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

this code gives me the total number of week in that particular year. i.e. in this year there are 52 weeks. I don't want that. I want the number of weeks from the beginning of the year i.e. the week number till today is 9.. I want this thing not the total week.. – Abhishek Dhiman Mar 01 '13 at 09:58
I think you do something wrong. The following code returns 9 in my case. Calendar calendar = Calendar.getInstance(); int week = calendar.get(Calendar.WEEK_OF_YEAR); – azertiti Mar 01 '13 at 10:05

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

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

Plase provide the complete code... Not able to find sDateYearAAAA, sDateMonthMM, sDateDayDD, iStartWeek and not able to get the sDateCalendar.getWeekYear(); method.. – Abhishek Dhiman Mar 01 '13 at 09:56
do you want for current date only or for any string you pass? – Dinesh Prajapati Mar 01 '13 at 10:12

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);
