Hi,

I have a webservice that need to get a list of dates. I need to parse those dates and show them in the selected state in the calendarview. But I didn't find any method that sets a day in the selected state without clicking on the day.

So far I've tried the following,

public class ShiftSelectionManager extends BaseCriteriaSelectionManager {
    
    private Context context;
    private Set<Day> days = new HashSet<>();
    CustomDelegate delegate;
    static Day selectedDay;

    public ShiftSelectionManager(Context context, CustomDelegate delegate,  OnDaySelectedListener onDaySelectedListener) {
        this.context = context;
        this.onDaySelectedListener = onDaySelectedListener;
        this.delegate = delegate;
    }

    @Override
    public void toggleDay(@NonNull Day day) {
        this.selectedDay =day;
        Calendar cal = day.getCalendar();
        Log.v("CAL", cal.getTime()+"");
        if (cal.getTime().equals(new Date()) || cal.getTime().before(new Date())) {
            Utils.customAlert(context, "Oops!", "You cannot choose a shift that is today or in the past shifts.", null);
        }else{
            if (days.contains(day)) {
                ((ScheduleCalendarActivity)context).lnrCalendarSheet.setVisibility(View.VISIBLE);
            } else {
                ((ScheduleCalendarActivity)context).lnrCalendarSheet.setVisibility(View.GONE);

                Intent intent = new Intent(context, SelectShiftActivity.class);
                SelectShiftActivity.delegate = delegate;
                intent.putExtra("Calendar", cal);
                context.startActivity(intent);
            }

        }
    }

    @Override
    public boolean isDaySelected(@NonNull Day day) {
        return days.contains(day);
    }

    @Override
    public void clearSelections() {
        days.clear();
    }

    public void removeDay(Day day) {
        days.remove(day);
        //((ScheduleCalendarActivity)context).calendar.update();
        //onDaySelectedListener.onDaySelected();
    }
   //Add single day
    public void addDay(){
        days.add(selectedDay);
        isDaySelected(selectedDay);
    }

    public void addAllDays(Set<Day> days){
            this.days = days;   
    }
}

And on my activity I did the following,

//Setup the Calendar View

void setupCalendar() {
        calendar.setCalendarOrientation(OrientationHelper.HORIZONTAL);
        calendar.setSelectionType(SelectionType.MULTIPLE);
        calendar.setSelectedDayBackgroundColor(Color.parseColor(Theme.PRIMARYCOLOR));


        calendar.setSelectionManager(new ShiftSelectionManager(this, myDelegate, new OnDaySelectedListener() {
            @Override
            public void onDaySelected() {

            }
        }));
    }

//Get Date From API
void setupSchedule() {
        AppPrefs prefs = new AppPrefs(this);
        Map<String, String> map= new HashMap<>();
        map.put("Authorization","Bearer "+prefs.getStringFromKey(Sharedkey.accessTokenKey));

        ApiRequests.HttpGetShiftList(this,map,"/v11/shift/get/myshift", new IHttpListener() {
            @Override
            public void OnSuccess(Object obj) {
                try {
                    JSONObject feedObj = new JSONObject((String) obj);
                    JSONArray feedObjJSONArray = feedObj.getJSONArray("shift");
                    for (int i = 0; i < feedObjJSONArray.length(); i++) {
                        JSONObject singleFeedObj = feedObjJSONArray.getJSONObject(i);
                        Schedule schedule = new Gson().fromJson(singleFeedObj.toString(), Schedule.class);
                        myShiftList.add(schedule);
                        daySet.add(new Day(Utils.toFormattedDate(schedule.getDateOfShift())));
                    }
if (calendar.getSelectionManager() instanceof ShiftSelectionManager) {
            ((ShiftSelectionManager) calendar.getSelectionManager()).addAllDays(daySet);
        }
        calendar.update();

                } catch (Exception e) {

                }
            }

            @Override
            public void OnError(String error) {

            }
        });
    }
 

Should the user be allowed to select a range date, when within it, there is a disabled (or more than one) disabled day ?

For instance:

October 4th is disabled

I'd gladly drop a PR fixing it (if it's a bug)

Add posibility mark days how to special days, for fix holidays in calendar, chistmas...

My suggestion...

Simple method: setHolidayDays... holydayDayTextColor disabledHolidayDayTextColor (priority color, if don't set, get disabledDayTextColor)

Other case In the future you may want to support seasons, so you can see if you are selecting a high season day, low ...

seasonDays , seasonColor , seasonColorDisable (optional)

//High Season
Set<Long> seasonHighDaysSet = new HashSet<>();
calendarView.setSeasonDays(seasonHighDaysSet,Color.Green);
calendarView.setSeasonDays(seasonHighDaysSet,Color.Green,Color.LightGreen);

//Low season
Set<Long> seasonLowDaysSet = new HashSet<>();
calendarView.setSeasonDays(seasonLowDaysSet ,Color.Blue);
calendarView.setSeasonDays(seasonLowDaysSet ,Color.Blue,Color.LightBllue);

//Winter season
Set<Long> seasonWinterDaysSet = new HashSet<>();
calendarView.setSeasonDays(seasonWinterDaysSet ,Color.Orange);
calendarView.setSeasonDays(seasonWinterDaysSet ,Color.Blue,Color.LightOrange);

...

seasonColorDisable (priority color, if don't set, get disabledDayTextColor)

Did anyone come across this problem?

