Android中关于读取JSON数组的问题

我在读取一个JSON数组：

JSONArray jArray = new JSONArray(jsonString);        System.out.println(""*****JARRAY*****""+jArray.length());        for(int i=0;i<jArray.length();i++){                JSONObject json_data = jArray.getJSONObject(i);                Log.i(""log_tag""_id""+json_data.getInt(""account"")+ mall_name""+json_data.getString(""name"")+ location""+json_data.getString(""number"")+ telephone""+json_data.getString(""url"")+----""+json_data.getString(""balance"")+----""+json_data.getString(""credit"")+----""+json_data.getString(""displayName"")                );        }

JSON语法文件的案例如下：

<code>{list"": [        {account"": 1name"": ""card""number"": ""xxxxx xxxx xxxx 2002""url"": ""http://www.google.com""balance"": 1.0credit"": 1.0displayName"": ""hsbc bank""         }        {account"": 2name"": ""card2""number"": ""xxxxx xxxx xxxx 3003""url"": ""http://www.google.com""balance"": 2.0credit"": 2.0displayName"": ""nsb bank""         }     ]count"": 2}</code>

语法前面都有一个花括号。当我执行这些代码块时，系统会报错说：

A JSONArray text must start with '[' at character 1 of....

有谁遇见过这样的问题吗？能提供案例的代码块更好，不胜感激~~

解决方案

<string name=""json_array"">    {""calendar"":         {""calendarlist"":             [             {""calendar_id"":""1705""title"":""(u4eb2u5b50)ddssd""category_name"":""u9ed8u8ba4u5206u7c7b""showtime"":""1288927800""endshowtime"":""1288931400""allDay"":false}             {""calendar_id"":""1706""title"":""(u65c5u884c)""category_name"":""u9ed8u8ba4u5206u7c7b""showtime"":""1288933200""endshowtime"":""1288936800""allDay"":false}             ]         }     }  </string>

解析代码：

public void parseJsonArray(String string){    try {        JSONObject jsonObject = new JSONObject(string).getJSONObject(""calendar"");        JSONArray jsonArray = jsonObject.getJSONArray(""calendarlist"");        StringBuffer sb = new StringBuffer();        for(int i = 0;i < jsonArray.length();i ++){            JSONObject json = (JSONObject) jsonArray.opt(i);            String calendar_id = json.getString(""calendar_id"");            String title = json.getString(""title"");            String category_name = json.getString(""category_name"");            String showtime = json.getString(""showtime"");            String endshowtime = json.getString(""endshowtime"");            String allDay = json.getString(""allDay"");            sb.append(""calendar_id: "" + calendar_id + ""nn"" + ""title: "" + title + ""nn"" + category_name: "" + category_name + ""nn"" + ""showtime: "" + showtime + ""nn"" + endshowtime: "" + endshowtime + ""nn"" + ""allDay: "" + allDay + ""nn"" + -------------------------------------nn"");        }        text.setText(sb.toString());    } catch (JSONException e) {        e.printStackTrace();    }}
