I am still trying to create a monthview with calendarView.
My problem is that I have no idea how I could switch the month of calendarView. I want to click a button and then the view shall display the next or last month. The view is alredy grounded, so you cant scroll through.
CalendarView cal = (CalendarView) findViewById(R.id.calendarMonthView);
cal.setEnabled(false);
My idea is to do it with following Code:
long **dateOfLastMonth** = currentMonth - month; // pseudo code
CalendarView lastMonth = (CalendarView) findViewById(R.id.calendarMonthView);
lastMonth.setDate(**dateOfLastMonth**);
But I have no idea what value dateOfLastMonth should have.
Is that the right way? What value should dateOfLastMoth (no idea because it must be a long) have? Is there another way?
Try this:
Calendar cal = Calendar.getInstance(); // Calendar object, with time set to now
cal.add(Calendar.MONTH, -1); // subtract a month
long dateOfLastMonth = cal.getTimeInMillis(); // get the milliseconds since 01/01/1970
If you want the 1st of the month do this
cal.set(Calendar.DAY_OF_MONTH, 1);
I suggest to do that before subtracting a month, because I don't know what happens if today is the 31st of the month and the previous month doesn't have a 31st.
Edit: It wouldn't be a problem if it's the 31st, I just tried it and the Calendar just sets to the 30th of the previous month
