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.

Below is my JSON data. I want to convert this to POJOs to store the Name,id,profession in a header table and the respective Jsonarray field in a child table.
JSON:
{
"Name": "Bob",
"id": 453345,
"Profession": "Clerk",
"Orders": [
{
"Item": "Milk",
"Qty": 3
},
{
"Item": "Bread",
"Qty": 3
}
]
}
Entity classes:
public class User {
private String name;
private Integer id;
private String Profession;
private JsonArray Orders;
private UserCart userCart;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getProfession() {
return Profession;
}
public void setProfession(String profession) {
Profession = profession;
}
public JsonArray getOrders() {
return Orders;
}
public void setOrders(JsonArray orders) {
Orders = orders;
}
public UserCart getUserCart() {
return userCart;
}
public void setUserCart(UserCart userCart) {
this.userCart = userCart;
}
}
public class UserCart {
private String item;
private Integer qty;
public String getItem() {
return item;
}
public void setItem(String item) {
this.item = item;
}
public Integer getQty() {
return qty;
}
public void setQty(Integer qty) {
this.qty = qty;
}
}
But when I do below; I get error
Cannot deserialize instance of org.json.JSONArray out of START_ARRAY
token
User user = new User();
JsonNode data = new ObjectMapper().readTree(jsonString);
user = headerMap.readValue(data.toString(), User.class);
How do I go about assigning the entire JSON to both the Java objects ?
Use List<UserCart> for array data in json and use #JsonProperty for mapping different json node name to java object field. No need to use extra field (JsonArray Orders) anymore.
#JsonProperty("Orders")
private List<UserCart> userCart;
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

}
}
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")
private String 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) {
this.vtiger_version = vtiger_version;
}
public String getMobile_module_version() {
return mobile_module_version;
}
public void setMobile_module_version(String mobile_module_version) {
this.mobile_module_version = mobile_module_version;
}
}
ModulesBean class in list
public class ModulesBean implements Serializable {
#SerializedName("id")

#SerializedName("isEntity")
private boolean isEntity;
#SerializedName("label")

I'am trying to parse data to a recyclerview, i had some problems about expecting JSONArray/JSONObject that i fixed with some help, but this moment I am a little bit lost in what to do in the Onresponse, the original - generatePhonesList(response.body()) isnt working.
this is my json and i am trying to parse the data inside the array results[] :
{
"success": true,
"metadata": {
"sort": "POPULARITY",
"total_products": 20,
"title": "Phones & Tablets",
"results": [

You are passing the APIReponse model to the generatePhonesList(List<Result> phonesList) function. You need to pass only the list of results in this function.
Replace this:
generatePhonesList(response.body());
with:
generatePhonesList(response.body().getMetadata().getResults());
Here getMetadata() and getResults() are the getter functions of metadata model and List.
If you pay close attention response.body() will provide you with class APIResponse. But you need is List<Result>. To achieve this, try response.body().getMetadata().getResults()
This should give you the desired output.

if (username.equals("admin") && pass.equals("Password!1")) {
Toast.makeText(getApplicationContext(), "Login Successfully", Toast.LENGTH_LONG)

Toast.makeText(getApplicationContext(), "Invalid Username and Password", Toast.LENGTH_LONG)

