记录显示以下错误的猫。

，这是解码json的代码。

try {

         JSONObject obj = new JSONObject(response);
         JSONArray jsonArray = obj.getJSONArray("result");

         JSONObject json_obj = jsonArray.getJSONObject(0);

          name.setText(json_obj.getString("business_name"));

          one_mobile.setText(json_obj.getString("mobile_one"));


           two_mobile.setText(json_obj.getString("mobile_two"));
           email.setText(json_obj.getString("email_id"));
           address.setText(json_obj.getString("address"));

           working_hours.setText(json_obj.getString("working_hour"));
           phone = json_obj.getString("mobile_one");

            businessrating.setText(json_obj.getString("total"));

            Glide.with(BusinessProfile.this)               .load("http://ansofexpert.com/dashboard/uploads/"+json_obj.getString("feature_image"))
                 .thumbnail(0.1f)
                 .dontAnimate()
                 .centerCrop()
                 .into(feature_image);


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

这是来自服务器的json响应

Answer 1

json_obj不包含＆＃34;总计＆＃34;在你的json字符串中。请替换以下行：

json_obj.getString("total")

与

json_obj = jsonArray.getJSONObject(1);
json_obj.getString("total")

再试一次

Answer 2

如果您格式化JSON，您将得到答案。参见

allprojects {
    repositories {
        google()
        jcenter()
        maven {url "https://maven.google.com"}
     } 
}

您可能需要这样做：

{
  "result":[
    {
        "business_id":"1",
        "business_name":"Mainland China Restaurant",
        "mobile_one":"2147483647",
        "mobile_two":"2147483647",
        "email_id":"ashishingles@rediffmail.com",
        "address":"Daultabad T Point, Daultabad Road, Sharnapur, Aurangabad - MS - 431001, Maharashtra, India",
        "area_id":"9",
        "city_name":"aurangabad",
        "establish_date":"17-05-2018",
        "about_business":"Spread over 4 acres of beautifully landscaped are for a rustic look.",
        "working_hour":"10:00 am - 10:00 pm",
        "category_id":"38",
        "subcategory_id":"2",
        "feature_image":"581e9e09692a4a6e5837b5bd89bc2877.jpg",
        "register_date":"09-05-2018",
        "expire_date":"22-05-2018",
        "status":"0"
    },
    {
        "total":"3.4"
    }
  ]
}

即使值存在，json显示错误也没有总值
