好的，这是Alarm Manager的模式。在此实现中，没有使用静态定义的广播接收器，也不应该用于调度任务，根据Android O最佳实践，简而言之， FORGET关于广播接收器如果您想要背景通知。
1）创建意向服务（ex.ReminderAlarmService）以发布您的通知。此服务将以alarmManager使用的待处理意图启动。 onHandleIntent应该创建通知并显示它：ex。
ReminderAlarmService.class
@Override
protected void onHandleIntent(Intent intent) {
//..... Create your notification here
manager.notify(NOTIFICATION_ID, notification);
//..... Persist your data here in sharedPreferences here too, with or without user action
}
2）在服务中，创建一个公共util方法来返回“操作”待定意图以启动上述意图服务（也称为深层链接意图）ex。
public static PendingIntent getReminderPendingIntent(Context context, Uri uri) {
Intent action = new Intent(context, ReminderAlarmService.class);
action.setData(uri);
return PendingIntent.getService(context, 0, action, PendingIntent.FLAG_UPDATE_CURRENT);
}
3）创建一个util类以获取警报管理器的实例，使用它来设置时间和使用上述方法创建的“操作”意图。操作意图启动意图服务，该服务执行onHandleIntent中的任何操作。离。
public class AlarmScheduler {
public static void scheduleAlarm(Context context, long alarmTime, Uri reminderTask) {
AlarmManager manager = AlarmManagerProvider.getAlarmManager(context);
PendingIntent operation =
ReminderAlarmService.getReminderPendingIntent(context, reminderTask);
manager.setExact(AlarmManager.RTC, time, operation);
}
}
