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));

上圖：field2獲得值“ 9”，UName按預期在文本字段上顯示值“ 9”。

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

現在，當我使用參數調用方法時，我沒有任何結果（方法中ID的比較結果為false）。

但是，如果我現在執行此操作並調用方法，則它可以正常工作（但是我無法向方法提供靜態輸出，應從用戶那里獲取）

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

有什么問題？ 如何解決？

順便說一句，我在kumulos上調用一個方法，並且我正在為android編程。

編輯：我要求的確切代碼。

這一切都在發生，因為您的Web服務響應稍后出現，然后您將執行參數Hashmap輸入過程的代碼。 當您添加靜態值時，它就起作用了，因此在這種情況下，您必須在如下所示的Web服務響應之后添加數據。

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));
                    }
                });
            }
        });
