java - 如何创建不可删除的通知？

Question

这是我的源代码。我需要，让它不可删除 - 它应该在点击后删除，而不是通过在通知管理器中滑动。是否可以？

Intent intent = new Intent(this, SecondActivity.class);
intent.putExtra("NotiClick", true);
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN) {
        Notification Noti;
        Noti = new Notification.Builder(this)
                .setContentTitle("Dont Lose It")
                .setContentText("Stop monitoring by click!")
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentIntent(pIntent)
                .setAutoCancel(true).build();

        NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

        notificationManager.notify(0, Noti);
    }`

您需要使用 setOngoing(true)使用您的 Notification.Builder:

Set whether this is an "ongoing" notification. Ongoing notifications cannot be dismissed by the user, so your application or service must take care of canceling them. They are typically used to indicate a background task that the user is actively engaged with (e.g., playing music) or is pending in some way and therefore occupying the device (e.g., a file download, sync operation, active network connection).
