Modules list is not coming after parsing json

Hi in the below code modules list is not coming after parsing the json and i have created different pojo classes for different classes and i am not getting the expected json response from server.
Can any one tell me where i did the mistake for json parsing and complete json is not coming as json
Activity.java:
final String username = username1.getText().toString();
final String password = password1.getText().toString();
String operation = "loginAndFetchModules";
final GetNoticeDataService service = RetrofitInstance.getRetrofitInstance().create(GetNoticeDataService.class);
/** Call the method with parameter in the interface to get the notice data*/
Call<LoginAndFetchModules> call1 = service.GetLoginModuleList(operation, username, password);
/**Log the URL called*/
Log.wtf("URL Called", call1.request().url() + "");
call1.enqueue(new Callback<LoginAndFetchModules>() {
#Override
public void onResponse(Call<LoginAndFetchModules> call1, Response<LoginAndFetchModules> response) {
Log.e("response",new Gson().toJson(response.body()));
if (response.isSuccessful()) {
Log.e("response",new Gson().toJson(response.body()));
LoginAndFetchModules loginAndFetchModules = response.body();
String success = loginAndFetchModules.getSuccess();
if (success.equals("true")) {
ArrayList<String> modules = new ArrayList<String>();
try {
JSONArray jsonArray = new JSONArray(loginAndFetchModules);
for (int i = 0; i < jsonArray.length(); i++) {
modules.add(jsonArray.get(i).toString());

},
{
"id": "3",
"name": "Accounts",
"isEntity": true,
"label": "Accounts",

}]
}
}

According json response, it return Results instead of List. Change your LoginAndFetchModules like below:
public class LoginAndFetchModules {
#SerializedName("success")
private String success;
#SerializedName("result")
private Results result;
public Results getResult() {
return result;
}
public void setResult(Results result) {
this.result = result;
}
public String getSuccess() {
return success;
}
public void setSuccess(String success) {
this.success = success;
}
}
And then parse the informations like below:
if (response.isSuccessful()) {
LoginAndFetchModules loginAndFetchModules = response.body();
String success = loginAndFetchModules.getSuccess();
if (success.equals("true")) {
Results results = loginAndFetchModules.getResult();
//parse login details
GetLoginListDetails loginDetails = results.getLogin();
String userId = loginDetails.getUserid();
//parse modules
ArrayList<LoginListForModules> modules = results.getModules();
//parse module information
for(LoginListForModules module: modules) {
String id = module.getId();
String name = module.getName();
...
}
}
}

you can create classes for response like this
first class is ResultReponse
public class ResultReponse implements Serializable {
#SerializedName("success")
private boolean success;
#SerializedName("result")
private ResultBean result;
public boolean isSuccess() {
return success;
}
public void setSuccess(boolean success) {
this.success = success;
}
public ResultBean getResult() {
return result;
}
public void setResult(ResultBean result) {
this.result = result;
}
}
ResultBean class
public class ResultBean implements Serializable{
#SerializedName("login")
private LoginBean login;
#SerializedName("modules")
private List<ModulesBean> modules;
public LoginBean getLogin() {
return login;
}
public void setLogin(LoginBean login) {
this.login = login;
}
public List<ModulesBean> getModules() {
return modules;
}
public void setModules(List<ModulesBean> modules) {
this.modules = modules;
}
}
loginBean class inside ResultBean
public class LoginBean implements Serializable {
#SerializedName("userid")
private String userid;
#SerializedName("session")
private String session;
#SerializedName("vtiger_version")
private String vtiger_version;
#SerializedName("mobile_module_version")

public String getUserid() {
return userid;
}
public void setUserid(String userid) {
this.userid = userid;
}
public String getSession() {
return session;
}
public void setSession(String session) {
this.session = session;
}
public String getVtiger_version() {
return vtiger_version;
}
public void setVtiger_version(String vtiger_version) {

public String getMobile_module_version() {
return mobile_module_version;
}
public void setMobile_module_version(String mobile_module_version) {

this is how i call it

getPhoto.enqueue(new Callback<List<UserDataResponse>>() {
#Override
public void onResponse(Call<List<UserDataResponse>> call, Response<List<UserDataResponse>>response) {
// String iserror = response.body().getIserror();
// Jika login berhasil maka data nama yang ada di response API
// akan diparsing ke activity selanjutnya.
List<UserDataResponse> userDatalist = response.body();
//Creating an String array for the ListView
String[] iserror = new String[userDatalist.size()];
//looping through all the heroes and inserting the names inside the string array
for (int i = 0; i < userDatalist.size(); i++) {
iserror[i] = userDatalist.get(i).getIserror();
if (iserror.equals("false")) {
String[] url = new String[userDatalist.size()];
url[i] = userDatalist.get(i).getImages().getimage_Url();
showPhoto(url);
}
}
#Override
public void onFailure(Call<List<UserDataResponse>> call, Throwable t){
Log.e("debug", "onFailure: ERROR > " + t.toString());
}
});
}
and my question is how i can call response "url" from array i tried to call method getimage_Url() after method getImage() but i cannot call it
url[i] = userDatalist.get(i).getImages().getimage_Url();

