Fetching json object from JSON string - android

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() {
return courseArrayList;
}
public void setCourseArrayList(ArrayList<Course> courseArrayList) {

https://github.com/google/gson
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 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");

How to get JSON field using GSON and #SerializedName ?

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;

Clear a Model class

I have a model class "JobPostBean" which I'm initiating in another model class and adding data using the second model class. I would like to clear any data which gets saved in the "JobPostBean" class. Is there any way to clear it either in "JobPostBean" class or in the second model class where its initialised? I would prefer to clear it using a single method rather than setting every item in the "JobPostBean" class to null.

At first Hold Data in ArrayList .If you want delete all data then You can Clear ArrayList
al_JobPostBean.clear();
The clear() method removes all the elements of ArrayList .

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!
