Java Question

Integer.toString() changes value of int

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


Above: field2 gets value '9' and UName shows value '9' on textfield as expected.

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


Now when i call method using paramage i get no result (means comparison of ID in method resulted false).

However, if I do this and call method now,it works flawlessly (but I can't provide static output to method ,it should be taken from user)

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


What's the problem? How to Solve it?

Btw I am calling a method on kumulos and I am programming for android.

EDIT: My exact code as requested.

public class MainActivity extends AppCompatActivity {

try {

ID = (int) result;
}
});
UName.setText("");
UPass.setText("");
params.put(UAge.getText().toString(), Integer.toString(ID));
Kumulos.call("setAge", params, new ResponseHandler() {
@Override
public void didCompleteWithResult(Object result) {


}
});
UAge.setText(Integer.toString(ID));

}
catch (Exception e)
{
UAge.setText("5");
e.printStackTrace();
}

}
});
}

}


Code after signup Button declaration is not tested and edited dont look there.

Answer

This all is happening because your webservice response is coming later then your code execution for paramage Hashmap input process. When you are adding static value then it is working so in this case you have to add data after webservice response like below.

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));
                    }
                });
            }
        });
