我有一个json链接,如果我们打开它,我会得到以下结果

{
"Status": "Success",

"All_Details": [{
    "Types": "0",
    "TotalPoints": "0",
    "ExpiringToday": 0
}],
"First": [{
    "id": "0",
    "ImagePath": "http://first.example.png"
}],
"Second": [{
    "id": "2",
    "ImagePath": "http://second.example.png"
}],
"Third": [{
    "id": "3",
    "ImagePath": "http://third.example.png"
}],

}

我需要的是,我想动态获取所有关键名称,如status,All_details,First等.

我还想在All_details和First Array中获取数据.我使用以下方法

@Override
        public void onResponse(JSONObject response) throws JSONException {
            VolleyLog.d(TAG, "Home Central OnResponse: " + response);

            String statusStr = response.getString("Status");
            Log.d(TAG, "Status: " + statusStr);

            if (statusStr.equalsIgnoreCase("Success")) {
                Iterator iterator = response.keys();
                while (iterator.hasNext()) {
                    String key = (String)iterator.next();
                }
            }
        }

我得到了存储在String键中的所有键名.但是我无法打开获取JSON数组中的值,例如.我需要使用String(Key)获取第一个和第二个数组中的值.我怎样才能做到这一点.？？？

我有以下 JSON 数据：

[
    {
        "sendingReqDataSet": {
            "totalCount": 1,
            "limit": 50,
            "offset": 0,
            "status_code": true,
            "contacts": [
                {
                    "id": 1,
                    "request_to": "Shehla_kiran",

                    "status": "Pending"
                },
                {
                    "id": 2,
                    "request_to": "muqadas",

                    "status": "Pending"
                },
                {

                    "place": "Lahore",
                    "request_type": "Swap",
                    "status": "Pending"
                },
                {
                    "id": 4,
                    "request_to": "Shehla_kiran", …

JsonParse.Java试图从URL获取json数组对象,但它抛出了Parsing ERROR,
而CountriedBean是我的POJO类.
parse_json只有ListView,而parse_json_view有4个TextView

任何人都可以帮助我................

private List<CountriesBean> cntries= new ArrayList<CountriesBean>();
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.parse_json);

            RequestQueue queues = Volley.newRequestQueue(JsonParse.this);

            JsonObjectRequest myRequest = new JsonObjectRequest(Request.Method.GET,
                    "https://github.com/SaiNitesh/REST-Web-services/blob/master/RESTfulWS/json_file.json",
                    null,
                    new Response.Listener<JSONObject>() {
                        @Override
                        public void onResponse(JSONObject response) {
                            try{
                                Log.i("myCountries**", "response:" +response);
                            JSONArray countryItems = response.getJSONArray("countryItems");

                            Log.i("myTagx", "response:" +countryItems);

                                for(int i=0; i<countryItems.length();i++){
                                    JSONObject temp= countryItems.getJSONObject(i);

                                    String nm = temp.getString("nm");
                                    String cty = temp.getString("cty");
                                    String hse = temp.getString("hse");
                                    String yrs = temp.getString("yrs");

                                    cntries.add(new CountriesBean(nm, cty, hse, yrs));
                                }
                            } catch(JSONException e){ …

我想"result"从下面的JSON响应中获取值并将其存储在本地.这是代码:

private class GetContacts extends AsyncTask<Void, Void, Void> {

        @Override
        protected Void doInBackground(Void... arg0) {
            // Creating service handler class instance
            ServiceHandler sh = new ServiceHandler();

            // Making a request to url and getting response
            String jsonStr = sh.makeServiceCall(url, ServiceHandler.GET);

            if (jsonStr != null) {
                    try {
                        JSONObject jsonObj = new JSONObject(jsonStr);

                        //JSONArray contacts;
                        contacts = jsonObj.getJSONArray("response");
                        Log.d("Response: ", "> " + contacts);

                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                } else {
                    Log.e("ServiceHandler", "Couldn't get any data …
