JSON parsing without array name or node in Android

Question

I have a JSOn array without array name and I'm confused how to parse it and how to make JSONObject or JSONArray. If possible then please describe it.

My JSON Array list is:

[{
name:"Product_fill",
image:"https://something.com/product1.jpg",
title:"Laptop 1"
},
{
name:"Product_fill2",
image:"https://something.com/product2.jpg",
title:"Laptop 2"
},

and my code is :

    RequestQueue queue= Volley.newRequestQueue(this);
        String Url="http://msomething.com/list.php";
        StringRequest request=new StringRequest(Request.Method.GET, Url, new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                //weatherData.setText("Response is :- ");
                parseData(response);
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                textView.setText("Data Not Received");

            }
        });

        queue.add(request);
        super.onStart();


    }

    private void parseData(String response) {
        try {
            // Create JSOn Object
           JSONObject jsonObject=new JSONObject(response);
           JSONObject main=jsonObject.getJSONObject("array");
        JSONArray jsonArray=jsonObject.getJSONArray("0");

 for(int i=0;i<jsonArray.length();i++)
            {
JSONObject jsonObject1=jsonArray.getJSONObject(i);
textView.setText(jsonObject1.getString("name"));

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

You can pass the response string to the JSONArray constructor directly and then parse the array using a loop

JSONArray jsonArray = new JSONArray(response);

Tip: I would search how to use other json libraries like Gson or Jackson as the Android built-in parser is not good.

Try this:

 try {
      JSONArray jsonArray = new JSONArray(response);
      for (int i = 0; i <jsonArray.length() ; i++) {
     JSONObject jsonObject = (JSONObject) jsonArray.get(i);  
     textView.setText(jsonObject.getString("name"));   
     }    
    } catch (JSONException e) {
      e.printStackTrace();
   }