According your above json, it's return Object rather than Array. So, modify your F0_getPhoto to handle this.
public void F0_getPhoto(){
Call<UserDataResponse> getPhoto = mApiService.getImage(
String.valueOf(mPrefs.getUserID()));
getPhoto.enqueue(new Callback<UserDataResponse>() {
#Override
public void onResponse(Call<UserDataResponse> call, Response<UserDataResponse>response) {
// String iserror = response.body().getIserror();
// Jika login berhasil maka data nama yang ada di response API
// akan diparsing ke activity selanjutnya.
UserDataResponse userData = response.body();
//Creating an String array for the ListView
String error = userData.getIserror();
List<Image> images = userData.getImages();
String[] url = new String[images.size()];
//looping through all the heroes and inserting the names inside the string array
if (iserror.equals("false")) {
for (int i = 0; i < images.size(); i++) {
url[i] = images.getimage_Url();
}
showPhoto(url);
}
#Override
public void onFailure(Call<UserDataResponse> call, Throwable t){
Log.e("debug", "onFailure: ERROR > " + t.toString());
}
});
}
}

How to parse all json objects and send them inside a class?

This is the response JSON from Volley:
{
"status":true,
"data":{
"product_id":"12",
"product_ogpm_id":"OGPR1000485",
"product_part_number":"6ED1 057-1AA01-0BA0",
"escape_part_number":"6ed10571aa010ba0",
"product_name":"USB PC Cable",
"product_uom":"",
"product_image":"",
"product_description":"",
"product_manufacturer":"Siemens",
"manufacturer_id":"4",
"replace_id":"0",
"replace_date":"0000-00-00 00:00:00",
"product_added_date":"2017-09-12 00:57:15",
"product_added_by":"Jayank Chopra",
"product_modified_date":"0000-00-00 00:00:00",
"product_modified_by":"",
"product_status":"1",
"manufacturer_name":"Siemens",
"contracted_id":"1",
"data_sheets":[
]
},
"message":"Product found!"
}
For Parsing I use Gson Like this:
/* BarcodeSearchResponse responseObj = new Gson().fromJson(responseJson.toString(), BarcodeSearchResponse.class);
where BarcodeSearchResponse class is this:
public class BarcodeSearchResponse{
public ArrayList<ScanData> data;
}
*/
And ScanData is a class that contains :

And your ScanData Class should use this Data Class as following.
public class ScanData {
#SerializedName("status")
#Expose
private Boolean status;
#SerializedName("data")
#Expose
private Data data;
#SerializedName("message")
#Expose
private String message;
public Boolean getStatus() {

public void setStatus(Boolean status) {
this.status = status;
}
public Data getData() {
return data;
}
public void setData(Data data) {
this.data = data;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
P.S.
I have not made it parcelable, I guess you can do that by yourself.

Map multi-level json string into class object in java

I have following JSON structure:
{
"result": {
"category": [{
"id": "3",
"name": "category name",
"slug": "sllug",
"image": "imageurl",
"sub-categories": [{
"id": "3",
"name": "category name",
"slug": "sllug",
"image": "imageurl",
"sub-categories": [{
"id": "3",
"name": "category name",
"slug": "sllug",
"image": "imageurl",
"sub-categories": []
}]
}]
},
{
"id": "3",
"name": "category name",
"slug": "sllug",
"image": "imageurl",
"sub-categories": []
}
]
}
}
I need to create class with the above JSON.
I have created two classes as HomeCategoryModel and HomeSubCategoryModel.
There may be multiple sub-categories in each level.
How to map this type of json into classes.
HomeCategoryModel class:
public class HomeCategoryModel {
public int Id;
public String Name;
public String Slug;
public String ImageUrl;
public ArrayList<HomeSubCategoryModel> SubCategories;
//...
//getter, setter
}
HomeSubCategory class:
public class HomeSubCategoryModel {
public int Id;
public String Name;
public String Slug;
public String ImageUrl;
public ArrayList<HomeSubCategoryModel> SubCategories;
//getter setter
}
I have tried to parse using recursive function like this but doesn't seem to work:
JSONObject allLists = jsonObject.getJSONObject("result");
JSONArray catArray = allLists.getJSONArray("category");
ArrayList<HomeCategoryModel> categoryList = new ArrayList<HomeCategoryModel>();
for (int i = 0; i < catArray.length(); i++) {
JSONObject jObj = catArray.getJSONObject(i);
HomeCategoryModel categoryModel = new HomeCategoryModel();
categoryModel.setId(Integer.parseInt(jObj.getString("id")));
categoryModel.setName(jObj.getString("name"));
categoryModel.setSlug(jObj.getString("slug"));
categoryModel.setImageUrl(jObj.getString("image"));
JSONArray productsArray = jObj.getJSONArray("sub-categories");
if (productsArray.length() > 0) {
parseSubCategories(productsArray);
}
categoryList.add(categoryModel);
}
And:
public static ArrayList<HomeSubCategoryModel> parseSubCategories(JSONArray arr) {
ArrayList<HomeSubCategoryModel> subLists = new ArrayList<HomeSubCategoryModel>();
for (int i = 0; i < arr.length(); i++) {
try {
JSONObject childObj = arr.getJSONObject(i);
HomeSubCategoryModel categoryModel = new HomeSubCategoryModel();
categoryModel.setId(Integer.parseInt(childObj.getString("id")));
categoryModel.setName(childObj.getString("name"));
categoryModel.setSlug(childObj.getString("slug"));
categoryModel.setImageUrl(childObj.getString("image"));
JSONArray subArray = childObj.getJSONArray("sub-categories");
if (subArray.length() > 0) {
parseSubCategories(subArray);
}
subLists.add(categoryModel);
} catch (JSONException e) {
e.printStackTrace();
}
}
return subLists;
}
Please suggest me. Thank you.

