AlarmManager - 如何将通知设置为每年出现

我想要根据输入的日期（生日）每年出现通知。我有其他一切工作栏，每年如何设置通知。正如你可以在下面看到的，我已经改变了代码在间隔时间去说“这里”。还有几天的时间间隔，我知道我可以乘上365，但如果发生什么闰年..AlarmManager - 如何将通知设置为每年出现

int REQUEST_CODE = 7; 
Intent intent = new Intent(Activity2.this, Receiver.class); 
PendingIntent pendingIntent = PendingIntent.getBroadcast(Activity2.this, REQUEST_CODE, intent, 0); 
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE); 
am.setRepeating(am.RTC_WAKEUP, System.currentTimeMillis(), HERE, pendingIntent);

请记住，每次设备重新启动时都需要重新创建警报，这一切都将在一年后得到保证。因此您需要创建一个'BroadcastReceiver'来侦听ACTION_BOOT_COMPLETED行为（并且您需要'RECEIVE_BOOT_COMPLETED'权限），并在每次启动时重置警报。 –

你可以与确定次年2月从今天起是闰年，然后替换方法“这里”返回值365或366天（以毫秒为单位介意你）基于这些检查。

private long millisUntilNextYear(){ 

    //Set days in a year for Leap and Regular 
    final int daysInLeapYear = 366; 
    final int daysInYear = 365; 

    //Get calendar instance 
    GregorianCalendar cal = (GregorianCalendar) GregorianCalendar.getInstance(); 

    //Get this year and next year 
    int thisYear = cal.get(GregorianCalendar.YEAR); 
    int nextYear = thisYear + 1; 

    //Get today's month 
    int thisMonth = cal.get(GregorianCalendar.MONTH); 

    //Get today's date 
    int dayOfMonth = cal.get(GregorianCalendar.DAY_OF_MONTH); 

    //Is today before February? If so then the following February is in THIS year 
    if (thisMonth < GregorianCalendar.FEBRUARY){ 

     //Check if THIS year is leapYear, and return correct days (converted to millis) 
     return cal.isLeapYear(thisYear) ? daysToMillis(daysInLeapYear) : daysToMillis(daysInYear); 
    } 

    //Is today after February? If so then the following February is NEXT year 
    else if (thisMonth > GregorianCalendar.FEBRUARY) { 
     //Check if NEXT year is leapYear, and return correct days (converted to millis) 
     return cal.isLeapYear(nextYear) ? daysToMillis(daysInLeapYear) : daysToMillis(daysInYear); 
    } 

    //Then today must be February. 
    else { 
     //Special case: today is February 29 
     if (dayOfMonth == 29){ 
      return daysToMillis(daysInYear); 
     } else { 
      //Check if THIS year is leapYear, and return correct days (converted to millis) 
      return cal.isLeapYear(thisYear) ? daysToMillis(daysInLeapYear) : daysToMillis(daysInYear); 
     } 
    } 
}

我仍然无法弄清楚这一点，但我知道你的意思！你能否进一步解释甚至给我一些示例代码？ @ user3829751 – Garth

已编辑，添加了代码示例，供您复制和粘贴乐趣:) – user3829751

1）保存MM/DD/YY格式的日期。

2）阅读这些日期当您打开您的应用程序（或在不同的时间）

3）单日的快讯/今天的自我。

另外，您也可以显示在生日下周/月等
