    import java.util.calendar;      ...      calendar test = calendar.getinstance();      test.setfirstdayofweek(calendar.monday);      log.e("weeek test:", ""+ test.get(calendar.week_of_year));      test.add(calendar.week_of_year, 1);      log.e("weeek test:", ""+ test.get(calendar.week_of_year));
