Using c.get(Calendar.WEEK_OF_YEAR); I can get the week number but how to get the start & end date? I've found an answer here pointing to MonthDisplayHelper , but how to use it?

Thanks!

Answer 1

Used this sintax and it worked

    Calendar c1 = Calendar.getInstance();

    //first day of week
    c1.set(Calendar.DAY_OF_WEEK, 1);

    int year1 = c1.get(Calendar.YEAR);
    int month1 = c1.get(Calendar.MONTH)+1;
    int day1 = c1.get(Calendar.DAY_OF_MONTH);

    //last day of week
    c1.set(Calendar.DAY_OF_WEEK, 7);

    int year7 = c1.get(Calendar.YEAR);
    int month7 = c1.get(Calendar.MONTH)+1;
    int day7 = c1.get(Calendar.DAY_OF_MONTH);

Here is the good example code, which gives you the current week of the year as well as week starting and ending date, Just what you need to do is set the starting day of the week in code, In my case I set it as SUNDAY,

// get Current Week of the year
    calendar=Calendar.getInstance();
    Log.v("Current Week", String.valueOf(calendar.get(Calendar.WEEK_OF_YEAR)));
    int current_week=calendar.get(Calendar.WEEK_OF_YEAR);
    int week_start_day=calendar.getFirstDayOfWeek(); // this will get the starting day os week in integer format i-e 1 if monday
    Toast.makeText(getContext(),"Current Week is"+current_week +"Start Day is"+week_start_day,Toast.LENGTH_SHORT).show();


    // get the starting and ending date
    // Set the calendar to sunday of the current week
    calendar.set(Calendar.DAY_OF_WEEK, Calendar.SUNDAY);
    System.out.println("Current week = " + Calendar.DAY_OF_WEEK);

    // Print dates of the current week starting on Sunday
    DateFormat df = new SimpleDateFormat("yyyy-MM-dd", Locale.getDefault());
    String startDate = "", endDate = "";

    startDate = df.format(calendar.getTime());
    calendar.add(Calendar.DATE, 6);
    endDate = df.format(calendar.getTime());

    System.out.println("Start Date = " + startDate);
    System.out.println("End Date = " + endDate);
