使用“Intent.putExtra()"的方式将带有提醒的事件添加到日历 [英] Adding event with reminders to calendar with 'Intent.putExtra()' way of doing
问题描述
我正在尝试使用以下代码将事件添加到日历:
I'm trying to add events to calendar with the following code :
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;
}
然后使用以下命令启动操作:startActivity(mTask.calPopulation());
And then launch the action with : startActivity(mTask.calPopulation());
我没有任何问题,日历应用事件启动时使用了我在应用中输入的正确信息,只是它没有填写我要添加的提醒事件.
I don't have any issue, the calendar app event launched with the correct information I entered into my app, except that it does not fill in the event the reminder I would like to add.
你有什么线索吗?我尝试使用这种方法(我的意思是intent.putExtra)在许多线程中搜索,但从未找到任何有趣的东西.
Do you have any clues? I tried to search within many threads using this method (I mean the intent.putExtra) but never find anything interesting.
另外一点,有没有办法直接将事件+提醒保存到日历中,而无需打开日历App并请求用户操作?
Other point, is there a way to directly save the event + reminder into the calendar without opening calendar App and requesting for user action?
提前致谢.亚历克斯.
推荐答案
按照我指出的方法没有答案,但是我找到了另一种方法,可以在日历中添加带有提醒的事件.
No answer according to the method I pointed out, but another way I found to add event with reminders to the calendar.
以下方法对我来说效果很好:
Hereunder methods are working fine for me :
// 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:).
Hope this could help others that encountered the same problem I had :).
