无法取消Android Alarm Manager

我正在尝试使用我的应用设置多个闹钟,并根据请求取消它们。

我已经阅读了很多关于相同的主题,并浏览了文档,但似乎它不起作用。

文档说,取消将尝试找到与我提供的“ filterEquals ”匹配的意图('确定两个意图是否相同,以达到意图解析(过滤)的目的。是,如果他们的行为,数据,类型,类和类别是相同的。这不会比较意图中包含的任何额外数据。')

我提供相同的操作,数据,类型,类和类别,为什么它不起作用?

创建闹钟:

    AlarmManager manager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    int interval = 30000;

    Intent intent = new Intent(getApplicationContext(), Broadcast.class);        
    intent.putExtra("alarmTime",alarmTime);
    intent.putExtra("reminder1",reminder1);
    intent.putExtra("reminder2",reminder2);
    intent.putExtra("title",title);
    intent.putExtra("message",message);
    intent.putExtra("vibrate",vibrate);
    intent.putExtra("sound",sound);
    intent.putExtra("name",name);

    //Create _id from data input. is unique
    int _id = 0;
    for (char i: name.toCharArray()){
        _id += Character.getNumericValue(i);
    }
    for (char i:title.toCharArray()){
        _id += Character.getNumericValue(i);
    }
    for (char i:message.toCharArray()){
        _id += Character.getNumericValue(i);
    }
    _id += (int) alarmTime.getTime();
    _id += (int) reminder1.getTime();
    _id += (int) reminder2.getTime();
    Log.e("ALARMS", "Creating alarm with id: "+_id);
    intent.setData(Uri.parse("custom://" + _id));
    intent.setAction(String.valueOf(_id));
    PendingIntent pendingUpdateIntent = PendingIntent.getBroadcast(getApplicationContext(), _id, intent, 0);

    manager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() + interval, pendingUpdateIntent);

取消闹钟

AlarmManager manager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(getApplicationContext(), Broadcast.class);
    intent.putExtra("alarmTime",alarmTime);
    intent.putExtra("reminder1",reminder1);
    intent.putExtra("reminder2",reminder2);
    intent.putExtra("title",title);
    intent.putExtra("message",message);
    intent.putExtra("vibrate",vibrate);
    intent.putExtra("sound",sound);
    intent.putExtra("name",name);

    int _id = 0;
    for (char i:name.toCharArray()){
        _id += Character.getNumericValue(i);
    }
    for (char i:title.toCharArray()){
        _id += Character.getNumericValue(i);
    }
    for (char i:message.toCharArray()){
        _id += Character.getNumericValue(i);
    }
    _id += (int) alarmTime.getTime();
    _id += (int) reminder1.getTime();
    _id += (int) reminder2.getTime();
    intent.setData(Uri.parse("custom://" + _id));
    intent.setAction(String.valueOf(_id));
    PendingIntent pendingUpdateIntent = PendingIntent.getBroadcast(getApplicationContext(), _id, intent, 0);
    Log.e("ALARMS", "Cancelling alarm with id: "+_id);
    // Cancel alarms
    try {
        manager.cancel(pendingUpdateIntent);
    } catch (Exception e) {
        Log.e("ALARMS", "AlarmManager update was not canceled. " + e.toString());
    }

所以我用不同的参数调用3次创建闹钟,所以我的_id每次都不同。

然后我拨打3次取消警报,并在创建和取消时为每个警报生成匹配。

所以取消运行但我的警报仍然被解雇。

我的闹钟会触发广播接收器,每个闹钟都会输出一个通知。

我忘了提到我尝试使用 PendingIntent 的不同标志但没有工作(FLAG_CANCEL_CURRENT,FLAG_UPDATE_CURRENT)
