通知栏里存储的数据，如何在启动的Activity里获取

nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);        n = new Notification(R.drawable.icon, "ABC", System.currentTimeMillis());        n.contentView = new RemoteViews(getPackageName(), R.layout.notification);        n.contentView.setTextViewText(R.id.notification_status_text, "start sending task: " + taskNumber);        n.contentView.setImageViewResource(R.id.notification_status_icon, R.drawable.icon);        intent = new Intent(NavigationActivity.this, MainTabActivity.class);        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP| Intent.FLAG_ACTIVITY_NEW_TASK);          Bundle bundle = new Bundle();        bundle.putBoolean("jump2queuelist", true);        intent.putExtras(bundle);        pendingIntent = PendingIntent.getActivity(NavigationActivity.this, 0,                intent, 0);        n.contentIntent = pendingIntent;        nm.notify(notification_id, n);

if(getIntent().getExtras().getBoolean("jump2queuelist", false)){            getIntent().getExtras().putBoolean("jump2queuelist", false);            showQueueHomeScreen();        }
