using the Calendar Events. This is specially for 2.2 version
Follow the below steps to do the insertion and deletion operations in Calendar events.
Step 1:
Firstof all we need to get the Calendar Name and Id,
As
there is a chance of having many calendar configurations in a mobile,
we must find out available calendar's. Using that calendars name and id
only we can proceed further
Cursor cursor=getContentResolver().query(Uri.parse("content://com.android.calendar/calendars"), new String[]{"calendar_id", "displayname"}, null, null, null);
cursor.moveToFirst();
// Get calendars name
String calendarNames[] = new String[cursor.getCount()];
// Get calendars id
calendarId = new int[cursor.getCount()];
for (int i = 0; i < calendarNames.length; i++)
{
calendarId[i] = cursor.getInt(0);
calendarNames[i] = cursor.getString(1);
cursor.moveToNext();
}
Step 2:
After getting the name and id of the calendar, we need to add the event
ContentValues contentEvent = new ContentValues();
// Particular Calendar in which we need to add Event
contentEvent.put("calendar_id", calendarIds[0]);
// Title/Caption of the Event
contentEvent.put("title", "Wedding");
// Description of the Event
contentEvent.put("description", "Wedding Party");
// Venue/Location of the Event
contentEvent.put("eventLocation", "New York");
// Start Date of the Event with Time
contentEvent.put("dtstart", StartDate);
// End Date of the Event with Time
contentEvent.put("dtend", EndDate);
// All Day Event
contentEvent.put("allDay", 1);
// Set alarm for this Event
contentEvent.put("hasAlarm",1);
Uri eventsUri = Uri.parse("content://com.android.calendar/events");
// event is added successfully
getContentResolver().insert(eventsUri, contentEvent);
cursor.close();
Step 3:
If you like to delete the event means we can use this code
getContentResolver().delete(Uri.parse("content://com.android.calendar/events"), "calendar_id=? and description=? and eventLocation=? ", new String[]{String.valueOf(calendarIds[0]), "Wedding Party", "New York"});
The same event can be insert or delete in 2.1, for that we can use like this
Step 1:
For this we can use the same code as mentioned in the Step 1 of 2.2 version.
Step 2:
We need to change the path as "content://calendar/calendars" from "content://com.android.calendar/calendars"
Step 3:
Don't take the above 2.2 version code, we need to use like this
Uri CALENDAR_URI = Uri.parse("content://calendar/events");
Cursor cursors = getContentResolver().query(CALENDAR_URI, null, null, null, null);
if (cursors.moveToFirst())
{
while (cursors.moveToNext())
{
String desc = cursors.getString(cursors.getColumnIndex("description"));
String location = cursors.getString(cursors.getColumnIndex("eventLocation"));
// event id
String id = cursors.getString(cursors.getColumnIndex("_id"));
if ((desc==null) && (location == null))
{
}
else
{
if (desc.equals("Birthday Party") && location.equals("Delhi"))
{
Uri uri = ContentUris.withAppendedId(CALENDAR_URI, Integer.parseInt(id));
getContentResolver().delete(uri, null, null);
}
}
}
}