Some data is missing in your model structure for parsing data.
"result": {
"login": {
"userid": "1",
"session": "fa000f0a6c5a414e62dcc4cbf99175d6",
"vtiger_version": "5.2.0",
"mobile_module_version": "1.2.1"
},
there is a "login" jsonobject in your "result" object. But you missed the "login" element when you parse it. you should create a java class as LoginModel.
public class LoginModel {
#SerializedName("session")
#Expose
private String session;
#SerializedName("userid")
#Expose
private String userid;
#SerializedName("vtiger_version")
#Expose
private String vtiger_version;
and put login model in your GetModuleList class.
public class GetLoginModuleList {
#SerializedName("login")
#Expose
private LoginModel login;
I am trying to convert a complex object into related Java beans. However, some sub class can be not generated correctly.
I am just using simulate MS Adaptive card to create a set of Java beans classes. When I call Gson package or Alibaba fastJson package to parse my json data. it always shows the super class type.
This is just an experiment to test Gson & fastJson whether it can convert complex objects. which is running on the Android studio.
My demo json is like following:
{
"type": "AdaptiveCard",
"version": "1.0",
"id": "workloadQCactivity 20",
"speak": "activity 20 <break time=\"300ms\"/> at<break time=\"300ms\"/> <break time=\"300ms\"/>building<break time=\"300ms\"/>A<break time=\"300ms\"/>floor<break time=\"300ms\"/>1<break time=\"300ms\"/>room<break time=\"300ms\"/>1<break time=\"300ms\"/> ",
"body": [{
"type": "Container",
"items": [{
"type": "ColumnSet",
"columns": [{
"type": "Column",
"width": "Stretch",
"items": [{
"type": "TextBlock",
"size": "large",
"weight": "bolder",
"text": "activity 20 at building A floor 1 room 1",
"wrap": true
}]
}]
}]
}],
"actions": [{
"type": "Action.ShowCard",
"card": {
"type": "AdaptiveCard",
"version": "1.0",
"body": [{
"type": "TextBlock",
"size": "medium",
"weight": "bolder",
"isSubtle": true,
"text": "have thing to check list1",
"wrap": true
}, {
"type": "TextBlock",
"weight": "bolder",
"isSubtle": true,
"text": "this is section 1",
"wrap": true
}, {
"type": "TextBlock",
"isSubtle": true,
"text": "q1 of s1",
"wrap": true
}, {
"type": "TextBlock",
"isSubtle": true,
"text": "q2 of s2",
"wrap": true
}, {
"type": "TextBlock",
"weight": "bolder",
"isSubtle": true,
"text": "this is section 2",
"wrap": true
}, {
"type": "TextBlock",
"isSubtle": true,
"text": "q1 of s22",
"wrap": true
}, {
"type": "TextBlock",
"size": "medium",
"weight": "bolder",
"isSubtle": true,
"text": "have checklist 2",
"wrap": true
}, {
"type": "TextBlock",
"weight": "bolder",
"isSubtle": true,
"text": "section of the second checklist",
"wrap": true
}, {
"type": "TextBlock",
"isSubtle": true,
"text": "qqqqqq",
"wrap": true
}]
},
"title": "Show Checklist"
}]
}
Therefore, I just follow MS adaptive card to create following java beans.
First class: AdaptiveTypedElement
public class AdaptiveTypedElement {
#JsonProperty("additionalPorperties")
public Map<String, Object> additionalPorperties = new HashMap<String, Object>();
//#JsonProperty("type")
//public String type;
#JsonProperty("id")
public String id;
}
Second class: AdaptiveTypedElement
public class AdaptiveElement extends AdaptiveTypedElement {
#JsonProperty("spacing")
public AdaptiveSpacing spacing ;
#JsonProperty("separator")
public boolean separator = false;
#JsonProperty("speak")
public String speak;
#JsonProperty("separation")
// public AdaptiveSeparationStyle separation;
public String separation;
}
Third class AdaptiveContainer:
public class AdaptiveContainer extends AdaptiveElement {
#JsonProperty("typeName")
public String typeName = "Container";
#JsonProperty("type")
public String type = "Container";
#JsonProperty("items")
public List<AdaptiveElement> items = new ArrayList<AdaptiveElement>();
#JsonProperty("selectAction")
public AdaptiveAction selectAction = null;
#JsonProperty("style")
public AdaptiveContainerStyle style = AdaptiveContainerStyle.Default;
}
public class AdaptiveColumnSet extends AdaptiveElement {
#JsonProperty("typeName")
public final String typeName = "ColumnSet";
#JsonProperty("type")
public final String type = "ColumnSet";
#JsonProperty("columns")
public List<AdaptiveColumn> columns = new ArrayList<AdaptiveColumn>();
#JsonProperty("selectionAction")
public AdaptiveAction selectionAction = null;
}
public class AdaptiveColumn extends AdaptiveContainer{
#JsonProperty("typeName")
public final String typeName = "Column";
#JsonProperty("type")
public final String type = "Column";
#JsonProperty("size")
public String size;
#JsonProperty("with")
public String with;
}
public class AdaptiveAction {
#JsonProperty("title")
public String title;
#JsonProperty("speak")
public String speak;
}
public class AdaptiveShowCardAction extends AdaptiveAction {
#JsonProperty("typeName")
public final String typeName = "Action.ShowCard";
#JsonProperty("type")
public final String Type = "Action.ShowCard";
#JsonProperty("card")
public AdaptiveCard card;
}
public class AdaptiveTextBlock extends AdaptiveElement{
#JsonProperty("typeName")
public String typeName = "TextBlock";
#JsonProperty("type")
public String type = "TextBlock";
#JsonProperty("text")
public String text = "";
#JsonProperty("size")
public AdaptiveTextSize size;
#JsonProperty("weight")
public AdaptiveTextWeight weight;
#JsonProperty("color")
public AdaptiveTextColor color;
#JsonProperty("horizontalAlignment")
public AdaptiveHorizontalAlignment horizontalAlignment = AdaptiveHorizontalAlignment.Left;
#JsonProperty("wrap")
public boolean wrap = false;
#JsonProperty("isSubtle")
public boolean isSubtle = false;
#JsonProperty("maxLines")
public int maxLines = 0;
#JsonProperty("maxWidth")
public int maxWidth = 0;
}
public class AdaptiveCard extends AdaptiveTypedElement {
#JsonProperty("contentType")
public final String contentType = "application/vnd.microsoft.card.adaptive";
#JsonProperty("typeName")
public final String typeName = "AdaptiveCard";
#JsonProperty("type")
public String type = "AdaptiveCard";
#JsonProperty("body")
public List<AdaptiveElement> body = new ArrayList<AdaptiveElement>();
#JsonProperty("actions")
public List<AdaptiveAction> actions = new ArrayList<AdaptiveAction>();
#JsonProperty("speak")
public String speak = null;
#JsonProperty("title")
public String title;
#JsonProperty("version")
//public AdaptiveSchemaVersion version = null;
public String version = null;
#JsonProperty("fallbackText")
public String fallbackText = null;
#JsonProperty("lang")
public String lang = null;
}
In the end, I finally got AdaptiveCard Object. See my code:
return JSON.parseObject(attachJson, AdaptiveCard.class). Note that I add "implementation 'com.alibaba:fastjson:1.2.54'" in my Android Studio
When I check this object, I found the Body data member should be class "AdaptiveContainer " not "AdaptiveElement". I was wondering why it did not following subclass mechanism of OOP & OOD. I am expecting "AdaptiveContainer", but actually output is "AdaptiveElement".