Like bolding, the text of selected date is also bolding a random date without the circle. I think the recycler view is having a spread over issue. Can someone help me with this

for example, today is November 28, 2017, will be the date of the arrow marked today, I just click on a date in radio mode, then, on November 3, 2017 will also be marked as the current date, mean there will be two current date, however, the problem is not inevitable

Hi,

Thanks for putting together this very useful library.

I encountered this error when rapidly scrolling through months with the calendar in horizontal configuration and the selection type set to multiple. To be honest this was more of a stress test, but i ended up with this exception...

java.util.ConcurrentModificationException · Raw ArrayList.java:573java.util.ArrayList$ArrayListIterator.next CalendarView.java:573com.applikeysolutions.cosmocalendar.view.CalendarView.getSelectedDays CalendarView.java:628com.applikeysolutions.cosmocalendar.view.CalendarView.onDaySelected MultipleSelectionManager.java:38com.applikeysolutions.cosmocalendar.selection.MultipleSelectionManager.toggleDay DayDelegate.java:38com.applikeysolutions.cosmocalendar.view.delegate.DayDelegate$1.onClick View.java:5226android.view.View.performClick View.java:21266android.view.View$PerformClick.run Handler.java:739android.os.Handler.handleCallback Handler.java:95android.os.Handler.dispatchMessage Looper.java:168android.os.Looper.loop ActivityThread.java:5845android.app.ActivityThread.main Method.java:-2java.lang.reflect.Method.invoke ZygoteInit.java:797com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run ZygoteInit.java:687com.android.internal.os.ZygoteInit.main

There is also noticeable lag when scrolling quickly through the months - i wondered if it's possible to set a limit on how far in the future/past the user is able to scroll? For example, can I limit the calendar to scroll no further than 1 year in the future?

Many thanks in advance

Hello. When I add to my dependencies, I get an error ERROR: Unable to resolve dependency for ':app@gebDebug/compileClasspath': Could not resolve com.github.applikeysolutions:cosmocalendar:1.0.4.

When I choose range day, end range always return one day after start range

this is my code :

CalendarDialog cal = new CalendarDialog(getActivity()); cal.setOnDaysSelectionListener(new OnDaysSelectionListener() { @Override public void onDaysSelected(List selectedDays) { if (selectedDays.size()>0) { checkin_date = selectedDays.get(0).getCalendar().getTime(); checkin_string_date = formatMonth.format(checkin_date)+"/"+formatDay.format(checkin_date)+"/"+formatYear.format(checkin_date); tanggalin.setText(ExtradateFormatForMonth.format(checkin_date));

                if (selectedDays.size()>1)
                {
                    checkout_date = selectedDays.get(1).getCalendar().getTime();
                    checkout_string_date = formatMonth.format(checkout_date)+"/"+formatDay.format(checkout_date)+"/"+formatYear.format(checkout_date);
                    tanggalout.setText(ExtradateFormatForMonth.format(checkout_date));
                }

            }
        }
    });

cal.show(); cal.setSelectionType(SelectionType.RANGE);

### SOLUTION TO ADD EVENTS

I was searching for a way to add marker on particular dates, but didn't find any. However as you can see in above image, I have managed to add marker to Calendar dates. I have used addConnectedDays() provided by Cosmo Calendar. Markers can be added on TOP & BOTTOM of date. Sharing code I used:

                    Set<Long> days = new TreeSet<>();
                    e.g. 
                    String date1 = "05-18-2021";
                    String date2 = "05-09-2021";
                    //........

                    SimpleDateFormat sdf1 = new SimpleDateFormat("MM-dd-yyyy");
                    try {
                        Date mDate1 = sdf1.parse(date1);
                        long timeInMilliseconds1 = mDate1.getTime();

                        
                        Date mDate2 = sdf1.parse(date2);
                        long timeInMilliseconds2 = mDate2.getTime();

                        days.add(timeInMilliseconds1);
                        days.add(timeInMilliseconds2);
                        // can add more days to set

                    } catch (Exception e) {
                        Log.e("DateException", e.getMessage());
                    }
          
                int textColor = Color.parseColor("#0063B0");
                int selectedTextColor = Color.parseColor("#FFFFFF");
                int disabledTextColor = Color.parseColor("#ff8000");
                ConnectedDays connectedDays = new ConnectedDays(days, textColor, selectedTextColor, disabledTextColor);

                //Add Connect days to calendar
                calendarView.addConnectedDays(connectedDays);

                calendarView.setConnectedDayIconRes(R.drawable.ic_baseline_star_24);   // Drawable
                calendarView.setConnectedDayIconPosition(ConnectedDayIconPosition.TOP);// TOP & BOTTOM
                calendarView.update();

I want to mark few dates as selected and rest as disabled. How can i do this.

Example:-

I want to mark 19-02-2021 and 20-02-2021 as selected and rest as disabled.
