Acquisition of system date and time in Android

1. Get the current time:

Import     Java.text.SimpleDateFormat;              SimpleDateFormat    Formatter    =   new    simpledateformat    ("YYYY year mm month DD Day    hh:mm: SS     ");       Date    curdate    =   new    date (System.currenttimemillis ());   Gets the current       time of the String    str    =    Formatter.format (curdate);  

2. you can get the current year or month, or you can write separately:

SimpleDateFormat    Sdateformat    =   new    SimpleDateFormat ("Yyyy-mm-dd    hh:mm:ss");       String    date    =    Sdateformat.format (new    java.util.Date ());    

3. If you want to get the current month or year, you can write this (just get the time or the second type):

SimpleDateFormat sdf=New SimpleDateFormat ("yyyy-mm");    String Date=sdf.format (new java.util.Date ());  

4. and of course, time zone can be specified (pending):

df=dateformat.getdatetimeinstance (Dateformat.full,dateformat.full,locale.china);  System.out.println (Df.format(new Date ()));  

5. How to get the Android system time is 24 hour or 12 hour system

 This . Getcontentresolver ();          = android.provider.Settings.System.getString (CV,                                            android.provider.Settings.System.TIME_12_24);                  if (Strtimeformat.equals (")        ") {                log.i ("activity", "+");         }  

Calendar C = 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)  

6. Use the calendar to get

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)

7. Use Time to get

 time T=//   T.settonow ();  get system time.   int  year = T.year;   int  month = T.month;   int  date = T.monthday;  //  0-23   int  minute = T.minute;
