Recyclerview is displaying entire json array instead of object

Question

Inside recyclerView everything is being displayed correctly except the "name" (Notifier > name)

When I use String creatorName = hit.getString("notifier"); it shows the entire "Notifier" object. When I use the String creatorName = hit.getString("name"); nothing is displayed.

I’m still beginner in the development world, so I don’t even know how to pick up an object from within an array of objects, if someone can give me a help I’ll be eternally grateful.

My endpoint returns me the following json:

{
"notifications":[
     { "notifier":{

 "name":"Bruno Silva"
     },
"type_text":"Te deu catch",
"avatar":"https://test.sfo2.digitaloceanspaces.com/cae31d028e5df74_avatar.jpg",
"time_text":"14:58"
}
                ]
}

And this is my mainactivity:

package com.app.contatinhos;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;

import com.android.volley.Request;
import com.android.volley.RequestQueue;
import com.android.volley.Response;
import com.android.volley.VolleyError;
import com.android.volley.toolbox.JsonObjectRequest;
import com.android.volley.toolbox.Volley;
import com.app.contatinhos.adapter.ExampleAdapter;
import com.app.contatinhos.model.ExampleItem;

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {
    private RecyclerView mRecyclerView;
    private ExampleAdapter mExampleAdapter;
    private ArrayList<ExampleItem> mExampleList;
    private RequestQueue mRequestQueue;
    private String notifier;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.fragment_four);

        mRecyclerView = findViewById(R.id.recycler_view);
        mRecyclerView.setHasFixedSize(true);
        mRecyclerView.setLayoutManager(new LinearLayoutManager(this));

        mExampleList = new ArrayList<>();

        mRequestQueue = Volley.newRequestQueue(this);
        parseJSON();
    }

    private void parseJSON() {
        String url = "https://myserver.com/api/general-data?access_token=cd7e5c9535f8167d9d47084cb5a8e6a767fdf29be5877a10532417db0c060c8517cfc5f265311178068004fef17595cd";

        JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null,
                new Response.Listener<JSONObject>() {
                    @Override
                    public void onResponse(JSONObject response) {
                        try {
                            JSONArray jsonArray = response.getJSONArray("notifications");


                            for (int i = 0; i < jsonArray.length(); i++) {
                                JSONObject hit = jsonArray.getJSONObject(i);





                                String imageUrl = hit.getString("avatar");
                                String typeText = hit.getString("type_text");



                                String creatorName = hit.getString("notifier");

                                mExampleList.add(new ExampleItem(imageUrl, creatorName, typeText));
                            }



                            mExampleAdapter = new ExampleAdapter(MainActivity.this, mExampleList);
                            mRecyclerView.setAdapter(mExampleAdapter);

                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                error.printStackTrace();
            }
        });

        mRequestQueue.add(request);
    }
}

Answer 1

Use the method getJSONObject("notifier"); to take the internal object and then use the getString("name"); to get the name of the Notifier object, see code below:

JSONObject notifierObject = hit.getJSONObject("notifier");
String creatorName = notifierObject.getString("name");

mExampleList.add(new ExampleItem(imageUrl, creatorName, typeText));
