Android AlarmManager不會取消相同的Intents

在過去的兩天裏，我一直在試圖讓AlarmManager取消之前設置的鬧鈴，由於某些原因我無法使它工作。Android AlarmManager不會取消相同的Intents

我已經搜索了這個問題，最常見的解決方案是跟蹤舊的意圖，因爲只有那些，他們是可以取消的。

爲了解決這個問題，我決定創建我自己的Intent類，它是Serializable。

然後我將Intent類保存到一個「Intent.ser」文件中，然後調用那些來取消我的警報。

SerUitvalIntent.java

public class SerUitvalIntent extends Intent implements Serializable 
{ 

private String klas; 
private int delay; 
private Boolean uitvalBuzz; 
private Boolean algemeenBuzz; 

public SerUitvalIntent(Context context, Class<?> class1) 
{ 
    super(context, class1); 
} 

public void setBundle(Bundle b) 
{ 
    klas = b.getString(someClass.KLAS); 
    delay = b.getInt(someClass.DELAY); 
    uitvalBuzz = b.getBoolean(someClass.UITVALBUZZ); 
    algemeenBuzz = b.getBoolean(someClass.ALGEMEENBUZZ); 
} 

public Bundle getBundle() 
{ 
    Bundle b = new Bundle(); 
    b.putBoolean(someClass.UITVALBUZZ, uitvalBuzz); 
    b.putBoolean(someClass.ALGEMEENBUZZ, algemeenBuzz); 
    b.putString(someClass.KLAS, klas); 
    b.putInt(someClass.DELAY, delay); 
    return b; 
} 

/** 
* 
*/ 
private static final long serialVersionUID = 8289838097824161902L; 
}

someClass.java

public static void schedule(Context context, long delay, Bundle data, Boolean startup) 
{ 
    DataHandler dHandle = new DataHandler(context, false); 
    final AlarmManager alarm = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); 

    SerUitvalIntent oldIntent = dHandle.getAlarm(); 

    if(oldIntent != null) 
    { 
     oldIntent.putExtra(BUNDLE, oldIntent.getBundle()); 
     oldIntent.putExtra(FROMUI, false); 
     Bundle b = oldIntent.getBundle(); 
     Log.i("AlarmManagerUitval", "Cancelled " + b.getString(KLAS) + "." + b.getInt(DELAY) + "." + b.getBoolean(UITVALBUZZ) + " alarm"); 
     final PendingIntent oldPending = PendingIntent.getService(context, 0, oldIntent, 0); 
     //Cancel latest alarm 
     alarm.cancel(oldPending); 
    } 


    final SerUitvalIntent intent = new SerUitvalIntent(context, UitvalService.class); 
    intent.setBundle(data); 
    dHandle.setAlarm(intent); 

    intent.putExtra(BUNDLE, data); 
    intent.putExtra(FROMUI, false); 

    final PendingIntent pending = PendingIntent.getService(context, 0, intent, 0); 

    Log.i("AlarmManagerUitval", "Started " + data.getString(KLAS) + "." + data.getInt(DELAY) + "." + data.getBoolean(UITVALBUZZ) + " alarm"); 
    long time; 

    if(startup) 
    { 
     time = SystemClock.elapsedRealtime(); 
    } 
    else 
    { 
     time = SystemClock.elapsedRealtime()+delay; 
    } 
    alarm.setRepeating(AlarmManager.ELAPSED_REALTIME, time,delay, pending); 
}

我的logcat示出當警報被設置和取消相同的數據（Log.i（）示出相同的數據），但不知何故它不會取消。
