apikey hidden");
listCall.enqueue(new Callback<TaobaoModel>() {
#Override
public void onResponse(Call<TaobaoModel> call, Response<TaobaoModel> response) {
List<Result> retro=response.body().getitems();
generateDataList(retro);
}
#Override
public void onFailure(Call<TaobaoModel> call, Throwable t) {
System.out.println("FAILED");
System.out.println(call);
t.printStackTrace();
}
});
}
/*Method to generate List of data using RecyclerView with custom adapter*/
private void generateDataList(List<Result> dataList) {

I am trying to parse response from server in Android studio.
But I am not getting all values in Arraylist.
I have created ItemData.java and ItemResponse.java
I am Calling Api using getItemData Method:
public void getItemData() {
Call<ItemDataResponse> call = service.getData(token, "200");
call.enqueue(new Callback<ItemDataResponse>() {
#Override
public void onResponse(#NonNull Call<ItemDataResponse> call, #NonNull Response<ItemDataResponse> response) {
Log.d("dataFromServer", response.body.toString());
}
#Override
public void onFailure(#NonNull Call<ItemDataResponse> call, #NonNull Throwable t) {
progressDoalog.dismiss();
Toast.makeText(LiveVehiclesActivity.this, "Something went wrong...Please try later!", Toast.LENGTH_SHORT).show();
}
});
}
This is Json response:
{
"code":"1",
"items":[
{
"item_id":"200",
"speed":"2"
},
{
"item_id":"201",
"speed":"0"
}
]
}
ItemsResponse.java:
public class ItemDataResponse implements Serializable {
#SerializedName("code")
private String code;
#SerializedName("items")
#Expose
private List<ItemData> items;
public String getResponsecode() {
return responsecode;
}
public void setResponsecode(String responsecode) {
this.responsecode = responsecode;
}
public List<ItemData> getItems() {
return items;
}
public void setItems(List<ItemData> items) {
this.items = items;
}
}
ItemData.java
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class ItemData {
#SerializedName("item_id")
#Expose
private String itemId;
#SerializedName("speed")
#Expose
private String speed;
public String getItemId() {
return itemId;
}
public void setItemId(String itemId) {
this.itemId = itemId;
}
public String getSpeed() {
return speed;
}
public void setSpeed(String speed) {
this.speed = speed;
}
}
After run in debug mode I am getting response like:
code:"1"
items=null
your should modify
class ItemData {
private String item_id;
private String speed;
public String getItem_id() {
return item_id;
}
public void setItem_id(String item_id) {
this.item_id = item_id;
}
public String getSpeed() {
return speed;
}
public void setSpeed(String speed) {
this.speed = speed;
}
}
The ItemData model does not seem to be consistent with the JSON response.
i.e
{
"item_id":"200",
"speed":"2"
}
should map to:
class ItemData implements Serializable {
#SerializedName("item_id")
private String itemId;
#SerializedName("speed")
private String speed;
// getters and setters
}
Use SerializedName attribute for the field contains "_". Here for item_id in your ItemData class getting problem in mapping.
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class ItemData {
#SerializedName("item_id")
#Expose
private String itemId;
#SerializedName("speed")
#Expose
private String speed;
public String getItemId() {
return itemId;
}
public void setItemId(String itemId) {
this.itemId = itemId;
}
public String getSpeed() {
return speed;
}
public void setSpeed(String speed) {
this.speed = speed;
}
}
please change your ItemDataResponse class also
public class ItemDataResponse {
#SerializedName("code")
#Expose
private String code;
#SerializedName("items")
#Expose
private List<Item> items = null;
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public List<Item> getItems() {
return items;
}
public void setItems(List<Item> items) {
this.items = items;
}
}

Are you using the right model for mapping your response? Should it be:
DriverRequestModel driverRequestModel = response.body();
I am new to Android and I am developing app which has server side functionality. I am getting response in JSON format.
My response is shown as this image.
I know how to parse json using Volley but I don't know hot to parse using GSON. Previous code of my app was written by some one else. Now I have to complete this code. but I do not know how he getting data from JSON string.
I need JSON arrays in different activity. Array response:
image
Here is some snaps of my code.
Code for adapter for activity one
topicListAdapter = new TopicListAdapter(TopicActivity.this,
myCourseListMain. getCourseArrayList().get(Integer.parseInt(course_position)).
getTopicListMain().getTopicDetailsArrayList(), flag);
listAlltopics.setAdapter(topicListAdapter);
in which I got list of topics
here is code for second activity list adapter
lessionListAdapter = new LessionListAdapter(LessionActivity.this,
myCourseListMain. getCourseArrayList(). get(Integer.parseInt(course_position)).
getTopicListMain().getTopicDetailsArrayList().get(Integer.parseInt(topic_position)).getLessionArrayList(), flag);
by this code i got array of lession in second activity
Now I want sublession array in third activity but I don't know how to get it.
Here is what I tried
lessionListAdapter = new DummyAdapter(DummyTopicList.this,
myCourseListMain . getCourseArrayList(). get(Integer.parseInt(course_position)).
getTopicListMain() . getTopicDetailsArrayList() .get(Integer.parseInt(topic_position)).
getLessionLIstMain() .getLessionLIstDetailArrayList().get(Integer.parseInt(lession_position)). , flag);
listAlllessions.setAdapter(lessionListAdapter);
Here are some other classes which helpful to you for understand
public class MyCourseListMain {
#SerializedName("data")
private ArrayList<Course> courseArrayList;
public ArrayList<Course> getCourseArrayList() {

