android - 如何在 Android 中使用闹钟管理器进行生日提醒？从 SQLite 数据库中读取日期

Question

用什么设置每年重复的闹钟？

Answer 1

嘿，这是如何将 android AlarmManager 上的警报设置为特定日期（android alarmmanager 设置警报日期）我一直在寻找这个。注意月值！！

Calendar cal = Calendar.getInstance(TimeZone.getDefault(), Locale.getDefault());
//cal.add(Calendar.SECOND, 10);

cal.set(Calendar.DATE,19);  //1-31
cal.set(Calendar.MONTH,Calendar.DECEMBER);  //first month is 0!!! January is zero!!!
cal.set(Calendar.YEAR,2012);//year...

cal.set(Calendar.HOUR_OF_DAY, 16);  //HOUR
cal.set(Calendar.MINUTE, 39);       //MIN
cal.set(Calendar.SECOND, 10);       //SEC


// Create a new PendingIntent and add it to the AlarmManager
Intent intent = new Intent(MainActivity.this, alarmAct.class);
PendingIntent pendingIntent = PendingIntent.getService(MainActivity.this, 0,intent, 0);

//or if you start an Activity
//PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 0,intent, 0);

AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);

Answer 2

使用警报管理器的 setRepeating 方法和

添加您从 db 获取的确切日期的一年

Calendar today_plus_year = Calendar.getInstance();  
today_plus_year.add( Calendar.YEAR, 1 );  

之后将其转换为毫秒并传递给警报管理器 setRepeat 方法

alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);

Answer 3

 Intent myIntent = new Intent(Main.this, MyAlarmService.class);
 pendingIntent = PendingIntent.getService(Main.this, 0, myIntent, 0);

    AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);

    Calendar cal = Calendar.getInstance();

    cal.setTimeInMillis(System.currentTimeMillis());
    cal.clear();
    cal.set(2012,5,20,18,40);

    alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);  

Answer 4

     if (cDate.equals(dbDate)) {
    Log.i("TODAY", "Dates Matched");
    Log.i("TIME MATCHED", "Currently in AM");
    cal.set(Calendar.HOUR_OF_DAY, hour);
    cal.set(Calendar.MINUTE, minutes);
    cal.set(Calendar.SECOND, 0);
    Intent intent = new Intent(this, AlarmReciever.class);
    PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), 0,intent,
                    PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
    // am.setRepeating(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(),
        AlarmManager.INTERVAL_FIFTEEN_MINUTES, operation);

    am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pi);
    } 
   else {

   }
}
