How to get a day from a specified date in Android

Question

Suppose my date is 02-01-2013

and it is stored in a variable, for example:

String strDate = "02-01-2013"; 

then how should I get the day of this date (i.e. TUESDAY)?

Answer 1

Use Calendar class from java api.

 Calendar calendar = new GregorianCalendar(2008, 01, 01); // Note that Month value is 0-based. eg, 0 for January. int reslut = calendar.get(Calendar.DAY_OF_WEEK); switch (result) { case Calendar.MONDAY: System.out.println("It Monday !"); break; } 

You can also use SimpleDateFormater and Date for parsing dates.

 Date date = new Date(); SimpleDateFormat date_format = new SimpleDateFormat("yyyy-MM-dd"); try { date = date_format.parse("2008-01-01"); } catch (ParseException e) { e.printStackTrace(); } calendar.setTime(date); 

Answer 2

First split the line

 String[] out = strDate.split("-"); s1 = Integer.parseInt(out[0]); s2 = Integer.parseInt(out[1]) - 1; yr = out[2]; char a, b, c, d; a = yr.charAt(0); b = yr.charAt(1); c = yr.charAt(2); d = yr.charAt(3); s3 = Character.getNumericValue(a)*1000 + Character.getNumericValue(b)*100 + Character.getNumericValue(c)*10 + Character.getNumericValue(d); 

then create an instance of the calendar that day

 Calendar cal = Calendar.getInstance(); cal.set(s3, s2, s1); 

then get the day

 cal.get(Calendar.DAY_OF_WEEK); 

Answer 3

Use this format for date, day, and time.

Date dNow = new date (); SimpleDateFormat ft = new SimpleDateFormat ("E yyyy.MM.dd" in "hh: mm: ss a zzz");

and exit the object here using the format method. ft.format (dNow)

Answer 4

I think based on Android documentation it is suggested to use Calendar,

You need to be careful because the first day is Sunday and the first month of January. Also check that you can get DAY_OF_WEEK, DAY_OF_MONTH, etc.
