import java.text.SimpleDateFormat; SimpleDateFormat formatter = new SimpleDateFormat ("yyyy年MM月dd日 HH:mm:ss "); Date curDate = new Date(System.currentTimeMillis());//获取当前时间 String str = formatter.format(curDate);
可以获取当前的年月时分,也可以分开写:
SimpleDateFormat sDateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss"); String date = sDateFormat.format(new java.util.Date());
当然还有就是可以指定时区的时间(待):
df=DateFormat.getDateTimeInstance(DateFormat.FULL,DateFormat.FULL,Locale.CHINA); System.out.println(df.format(new Date()));
如何获取Android系统时间是24小时制还是12小时制
ContentResolver cv = this.getContentResolver(); String strTimeFormat = android.provider.Settings.System.getString(cv, android.provider.Settings.System.TIME_12_24); if(strTimeFormat.equals("24")) { Log.i("activity","24"); } Calendar c = Calendar.getInstance(); 取得系统日期:year = c.get(Calendar.YEAR) month = c.grt(Calendar.MONTH) day = c.get(Calendar.DAY_OF_MONTH) 取得系统时间:hour = c.get(Calendar.HOUR_OF_DAY); minute = c.get(Calendar.MINUTE)
利用Calendar获取
Calendar c = Calendar.getInstance(); 取得系统日期:year = c.get(Calendar.YEAR) month = c.grt(Calendar.MONTH) day = c.get(Calendar.DAY_OF_MONTH) 取得系统时间:hour = c.get(Calendar.HOUR_OF_DAY); minute = c.get(Calendar.MINUTE) Calendar c = Calendar.getInstance(); 取得系统日期:year = c.get(Calendar.YEAR) month = c.grt(Calendar.MONTH) day = c.get(Calendar.DAY_OF_MONTH) 取得系统时间:hour = c.get(Calendar.HOUR_OF_DAY); minute = c.get(Calendar.MINUTE)
利用Time获取
Time t=new Time(); // or Time t=new Time("GMT+8"); 加上Time Zone资料。 t.setToNow(); // 取得系统时间。 int year = t.year; int month = t.month; int date = t.monthDay; int hour = t.hour; // 0-23 int minute = t.minute; int second = t.second;
int month = (date.get(Calendar.MONTH))+1; int day = date.get(Calendar.DAY_OF_MONTH);
Calendar CD = Calendar.getInstance(); int YY = CD.get(Calendar.YEAR) ; int MM = CD.get(Calendar.MONTH)+1; int DD = CD.get(Calendar.DATE); int HH = CD.get(Calendar.HOUR); int NN = CD.get(Calendar.MINUTE); int SS = CD.get(Calendar.SECOND); int MI = CD.get(Calendar.MILLISECOND); Calendar cal = Calendar.getInstance(); //当前年 int year = cal.get(Calendar.YEAR); //当前月 int month = (cal.get(Calendar.MONTH))+1; //当前月的第几天:即当前日 int day_of_month = cal.get(Calendar.DAY_OF_MONTH); //当前时:HOUR_OF_DAY-24小时制;HOUR-12小时制 int hour = cal.get(Calendar.HOUR_OF_DAY); //当前分 int minute = cal.get(Calendar.MINUTE); //当前秒 int second = cal.get(Calendar.SECOND); //0-上午;1-下午 int ampm = cal.get(Calendar.AM_PM); //当前年的第几周 int week_of_year = cal.get(Calendar.WEEK_OF_YEAR); //当前月的第几周 int week_of_month = cal.get(Calendar.WEEK_OF_MONTH); //当前年的第几天 int day_of_year = cal.get(Calendar.DAY_OF_YEAR);
