问题描述

这是低于我如何接取这个JSON文件检查我的方法是coreect方法尖子JSON文件阵列和节点我的code？我想接取从我的code低于这个JSON文件帮助我我怎么接取这个JSON文件formmy code？我dontknow的howmany阵列中的JSON文件

  {
    状态：1，
    信息：，
    数据：
    {
        学校：
        [
        {
            ID：3，
            名：FG公立学校
        }，
        {
            ID：4，
            名：Fazaia国际学院}
        ]
    }
}
HttpClient的客户端=新DefaultHttpClient（）;HttpConnectionParams.setConnectionTimeout（client.getParams（），15000）;HttpConnectionParams.setSoTimeout（client.getParams（），15000）;
HttpUriRequest要求=新HTTPGET（SelectMenuAPI）;
HTT presponse响应= client.execute（请求）;
InputStream的atomInputStream =
。response.getEntity（）的getContent（）;
在的BufferedReader =新的BufferedReader（新
InputStreamReader的（atomInputStream））;串线;
字符串str =;
而（（行= in.readLine（））！= NULL）{
    STR + =行;
}
JSONObject的JSON =新的JSONObject（STR）;
JSONArray数据= json.getJSONArray（学校）;的for（int i = 0; I＆LT; data.length（）;我++）{
    的JSONObject对象=
    data.getJSONObject（ⅰ）;    //类的JSONObject =
    object.getJSONObject（类别）;
    Category_ID.add（的Long.parseLong（object.getString（ID）））;    Category_name.add（object.getString（名字））;    Log.d（类别名称，
    Category_name.get（ⅰ））;
 

解决方案

该类别的对象不是JSON文件内present

您可以尝试以下

  JSONObject的JSON =新的JSONObject（STR）;
    JSONObject的数据= json.getJSONObject（数据）;
    JSONArray学校= json.getJSONArray（学校）;    的for（int i = 0; I＆LT; data.length（）;我++）{
        的JSONObject对象= school.getJSONObject（I）        长ID =的Long.parseLong（object.getString（ID））;
        字符串名称= object.getString（名称）;
        JSONObject的类别=新的JSONObject（）;
                    category.put（ID）;
                    category.put（名称）;
    }
 

this is my code below how do i acess this json file check my method it is coreect method to aces json file array and nodes? i want to acess this json file below from my code help me how do i acess this json file formmy code? i dontknow howmany array in json file

{
    "status":1,
    "message":"",
    "data":
    {
        "school":
        [
        {
            "id":3,
            "name":"FG Public School"
        },
        {
            "id":4,
            "name":"Fazaia Inter College"}
        ]
    }
}




HttpClient client = new DefaultHttpClient();

HttpConnectionParams.setConnectionTimeout(client.getParams(), 15000);

HttpConnectionParams.setSoTimeout(client.getParams(), 15000);
HttpUriRequest request = new HttpGet(SelectMenuAPI);
HttpResponse response = client.execute(request);
InputStream atomInputStream = 
response.getEntity().getContent();
BufferedReader in = new BufferedReader(new 
InputStreamReader(atomInputStream));

String line;
String str = "";
while ((line = in.readLine()) != null){
    str += line;
}


JSONObject json = new JSONObject(str);
JSONArray data = json.getJSONArray("school");

for (int i = 0; i < data.length(); i++) {
    JSONObject object =  
    data.getJSONObject(i); 

    //    JSONObject category = 
    object.getJSONObject("Category");


    Category_ID.add(Long.parseLong(object.getString("id")));

    Category_name.add(object.getString("name"));

    Log.d("Category name", 
    Category_name.get(i));

解决方案

The Category object is not present inside the Json file

you can try following

    JSONObject json = new JSONObject("str");
    JSONObject data = json.getJSONObject("data");
    JSONArray school = json.getJSONArray("school");

    for (int i = 0; i < data.length(); i++) {
        JSONObject object = school.getJSONObject(i);

        long id = Long.parseLong(object.getString("id"));
        String name = object.getString("name");
        JSONObject category = new JSONObject();
                    category.put("id");
                    category.put("name");




    }
