Date nowDate = nowTime.getTime();
public static String getTime(long time) {
Date da = new Date(time);
String dateFormat = "yyyy-MM-dd HH:mm:ss";
SimpleDateFormat sdf = new SimpleDateFormat(dateFormat);

calendar.get(Calendar.YEAR) - 1900 +"年"+
calendar.get(Calendar.MONTH)+"月"+calendar.get(Calendar.DAY_OF_WEEK)
+"日"+ calendar.get(Calendar.HOUR_OF_DAY) +":"+calendar.get(Calendar.MINUTE)
+":"+calendar.get(Calendar.SECOND)) 改成：
SimpleDateFormat sf=new SimpleDateFormat("yyyy年-MM月-dd日 hh時:mm分:ss秒");
String s=sf.format(new Date());
