Question

在我的应用程序中，我使用了多个“警报管理器”，它们都工作正常。现在，我的应用中还需要两件事：

为每个alarmManager设置一个ID，以便我可以在广播接收器中识别此警报
使用此ID稍后取消警报

我的设置闹钟代码

    Calendar cal1 = Calendar.getInstance();
    cal1.set(Calendar.HOUR_OF_DAY, h1);
    cal1.set(Calendar.MINUTE, m1+30);
    cal1.set(Calendar.SECOND, 00);

    Intent intent = new Intent(context, YourBroadCastReceiver.class);


    // Add Some unique ID here for e.g "SFSF43535"
    PendingIntent openAlarm = PendingIntent.getBroadcast(context, 0, intent, 0);
     // Add Some unique ID here for e.g "SFSf87sfs"
    PendingIntent CloseAlarm = PendingIntent.getBroadcast(context, 0, intent, 0);

    AlarmManager alarmManager = (AlarmManager) context.getSystemService(ALARM_SERVICE);

    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                      cal1.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, openAlarm);

   alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                      cal1.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, CloseAlarm);

YourBroadCastReceiver （这里我需要唯一的ID）

  @Override
    public void onReceive(Context context, Intent intent) {
       // Get Unique id here to find some data related to that alram 
    }

Answer 1

您可以在Intent中添加附加内容，这些附加内容将被传递：

Intent intent = new Intent(context, YourBroadCastReceiver.class);
intent.putExtra("id", "somerandomID");

然后将多余的东西退回接收器：

public void onReceive(Context context, Intent intent) {
      String id = intent.getStringExtra("id");

Answer 2

    Intent intentOpen = new Intent(context, YourBroadCastReceiver.class);
    intentOpen.putExtra("id", 1);
    PendingIntent openAlarm = PendingIntent.getBroadcast(context, 0, intentOpen, 0);

    Intent intentClose = new Intent(context, YourBroadCastReceiver.class);
    intentClose.putExtra("id", 2);
    PendingIntent CloseAlarm = PendingIntent.getBroadcast(context, 0, intentClose, 0);

并在收到后

public void onReceive(Context context, Intent intent) {
      int AlarmId = intent.getExtras().getInt("id");
      if(AlarmId==1)
      {
      }else if(AlarmId==2)
      {
          //Cancle
          Intent myIntent = new Intent(context, AlarmReceiver.class);
          PendingIntent pendingIntent = PendingIntent.getActivity(context,
            AlarmId, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    AlarmManager manager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

    pendingIntent.cancel();
    manager.cancel(pendingIntent);
      }
}

Android设置了具有唯一ID的闹钟
