日曆提醒沒有在事件發生之前/之前發送通知

Question

此事件已在我的Google日曆中創建，但未按照代碼給出通知。它應該在活動開始時發出通知。在代碼中提到的所有條目都會在日曆中被反思，事件已創建，日曆顯示爲alrm：在事件發生時，但它仍未發出通知。 請幫我一下嗎？

public long MyCalendar() { 
     long calID = 1; 
     long startMillis = 0; 
     long endMillis = 0; 
     Calendar beginTime = Calendar.getInstance(); 
     beginTime.set(2015, 4, 29, 10, 51); 
     startMillis = beginTime.getTimeInMillis(); 
     Calendar endTime = Calendar.getInstance(); 
     endTime.set(2015, 4, 29, 8, 45); 
     endMillis = endTime.getTimeInMillis(); 
     String eventUriStr = "content://com.android.calendar/events"; 


     ContentResolver cr = getContentResolver(); 
     ContentValues values = new ContentValues(); 

     values.put(CalendarContract.Events.TITLE, "My party1"); 
     values.put(CalendarContract.Events.DESCRIPTION, "surprise party"); 
     values.put(CalendarContract.Events.CALENDAR_ID, calID); 
     TimeZone tz = TimeZone.getDefault(); 
     values.put(CalendarContract.Events.EVENT_TIMEZONE,tz.getID()); 
     values.put(CalendarContract.Events.DTSTART, startMillis); 
     values.put(CalendarContract.Events.DTEND, endMillis); 
     Uri uri = cr.insert(Uri.parse(eventUriStr), values); 

     long eventID = Long.parseLong(uri.getLastPathSegment()); 

     return eventID; 
    } 


    **And In onCreate() method of MainActivity, I am calling MyCalendar()** 

     protected void onCreate(Bundle savedInstanceState) { 
       super.onCreate(savedInstanceState); 
       setContentView(R.layout.activity_main); 
     long event_id1= MyCalendar(); 
       ContentResolver cr1 = getContentResolver(); 
       ContentValues values = new ContentValues(); 
       values.put(CalendarContract.Reminders.MINUTES, 0); 
       values.put(CalendarContract.Reminders.EVENT_ID, event_id1); 
       values.put(CalendarContract.Reminders.METHOD, CalendarContract.Reminders.METHOD_ALERT); 
       MainActivity.this.getContentResolver().insert(CalendarContract.Reminders.CONTENT_URI, values); 
     }

我有同樣的問題。我注意到，如果給出0值：values.put(CalendarContract.Reminders.MINUTES, 0); 將不會有通知。如果您給出0以外的任何一個，那麼通知就會出現。

values.put(CalendarContract.Reminders.MINUTES, 1);
