This is a calendar manipulation class based on
@DonManfred 's explorations which you can find at
https://www.b4x.com/android/forum/t...ntresolver-query-insert-update-delete.100229/.
It contains the following methods:
- AddCalendar: Adds a new Calendar and returns its id, or -1 if no Calendar was added
- GetAllVisibleCalendars: Returns a list of type CalendarInfo containing all visible Calendars
- GetCalendarByID: Returns a variable of type CalendarInfo containing the selected Calendar's data, or Null if the ID doesn't exist
- GetCalendarByName: Returns a list of type CalendarInfo containing all Calendars with the specified name
- AddEvent: Adds a new Event to a Calendar and returns the new Event's id, or -1 if no Event was added
- GetAllVisibleEventsForCalendar: Returns a list of type EventInfo containing all visible Events for the specified Calendar id
- GetAllVisibleEventsInstancesForCalendar: Returns a list of type EventInfo containing all visible Events' Instances for the specified Calendar id
- GetSelectedEventsForCalendar: ' Returns a list of type EventInfo containing selected Events for the specified Calendar id
- GetSelectedEventsInstancesForCalendar: ' Returns a list of type EventInfo containing selected Events' Instances for the specified Calendar id
- GetEventByID: Returns a variable of type EventInfo containing the selected Event's data, or Null if the ID doesn't exist
- UpdateEvent: Attempts to update an Event and returns the number of Events that were updated
- DeleteEvent: Attempts to delete an Event and returns the number of Events that were deleted
- AddAttendeeToEvent: Adds an Attendee to an Event and returns the id of the added Attendee, or -1 if no Attendee was added
- GetEventAttendees: Returns a list of type AttendeeInfo containing all Attendees for the selected Event id
- AddReminderToEvent: Adds a Reminder to an Event and returns the id of the added Reminder, or -1 if no Reminder was added
- GetEventReminders: Returns a list of type ReminderInfo containing all Reminders for the selected Event id
Important:
- CalendarInfo, EventInfo, AttendeeInfo, and ReminderInfo are Types that are defined in the class
- Events vs. Instances: Instances are individual instances of recurring Events
- The Manifest has been edited as well, and RuntimePermissions must be requested - see @DonManfred 's post
- General Google information about the Calendar provider that can be useful when 'strange' things seem to happen (the Calendar is a complex beast):
https://developer.android.com/guide/topics/providers/calendar-provider
Non-core library dependencies:
- GoogleCalendarClient: get V0.2 from
@DonManfred's post
- ContentResolver
- RuntimePermissions
- SQL
An example project is attached, feel free to modify as desired; if you'd add/improve functionality, please post it here as well.
Enjoy!
EDIT 2022-04-19: adding an all-day event caused it to wind up for 'yesterday' instead of 'today'. The attached project was updated with the correct way to handle this, and comments were added.
