Parsing of multiple Arrays in android

Parsing of multiple Arrays in android - java

Please tell me how i can parse this model, i am a fresher in android. i tried like this way:-
{ "error": false, "response": { "comdata": [{ "id": "35", "address": "Address" }], "empdata": [{ "cid": "33", "comid": "35", "empname": "test", "empdob": "0000-00-00" }, { "cid": "33", "comid": "35", "empname": "test", "empdob": "0000-00-00" }] }
Gson gson = new Gson();
String json = gson.toJson(result);
JSONObject jObj = new JSONObject(json);
if (jObj.getString("error").equalsIgnoreCase("false")) {
JSONObject object = jObj.getJSONObject("response");
for (int i = 0; i < object.length(); i++) {
JSONArray jsonArray = object.getJSONArray("parentdata");
JSONObject jsonObject = jsonArray.getJSONObject(0);
//Something write here
JSONArray jsonArray1 = object.getJSONArray("childata");
for (int a = 0; a < jsonArray1.length(); a++) {
JSONObject object1 = jsonArray1.getJSONObject(a);
} return "true";
}return "true";
}else{
}

Your JSON is invalid correct JSON will look like this.
{
"error": false,
"response": {
"comdata": [
{
"id": "35",
"address": "Address"
}
],
"empdata": [
{
"cid": "33",
"comid": "35",
"empname": "test",
"empdob": "0000-00-00"
},
{
"cid": "33",
"comid": "35",
"empname": "test",
"empdob": "0000-00-00"
}
]
}
}
You can parse the JSON using below code.
private void parseResponse(String result) {
try {
JSONObject jsonObject = new JSONObject(result);
if (jsonObject.getBoolean("error")) {
JSONObject response = jsonObject.getJSONObject("response");
JSONArray jsonArray1 = response.getJSONArray("comdata");
List<ComData> comdataList = new ArrayList<>();
for (int i = 0; i < jsonArray1.length(); i++) {
ComData comData = new ComData();
comData.setId(jsonArray1.getJSONObject(i).getString("id"));
comData.setAddress(jsonArray1.getJSONObject(i).getString("address"));
comdataList.add(comData);
}
JSONArray jsonArray2 = response.getJSONArray("empdata");
List<EmpData> empdataList = new ArrayList<>();
for (int i = 0; i < jsonArray2.length(); i++) {
EmpData empData = new EmpData();
empData.setCid(jsonArray2.getJSONObject(i).getString("cid"));
empData.setComid(jsonArray2.getJSONObject(i).getString("comid"));
empData.setEmpname(jsonArray2.getJSONObject(i).getString("empname"));
empData.setEmpdob(jsonArray2.getJSONObject(i).getString("empdob"));
empdataList.add(empData);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
Or you can easily parse JSON to POJO using GSON, refer César Ferreira's answer.

