Integer.toString（）更改int的值

Question

private int ID=0; 
. 
. 
Integer field2=0; 
field2 = Integer.parseInt(item.get("credentialID").toString()); 
ID=field2.intValue(); 
UName.setText(Integer.toString(ID)); 

上面的內容：根據預期，field2的值爲'9'，UName在文本字段顯示值'9'。

HashMap<String,String> paramage= new HashMap<String, String>(); 
paramage.put("credential", Integer.toString(ID)); 

現在，當我調用使用paramage的方法時，我沒有得到任何結果（意味着方法中的ID比較導致false）。

但是，如果我這樣做，並調用方法現在，它完美的作品（但我無法提供靜態輸出方法，應該從用戶採取）

HashMap<String,String> paramage= new HashMap<String, String>(); 
paramage.put("credential", "9"); 

什麼問題？如何解決它？

順便說一句我打電話給kumulos的方法，我正在爲android編程。

編輯：我的確切代碼按要求。

這一切都是因爲你的web服務響應遲來了，然後你的代碼執行paramage Hashmap輸入過程。當你添加靜態值時，它正在工作，所以在這種情況下，你必須在下面的webservice響應之後添加數據。

HashMap<String,String> paramage= new HashMap<String, String>(); 

Kumulos.call("login", params, new ResponseHandler() { 
      @Override 
      public void didCompleteWithResult(Object result) { 

       Integer field2 = 0; 
       ArrayList<LinkedHashMap<String, Object>> objects = (ArrayList<LinkedHashMap<String, Object>>) result; 
       LinkedHashMap<String, Object> item = objects.get(0); 
       field2 = Integer.parseInt(item.get("credentialID").toString()); 
       ID = field2.intValue(); 
       UName.setText(Integer.toString(ID)); 

       paramage.put("credential", Integer.toString(ID));  //up here 

       //As you are making web service call for "getage" so I put this code here. You can make a callback to write this code outside for "getage" webservice call. 
       Kumulos.call("getage", paramage, new ResponseHandler() { 
        @Override 
        public void didCompleteWithResult(Object result) { 
         Integer field2 = 0; 
         ArrayList<LinkedHashMap<String, Object>> objects = (ArrayList<LinkedHashMap<String, Object>>) result; 
         LinkedHashMap<String, Object> item = objects.get(0); 
         //Boolean check = item.containsKey("age"); 
         field2 = Integer.parseInt(item.get("age").toString()); 
         int age = field2.intValue(); 
         UAge.setText(Integer.toString(age)); 
        } 
       }); 
      } 
     });
