Parsing and storing a json response in android

Parsing and storing a json response in android - java

My JSON response has the following structure.
How should i parse it to store in a list in java with the structure maintained.
Does GSON provide a solution or should i use multidimensional array list?
I need to pass each of the tag array to a different view pager what approach should I follow.
{
"tag": [
{
"listing_count": 5,
"listings": [
{
"source": "source1",
"data": {
"image": "image1",
"name": "name1"
},
"name": "name1"
}
]
},
{
"listing_count": 5,
"listings": [
{
"source": "source2",
"data": {
"image": "imag2",
"name": "name2"
},
"name": "name2"
}
]
}
]
}
EDIT:
I have created the classes as suggested in the answer..I am having trouble creating the GSON response class.
This is what I have created:
public GsonRequest(int method, String url, Class<T> clazz,
Listener<T> listener, ErrorListener errorListener, Gson gson) {
super(Method.GET, url, errorListener);
this.mClazz = clazz;
this.mListener = listener;
mGson = gson;
}

The gson class should be something like this:
public class TagList {
ArrayList<Tag> tags;
public static class Tag {
int listing_count;
ArrayList<Listings> listings;
public int getListing_count() {
return listing_count;
}
public void setListing_count(int listing_count) {
this.listing_count = listing_count;
}
public ArrayList<Listings> getListings() {
return listings;
}
public void setListings(ArrayList<Listings> listings) {
this.listings = listings;
}
}
public static class Listings {
String source;
Data data;
String name;
public String getSource() {
return source;
}
public void setSource(String source) {
this.source = source;
}
public Data getData() {
return data;
}
public void setData(Data data) {
this.data = data;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
public static class Data {
String image;
String name;
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}

Getting Json object and Json Array in Same KEY

I am getting JSON Object when their is only one response(Plan) and JSON Array when their is more than one response(plan).How to handle JSON Response?
JSON ARRAY when their is more than one plan.
{
"ocrNumber": "0123456",
"userName": "dddd",
"plan": [{
"lat": "13.1234",
"long": "7.1234",
"imagepath": "sd / image / demo.jpg"
},{
"lat": "13.1234",
"long": "7.1234",
"imagepath": "sd / image / demo.jpg"
}]
}
JSON OBJECT when their is only one plan.
{
"ocrNumber": "0123456",
"userName": "dddd",
"plan": {
"lat": "13.1234",
"long": "7.1234",
"imagepath": "sd / image / demo.jpg"
}
}

add dependencies in your app level gradle file.
implementation 'com.google.code.gson:gson:2.8.5'
Create MyResponse.java
public class MyResponse {
#SerializedName("ocrNumber")
private String ocrNumber;
#SerializedName("userName")
private String userName;
#SerializedName("plan")
private ArrayList<Plan> plan;
public String getOcrNumber() {
return ocrNumber;
}
public void setOcrNumber(String ocrNumber) {
this.ocrNumber = ocrNumber;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public ArrayList<Plan> getPlan() {
return plan;
}
public void setPlan(ArrayList<Plan> plan) {
this.plan = plan;
}
}
create Plan.java class
public class Plan {
#SerializedName("lat")
private String lat;
#SerializedName("long")
private String longStr;
#SerializedName("imagepath")
private String imagepath;
public String getLat() {
return lat;
}
public void setLat(String lat) {
this.lat = lat;
}
public String getLongStr() {
return longStr;
}
public void setLongStr(String longStr) {
this.longStr = longStr;
}
public String getImagepath() {
return imagepath;
}
public void setImagepath(String imagepath) {
this.imagepath = imagepath;
}
}
Convert your jsonString to object using Gson
Gson gson = new Gson();
MyResponse response = gson.fromJson(yourJsonString, MyResponse.class);

Parse Json array with multiple objects using retrofit 2 in android

I'm using retrofit 2 for networking functions in my project, and I'm able to parse the json object responses from the server but now I'm supposed to parse a json array that look like this