Your JSON is invalid you should have it something like this:
{
"error": false,
"response": {
"comdata": [{
"id": "10",
"username": null,
"email": "example#gmail.com"
}],
"empdata": [{
"eid": "33",
"empname": "test",
"empdob": "0000-00-00",
"empgender": "test",
"empphoto": ""
}],
"someData": [{
"eid": "34",
"empname": "test",
"empdob": "0000-00-00",
"empgender": "test",
"empphoto": ""
}]
}
}
The property someData I had to add it so it would be a valid JSON, I don't know if it fits your requirements.
You can use jsonschematopojo to generate a class like this:
Comdatum class
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Comdatum {
#SerializedName("id")
#Expose
private String id;
#SerializedName("username")
#Expose
private Object username;
#SerializedName("email")
#Expose
private String email;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public Object getUsername() {
return username;
}
public void setUsername(Object username) {
this.username = username;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
Data class
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Data {
#SerializedName("error")
#Expose
private Boolean error;
#SerializedName("response")
#Expose
private Response response;
public Boolean getError() {
return error;
}
public void setError(Boolean error) {
this.error = error;
}
public Response getResponse() {
return response;
}
public void setResponse(Response response) {
this.response = response;
}
}
Empdatum Class
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
import package com.example;
public class Empdatum {
#SerializedName("eid")
#Expose
private String eid;
#SerializedName("empname")
#Expose
private String empname;
#SerializedName("empdob")
#Expose
private String empdob;
#SerializedName("empgender")
#Expose
private String empgender;
#SerializedName("empphoto")
#Expose
private String empphoto;
public String getEid() {
return eid;
}
public void setEid(String eid) {
this.eid = eid;
}
public String getEmpname() {
return empname;
}
public void setEmpname(String empname) {
this.empname = empname;
}
public String getEmpdob() {
return empdob;
}
public void setEmpdob(String empdob) {
this.empdob = empdob;
}
public String getEmpgender() {
return empgender;
}
public void setEmpgender(String empgender) {
this.empgender = empgender;
}
public String getEmpphoto() {
return empphoto;
}
public void setEmpphoto(String empphoto) {
this.empphoto = empphoto;
}
}
Response Class
package com.example;
import java.util.List;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Response {
#SerializedName("comdata")
#Expose
private List<Comdatum> comdata = null;
#SerializedName("empdata")
#Expose
private List<Empdatum> empdata = null;
#SerializedName("someData")
#Expose
private List<SomeDatum> someData = null;
public List<Comdatum> getComdata() {
return comdata;
}
public void setComdata(List<Comdatum> comdata) {
this.comdata = comdata;
}
public List<Empdatum> getEmpdata() {
return empdata;
}
public void setEmpdata(List<Empdatum> empdata) {
this.empdata = empdata;
}
public List<SomeDatum> getSomeData() {
return someData;
}
public void setSomeData(List<SomeDatum> someData) {
this.someData = someData;
}
}
SomeDatum Class
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class SomeDatum {
#SerializedName("eid")
#Expose
private String eid;
#SerializedName("empname")
#Expose
private String empname;
#SerializedName("empdob")
#Expose
private String empdob;
#SerializedName("empgender")
#Expose
private String empgender;
#SerializedName("empphoto")
#Expose
private String empphoto;
public String getEid() {
return eid;
}
public void setEid(String eid) {
this.eid = eid;
}
public String getEmpname() {
return empname;
}
public void setEmpname(String empname) {
this.empname = empname;
}
public String getEmpdob() {
return empdob;
}
public void setEmpdob(String empdob) {
this.empdob = empdob;
}
public String getEmpgender() {
return empgender;
}
public void setEmpgender(String empgender) {
this.empgender = empgender;
}
public String getEmpphoto() {
return empphoto;
}
public void setEmpphoto(String empphoto) {
this.empphoto = empphoto;
}
}
And Then you can just do something like this:
String jsonString = "Your JSON String";
Gson converter = new Gson();
Data settingsdata = converter.fromJson(jsonString , Data.class);

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;

Gson - Parse from Json to a typed ArrayList<T>

Can someone please help me? Thanks

Thanks GhostCat. I removed the _embedded from the response and the object itself and it started working. It was third party webservices was sending the response with _. It's working now.

How to convert Json into a Java bean object?

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;

}
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;

public class Body {
#SerializedName("type")
#Expose
private String type;
#SerializedName("items")

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

}
Card.java
package com.example;
import java.util.List;

public void setText(String text) {

public Boolean getWrap() {

public void setWrap(Boolean 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"));

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",
"app_id": "null",
"status": "1",
"lft": "1",
"rgt": "2",
"parent_cat_id": "0",
"added_date": "2017-01-12 12:41:29",
"last_edit_date": "2017-01-12 12:46:09",
"language_id": "0",

"validity": "1"
}
}
]
Here is my AsyncTask to retrieve the data:
private class HttpRequestTaskCarte extends AsyncTask<Void,Void,Item[]> {
#Override
protected Item[] doInBackground(Void... params) {
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();
}
}
And here is the class that I am using to deserialize:
public class Item {
private List<card_details> carte;

public void setId(String id) {
this.id = id;

}
public void setParent_cat_id(String parent_cat_id) {
this.parent_cat_id = parent_cat_id;
}
public String getAdded_date() {

}
public void setAdded_date(String added_date) {
this.added_date = added_date;
}
public String getLast_edit_date() {

}

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");
}
