Get Json Array in Post Retrofit

Get Json Array in Post Retrofit - java

I have a problem when I want to retrieve an array from a post response
this is my post
{
"user_email": "xxxx#gmail.com",
"user_password": "12345"
}
and this is my post response , I want get the token value
{
"status": true,
"code": 200,
"message": "Request Succeded: Login success",
"data": [
{
"token": "bsWIVXTLuud2ZbdnUvI8037fT7D0t7MTvusBrNjskah"
}
]
}
this is my model LoginModel.java
#SerializedName("data")
#Expose
private Data data ;
public Data getData() {
return data;
}
public void setData (Data data) {
this.data = data;
}
public LoginModel(String user_email, String user_password) {
this.user_email = user_email;
this.user_password = user_password;
}
Data.java
public String getToken() {
return token;
}
public void setToken(String token) {
this.token = token;
}
there code I'm tried before ,the text view show nothing
LoginModel loginModelresponse = response.body();
String token = loginModelresponse.getData().getToken();
textView.setText(token);
I want get the token from my post response.

Your data value is an array of tokens, not an object itself
Create a Token class with a token String field, then replace the Data class like so
#SerializedName("data")
#Expose
private List<Token> data ;
To get the token, you must iterate the list

Try to change your LoginModel class, because your response data object is Array type
public class LoginModel {
#SerializedName("status")
#Expose
private Boolean status;
#SerializedName("code")
#Expose
private Integer code;
#SerializedName("message")
#Expose
private String message;
#SerializedName("data")
#Expose
private List<Data> data = null;
public Boolean getStatus() {
return status;
}
public void setStatus(Boolean status) {
this.status = status;
}
public Integer getCode() {
return code;
}
public void setCode(Integer code) {
this.code = code;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public List<Data> getData() {
return data;
}
public void setData(List<Data> data) {
this.data = data;
}
}

use this site to generate a correct response class in java
public class Tokens implements Serializable
{
#SerializedName("token")
#Expose
private String token;
private final static long serialVersionUID = 1577013820593763604L;
public String getToken() {
return token;
}
public void setToken(String token) {
this.token = token;
}
}

What is the problem
My error code ("expected begin_array but was begin_object")
I can't find out what the problem is in these codes and the data doesn't come in response and gives an error instead

As you can see in JSON response, errors and parameters are comes as List.
So please change fields to list in Covid19Model
#SerializedName("parameters")
#Expose
private List<Parameters> parameters;
#SerializedName("errors")
#Expose
private List<Errors> errors;

Here are the classes which are generated from the Response which you have provided in the question.
You can use this link to generate the POJO class for JSON response.
JSON TO POJO
Add this gradle:
implementation 'com.google.code.gson:gson:2.8.2'
Init the Gson buildr:
private Gson gson;
GsonBuilder gsonBuilder = new GsonBuilder();
gsonBuilder.setDateFormat("M/d/yy hh:mm a");
gson = gsonBuilder.create();
Parse the JSON using GSON
gson.fromJson(jsonObject.getJSONObject("data").toString(), Example.class);
These are the basic steps to parse the JSON using GSON.
For more information you can refer to the below article:
Parsing JSON on Android using GSON
Or Check the GSON official GitHub Repository
GSON

How to Convert JSON to POJO class?

I checked the following json, it is valid, But http://www.jsonschema2pojo.org/ is not converting it into POJO object so I can fetch values from it, I need "nameValuePairs" object in following model. Please help. Thanks in advance
[
"order-chat-1",
{
"nameValuePairs":{
"chat":{
"nameValuePairs":{
"id":19,
"order_id":6,
"sender_id":10,
"receiver_id":3,
"message":"Hi",
"is_read":0,
"created_at":"2018-10-19 16:23:28",
"updated_at":"2018-10-19 16:23:28",
"is_sender":false
}
},
"message":"Hello from chef",
"message_type":"Message",
"is_sender":false
}
}
]

Here is the code to put on http://www.jsonschema2pojo.org/
{
"type":"object",
"properties":{
"chat":{
"type":"object",
"properties":{
"nameValuePairs":{
"type":"object",
"properties":{
"id": {"type": "integer"},
"order_id":{"type": "integer"},
"sender_id":{"type": "integer"},
"receiver_id":{"type": "integer"},
"message":{"type": "string"},
"is_read":{"type": "integer"},
"created_at":{"type": "string"},
"updated_at":{"type": "string"},
"is_sender":{"type": "boolean"}
}
}
}
},
"message":{"type": "string"},
"message_type":{"type": "string"},
"is_sender":{"type": "boolean"}
}
}
That produces the following POJO's where Example.class is your root object, change the name as you want.

It is valid from JavaScript prospective, but not form standard Java libraries such as GSON, Jackson or whatever www.jsonschema2pojo.org uses.
There are two things:
It is an Array on top
There are two different types in that array String and an Object
It can be converted only to Object[] or Collection<Object> (e.g.List, Set etc).
But to do that you have to have a custom Serializer/Deserializer.

I worked with another technique to resolve this, I converted this Object to String through Gson() and after that with subString method I removed the first 16 characters and the last character of the newly created string, then I Converted that String to POJO Object.

Gson deserialization Expected BEGIN_ARRAY but was STRING [duplicate]

I get the following json response from my api in my android application, i am using Gson deserialization to parse my data and populate my listview.

How can i convert json string to java object in android?

I am trying to convert the response from server which is a JSON string,I want to convert that JSONstring to java object.I am trying Gson.Please someone explain and tell me the steps how to do it using Gson.

You can use in a generic way like:
private final static Gson GSON = new GsonBuilder().create();
public static <T> T fromJSON(String json, Class<T> clazz) {
try {
return GSON.fromJson(json, clazz);
} catch (JsonSyntaxException e) {
LOGGER.warn("Could not deserialize object", e);
}
return null;
}

You can't make activity/fragment from json.
In your onResponse() method:
ModelObject obj = new Gson().fromJson(jsonString, ModelObject.class);
And make ModelObject class something like this:
public class ModelObject {
int field1;
int field2;
//here you should make getters and setters;
}
After it you can do anything you need with this object (pass it to any activity or fragment).

Gson will map the values to the corresponding model class object if the fields are given correctly. Have a look at the below model classes. After that, if you call Example data = GSON.fromJson(yourJson, Example.class); , this data object will have all that you need.

Get Json Array in Post Retrofit - java

Your data value is an array of tokens, not an object itself Create a Token class with a token String field, then replace the Data class like so #SerializedName("data") #Expose private List<Token> data ; To get the token, you must iterate the list
