Question

JSON对象，我有这个代码试图从JSON对象中提取电子邮件

JSONArray one = reader.getJSONArray("taxis"); 

for (i = 0; i < one.length(); i++) { 
    two = one.getJSONObject(i); 
    distance = two.getString("taxis"); 
    three = two.getJSONArray("taxis"); 
     for (j = 0; j < three.length(); j++) { 
      four = three.getJSONObject(j); 
      distance = four.getString("email"); 
     } 
    } 

我得到JSON结果这样

{ 
    "taxis": [ 
    { 
     "taxis": { 
     "id": "1", 
     "email": "thamaraiselvam@live.com", 
     "password": "0cc175b9c0f1b6a831c399e269772661", 
     "name": "Thamaraiselvam" 
     } 
    }, 
    { 
     "taxis": { 
     "id": "3", 
     "email": "arunesh@snowmanbranding.com", 
     "password": "3bf575512fdce89fd4e3ba87a230b2f4", 
     "name": "Arunesh" 
     } 
    }, 
    { 
     "taxis": { 
     "id": "4", 
     "email": "a@a.com", 
     "password": "0cc175b9c0f1b6a831c399e269772661", 
     "name": "A" 
     } 
    } 
    ] 
} 

如何提取电子邮件，使用Android的密码和名称？ 我没有得到任何东西，当我上面的几个JSON解析库代码

Answer 1

JSONArray albums = reader.getJSONArray("map"); 

      // looping through All albums 
      for(j= 0; j < albums.length(); j++){ 
       JSONObject codes = albums.getJSONObject(j); 

       String album_id = codes.getString("location"); 

       album_id="["+album_id+"]"; 
       JSONArray jsonArray = new JSONArray(album_id); 
       for(k= 0; k < jsonArray.length(); k++){ 
        JSONObject codess = jsonArray.getJSONObject(k); 

     distance[k] = codess.getString("id"); 
      } 
      }
