如何在一年中的特定日期创建提醒通知？

Question

[我试图在一年中的特定日期向我的应用程序用户发送通知，而我被困在中间位置，因为我是按固定基准（每天，每周，..）安排通知的，所以我不想那。

这里是代码：

  Calendar cal = Calendar.getInstance();              
Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setType("vnd.android.cursor.item/event");
intent.putExtra("beginTime", cal.getTimeInMillis());
intent.putExtra("allDay", false);
intent.putExtra("rrule", "FREQ=DAILY");
intent.putExtra("endTime", cal.getTimeInMillis()+60*60*1000);
intent.putExtra("title", "A Test Event from android app");
startActivity(intent);

    private String getCalendarUriBase(Activity act) {

    String calendarUriBase = null;
    Uri calendars = Uri.parse("content://calendar/calendars");
    Cursor managedCursor = null;
    try {
        managedCursor = act.managedQuery(calendars, null, null, null, null);
    } catch (Exception e) {
    }
    if (managedCursor != null) {
        calendarUriBase = "content://calendar/";
    } else {
        calendars = Uri.parse("content://com.android.calendar/calendars");
        try {
            managedCursor = act.managedQuery(calendars, null, null, null, null);
        } catch (Exception e) {
        }
        if (managedCursor != null) {
            calendarUriBase = "content://com.android.calendar/";
        }
    }
    return calendarUriBase; }

    // get calendar
Calendar cal = Calendar.getInstance();     
Uri EVENTS_URI = Uri.parse(getCalendarUriBase(this) + "events");
ContentResolver cr = getContentResolver();

// event insert
ContentValues values = new ContentValues();
values.put("calendar_id", 1);
values.put("title", "Reminder Title");
values.put("allDay", 0);
values.put("dtstart", cal.getTimeInMillis() + 11*60*1000); // event starts at 11 minutes from now
values.put("dtend", cal.getTimeInMillis()+60*60*1000); // ends 60 minutes from now
values.put("description", "Reminder description");
values.put("visibility", 0);
values.put("hasAlarm", 1);
Uri event = cr.insert(EVENTS_URI, values);

// reminder insert
Uri REMINDERS_URI = Uri.parse(getCalendarUriBase(this) + "reminders");
values = new ContentValues();
values.put( "event_id", Long.parseLong(event.getLastPathSegment()));
values.put( "method", 1 );
values.put( "minutes", 10 );
cr.insert( REMINDERS_URI, values );

清单

<uses-permission android:name="android.permission.READ_CALENDAR" />
<uses-permission android:name="android.permission.WRITE_CALENDAR" />

但是我想在一年中的某个特定日期创建提醒通知，而不是定期（每天，每周等）。我该如何编写代码？

Answer 1

使用AlarmManager。像这样的东西：

Calendar cal = Calendar.getInstance();
cal.setTime(...);

Intent i = new Intent(context, YourBroadcastReceiver.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0);

AlarmManager mgr = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pi);

Answer 2

您可以为此目的使用alarmManager服务！
