parse Json response in retrofit

Question

The response of the call from WebService is as follows:

{
    "mobilenumber": "09999999999", 
    "service": "1" , 
    "id": "1"
}

How do I parse received Json into objects?

@Override
public void onResponse(Call<Login> call, Response<Login> response) {

    if (response.isSuccessful()) {

    } 
}

Answer 1

This code gives you how to parse the json.

    @Override
    public void onResponse(Call<Login> call, Response<Login> response) {
     if (response.isSuccessful()) {
       JSONObject jsonobject = new JSONObject(yourresponse);
       String mobilenumber = jsonobject.getString("mobilenumber");
       String service = jsonobject.getString("service");
       String id = jsonobject.getString("id");
            } 

Answer 2

By default, Retrofit can only deserialize HTTP bodies into OkHttp's ResponseBody type.

A Converter which uses Gson for serialization to and from JSON. A default Gson instance will be created or one can be configured and passed to the GsonConverterFactory to further control the serialization.

Add to gradle;

compile 'com.squareup.retrofit2:converter-gson:latest.version'


Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("https://api.xxx.com")
    .addConverterFactory(GsonConverterFactory.create())
    .build();

Assuming you have a Login model like this:

import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

public class Login {

    @SerializedName("mobilenumber")
    @Expose
    private String mobilenumber;

    @SerializedName("service")
    @Expose
    private String service;

    @SerializedName("id")
    @Expose
    private String id;

    public String getMobilenumber() {
        return mobilenumber;
    }

    public void setMobilenumber(String mobilenumber) {
        this.mobilenumber = mobilenumber;
    }

    public String getService() {
        return service;
    }

    public void setService(String service) {
        this.service = service;
    }

    public String getId() {
        return id;
    }

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

}

In your retrofit onResponse() method:

@Override
public void onResponse(Call<Login> call, Response<Login> response) {

    if (response.isSuccessful()) {

        Login loginObject = response.body();

        String mobileNumber = loginObject.getMobilenumber();
        String service = loginObject.getService();
        String id = loginObject.getId();
    } 
}
