警报未决意图一次又一次地被调用

Question

我在我目前正在进行的项目中添加了警报。他们在我所有的条件下都工作得很好。面对一个小问题。我添加了一个一次性警报，我希望它按时触发，它工作正常，并且在到达时间后打开一个 activity，其中包含我通过意图发送的值。问题是即使在警报被触发后，挂起的意图也会被再次调用，当我关闭 activity 时它会打开带有空值的 activity 它再次弹出与我关闭它一样多的次数。未决意图在指定时间触发后不会被取消。下面是我设置闹钟的代码。

public void setAlarm(int hours, int minutes,String AMPM, String alarmType,String message, String extraMessage)
    {

        Random rand = new Random();
        int  n = rand.nextInt(10000) + 1;
        Log.e("HMA",hours+"   "+minutes+"   "+AMPM + " " + message + extraMessage);

//                       Toast.makeText(getApplicationContext(), "Alarm On",
        //   Toast.LENGTH_SHORT).show();
        Calendar calendar = Calendar.getInstance();
        // set selected time from timepicker to calendar
        calendar.set(Calendar.HOUR_OF_DAY, hours);
        calendar.set(Calendar.MINUTE,minutes);
        calendar.set(Calendar.SECOND,00);


        if(AMPM.equals("PM")) {
            Log.e("PM","");
            calendar.set(Calendar.AM_PM, Calendar.PM);
        }
        else
        {
            calendar.set(Calendar.AM_PM, Calendar.AM);
        }
        Intent myIntent = new Intent(this,
                MyReceiver.class);
        AlarmManager alarmManager;
        alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

        myIntent.putExtra("alarmType",alarmType);
        myIntent.putExtra("gifMessage",message);
        myIntent.putExtra("extraMessage",extraMessage);


        PendingIntent pendingIntent;

        // A PendingIntent specifies an action to take in the
        // future
        pendingIntent = PendingIntent.getBroadcast(
                this, n, myIntent, 0);

        // set alarm time
        if(Build.VERSION.SDK_INT<19) {
            alarmManager.set(AlarmManager.RTC,
                    calendar.getTimeInMillis(), pendingIntent);
        }
        else if(Build.VERSION.SDK_INT>=19 && Build.VERSION.SDK_INT<=22)
        {
            alarmManager.setExact(AlarmManager.RTC,
                    calendar.getTimeInMillis(), pendingIntent);
        }
        else if(Build.VERSION.SDK_INT>=23)
        {
            alarmManager.setExactAndAllowWhileIdle(AlarmManager.RTC,
                    calendar.getTimeInMillis(), pendingIntent);
        }
    }

我使用 IntentService 而不是 Service 解决了它，并在 onStartCommand 中返回 START_NOT_STICKY。
