在另一个JsonObject中提取JsonObject

Question

我想从我从API接收的JSON数据中提取数据。
我知道如何从Jsonarray中检索简单的jsonArray数据或JsonObject，但我是JSON嵌套的新手。

如何提取此数据？

{ 
    "call_log": { 
     "7837369400": { 
      "7000011216180827872": { 
       "start_date": "01 Dec 2014", 
       "start_time": "06:08 PM", 
       "end_date": "01 Dec 2014", 
       "end_time": "06:10 PM", 
       "call_sdate": "2014-12-01 18:08:27.000", 
       "call_edate": "2014-12-01 18:10:03.000", 
       "call_type": "1", 
       "caller": "0000000000", 
       "duartion": "94", 
       "call_duartion": "01:34", 
       "dtmf": "NA", 
       "dt_number": "0000000000", 
       "recording_path": "28.wav", 
       "agent_mobile": "0000000000", 
       "agent_name": "something" 
      }, 
      "7000301116163015079": { 
       "start_date": "30 Nov 2014", 
       "start_time": "04:30 PM", 
       "end_date": "30 Nov 2014", 
       "end_time": "04:31 PM", 
       "call_sdate": "2014-11-30 16:30:15.000", 
       "call_edate": "2014-11-30 16:31:14.000", 
       "call_type": "1", 
       "caller": "0000000000", 
       "duartion": "59", 
       "call_duartion": "00:59", 
       "dtmf": "NA", 
       "dt_number": "0000000000", 
       "recording_path": "30.wav", 
       "agent_mobile": "0000000000", 
       "agent_name": "something" 
      } 
     } 
    } 
} 

我想要的代码是：

try { 
    JSONObject jObject= new JSONObject(response).getJSONObject("call_log"); 
    Iterator<String> keys = jObject.keys(); 
    while(keys.hasNext()) 
    { 
     String key = keys.next(); 
     // __________________________ 

     // __________________________ 
     Log.v("**********", "**********"); 
     Log.v("category key", key); 


     // JSONObject jO= new JSONObject(response).getJSONObject(key); 
     // Log.v("next is", jO.toString()); 
     // JSONObject innerJObject = jObject.getJSONObject(key); 

     // String name = innerJObject.getString("start_date"); 
     // String term_id = innerJObject.getString("start_time"); 

     //Log.v("name = "+name, "term_id = "+term_id); 

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

Answer 1

如果我读了JSON正确...

1）获取通话记录
2）获取的数字
3）获取该号码的条目
4）从该条目获取值

JSONObject responseObject = new JSONObject(response); 
JSONObject callLog = responseObject.getJSONObject("call_log"); // 1 

Iterator<String> phoneNumbers = callLog.keys(); // 2 

while(phoneNumbers.hasNext()) { 
    JSONObject numberLog = callLog.getJSONObject(phoneNumbers.next()); 
    Iterator<String> callEntries = numberLog.keys(); // 3 

    while(callEntries.hasNext()) { 
     JSONObject entry = numberLog.getJSONObject(callEntries.next()); 

     // 4 
     String name = entry.getString("start_date");
