                btn_signIn.setEnabled(false);
            }
        });
        //监听所选中的日期
//		calendar.setOnCalendarClickListener(new OnCalendarClickListener() {

//							R.drawable.calendar_date_focused);
//					date = dateFormat;//最后返回给全局 date
//				}
//			}
//		});

        //监听当前月份
        calendar.setOnCalendarDateChangedListener(new OnCalendarDateChangedListener() {
            public void onCalendarDateChanged(int year, int month) {
                popupwindow_calendar_month
