            if(login_cb_user.Checked)
            {
                ISharedPreferences prefs = PreferenceManager.GetDefaultSharedPreferences(this);
                ISharedPreferencesEditor editor = prefs.Edit();
                editor.PutBoolean("Ck_Status", true);
                editor.PutString("UserName", UserName);
                editor.Commit();
                editor.Apply();
            }
            else
            {
                ISharedPreferences prefs = PreferenceManager.GetDefaultSharedPreferences(this);
                ISharedPreferencesEditor editor = prefs.Edit();
                editor.PutBoolean("Ck_Status", false);
                editor.PutString("UserName", null);
                editor.Commit();
                editor.Apply();
            }
