解析多層JSON

Question

我想解析多級JSON（來自Quandl），但我有困難解析它正確。

我無法弄清楚如何解析的部分在數據標籤下。如何選擇它並遍歷所有值，因爲它們不是密鑰對。

這部分代碼需要int

stockArray.getJSONArray("data"); 

任何幫助是非常讚賞。

這是我現在想：

JSONObject stockObject = new JSONObject(result); 
      JSONArray stockArray = stockObject.getJSONArray("dataset"); 
      JSONArray statsArray = stockArray.getJSONArray("data"); 
      for(int i = 0; i < statsArray.length(); i++){ 
       JSONArray arr = statsArray.getJSONArray(i); 
       for(int j = 0; j < arr.length(); j++){ 
        Log.d("TAG", arr.getString(j)); 
       } 
      } 

這是JSON：

    "dataset":{ 
     "id":9792521, 
     "dataset_code":"KIBO", 
     "database_code":"LSE", 
     "name":"KIBO MINING share price (KIBO), Currency GBX",

Answer 1

你有數據陣列內的另一個數組。

該代碼將記錄每一個元素：

JSONObject rootObject = new JSONObject(result); 
    JSONObject stockObject = rootObject.getJSONObject("dataset"); 
    JSONArray statsArray = stockObject.getJSONArray("data"); 
    for(int i = 0; i < statsArray.length(); i++){ 
     JSONArray arr = statsArray.getJSONArray(i); 
     for(int j = 0; j < arr.length(); j++){ 
      Log.d("TAG", arr.getString(j)); 
     } 
    }
