在Android中Studio中使用GET方法，排球JSON解析 [英] Parsing JSON using GET method with Volley in Android Studio

问题描述

我得到了这个 JSON 阵列：

  {
   会议：[
   {
    标识：1，
    名：Conferencia独断
    说明：Conferencia边chingona LALALA，
    扬声器：豪尔赫
    传：BIOO
    地方：{
     名：演艺厅，
     说明：presentacion德peliculasÿdocumentales
   }，
   日期：31/10/2015，
   时间：16:00
}
]
}
 

这是在我的code Android的工作室

 队列= Volley.newRequestQueue（本）;    JsonArrayRequest JsonRequest =新JsonArrayRequest（Request.Method.GET，网址，新Response.Listener＆LT; JSONArray＆GT;（）{
        @覆盖
        公共无效onResponse（JSONArray响应）{            尝试{                的for（int i = 1，计数= response.length（）; I＆LT;计数;我++）{                    EventInfo eventInfo =新EventInfo（）;
                    eventInfo.name = response.getJSONObject（I）.getString（名称）;
                    eventInfo.date = response.getJSONObject（I）.getString（DATE）;
                    eventInfo.hour_event = response.getJSONObject（I）.getString（时代）;
                    eventInfo.link =htt​​p://www.tallertoa.com/v1/files/gimgs/7_botanico-lamina-21.jpg;
                    eventInfo.description = response.getJSONObject（I）.getString（说明）;
                    eventInfos.add（eventInfo）;
                }
                  recList.setAdapter（适配器）;
                Log.e（JSON，response.toString（））;            }赶上（JSONException E）{
                showErrorDialog（错误JSON解析器，错误人parsear objeto的Json Evento）;
                Log.e（JSON错误，e.toString（））;
            }        }    }，新Response.ErrorListener（）{
        @覆盖
        公共无效onErrorResponse（VolleyError错误）{        }
    }）;
    queue.add（JsonRequest）;}
 

所以，我不能解析此JSON数组，我已经做到了这一点，但与POST方法，所以我想知道如果任何你能告诉我怎么做到这一点使用凌空

解决方案

  {
    会议：[
        {
            标识：1，
            名：Conferencia独断
            说明：Conferencia边chingona LALALA，
            扬声器：豪尔赫
            传：BIOO
            地方：{
                名：演艺厅，
                说明：presentacion德peliculasÿdocumentales
            }，
            日期：31/10/2015，
            时间：16:00
        }
    ]
}
 

首先，这是一个JSONObject，而不是一个JSONArray。你可以去 rel=\"nofollow\">和的这里更多信息

  

JSONObject的：......是开始{（左括号）和结束} （右括号）的字符串。

  
  

JSONArray：...以开始[（左括号）和结束] （右括号）的字符串。

因此​​，你可以使用 JsonObjectRequest 而不是 JsonArrayRequest

希望这有助于！

I got this json array:

  {
   "conferences": [
   {
    "id": 1,
    "name": "Conferencia Magistral",
    "description": "Conferencia bien chingona lalala",
    "speaker": "Jorge",
    "biography": "bioo",
    "place": {
     "name": "Auditorio",
     "description": "Presentacion de peliculas y documentales"
   },
   "date": "31/10/2015",
   "time": "16:00"
}
]
}

And this is my code in Android Studio:

 queue = Volley.newRequestQueue(this);

    JsonArrayRequest JsonRequest = new JsonArrayRequest(Request.Method.GET, url, new Response.Listener<JSONArray>() {
        @Override
        public void onResponse(JSONArray response) {

            try {

                for (int i = 1, count = response.length(); i < count; i++) {

                    EventInfo eventInfo = new EventInfo();
                    eventInfo.name = response.getJSONObject(i).getString("name");
                    eventInfo.date =   response.getJSONObject(i).getString("date");
                    eventInfo.hour_event =   response.getJSONObject(i).getString("time");
                    eventInfo.link="http://www.tallertoa.com/v1/files/gimgs/7_botanico-lamina-21.jpg";
                    eventInfo.description = response.getJSONObject(i).getString("description");
                    eventInfos.add(eventInfo);


                }
                  recList.setAdapter(adapter);
                Log.e("JSON", response.toString());

            } catch (JSONException e) {
                showErrorDialog("error Json parser", "error al parsear objeto Json Evento");
                Log.e("json error",e.toString());
            }

        }

    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {

        }
    });
    queue.add(JsonRequest);

}

So, i cant parse this Json Array, I've done this but with POST method, so i was wondering if any of you could tell me how to do this using volley

解决方案

{
    "conferences": [
        {
            "id": 1,
            "name": "Conferencia Magistral",
            "description": "Conferencia bien chingona lalala",
            "speaker": "Jorge",
            "biography": "bioo",
            "place": {
                "name": "Auditorio",
                "description": "Presentacion de peliculas y documentales"
            },
            "date": "31/10/2015",
            "time": "16:00"
        }
    ]
}

Firstly, this is a JSONObject, not a JSONArray. You can go here and here for more information

JSONObject: ...A string beginning with { (left brace) and ending with } (right brace).

JSONArray: ...A string that begins with [ (left bracket) and ends with ] (right bracket).

As a result, you can use a JsonObjectRequest instead of JsonArrayRequest

Hope this helps!
