Question

I\'m trying to create a weekly calendar that looks like this: http://dhtmlx.com/docs/products/dhtmlxScheduler/sample_basic.html

How can I calculate every week date?

Answer 1

    Calendar startCal = Calendar.getInstance();
    startCal.setTimeInMillis(startDate);
    Calendar endCal = Calendar.getInstance();
    endCal.setTimeInMillis(endDate);
    SimpleDateFormat sdf = new SimpleDateFormat("dd-MMMM-yyyy");
    while (startCal.before(endCal)) {
        int weekNumber = startCal.get(Calendar.WEEK_OF_YEAR);
        Calendar cal = Calendar.getInstance();
        cal.set(Calendar.DAY_OF_WEEK, Calendar.SUNDAY);
        cal.set(Calendar.WEEK_OF_YEAR, weekNumber);
        Date sunday = cal.getTime();
        Log.d("sunday", "" + sdf.format(sunday));
        cal.set(Calendar.DAY_OF_WEEK, Calendar.SATURDAY);
        cal.set(Calendar.WEEK_OF_YEAR, weekNumber);
        Date saturday = cal.getTime();
        Log.d("saturday", "" + sdf.format(saturday));
        weekNumber = weekNumber + 1;
        startCal.set(Calendar.WEEK_OF_YEAR, weekNumber);

    }
