android - 删除报警 :Android

Question

这是我的 addAlarm() 方法:

Intent intent = new Intent(this, ALReciver.class);
 PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 10 , intent, PendingIntent.FLAG_UPDATE_CURRENT|  Intent.FILL_IN_DATA);

         AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

                alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(),pendingIntent );

此代码工作正常，但我想使用以下代码删除此警报:

 Intent intent = new Intent(this, ALReciver.class);
        PendingIntent sender = PendingIntent.getBroadcast(this,10, intent,PendingIntent.FLAG_CANCEL_CURRENT);

        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

        alarmManager.cancel(sender);

此代码无效..我不明白我做错了什么？

Answer 1

替换:

PendingIntent sender = PendingIntent.getBroadcast(this,10, intent,PendingIntent.FLAG_CANCEL_CURRENT);

到

PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 10 , intent, PendingIntent.FLAG_UPDATE_CURRENT|  Intent.FILL_IN_DATA);
