如何从 Volley Api 字符串响应中查找特定数据

Question

I am new to APIs and finally figured out how to successfully retrieve a request response from a website. The thing is I am completely lost on how I should handle the response. I don't know how to access certain values within the response

here is my API Volley code

  RequestQueue requestQueue = Volley.newRequestQueue(this);
    String uri = Uri.parse("https://chicken-coop.p.rapidapi.com/games/Fortnite?platform=pc")
            .buildUpon()
            .build().toString();

    StringRequest stringRequest = new StringRequest(
            Request.Method.GET, uri, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            displayResults.setText("Response: " + response.substring(0,500));

        }

    }, new Response.ErrorListener() {

        @Override
        public void onErrorResponse(VolleyError error) {
             displayResults.setText( "" + error.toString());
        }

    }) {

        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            Map<String, String> params = new HashMap<>();
            params.put("X-RapidAPI-Key", "5cdb2bbe57mshd9242c8d3177cb3p16f2fbjsnd7c5829eb4ad");
            params.put("X-RapidAPI-Host", "chicken-coop.p.rapidapi.com");
            return params;
        }
    };
    requestQueue.add(stringRequest);

Here is the response query that I received

"result":{10 items "title":"Fortnite" "releaseDate":"Jul 25, 2017" "description":"Epic Games next project has you building forts and stopping a zombie invasion." "genre":[... ]6 items "image":" https://static.metacritic.com/images/products/games/5/c7eb46ceb7da9c72c5a95193e8621faf-98.jpg " "score":81 "developer":"Epic Games" "publisher":[... ]1 item "rating":"T" "alsoAvailableOn":[6 items 0: "iPhone/iPad" 1: "PlayStation 3" 2: "PlayStation 4" 3: "Switch" 4: "Xbox 360" 5: "Xbox One"

How would I go about finding an explicit value from the response query ? I have been searching for how to do this online and there are so many different ways to go about and I have no clue what to do. For example, how would I be able to put the Release Date into its own text box? Most of the examples I see online use JsonObjects when I m using a string response

Answer 1

in your onResponse method you need to parse your result so you can extract any data you want

public void onResponse(String response) {
        try {
            JSONObject jsonObject = new JSONObject(response);
            JSONArray jsonArray = jsonObject.getJSONArray("result");
             // toaccess to your json data 
                String title = jsonArray.getString("title");
                // your code 


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