Is my pojo is right ?
My problem is, I can't parse this response. Any help will be appreciated.
Thanks in advance
EDIT :
This is my request to server (using rest api)
#GET("url")
Call<AssetResponse> getAssetList();
EDIT 2: I've changed the code to List, as suggested by Niko Adrianus Yuwono.
This is the new changes
private void getAssets() {
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addInterceptor(logging);
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(Constants.BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.client(httpClient.build())
.build();
final ApiInterface apiInterface = retrofit.create(ApiInterface.class);
final AssetRequest assetRequest = new AssetRequest();
assetRequest.setAcc_tok(ACCESS_TOKEN);
final Call<List<AssetResponse>> assetList = apiInterface.getAssetList();
assetList.enqueue(new Callback <List<AssetResponse>>() {
#Override
public void onResponse(Call<List<AssetResponse>> call, Response<List<AssetResponse>> response) {
int statusCode = response.code();
List<AssetResponse> assetResponseList = response.body();
if (statusCode == 200) {
for (int i = 0; i < assetResponseList.size(); i++ ){
Integer id_asset = assetResponseList.get(i).getId_asset();
Integer id_category = assetResponseList.get(i).getId_category();
Integer status = assetResponseList.get(i).getStatus();
String name = assetResponseList.get(i).getName();
Log.d("Assets ","Asset id_asset bb : " + id_asset);
Log.d("Assets ","Asset id_category bb : " + id_category);
Log.d("Assets ","Asset name bb : " + name);
Log.d("Assets ","Asset status bb : " + status);
Double val = assetResponseList.get(i).getAssetRate().getValue();
Log.d("val ","val is : " +val);
}
} else {
Toast.makeText(getContext(), "network error " + statusCode, Toast.LENGTH_LONG).show();
}
}
#Override
public void onFailure(Call<List<AssetResponse>> call, Throwable t) {
Log.d("Asset GET Failure", "onFailure: " + t.getMessage());
//showProgress(false);
}
});
}
and this is the response from the server

Whenever I access the inner objects it throws error like the above

Your POJO looks right, but your JSON response is a JSONArray so you need to declare it as a List of Objects rather than an Object
#GET("url")
Call<List<AssetResponse>> getAssetList();
And you need to change your inner class access to public so GSON can see the setter and getter of that class.

Your Json key value data is changing from one index to another.
Wrong Json:
[{
//Make this either integer or boolean
"rank": 1,
// best rate is object here in the next index, it's treated as boolean.
"best_rate": {
"id_asset": "1",
"value": "5000",
"loan_to_value": "50",
"offered": "2500",
"annual_rate": "3",
"quantity": "5",
"rank": "1"
}
},
{
"rank":false,
"best_rate":false,
}
]
I have a complete project shared on github with your json.
https://github.com/lingarajsankaravelu/retrofit2v.git
Retrofit code should be like this as i mentioned in the question comment.
#GET("url")
Call<List<AssetResponse>> getAssetList();
As you have requested to explain the changes in your pojo class it should be like this.

Seperate your inner class like above. Seperating your inner class model will be useful if you are working on a large project. where you don't have to write the same pojo class again. you can use this seperate class structure instead.

You can use this site to generate POJO class. Just enter your JSON response and choose which JSON type you using like GSON,Jackson.etc. and You get perfect POJO classes. no need to change anything.
http://www.jsonschema2pojo.org/

Your Retrofit interface should be
#GET("url")
Call<List<AssetReponse>> getAssessList();
And make sure that your variable name same with key on JSON Response Or you can use annotation #SerializedName for that & for make it simple you can use JSON to POJO Online converter : http://www.jsonschema2pojo.org/

Rest Assured - Post nested POJO in Body

I'm trying to write an API class to send requests and handle responses from an API. Parts of the API have requests that require JSON bodies attached to the request such as this sample:
{
"Title": "string",
"Status": "string",
"ActFinish": "Date",
"ActHrs": "float",
"ActStart": "Date",
"ActualResults": "string",
"AssigneeUserId": "int",
"CustomFields": [
{
"Id": "string",
"Name": "string",
"Value": "string"
}
],
"Description": "string",
"EstFinish": "Date",
"EstHrs": "float",
"EstHrsRemaining": "float",
"EstStart": "Date",
"ExpectedResults": "string",
"FolderId": "int",
"FunctionalAreaCode": "string",
"HowFoundCode": "string",
"IssueCode": "string",
"ModuleCode": "string",
"PctComplete": "int",
"PriorityCode": "string",
"Resolution": "string",
"ResolutionCode": "string",
"SeverityCode": "string",
"SoftwareVersionCode": "string",
"StepsToRepro": "string"
}
The best way to do this I found through reading the Rest Assured documentation is with POJOs mentioned here: https://github.com/rest-assured/rest-assured/wiki/Usage#serialization
My POJO looks like this:
public class RequestDefectPost {

