Question

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

上方：field2获得价值＆＃39; 9＆＃39;和UName显示价值＆＃39; 9＆＃39;在textfield上如预期的那样。

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

现在，当我使用paramage调用方法时，我得不到任何结果（意味着比较方法中的ID导致错误）。

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

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

问题是什么？如何解决？

顺便说一下我在kumulos上调用一个方法，我正在为android编程。

编辑：我提供的确切代码。

这一切都在发生，因为您的webservice响应将在您的代码执行后出现，用于paramage Hashmap输入过程。当您添加静态值时，它正在工作，所以在这种情况下，您必须在webservice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));
                    }
                });
            }
        });