if you would like to use Gson then i can suggest something like below.
Generate your POJO like this
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Example {
#SerializedName("result")
#Expose
private Result result;
public Result getResult() {
return result;
}
public void setResult(Result result) {
this.result = result;
}
public class Result {
#SerializedName("category")
#Expose
private List < Category > category = null;
public List < Category > getCategory() {
return category;
}
public void setCategory(List < Category > category) {
this.category = category;
}
}
public class Category {
#SerializedName("id")
#Expose
private String id;
#SerializedName("name")
#Expose
private String name;
#SerializedName("slug")
#Expose
private String slug;
#SerializedName("image")
#Expose
private String image;
#SerializedName("sub-categories")
#Expose
private List < SubCategory > subCategories = null;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSlug() {
return slug;
}
public void setSlug(String slug) {
this.slug = slug;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
public List < SubCategory > getSubCategories() {
return subCategories;
}
public void setSubCategories(List < SubCategory > subCategories) {
this.subCategories = subCategories;
}
}
public class SubCategory_ {
#SerializedName("id")
#Expose
private String id;
#SerializedName("name")
#Expose
private String name;
#SerializedName("slug")
#Expose
private String slug;
#SerializedName("image")
#Expose
private String image;
#SerializedName("sub-categories")
#Expose
private List < Object > subCategories = null;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSlug() {
return slug;
}
public void setSlug(String slug) {
this.slug = slug;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
public List < Object > getSubCategories() {
return subCategories;
}
public void setSubCategories(List < Object > subCategories) {
this.subCategories = subCategories;
}
}
}
and then
Gson gson = new Gson();
Example exp = gson.fromJson("your json string",Example.class);
And you are done.

How to deserialize a JSON Object in a multidimensional array

I have this JSON data and I would like to deserialize it with Android to get it as an object to use in my class.
I get this folowing error :
Could not read JSON: Unrecognized field "card_details"
[
{
"id": "9",
"cat_id": "CAT-8584ce02f180b57a8c6d66570f696e02",

Here is my AsyncTask to retrieve the data:
private class HttpRequestTaskCarte extends AsyncTask<Void,Void,Item[]> {
#Override

try {
final String url = "http://domain.com/link.php?target=multi";
RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
Item[] greeting = restTemplate.getForObject(url, Item[].class);
return greeting;
} catch (Exception e) {
//Toast.makeText(getActivity(), "Error Loading !", Toast.LENGTH_SHORT).show();
Log.e("MainActivity", e.getMessage(), e);
}
return null;
}
protected void onPreExecute(){
progressDialog = new ProgressDialog(getActivity(),
R.style.AppTheme_Dark_Dialog);
progressDialog.setIndeterminate(true);
progressDialog.setMessage("chargement des elements...");
progressDialog.show();
}
#Override
protected void onPostExecute(Item[] greeting) {
Log.d("okokok",""+greeting.length);
progressDialog.dismiss();
}

JSONArray array=new JSONArray(your data);
JSONObject obj=array.getJSONObject(0);
JSONObject cardDetail=obj.getJSONObject("card_details");

Hii u can use the following code:
JSONArray jsonarray = new JSONArray(jsonStr);
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject jsonobject = jsonarray.getJSONObject(i);
String name = jsonobject.getString("name");
String url = jsonobject.getString("url");
}
