Volley Post request ,Send Json object in Json array request

Question

To say in simple words i want to send this {"Id":7,"Name":"MyName"} data To server using Volley Post Request.

It has 1 integer and 1 String and response i get is Jsonarray

I tried Following ways but none are working

• as it is json array request i cannot send data in argument as 3rd argument only takes JsonArray and i have to send JsonObject so kept it as null

  new JsonArrayRequest(Method,Url,JsonArray,ResponseListener,ErrorListner)

• I cannot put it in HashMap as 1 of the value is integer, and it only accepts string

getparams() method

@Override
protected Map<String, String> getParams() throws AuthFailureError {
    Map<String,String> params=new HashMap<>();
    params.put("Id",7); //            <====== This is Invalid
    params.put("Name","MyName");
    return params;
}

• I tried to send in getbody method ,still not working

getbody method

@Override
public byte[] getBody() {
    String body="{\"Id\":7,\"Name\":\"MyName\"}";
    return body.getBytes();
}

I can get the response using HttpUrlConnection.

Is there any other way to achieve it in volley ?

Thanks to akash93 , i finally did it .Here is how to do it

write a class MyJsonArrayRequest.java like below

import com.android.volley.NetworkResponse;
import com.android.volley.ParseError;
import com.android.volley.Response;
import com.android.volley.toolbox.HttpHeaderParser;
import com.android.volley.toolbox.JsonRequest;

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

import java.io.UnsupportedEncodingException;
public class MyJsonArrayRequest extends JsonRequest<JSONArray> {


    public MyJsonArrayRequest(int method, String url, JSONObject jsonRequest,
                              Response.Listener<JSONArray> listener, Response.ErrorListener errorListener) {
        super(method, url, (jsonRequest == null) ? null : jsonRequest.toString(), listener,
                errorListener);
    }

    @Override
    protected Response<JSONArray> parseNetworkResponse(NetworkResponse response) {
        try {
            String jsonString = new String(response.data,
                    HttpHeaderParser.parseCharset(response.headers, PROTOCOL_CHARSET));
            return Response.success(new JSONArray(jsonString),
                    HttpHeaderParser.parseCacheHeaders(response));
        } catch (UnsupportedEncodingException e) {
            return Response.error(new ParseError(e));
        } catch (JSONException je) {
            return Response.error(new ParseError(je));
        }
    }

usage :

 MyJsonArrayRequest request=new MyJsonArrayRequest(Request.Method.POST, Constants.SEARCH_PROFILE, object, new Response.Listener<JSONArray>() {
        @Override
        public void onResponse(JSONArray response) {

            Log.i("onResponse", ""+response.toString());
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            error.printStackTrace();
            Log.i("onErrorResponse", "Error");
        }
    });

even more easier way is to override getBody() which should work , but some way it didn't work for me first time.

 @Override
public byte[] getBody() {
    String body="{\"Id\":7,\"Name\":\"MyName\"}";
    return body.getBytes();
}