public String[] customFields;

public String description;
public Timestamp estFinish;
public float estHours;
public float estHrsRemaining;
public Timestamp estStart;
public String expectedResults;
public int folderId;
public String functionalAreaCode;
public String howFoundCode;
public String issueCode;
public String moduleCode;
public int pctComplete;
public String priorityCode;
public String resolutionCode;
public String severityCode;
public String softwareVersionCode;
public String stepsToRepro;
public RequestDefectPost(String title, String status) {
this.title = title;

With my current POJO, the JSON being spit out by Rest Assured looks like this:
{
"title": "Test",
"status": "New",
"actFinish": null,
"actHours": 0.0,
"actStart": null,
"actualResults": null,
"assigneeUserId": 0,
"customFields": [
"Test",
"test",
"tesT"
],
"id": "Test",
"name": "test",
"value": "tesT",
"description": null,
"estFinish": null,
"estHours": 0.0,
"estHrsRemaining": 0.0,
"estStart": null,
"expectedResults": null,
"folderId": 0,
"functionalAreaCode": null,
"howFoundCode": null,
"issueCode": null,
"moduleCode": null,
"pctComplete": 0,
"priorityCode": null,
"resolutionCode": null,
"severityCode": null,
"softwareVersionCode": null,
"stepsToRepro": null
}
My question is how do I write the the customFields such that it is nested correctly, as outlined in the sample JSON?

You need another POJO that represents a "CustomFields". For example:
public class CustomFields {
private String Id;
private String Name;
private String Value;
<getters and setters>
}
and use List<CustomFields> CustomFields instead of String[] customFields. Also note that your JSON example doesn't use camel case for the property names so your POJO shouldn't use camel case either.
There are ways to avoid using a POJO at all in REST Assured. You can for example use a HashMap instead which could be easier in some situations.

How to use get data using json object and display in listivew?

I have JSON like this
{
"data":
[
{
"id": 1,
"Name": "Choc Cake",
"Image": "1.jpg",
"Category": "Meal",
"Method": "",
"Ingredients":
[
{
"name": "1 Cup Ice"
},
{
"name": "1 Bag Beans"
}
]
},
{
"id": 2,
"Name": "Ice Cake",
"Image": "dfdsfdsfsdfdfdsf.jpg",
"Category": "Meal",
"Method": "",
"Ingredients":
[
{
"name": "1 Cup Ice"
}
]
}
]
}
I am using JSON Object to de-Serialize the data
this is what i am trying to
JSONObject jsonObj = new JSONObject(jsonStr);
String first = jsonObj.getJSONObject("data").getString("name");
System.out.println(first);
But a Cant seem to get the name or anything
Not sure what i am doing wrong?
and then i am trying to display it into a listview but haven't got to that part yet

data is a JSON Array, not a JSONObject
try: jsonObj.getJSONArray("data").getJSONObject(0).getString("name")
also note the difference between getString and optString, if you don't want an exception on null use the later.

First parse your Json from below method,
private ArrayList<String> getStringFromJson(String jsonStr)
{
ArrayList<String> mNames = new ArrayList<String>();
JSONArray array = new JSONArray(jsonStr);
for (int i = 0; i < array.length(); i++) {
JSONObject row = array.getJSONObject(i);
mNames= row.getString("Name");
}
return mNames;
}

try {
JSONObject jsonObj = new JSONObject(jsonStr);
jsonObj.getJSONArray("data").getJSONObject(0).getString("name")
} catch (JSONException e) {
}
Data is a json array. Use getJsonObject for json objects.
Refer to this example to create a ListView and populate it's adapter with data from a json object.

