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

上图：field2 获得值“9”，UName 按预期在文本字段上显示值“9”。

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

现在，当我使用参数调用方法时，我没有得到任何结果（意味着方法中 ID 的比较结果为假）。

但是，如果我现在这样做并调用方法，它可以完美地工作（但我不能为方法提供静态输出，它应该从用户那里获取）

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

有什么问题？如何解决？

顺便说一句，我在 kumulos 上调用一个方法，我正在为 android 编程。

编辑：我要求的确切代码。

这一切都在发生，因为您的 web 服务响应将在您的 paramage Hashmap 输入过程的代码执行之后出现。当您添加静态值时，它正在工作，因此在这种情况下，您必须在 web 服务响应之后添加数据，如下所示。 

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));
                    }
                });
            }
        });
