無法解析JSON

Question

我是Android的初學者如何通過此JSON http://coinabul.com/api.php並顯示在主要活動的文本框中的所有catageory的美元項目，當im顯示日誌usd值顯示210三個鍵，但在json它有三個不同的值

protected void onPostExecute(InputStream result) { 
    // TODO Auto-generated method stub 
    super.onPostExecute(result); 

    progress.dismiss(); 

    String response = ConvertStreamIntoString.convertStreamToString(result); 

    Dictionary<String, Dictionary<String, String>> topDictionary = new Hashtable<String, Dictionary<String, String>>(); 
    Dictionary<String, String> innerDictionary = new Hashtable<String, String>(); 

    try { 
     JSONObject jsobject = new JSONObject(response); 
     Iterator<String> iterator = jsobject.keys(); 
     while (iterator.hasNext()) { 
      String key = iterator.next(); 
      // String value = getString(jsobject, key); 
      String v2=null; 
      JSONObject jsonObject = jsobject.getJSONObject(key); 
      Iterator<String> iterator123 = jsonObject.keys(); 
      while (iterator123.hasNext()) { 
       String keysss = (String) iterator123.next(); 
       String value = getString(jsonObject, keysss); 
       innerDictionary.put(keysss, value); 
       Log.e("innerDict",innerDictionary.toString()); 
      } 

      topDictionary.put(key, innerDictionary); 
      Log.e("asd", topDictionary.toString()); 
     } 


    } catch (JSONException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 

    context.showdata(topDictionary, innerDictionary); 
}

請找到下面的方法。你只需要在裏面傳遞響應字符串。請讓我知道如果你發現任何問題：

private void parseResponse(String response) throws JSONException { 
     Dictionary<String, Dictionary<String, String>> topDictionary = new Hashtable<String, Dictionary<String, String>>(); 


     JSONObject jsobject = new JSONObject(response); 
     Iterator<String> iterator = jsobject.keys(); 
     while (iterator.hasNext()) { 
      String key = iterator.next(); 

      JSONObject jsonObject = jsobject.getJSONObject(key); 
      Iterator<String> iterator123 = jsonObject.keys(); 
      Dictionary<String, String> innerDictionary = new Hashtable<String, String>(); 
      while (iterator123.hasNext()) { 
       String keysss = iterator123.next(); 
       String value = jsonObject.getString(keysss); 
       innerDictionary.put(keysss, value); 

      } 
      topDictionary.put(key, innerDictionary); 
     } 
     Log.v("topDictionary",topDictionary.toString());    
     showdata(topDictionary); 
    } 

private void showdata(
      Dictionary<String, Dictionary<String, String>> topDictionary) { 
     for (Enumeration e = topDictionary.keys(); e.hasMoreElements();) { 
      String keyTop = e.nextElement().toString(); 
      Log.v("keyTop",""+keyTop); 
      Dictionary<String, String> innerElements = topDictionary.get(keyTop); 
      for (Enumeration ei = innerElements.keys(); ei.hasMoreElements();) { 
       String keyInner = ei.nextElement().toString(); 
       String value = innerElements.get(keyInner); 
       System.out.println("key: "+keyInner+" value:"+value); 
       // Here you can show your values in textview 
      } 
     } 
    }
