Acquisition of system date and time in Android

from:http://blog.csdn.net/feifei454498130/article/details/6540133ImportJava.text.SimpleDateFormat; SimpleDateFormat Formatter=NewSimpleDateFormat ("yyyy mm month DD Day HH:MM:SS"); Date curdate=NewDate (System.currenttimemillis ());//Get current TimeString str =Formatter.format (curdate); You can get the current year or month, or you can write separately: [Java] View Plaincopyprint?SimpleDateFormat Sdateformat=NewSimpleDateFormat ("Yyyy-mm-dd hh:mm:ss"); String Date= Sdateformat.format (Newjava.util.Date ()); If you want to get the current month and year, you can write this (just get the time or the second): Java code [Java] View Plaincopyprint?SimpleDateFormat SDF=NewSimpleDateFormat ("yyyy-mm"); String Date=sdf.format (Newjava.util.Date ()); And, of course, the time zone can be specified (pending): [Java] View Plaincopyprint?DF=dateformat.getdatetimeinstance (Dateformat.full,dateformat.full,locale.china); System.out.println (Df.format (NewDate ())); 

how to get the Android system time is 24 hour or 12 hour system

    [Java] view Plaincopyprint?  this. Getcontentresolver ();          = android.provider.Settings.System.getString (CV,                                            android.provider.Settings.System.TIME_12_24);                  if (Strtimeformat.equals (")        ") {                log.i ("activity", "+");         }   

[Java] view Plaincopyprint?  = calendar.getinstance ();   = C.get (calendar.year)                 = c.grt (calendar.month)                 = c.get (calendar.day_of_month)  = C.get (calendar.hour_of_day);                     = C.get (calendar.minute)    

Use Calendar to get

[Java] View plaincopyprint?Calendar C=calendar.getinstance (); Get system date: year=C.get (calendar.year) Month=c.grt (calendar.month) Day=C.get (calendar.day_of_month) Acquisition system time: Hour=C.get (Calendar.hour_of_day); Minute=c.get (Calendar.minute) Calendar c=calendar.getinstance (); Get system date: year=C.get (calendar.year) Month=c.grt (calendar.month) Day=C.get (calendar.day_of_month) Acquisition system time: Hour=C.get (Calendar.hour_of_day); Minute=c.get (Calendar.minute)

Use Time to get

 [Java] View plaincopyprint?  time t  =new  time (); //   T.settonow (); //   get system time.   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;
