如何禁止下拉通知栏。

如何使用以下方法取消通知：

我尝试了Android的Lollipop和牛轧糖，但通知栏都没有恢复。如果有人能告诉我这是不是可能的以及怎么做。多谢了。

生成通知的代码：

NotificationCompat.Builder builder = new NotificationCompat.Builder(this);

    builder
            .setSmallIcon(icon).setTicker(message).setWhen(when)
            .setAutoCancel(true).setContentTitle("Kindly record your Voice")
            .setColor(Color.RED);


    notificationIntent = new Intent(this,ReminderReceiver.class);
    notificationIntent.setAction("Record");
    PendingIntent pendIntent1 = PendingIntent.getBroadcast(getApplicationContext(), 1, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    builder.addAction(R.drawable.common_google_signin_btn_icon_dark, "Record", pendIntent1);


    notificationIntent2 = new Intent(this, ReminderReceiver.class);
    notificationIntent2.setAction("Dismissed");

    PendingIntent pendIntent2 = PendingIntent.getBroadcast(getApplicationContext(), 1, notificationIntent2, PendingIntent.FLAG_UPDATE_CURRENT);
    builder.addAction(R.drawable.starticon, "Dismiss", pendIntent2);

    notificationIntent3 = new Intent(this, CancelReceiver.class);
    PendingIntent pendIntent3 = PendingIntent.getBroadcast(getApplicationContext(), 1, notificationIntent3, PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setDeleteIntent(pendIntent3);

    notification = builder.build();


    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notificationManager.notify(1, notification);

可能看起来很奇怪，但当存在其他通知时，通知栏不会上升。如果您的是唯一的通知，则点击后，条形图会自动上滑。
