需要 Json 的帮助，我混淆了 JsonArray 和 JsonObject。我想得到 formatted_phone_number

这是我的代码。

JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, URL,
                    new Response.Listener<JSONObject>() {
                        @Override
                        public void onResponse(JSONObject response) {
                            try {
                                JSONArray jsonArray = response.getJSONArray("result");

                                for (int i = 0; i < jsonArray.length(); i++) {
                                    JSONObject result = jsonArray.getJSONObject(i);


                                    String name = result.getString("name");
                                    String formatted_phone_number= result.getString("formatted_phone_number");
                                    textView.append(name + " " + " " + formatted_phone_number+ "\n");

                                }

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

                            }
                        }
                    },
                    new Response.ErrorListener() {
                        @Override
                        public void onErrorResponse(VolleyError error) {
                            Log.e("VOLLEY ", "ERROR");
                        }
                    });
            requestQueue.add(jsonObjectRequest);

Answer 1

试试这个：

JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, URL,
                new Response.Listener<JSONObject>() {
                    @Override
                    public void onResponse(JSONObject response) {
                        try {
                             JSONObject result = response.getJSONObject("result");

                             String name = result.getString("name");
                             String formatted_phone_number= result.getString("formatted_phone_number");
                             textView.append(name + " " + " " + formatted_phone_number+ "\n");

                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        Log.e("VOLLEY ", "ERROR");
                    }
                });
        requestQueue.add(jsonObjectRequest);
