如何使用 PendingIntent 在 BroadCastReceiver 类上发送额外内容？

Question

我需要你的帮助！当我在 Intent 中添加额外内容然后使用该 Intent 创建 Pending Intent 时，它不起作用！我没有进入 BroadCastReceiver 课程。

public class Recordatori_Visita extends Activity {
    public void setAlarm(Calendar targetCal) {

        Intent intent = new Intent (Recordatori_Visita.this, Receiver.class);
        Long targetCal2 = targetCal.getTimeInMillis();  
        intent.putExtra("targetCal",targetCal2);
        intent.putExtra("n",n);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(Recordatori_Visita.this, 1, intent, intent.FILL_IN_DATA);

        AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
        alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(),pendingIntent);
    }
}

.

public class Receiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context k1, Intent k2) {
    // TODO Auto-generated method stub 

        Bundle bolsaR = k2.getExtras();
        Long extras = bolsaR.getLong("targetCalKey");
        int n= bolsaR.getInt("n");

        NotificationManager notificationManager = (NotificationManager) k1.getSystemService(Context.NOTIFICATION_SERVICE);
        ...
        notificationManager.notify(1,myNotification);

   }
}

我已经把代码删了，所有用到的变量都创建好了，我找不到解决办法。如果我没有在意图中放入额外的数据，它可以正常工作，但是当我 putExtra 时它不起作用，因为没有通知。谢谢！！

尝试将系统时间作为requestCode 放入getBroadcast() 函数中。

int requestID = (int) System.currentTimeMillis();
PendingIntent pendingIntent = PendingIntent.getBroadcast(Recordatori_Visita.this, requestID, intent, intent.FILL_IN_DATA);
