2. Import Java.text.SimpleDateFormat;
6. SimpleDateFormat formatter = new SimpleDateFormat ("yyyy mm month DD Day HH:mm:ss");
8. Date curdate = new Date (System.currenttimemillis ()); Get current time
10. String str = Formatter.format (curdate);

 

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

  [Java]View Plaincopyprint?

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

 

If you want to get the current month and year, you can write this (just get the same time or seconds):

Java Code

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

Of course, there are times when you can specify a time zone (wait):

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

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

2. Contentresolver CV = this.getcontentresolver ();
4. String Strtimeformat = android.provider.Settings.System.getString (CV,
6. ANDROID.PROVIDER.SETTINGS.SYSTEM.TIME_12_24);
10. if (strtimeformat.equals (")" )
12. {
14. LOG.I ("activity","24");
16. }

1. Calendar C = calendar.getinstance ();
2. Get system date: Year = C.get (calendar.year)
3. month = C.GRT (calendar.month)
4. Day = C.get (calendar.day_of_month)
5. Acquisition system time: Hour = C.get (Calendar.hour_of_day);
6. minute = C.get (Calendar.minute)

Use Calendar to get

[Java]View Plaincopyprint?

2. Calendar C = calendar.getinstance ();
4. Get system date: Year = C.get (calendar.year)
6. month = C.GRT (calendar.month)
8. Day = C.get (calendar.day_of_month)
10. Acquisition system time: Hour = C.get (Calendar.hour_of_day);
12. minute = C.get (Calendar.minute)
14. Calendar C = calendar.getinstance ();
16. Get system date: Year = C.get (calendar.year)
18. month = C.GRT (calendar.month)
20. Day = C.get (calendar.day_of_month)
22. Acquisition system time: Hour = C.get (Calendar.hour_of_day);
24. minute = C.get (Calendar.minute)

Use Time to get

[Java]View Plaincopyprint?

1. Time t=new Time ();  //or Time T=new time ("Gmt+8"), plus time zone information.
2. T.settonow ();  //Get system time.
3. int year = T.year;
4. int month = T.month;
5. int date = T.monthday;
6. int hour = T.hour; //0-23
7. int minute = T.minute;
8. int second = T.second;

The only disadvantage is that the removal time is only 24 hours mode.
