org.json.JSONException：org.json.JSONObject 类型的 idddsss 中的值 {"storeid0":["1535"],"storeid1":["1862"]} 无法转换为 JSONArray

Question

我从 api

那里收到了这条回复

{"idddsss":{"storeid0":["1535"],"storeid1":["1862"]}}

这是我用来从服务器获取响应并将所有商店 ID 保存在数组中的代码：

public ArrayList<String> tripItems = new ArrayList<>();
    private void getAllStoreIds(String user_id){

        String url = Baseurl.getCartDetails+"?user_id="+user_id;

        StringRequest postStringRequest = new StringRequest(Request.Method.POST, url,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        Log.d(TAG, "ResponseCheck :" + response);
                        tripItems.clear();
                        try {
                            JSONObject jsonObject = new JSONObject(response);
                            JSONArray json = jsonObject.getJSONArray("idddsss");
                            if(json.length ()> 0){
                                for(int countItem = 0;countItem<json.length();countItem++){
                                    JSONObject o = json.getJSONObject(countItem);
                                }

                                if (!tripItems.equals(null)) {
                                    for (int i = 0; i < tripItems.size(); i++) {
                                        Toast.makeText(myContext, tripItems.get(i), Toast.LENGTH_SHORT).show();
                                    }
                                }

                            }
                        } catch (JSONException e) {
                            e.printStackTrace();
                            Toast.makeText(myContext, e.getMessage()+ "Error", Toast.LENGTH_SHORT).show();
                        }
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Toast.makeText(myContext, error.getCause().toString(), Toast.LENGTH_SHORT).show();
            }
        });

但是每当我运行代码出现以下错误时，我不知道为什么，我先将我的代码解析为 JSONObject，然后再解析为 JSONArray，然后在循环中我再次将它解析为 JSONObject。

Answer 1

idddsss 是对象，所以使用 getJSONObject 代替 getJSONArray

JSONObject objIdddsss = jsonObject.getJSONObject("idddsss");
JSONArray jsonArray = objIdddsss.getJSONArray("storeid0");
Log.v("ANS", objIdddsss.toString());
Log.v("ANS", jsonArray.toString());

org.json.JSONException：org.json.JSONObject 类型的 idddsss 中的值 {"storeid0":["1535"],"storeid1":["1862"]} 无法转换为 JSONArray

org.json.JSONException: Value {"storeid0":["1535"],"storeid1":["1862"]} at idddsss of type org.json.JSONObject cannot be converted to JSONArray