public void setCourseArrayList(ArrayList<Course> courseArrayList) {

Make your object have same construct with your data which you got.And
YourObject val = new Gson().fromJson(new String(YourString.getBytes("ISO-8859-1"),
"UTF-8"), YourObject.class);
finally i got my solution by below code.
lessionListAdapter = new DummyAdapter(DummyTopicList.this,
myCourseListMain . getCourseArrayList(). get(Integer.parseInt(course_position)).
getTopicListMain() . getTopicDetailsArrayList() .get(Integer.parseInt(topic_position)).
getLessionArrayList().get(Integer.parseInt((lession_position))).getLessionLIstDetailArrayList() , flag);
listAlllessions.setAdapter(lessionListAdapter);
i also made some few classes to handle json array.
public class SubLessionDetail {
#SerializedName("lesson_id")
private String lession_id;
#SerializedName("title")
private String title;
#SerializedName("locked")
private String locked;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getLocked() {
return locked;
}
public void setLocked(String locked) {
this.locked = locked;
}
public String getLession_id() {
return lession_id;
}
public void setLession_id(String lession_id) {
this.lession_id = lession_id;
}
}
My model getter setter class looks like this:-
#JsonIgnoreProperties(ignoreUnknown = true)
public class CuratedOffers {
public CuratedOffers() {
}
#JsonProperty("response")
private String response;
public String getResponse() {
return response;
}
public void setResponse(String response) {
this.response = response;
}
#JsonProperty("data")
private Data mData;
public Data getmData() {
return mData;
}
public void setmData(Data mData) {
this.mData = mData;
}
#JsonIgnoreProperties(ignoreUnknown = true)
public class Data{
#JsonProperty("vendors")
private List<Vendor> vendorList;
public List<Vendor> getVendorList() {
return vendorList;
}
public void setVendorList(List<Vendor> vendorList) {
this.vendorList = vendorList;
}
}
#JsonIgnoreProperties(ignoreUnknown = true)
public static class Vendor {
#JsonProperty("id")
private String Id;
public String getId() {
return Id;
}
public void setId(String id) {
Id = id;
}
#JsonProperty("name")
private String venName;
public String getVenName() {
return venName;
}
public void setVenName(String venName) {
this.venName = venName;
}
#JsonProperty("image")
private String image;
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
#JsonProperty("logo")
private String logo;
public String getLogo() {
return logo;
}
public void setLogo(String logo) {
this.logo = logo;
}
#JsonProperty("offers")
private String offers;
public String getOffers() {
return offers;
}
public void setOffers(String offers) {
this.offers = offers;
}
#JsonProperty("description")
private String offer_description;
public void setOffer_description(String offer_description) {
this.offer_description = offer_description;
}
public String getOffer_description() {
return offer_description;
}
}
}
And i using Jackson while compiling through gradle ie:-
compile 'com.fasterxml.jackson.core:jackson-databind:2.4.2'
compile 'com.fasterxml.jackson.core:jackson-annotations:2.4.2'
compile 'com.fasterxml.jackson.core:jackson-core:2.4.2'
After compiling i keep getting this error in my stacktrace
com.fasterxml.jackson.databind.JsonMappingException: No suitable constructor found for type [simple type, class com.yoy.CuratedOffers$Data]: can not instantiate from JSON object (need to add/enable type information?)
Searched SO without any suitable answers.Help would be appreciated!!
As suggested by #vilpel89 i had forgot to declare a static nested class inside CuratedOffers class.Now my updated class is:-
#JsonIgnoreProperties(ignoreUnknown = true)
public class CuratedOffers {
public CuratedOffers() {
}
#JsonProperty("response")
private String response;
public String getResponse() {
return response;
}
public void setResponse(String response) {
this.response = response;
}
#JsonProperty("data")
private Data mData;
public Data getmData() {
return mData;
}
public void setmData(Data mData) {
this.mData = mData;
}
#JsonIgnoreProperties(ignoreUnknown = true)
public static class Data{
public Data() {
}
#JsonProperty("vendors")
private List<Vendor> vendorList;
public List<Vendor> getVendorList() {
return vendorList;
}
public void setVendorList(List<Vendor> vendorList) {
this.vendorList = vendorList;
}
}
#JsonIgnoreProperties(ignoreUnknown = true)
public static class Vendor {
public Vendor() {
}
#JsonProperty("id")
private String Id;
public String getId() {
return Id;
}
public void setId(String id) {
Id = id;
}
#JsonProperty("name")
private String venName;
public String getVenName() {
return venName;
}
public void setVenName(String venName) {
this.venName = venName;
}
#JsonProperty("image")
private String image;
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
#JsonProperty("logo")
private String logo;
public String getLogo() {
return logo;
}
public void setLogo(String logo) {
this.logo = logo;
}
#JsonProperty("offers")
private String offers;
public String getOffers() {
return offers;
}
public void setOffers(String offers) {
this.offers = offers;
}
#JsonProperty("description")
private String offer_description;
public void setOffer_description(String offer_description) {
this.offer_description = offer_description;
}
public String getOffer_description() {
return offer_description;
}
}
}
Added a static constructor to my Data class as well as Vendor Class and also added default constructors to it.Now it's working like a charm!Hope it might help someone someday!
