我正在尝试在 BOOT_COMPLETED 上从数据库中加载一些任务并为每个任务设置警报。警报管理器配置为接收 AndroidMANifest 文件中的 BOOT_COMPLETED。

有时我通过短信获得这些任务，所以我有一个用于短信接收和处理的 brodcastreceiver，它构建任务列表并调用 AlarmManager.setAlarms()。

我想知道当从 OnReceive() 方法 og SMSReceiver 调用时 setAlarams 工作正常，但在 Boot_Completed 上从 AlarmManager 的 OnReceive() 方法调用时不能正常工作。它只设置一个警报并忽略列表的其余部分！

有什么帮助吗？

public class AlarmManager extends BroadcastReceiver {
   @Override
   public void onReceive(Context context, Intent intent) {
        List <Task> taskList= db.loadFromDB();
        setAlarms(context, taskList);
   }


public static void setAlarms(Context context, List<Task> taskList) {
   for each task in taskList{
         int pendingIntentRequestCode = task.getid();;
         Intent myIntent = new Intent(context, AlarmReceiver.class);
         myIntent.putExtra("taskName", task.getName());
         myIntent.putExtra("taskHour", task.getHour));
         myIntent.putExtra("taskMinute", task.getMinute());
         PendingIntent pendingIntent = PendingIntent.getBroadcast(context,
              pendingIntentRequestCode,
              myIntent,
              PendingIntent.FLAG_UPDATE_CURRENT);

         AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
         alarmManager.set(AlarmManager.RTC_WAKEUP,alarmTime, pendingIntent );
   }
}
}




public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
     String taskName = intent.getStringExtra("taskName");
     int taskHour = intent.getIntExtra("taskHour", -1);
     int taskMinute = intent.getIntExtra("taskMinute", -1);


    Intent alarmIntent = new Intent(AlarmClock.ACTION_SET_ALARM);
    alarmIntent.putExtra(AlarmClock.EXTRA_MESSAGE, taskName);
    alarmIntent.putExtra(AlarmClock.EXTRA_HOUR, ataskHour);
    alarmIntent.putExtra(AlarmClock.EXTRA_MINUTES, taskMinute);
    alarmIntent.putExtra(AlarmClock.EXTRA_SKIP_UI, true);
    alarmIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(alarmIntent);

}

}


public class SMSReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    Bundle bundle = intent.getExtras();
    SmsMessage[] msgs = null;
    String messageReceived = "";
    if (bundle != null) {
        Object[] pdus = (Object[]) bundle.get("pdus");
        msgs = new SmsMessage[pdus.length];
        for (int i = 0; i < msgs.length; i++) {
            msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
            messageReceived += msgs[i].getMessageBody().toString();
            sender = msgs[i].getOriginatingAddress();
            messageReceived += "\n";
        }
            List <Task> taskList = MakeTaskListFromReceivedSMS(messageReceived);
            AlarmManager.setAlarms(context, taskList);
        }
    }
}

根据文档：

如果已经为同一个 IntentSender 安排了警报，它将首先被取消。
