我尝试使用以下代码向日历添加事件:
public Intent calPopulation()
{
Intent calIntent = new Intent(Intent.ACTION_INSERT);
calIntent.setType("vnd.android.cursor.item/event");
calIntent.putExtra(CalendarContract.Events.TITLE, this._title);
GregorianCalendar calDate = new GregorianCalendar(this._year,this._month, this._day, this._hour, this._minute);
calIntent.putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, calDate.getTimeInMillis());
calIntent.putExtra(CalendarContract.EXTRA_EVENT_END_TIME, calDate.getTimeInMillis()+60*60*1000);
calIntent.putExtra(CalendarContract.Events.HAS_ALARM, true);
calIntent.putExtra(CalendarContract.Reminders.EVENT_ID, CalendarContract.Events._ID);
calIntent.putExtra(CalendarContract.Events.ALLOWED_REMINDERS, "METHOD_DEFAULT");
calIntent.putExtra(CalendarContract.Reminders.METHOD, CalendarContract.Reminders.METHOD_ALERT);
calIntent.putExtra(CalendarContract.Reminders.MINUTES,5);
return calIntent;
}
然后使用:startActivity(mTask.calPopulation());
我没有任何问题,使用我输入到我的应用中的正确信息启动了日历应用事件,但它没有填写我想添加的提醒事件。
你有任何线索吗?我尝试使用这种方法在很多线程中搜索(我的意思是intent.putExtra),但从未找到任何有趣的东西。其他方面,有没有办法直接将活动+提醒保存到日历中而无需打开日历应用程序并请求用户操作?
提前致谢。 亚历克斯。

根据我指出的方法没有答案,但我发现另一种方法是在日历中添加提醒事件。
以下方法对我来说很好:
// Add an event to the calendar of the user.
public void addEvent(Context context) {
GregorianCalendar calDate = new GregorianCalendar(this._year, this._month, this._day, this._hour, this._minute);
try {
ContentResolver cr = context.getContentResolver();
ContentValues values = new ContentValues();
values.put(CalendarContract.Events.DTSTART, calDate.getTimeInMillis());
values.put(CalendarContract.Events.DTEND, calDate.getTimeInMillis()+60*60*1000);
values.put(CalendarContract.Events.TITLE, this._title);
values.put(CalendarContract.Events.CALENDAR_ID, 1);
values.put(CalendarContract.Events.EVENT_TIMEZONE, Calendar.getInstance()
.getTimeZone().getID());
System.out.println(Calendar.getInstance().getTimeZone().getID());
Uri uri = cr.insert(CalendarContract.Events.CONTENT_URI, values);
// Save the eventId into the Task object for possible future delete.
this._eventId = Long.parseLong(uri.getLastPathSegment());
// Add a 5 minute, 1 hour and 1 day reminders (3 reminders)
setReminder(cr, this._eventId, 5);
setReminder(cr, this._eventId, 60);
setReminder(cr, this._eventId, 1440);
} catch (Exception e) {
e.printStackTrace();
}
}
// routine to add reminders with the event
public void setReminder(ContentResolver cr, long eventID, int timeBefore) {
try {
ContentValues values = new ContentValues();
values.put(CalendarContract.Reminders.MINUTES, timeBefore);
values.put(CalendarContract.Reminders.EVENT_ID, eventID);
values.put(CalendarContract.Reminders.METHOD, CalendarContract.Reminders.METHOD_ALERT);
Uri uri = cr.insert(CalendarContract.Reminders.CONTENT_URI, values);
Cursor c = CalendarContract.Reminders.query(cr, eventID,
new String[]{CalendarContract.Reminders.MINUTES});
if (c.moveToFirst()) {
System.out.println("calendar"
+ c.getInt(c.getColumnIndex(CalendarContract.Reminders.MINUTES)));
}
c.close();
} catch (Exception e) {
e.printStackTrace();
}
}
// function to remove an event from the calendar using the eventId stored within the Task object.
public void removeEvent(Context context) {
ContentResolver cr = context.getContentResolver();
int iNumRowsDeleted = 0;
Uri eventsUri = Uri.parse(CALENDAR_URI_BASE+"events");
Uri eventUri = ContentUris.withAppendedId(eventsUri, this._eventId);
iNumRowsDeleted = cr.delete(eventUri, null, null);
Log.i(DEBUG_TAG, "Deleted " + iNumRowsDeleted + " calendar entry.");
}
public int updateEvent(Context context) {
int iNumRowsUpdated = 0;
GregorianCalendar calDate = new GregorianCalendar(this._year, this._month, this._day, this._hour, this._minute);
ContentValues event = new ContentValues();
event.put(CalendarContract.Events.TITLE, this._title);
event.put("hasAlarm", 1); // 0 for false, 1 for true
event.put(CalendarContract.Events.DTSTART, calDate.getTimeInMillis());
event.put(CalendarContract.Events.DTEND, calDate.getTimeInMillis()+60*60*1000);
Uri eventsUri = Uri.parse(CALENDAR_URI_BASE+"events");
Uri eventUri = ContentUris.withAppendedId(eventsUri, this._eventId);
iNumRowsUpdated = context.getContentResolver().update(eventUri, event, null,
null);
// TODO put text into strings.xml
Log.i(DEBUG_TAG, "Updated " + iNumRowsUpdated + " calendar entry.");
return iNumRowsUpdated;
}
希望这可以帮助遇到同样问题的其他人:)。

同意上述答案,但重要的是日历ID。您不能使用1,因为三星手机使用1作为他们的日历(S Planner)。因此,日历ID是您希望事件发送的电子邮件的ID。您可以通过以下特定事件的代码来获取日历ID
int calenderId=-1;
String calenderEmaillAddress="xxx@gmail.com";
String[] projection = new String[]{
CalendarContract.Calendars._ID,
CalendarContract.Calendars.ACCOUNT_NAME};
ContentResolver cr = activity.getContentResolver();
Cursor cursor = cr.query(Uri.parse("content://com.android.calendar/calendars"), projection,
CalendarContract.Calendars.ACCOUNT_NAME + "=? and (" +
CalendarContract.Calendars.NAME + "=? or " +
CalendarContract.Calendars.CALENDAR_DISPLAY_NAME + "=?)",
new String[]{calenderEmaillAddress, calenderEmaillAddress,
calenderEmaillAddress}, null);
if (cursor.moveToFirst()) {
if (cursor.getString(1).equals(calenderEmaillAddress))
calenderId=cursor.getInt(0); //youre calender id to be insered in above answer
}
