Question

我从服务器获取了一个JSON数组。但我试图访问它我得到了未终止对象异常。

我检查输出是否有任何逗号错过或错误的语法但仍无法正常工作。

JSON数组

    [
  {
    "cust_id": "8",
    "mer_id": "3",
    "fav": "1",
    "cont_name": "sandeep",
    "kirana_name": "kasar",
    "phone_no": "9422879610",
    "email_id": "kasar1@gmail.com",
    "address": "nashik"
  },
  {
    "cust_id": "8",
    "mer_id": "1",
    "fav": "1",
    "cont_name": "sandeep",
    "kirana_name": "general store",
    "phone_no": "1212345623",
    "email_id": "kasar@gmail.com",
    "address": "nashik road nashik"
  },
  {
    "cust_id": "8",
    "mer_id": "5",
    "fav": "0",
    "cont_name": "a",
    "kirana_name": "s",
    "phone_no": "9422879610",
    "email_id": "sam@gmail.com",
    "address": "aa"
  },
  {
    "cust_id": "8",
    "mer_id": "6",
    "fav": "0",
    "cont_name": "see ya",
    "kirana_name": "see ya kirana",
    "phone_no": "8698766460",
    "email_id": "deepmalasingh55@gmail.com",
    "address": "dee"
  },
  {
    "cust_id": "8",
    "mer_id": "5",
    "fav": "0",
    "cont_name": "a",
    "kirana_name": "s",
    "phone_no": "9422879610",
    "email_id": "sam@gmail.com",
    "address": "aa"
  },
  {
    "cust_id": "8",
    "mer_id": "9",
    "fav": "0",
    "cont_name": "fre",
    "kirana_name": "fee kirana",
    "phone_no": "8698766460",
    "email_id": "deepmalasinghop@gmail.com",
    "address": "plotno:12,sahaydri nagar"
  }
]

从数组中检索数据：

 @Override
    protected void onPostExecute(JSONObject response) {
        super.onPostExecute(response);
        progressDialog.dismiss();
        try {
            merchantsList.clear();
            JSONArray jsonArray = response.getJSONArray("array");
            if(jsonArray.length() > 0) {
                for (int i = 0; i < jsonArray.length(); i++) {
                    JSONObject jsonObject = jsonArray.getJSONObject(i);
                    if (jsonObject.has("message")) {
                        String message = jsonObject.getString("message");
                        Snackbar snackbar = Snackbar.make(coordinatorLayout, message, Snackbar.LENGTH_LONG);
                        snackbar.show();
                    } else {
                        long id,merchant_id,item_quantity;
                        String kirana_name,created_at,address;
                        int fav;

                         merchant_id=jsonObject.getLong("mer_id");
                        kirana_name=jsonObject.getString("kirana_name");

                        fav=jsonObject.getInt("fav");
                        address=jsonObject.getString("address");


                        Merchants merchants = new Merchants(merchant_id,kirana_name,address,fav);
                        merchantsList.add(merchants);
                        merchantsAdapter.notifyDataSetChanged();

                    }
                }

            }

例外：

出了什么问题？任何帮助都会很棒。直到你......

Answer 1

是的，这是因为您的Json数组末尾包含无效字符串。这是字符串。的 895da9a9a4cdd0825848479ee7e6c7ed2 删除它，然后重试。

修改

您可以自己检查。转到此站点Json Parser，然后将Json数组粘贴到那里。然后你会注意到一个错误。

Answer 2

您的JSON中没有像"array"这样的元素，您正在使用它。 JSON应该为每个值都有一些键。

JSONArray jsonArray = response.getJSONArray("array");

在这种情况下，您的JSON数组应该有"array"=[]
