闹钟没有停止

我试图停止警报并检查它是否停止，但它总是返回 true 意味着警报正在工作。我尝试根据链接中的答案停止警报https://stackoverflow.com/a/17616299/1226882但这对我不起作用。

请参考下面的代码

• 启动警报

  public static void startSchedulerAlaram(Context ctx) {
  
  Calendar calendar = Calendar.getInstance();
  calendar.setTimeInMillis(System.currentTimeMillis());
  calendar.set(Calendar.HOUR_OF_DAY, 0); 
  calendar.set(Calendar.MINUTE, 0);
  calendar.set(Calendar.SECOND, 0);
  calendar.set(Calendar.MILLISECOND, 0);
  
  if (calendar.compareTo(Calendar.getInstance()) <= 0)
      calendar.add(Calendar.DATE, 1);
  
  AlarmManager alarmManager = (AlarmManager) ctx
          .getSystemService(Context.ALARM_SERVICE);
  
  Intent intent = new Intent(ctx, Alaram_Receiver.class);
  intent.setAction(Utility.SCHEDULE_ACTION);
  
  PendingIntent pi = PendingIntent.getBroadcast(ctx, 1, intent,0);
  alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
  calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY, pi);
  
  log("Scheduler Alarm", "Started");
  
  }
  

• 停止报警

  public static void stopSchedulerAlaram(Context ctx) {
  
  Intent intent = new Intent(ctx, Alaram_Receiver.class);
  intent.setAction(Utility.SCHEDULE_ACTION);
  PendingIntent pendingIntent = PendingIntent.getBroadcast(ctx, 1,
          intent, PendingIntent.FLAG_UPDATE_CURRENT);
  AlarmManager alarmManager = (AlarmManager) ctx
          .getSystemService(Context.ALARM_SERVICE);
  alarmManager.cancel(pendingIntent);
  
  log("Scheduler Alarm", "Stopped");
  }
  

• 检查报警

  public static boolean checkSchedulerAlaram(Context ctx) {
  
  boolean alarmUp = (PendingIntent.getBroadcast(ctx, 1, new Intent(ctx,Alaram_Receiver.class).setAction(Utility.SCHEDULE_ACTION),
          PendingIntent.FLAG_NO_CREATE) != null);
  
  return alarmUp;
  }
  

你必须通过different id for set alarm

PendingIntent.getBroadcast(ctx, id, intent,PendingIntent.FLAG_UPDATE_CURRENT);

For cancel alarm you have pass sameidthat you used for set.

PendingIntent pendingIntent = PendingIntent.getBroadcast(ctx, id,
        intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) ctx
        .getSystemService(Context.ALARM_SERVICE);
alarmManager.cancel(pendingIntent);