rib-pet, your question has a far to big example. Anyway I tried to create a java class mapping for your sample using GSON
Action.java
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Action {
#SerializedName("type")
#Expose
private String type;
#SerializedName("card")
#Expose
private Card card;
#SerializedName("title")
#Expose
private String title;
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public Card getCard() {
return card;
}
public void setCard(Card card) {
this.card = card;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}
Body.java
package com.example;
import java.util.List;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Body {
#SerializedName("type")
#Expose
private String type;
#SerializedName("items")
#Expose
private List<Item> items = null;
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public List<Item> getItems() {
return items;
}
public void setItems(List<Item> items) {
this.items = items;
}
}
Body_.java (dependend on your wished model you should integrate this class better in some existing
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Body_ {
#SerializedName("type")
#Expose
private String type;
#SerializedName("size")
#Expose
private String size;
#SerializedName("weight")
#Expose
private String weight;
#SerializedName("isSubtle")
#Expose
private Boolean isSubtle;
#SerializedName("text")
#Expose
private String text;
#SerializedName("wrap")
#Expose
private Boolean wrap;
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getSize() {
return size;
}
public void setSize(String size) {
this.size = size;
}
public String getWeight() {
return weight;
}
public void setWeight(String weight) {
this.weight = weight;
}
public Boolean getIsSubtle() {
return isSubtle;
}
public void setIsSubtle(Boolean isSubtle) {
this.isSubtle = isSubtle;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public Boolean getWrap() {
return wrap;
}
public void setWrap(Boolean wrap) {
this.wrap = wrap;
}
}
Card.java
package com.example;
import java.util.List;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Card {
#SerializedName("type")
#Expose
private String type;
#SerializedName("version")
#Expose
private String version;
#SerializedName("body")
#Expose
private List<Body_> body = null;
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getVersion() {
return version;
}
public void setVersion(String version) {
this.version = version;
}
public List<Body_> getBody() {
return body;
}
public void setBody(List<Body_> body) {
this.body = body;
}
}
Column.java
package com.example;
import java.util.List;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Column {
#SerializedName("type")
#Expose
private String type;
#SerializedName("width")
#Expose
private String width;
#SerializedName("items")
#Expose
private List<Item_> items = null;
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getWidth() {
return width;
}
public void setWidth(String width) {
this.width = width;
}
public List<Item_> getItems() {
return items;
}
public void setItems(List<Item_> items) {
this.items = items;
}
}
Example.java
package com.example;
import java.util.List;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Example {
#SerializedName("type")
#Expose
private String type;
#SerializedName("version")
#Expose
private String version;
#SerializedName("id")
#Expose
private String id;
#SerializedName("speak")
#Expose
private String speak;
#SerializedName("body")
#Expose
private List<Body> body = null;
#SerializedName("actions")
#Expose
private List<Action> actions = null;
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getVersion() {
return version;
}
public void setVersion(String version) {
this.version = version;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getSpeak() {
return speak;
}
public void setSpeak(String speak) {
this.speak = speak;
}
public List<Body> getBody() {
return body;
}
public void setBody(List<Body> body) {
this.body = body;
}
public List<Action> getActions() {
return actions;
}
public void setActions(List<Action> actions) {
this.actions = actions;
}
}
Item.java
package com.example;
import java.util.List;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Item {
#SerializedName("type")
#Expose
private String type;
#SerializedName("columns")
#Expose
private List<Column> columns = null;
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public List<Column> getColumns() {
return columns;
}
public void setColumns(List<Column> columns) {
this.columns = columns;
}
}
Item_.java also here better integration needed
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Item_ {
#SerializedName("type")
#Expose
private String type;
#SerializedName("size")
#Expose
private String size;
#SerializedName("weight")
#Expose
private String weight;
#SerializedName("text")
#Expose
private String text;
#SerializedName("wrap")
#Expose
private Boolean wrap;
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getSize() {
return size;
}
public void setSize(String size) {
this.size = size;
}
public String getWeight() {
return weight;
}
public void setWeight(String weight) {
this.weight = weight;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public Boolean getWrap() {
return wrap;
}
public void setWrap(Boolean wrap) {
this.wrap = wrap;
}
}
hope it helps!
I've figured out this solution via the following solution:
JSONObject and JSONArray
JSONArray body = contentObj.getJSONArray("body");
JSONArray actions = contentObj.getJSONArray("actions");
title.setText(body.getJSONObject(0).getString("text"));
