Question

如果有人知道回答这个问题。

我有一个错误的JSONArray无法转换为JSONObject .. 我是新手使用这个凌空图书馆

JsonArrayRequest req = new JsonArrayRequest(URL,
                new Response.Listener<JSONArray>() {
                    @Override
                    public void onResponse(JSONArray response) {
                        Log.d(TAG, response.toString());
                        try {
                            // Parsing json array response
                            // loop through each json object
                            jsonResponse = "";
                            for (int i = 0; i < response.length(); i++) {
                                JSONArray product = (JSONArray) response
                                        .get(i);
                                String productId = product.getString(Integer.parseInt("productId"));
                                String productName =product.getString(Integer.parseInt("productName"));
                                String productPrice = product.getString(Integer.parseInt("productPrice"));
                                String productImage =product.getString(Integer.parseInt("productImage"));

                                jsonResponse += "productId: " + productId + "\n\n";
                                jsonResponse += "productName: " + productName + "\n\n";
                                jsonResponse += "productPrice: " + productPrice + "\n\n";
                                jsonResponse += "productImage: " + productImage + "\n\n\n";
                        }
