How to get day of the week from CalendarView

Question

I'm having a CalendarView in my layouts and I've added the Date change listener to it:

calendarView = (CalendarView)findViewById(R.id.calendarView);

calendarView.setOnDateChangeListener(new CalendarView.OnDateChangeListener() {
    @Override
    public void onSelectedDayChange(CalendarView view, int year, int month, int dayOfMonth) {

        Log.i("View.getDate", view.getDate() + "");
    }
});

I can access the selected date's year, month and day-of-the-month. But how do I get the day of the week? I want that information for any date that I select in the CalendarView.

I put view.getDate() in the logs, only to know it's giving me the same output (value for today's date) on every date that I select. What am I missing?

UPDATE:

calendar.set(year, month, dayOfMonth);

correctly sets the calendar value correctly, while the following:

calendar.setTimeInMillis(view.getDate());

doesn't. Don't know the reason.

For example:

calendarView.setOnDateChangeListener(new CalendarView.OnDateChangeListener() {
    @Override
    public void onSelectedDayChange(CalendarView view, int year, int month, int dayOfMonth) {

        Calendar calendar = Calendar.getInstance();
        calendar.set(year, month, dayOfMonth);
        int dayOfWeek = calendar.get(Calendar.DAY_OF_WEEK);
     }
});

That's where the problem is. `view.getDate` is returning me the same result - no matter what date I select. – Akeshwar Jha Mar 07 '16 at 11:35
Thankyou. I don't know why `view.getDate` is returning the same value. Any thoughts? `calendar.set(year, month, dayOfMonth)` sets the calendar value properly. – Akeshwar Jha Mar 07 '16 at 11:53

Use the Android Calendar class.

Calendar selected = Calendar.getInstance();
selected.setTimeInMillis(view.getDate());
int dayOfWeek = selected.get(Calendar.DAY_OF_WEEK);

switch (dayOfWeek ) {
    case Calendar.SUNDAY:
        // ...

    case Calendar.MONDAY:
        // etc ...
}

this should not be difficult, for example does this answer your question? Android: how to get the current day of the week (Monday, etc...) in the user's language?

Try with this use the Calendar and set it through the time you get from the calendar view:

    Calendar selected = Calendar.getInstance();
    selected.setTimeInMillis(calendarView .getDate());
    int dayOfWeek = selected.get(Calendar.DAY_OF_WEEK);

Hi, thanks for the response. But I'm getting the same value for `view.getDate` no matter what date I select. – Akeshwar Jha Mar 07 '16 at 11:37

hmm if you set year, month and day to Calendar which values can get from onSelectedDayChange selected.set(year,month,day); and remove selected.setTimeInMillis(calendarView .getDate()); did this help ? – Kristiyan Varbanov Mar 07 '16 at 11:45
Yup, setting year, month and day does the thing, but why not `getDate`? Any idea? – Akeshwar Jha Mar 07 '16 at 11:48

 public static int dayOfWeek(String date) {
    try {
        int day = 0;
        SimpleDateFormat simpleDateformat = new SimpleDateFormat("yyyy-MM-dd");
        Date now = simpleDateformat.parse(date);
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(now);
        day = calendar.get(Calendar.DAY_OF_WEEK);
        return day;
    } catch (Exception e) {
        return 0;
    }
}

Then you can use Calendar.MONDAY, Calendar.TUESDAY etc.

Hope this is helpful.

use Calender class from java api.

calendarView = (CalendarView)findViewById(R.id.calendarView);

calendarView.setOnDateChangeListener(new     CalendarView.OnDateChangeListener() {
    @Override
    public void onSelectedDayChange(CalendarView view, int year, int month, int dayOfMonth) {

        Log.i("View.getDate", view.getDate() + "");
        /*
             for month you can use following. like
              0 for jan
              1 for feb

        */
         int newMonth;
         if(month > 9){
           newMonth= month-1;
         }
        else{
            switch(month){
              case (1|01):{
                 newMonth = 0;
              }
              break;
              case (2|02):{
                 newMonth = 1;
              }
              break;
             ....
             }
         }
            Calendar calendar = new      GregorianCalendar(year, newMonth
, dayOfMonth);
            int result = calendar.get(Calendar.DAY_OF_WEEK);
        switch (result) {
        case Calendar.MONDAY:
            System.out.println("It's Monday !");
            break;
    }
    }
});

I hope, This will help you..

Too late but well, I had the same problem. I solved it with this.

    public static int dayOfWeek(int day, int month, int year) {

    Calendar c = Calendar.getInstance();

    c.set(year,month,day);

    return c.get(Calendar.DAY_OF_WEEK);
}

This method return the day of the week in an int. If the day is Sunday it return 1 and if it's Wednesday return 4.
