You can create a Calendar object for that date and get the week with calendar.get(Calendar. WEEK_OF_YEAR). The API is described here: http://developer.android.com/reference/java/util/Calendar.html#WEEK_OF_YEAR

回答2:

    Calendar calender = Calendar.getInstance();
    Log.d("Current Week:" + calender.get(Calendar.WEEK_OF_YEAR));

回答3:

Calendar sDateCalendar = new GregorianCalendar(2013,03,01);
Calendar.getInstance().get(Calendar.WEEK_OF_YEAR);

回答4:

01/03/2013 is taken in as 113 , 2 ,1

            Date d = new Date(113, 2, 1);

            Calendar c = Calendar.getInstance();

            c.setTime(d);

            int weekOfYear = c.get(Calendar.WEEK_OF_YEAR);
