How to print this type of json Array output in android

Question

It includes an array inside of an array

What is the android code?

This is my php output

[{"result":"true","user":[{"id":"26","name":"Manali Ashar","email":"123","password":"manali.ashar19@gmail.com","address":"chital road","city":"amreli","contact":"9402312345","qualification":"M.D","experience":"2","department":"Pediatric","age":"22","from_time":"05:15:00","to_time":"07:15:00","status":"1","current_date_time":"2016-04-02 07:18:26"}]}]

try to remove all array brackets [ ] because you need JSON Object only not array of json object. then data will look like

{"result":"true","user":{"id":"26","name":"Manali Ashar","email":"123","password":"manali.ashar19@gmail.com","address":"chital road","city":"amreli","contact":"9402312345","qualification":"M.D","experience":"2","department":"Pediatric","age":"22","from_time":"05:15:00","to_time":"07:15:00","status":"1","current_date_time":"2016-04-02 07:18:26"}}

now android code:

try {
    JSONObject json = new JSONObject(result);
    JSONObject user= json.getJSONObject("user");
    String name= user.getString("name");     
} catch (JSONException e) {
    e.printStackTrace();
}

why to remove bracketes ? – Jaimin Modi May 23 '17 at 13:17
its ok, but why dont you using JSONARRAY class to pass the actual JSON String because it contains [] brackets. no need to remove it. – Jaimin Modi May 23 '17 at 13:20
Partly true, but I think it's harder to remove the first and last bracket from a string (*also make sure you remove brackets!*), than use a JSONArray instead of a JSONObject. – Denny May 23 '17 at 13:21
@Denny nothing is harder. just we need proper knowledge about it. – Jaimin Modi May 23 '17 at 13:23
what about if you have something like this: `"data":{"1":{"id":1,"name":"Bitcoin","symbol":"BTC","category":"coin","description":"this is a description"..` Im trying to do the same but after "data": {"1":{id:1... is more difficult – Maduro Jul 24 '21 at 20:59

try {
        //send response
        JSONArray jsonArray = JSONArray(response);
        for (int i = 0; i < jsonArray.length(); i++) {
            JSONObject jsonObject = jsonArray.getJSONObject(i);
            if(!jsonObject.isNull("result")){
                String result = jsonObject.getString("result");
                if(result.equals("true")){
                    JSONArray userArray = jsonObject.getJSONArray("user");
                    for(int j=0; j<userArray.length(); j++){

String data="[{"result":"true","user":[{"id":"26","name":"Manali Ashar","email":"123","password":"manali.ashar19@gmail.com","address":"chital road","city":"amreli","contact":"9402312345","qualification":"M.D","experience":"2","department":"Pediatric","age":"22","from_time":"05:15:00","to_time":"07:15:00","status":"1","current_date_time":"2016-04-02 07:18:26"}]}]";
        try
        {
            JSONArray array=new JSONArray(data);
            JSONObject jsonObject=array.getJSONObject(0);
            String returnword=jsonObject.getString("return");
            JSONArray users=jsonObject.getJSONArray("user");
            for(int i=0;i<users.length();i++)
            {
                JSONObject object=users.getJSONObject(i);
                String id=object.getString("id");
                String name=object.getString("name");
                String email=object.getString("email");
                String password=object.getString("password");
                String address=object.getString("address");
                String city=object.getString("city");
                String contact=object.getString("contact");
                String qualification=object.getString("qualification");
                String experience=object.getString("experience");
                String department=object.getString("department");
                String age=object.getString("age");
                String from_time=object.getString("from_time");
                String to_time=object.getString("to_time");
                String status=object.getString("status");
                String current_date_time=object.getString("current_date_time");

            }
        }
        catch (JSONException e)
        {
            e.printStackTrace();
        }

This is the simple way to parse any kind of json.

You can make use of Gson library

Step 1: Create the POJO for the json data

public class Data {
    public String result;
    public List<User> user;
}

public class User {
    public String status;
    public String department;
    public String password;
    public String contact;
    public String city;
    public String id;
    public String qualification;
    public String email;
    public String address;
    public String from_time;
    public String name;
    public String age;
    public String current_date_time;
    public String experience;
    public String to_time;
}

Step 2: Parse the JSON using Gson library

final Gson gson = new Gson();

Since it's a array of data, we need to get a List like this from the json string

List<Data> response = gson.fromJson(JSON_DATA, new TypeToken<List<Data>>() {}.getType());

Step 3: Get the values

Data data = response.get(0);
User user = data.user.get(0);

And print the result likewise

Log.d("JsonExample","Name: " + user.name);
...
...