Use GSON instead JSON. Hope it helps you.
GsonBuilder gsonBuilder = new GsonBuilder();
Gson gson = gsonBuilder.create();
List<Data> datas= new ArrayList<Data>();
datas= Arrays.asList(gson.fromJson(jsonString, Data[].class));
public class Ingredients {
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
private String name;
}
public class Data {
private int id;
private String Name;
private String Image;
private String Category;
private String Method;
public List<Ingredients> getIngredients() {
return Ingredients;
}
public void setIngredients(List<Ingredients> ingredients) {
Ingredients = ingredients;
}
private List<Ingredients> Ingredients = new ArrayList<Ingredients>();
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return Name;
}
public void setName(String name) {
Name = name;
}
public String getImage() {
return Image;
}
public void setImage(String image) {
Image = image;
}
public String getCategory() {
return Category;
}
public void setCategory(String category) {
Category = category;
}
public String getMethod() {
return Method;
}
public void setMethod(String method) {
Method = method;
}
}

Java to json String ignore null values

I am creating this json string from the server as shown below and I was able to parse the string too. But when creating the json some fields like errormessage,createdDate,priority are null values. I dont want to show them in the string how can I do that?
Json Strin
{
"errormessage": null,
"createdDate": null,
"list": [{
"type": "app1",
"alternateId": "AlternateID",
"priority": null,
"description": "app for desc",
}],
"locationName": null,
"facilityManagerName": null,
"codeName": null,
"sourceKey": null,
"tablename": null,
"path": "list",
"service": "listserver",
"license": null,
"key": null,
}
expected String
{
"list": [{
"type": "app1",
"alternateId": "AlternateID",
"description": "app for desc",
}],
"path": "list",
"service": "listserver",
}
Generic Java Bean For creating the json:
public class AppObject<T> implements Serializable {
private String errormessage;
private Date createdDate;
private List<T> list;
private String locationName;
private String facilityManagerName;
private String codeName;
private Long sourceKey;
private String tablename;
private String path;
private String service;
private String license;
private Long key;
public AppObject() {
list = new ArrayList<T>();
}
public AppObject(List<T> list) {
this.list = list;
}
#XmlAnyElement(lax = true)
public List<T> getList() {
return list;
}
public void setList(List<T> list) {
this.list = list;
}
public String getLicense() {
return license;
}
public void setLicense(String license) {
this.license = license;
}
public String getPath() {
return path;
}
public void setPath(String path) {
this.path = path;
}
public String getService() {
return service;
}
public void setService(String service) {
this.service = service;
}
public String getTablename() {
return tablename;
}
public void setTablename(String tablename) {
this.tablename = tablename;
}
public String getErrormessage() {
return errormessage;
}
public void setErrormessage(String errormessage) {
this.errormessage = errormessage;
}
public Long getKey() {
return key;
}
public void setKey(Long key) {
this.key = key;
}
public String getLocationName() {
return locationName;
}
public void setLocationName(String locationName) {
this.locationName = locationName;
}
public String getFacilityManagerName() {
return facilityManagerName;
}
public void setFacilityManagerName(String facilityManagerName) {
this.facilityManagerName = facilityManagerName;
}
public Date getCreatedFeedFromDate() {
return createdFeedFromDate;
}
#JsonDeserialize(using = com.vxl.JsonDateDeserializer.class)
public void setCreatedFeedFromDate(Date createdFeedFromDate) {
this.createdFeedFromDate = createdFeedFromDate;
}
public Date getCreatedDate() {
return createdFeedToDate;
}
#JsonDeserialize(using = com.vxl.JsonDateDeserializer.class)
public void setCreatedDate(Date createdDate) {
this.createdDate = createdDate;
}
}

Honestly, I really wouldn't spend time on making a payload "look nice". Now if you said that you were motivated to keep the payload small for efficiency reasons I'd buy that.
Perhaps you use Jackson for serialising to JSON as well (I don't see why you are using two different libraries). I think that this question shows that Jackson's treatment of nulls can be controlled.

Change your get method. Set if(something!=null)return something; instead of return something;
