Event in calendar android

Android Essentials: Adding Events to the User’s Calendar

The latest version of the Android SDK, code-named Ice Cream Sandwich, reached developers this week. For the first time, the SDK provides access to the Calendar application in a legitimate fashion. One of the most common tasks that developers often want to be able to do is create new events in the user’s calendar, so today we’ll show you how.

The Calendar is a common application that users rely upon on their Android devices. Applications can access the Calendar using the new APIs available in Android 4.0. Adding new events to the Calendar is simple and requires no special application permissions.

Note: The user is responsible for configuring the Calendar application with the appropriate Calendar accounts (e.g. Microsoft Exchange).

Step 0: Getting Started

This tutorial assumes you have a project that supports Android 4.0 (API Level 14 compatible) and that you are compiling with the latest tools. It also assumes that you’ve properly configured the Calendar application on the Android emulator (or a suitable device, when one becomes available in the coming weeks).

Step 1: Create the Calendar Intent

In order to prompt the user to create a calendar event in their existing calendar, you’ll need to create the appropriate intent. This intent will launch the Calendar application with a screen that allows them to create a new event. The user must confirm this event and can add or change any of the event data associated with the event.

The intent to create a calendar event is shown below:

This code simply launches the intent. It does not set any of the calendar data associated with the event.

Step 2: Seeding Calendar Details

You can seed the information associated with a calendar event by supplying a number of intent extras. Extras can be used to describe event details, the date and time of the event, as well as calendar event settings like whether the event can be seen by others and whether it is busy or available time. The typical calendar event settings are all available as Extras. For example, the following intent call supplies some title and description information about an event:

Here we set the title, location, and description access for the event using the appropriate intent Extras. These fields will be set in a form that displays for the user to confirm the event in their calendar.

Step 3: Seeding Calendar Dates and Times

Calendar events are associated with specific dates and times. Some events have a specific time window and others are “all day” events. You can specify the date and time of an event using extras as well.

Here we set the event to be an all day event on a specific date. You can also set much more fine-grained events by simply using the two extras for the beginning and ending time.

Step 4: Event Configuration Details

There are several other intent extras you can seed as well. These include whether or not others can see the event (access level) and whether or not the time should be shown as busy or available (availability)

You could set these extras as follows:

Here we include an extra setting to set the access of this event in the calendar to private. We set the availability during the event’s time period to busy (no other events can overlap).

Step 5: Configuring Recurring Events

There are one-time events, like our pig roast, and then there are recurring events, like by-weekly meetings. You can seed the recurrence rule using an intent extra, like this:

The RRULE intent extra takes a standard iCalendar recurrence rule format (see RFC 5544 for details). For example, the one above creates a recurrence rule for an event that occurs every Tuesday and Thursday for 5 weeks.

Conclusion

The Calendar application has been available on the Android platform for a long time, but there have been no documented APIs for accessing it: until now. Android 4.0 (API Level 14) includes a full Calendar content provider which can be used to access the user’s calendar information, provided the application has the appropriate permissions. However, one of the simplest and most common tasks, adding a new event to a user’s calendar, requires no special permissions and is very easy to implement.

Recent Changes

Major Change in 1.5.0

We recently updated to the latest gradle and decided to move over our libraries to the hosting service Jitpack. Please refer to the installation section for more details.

Major Change in 1.4.0

• Breaking Change: setFirstDayOfWeek , setMin/MaxDate , and setCalendarDisplayMode are moved to a State object. This was necessary because it was unclear that these were not simple setters—individually, they were side effecting and triggered full adapter/date range recalculations. Typical usage of the view involves setting all these invariants up front during onCreate and it was unknown to the user that setting all 4 of these would create a lot of waste. Not to mention certain things were side effecting—some would reset the current day or selected date. As a result, the same 4 methods called in a different order could result in a different state, which is bad.
• For most cases you will simply need to replace setting those invariants with:
• mcv.state().edit() .setFirstDayOfWeek(Calendar.WEDNESDAY) .setMinimumDate(CalendarDay.from(2016, 4, 3)) .setMaximumDate(CalendarDay.from(2016, 5, 12)) .setCalendarDisplayMode(CalendarMode.WEEKS) .commit();
• mcv.state().edit() will retain previously set values; mcv.newState() will create a new state using default values. Calling commit will trigger the rebuild of adapters and date ranges. It is recommended these state changes occur as the first modification to MCV (before configuring anything else like current date or selected date); we make no guarantee those modifications will be retained when the state is modified.
• See CUSTOMIZATION_BUILDER for usage details.
• New: setSelectionMode(SELECTION_MODE_RANGE) was added to allow 2 dates to be selected and have the entire range of dates selected. Much thanks to papageorgiouk for his work on this feature.

After that go in the Activity/Fragment where you added the CustomizableCalendar View; here you should specify the first month and the last month, to do this, create a Calendar (located in com.molo17.customizablecalendar.library.model ) object.

An example of CustomizableCalendar init is the following:

How to customize

If you want to customize the components you should create a separeted layout and add the reference to the customizable_calendar View with the tag app:layout=»@layout/your_layout»

An example of a custom layout is the following:

NOTE that ids must not be different from the ones above, so:

• @android:id/primary for HeaderView;
• @android:id/text1 for WeekDaysView;
• @android:id/text2 for SubView;
• @android:id/content for CalendarRecyclerView;

HeaderView

First (red) rectangle of the screenshot above.
It’s a RelativeLayout , you should create your own layout.

WeekDaysView

Third (light blue) rectangle of the screenshot above.
It’s a RecyclerView , the ViewHolder item is already implemented.
You can create your own ViewHolder layout using a RelativeLayout with a TextView that has @android:id/summary as id.

SubView

Second (green) rectangle of the screenshot above.
It’s a RelativeLayout , implemented by default with the name of the month centered.
If you want to create your own layout make sure to have a TextView with id @android:id/summary .

CalendarRecyclerView

Fourth (blue) rectangle of the screenshot above.
It’s a RelativeLayout , implemented by default with a LinearLayout (with a GridLayout inside) for the month and a RelativeLayout for the day.
If you want to create your own month layout you can specify app:month_layout=»@layout/your_layout» for the month and app:cell_layout=»@layout/your_layout» for the day.
Make sure to use @android:id/widget_frame as id for the GridView and @android:id/background , @android:id/startSelectingText , @android:id/stopSelectingText , @android:id/title respectively for single selection background, first day selection background (in multiple selection mode), last day selection background (in multiple selection mode) and the TextView where the day is displayed.

All code customization can be applied using the ViewInteractor .

Here are listed all of the methods with a small description:
