From Notification: AlertDialog without UI

Question

I'm creating a notification which fires an Intent. Here a really shortened excerpt of my code...

Notification notification = new Notification(R.drawable.icon, "notification", System.currentTimeMillis());
NotificationManager nm = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
Intent notificationIntent = new Intent(BackgroundService.this, ConnectionHandler.class);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
notificationIntent.addFlags(Intent.FLAG_FROM_BACKGROUND);

PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
notification.setLatestEventInfo(context, getString(R.string.notification_title), getString(R.string.notification_body), pendingIntent);
notification.flags |= notification.FLAG_AUTO_CANCEL;
nm.notify(1, notification);

In my intent (ConnectionHandler.class), I'd like to show an AlertDialog, which works. But I'd like the AlertDialog to show up without opening a new UI-Window. The best for me was if the AlertDialog simply appears without anything else when tapping the notification-entry.

Any idea is appreciated.

Regards, Tobi

From the Dev Guide:

Showing a Dialog

A dialog is always created and displayed as a part of an Activity.

The easy alternative is to create a very basic Activity, with nothing showing up except the dialog, and calling finish() as soon as the dialog is dismissed.

You can also give that Activity a translucent theme to keep anything but the dialog from showing up. – Marcus May 16 '11 at 22:25
bah that's bad that the dialog is part of an Activity. But `finish()`ing after dismission did the trick. Many thanks! – Atmocreations May 16 '11 at 22:27

Ah... nice! I'm sure I've seen it in an application once... So it's all about styling the activity. Thanks to you, too! Maybe I'll rebuild it to this solution. – Atmocreations May 17 '11 at 07:44
Thanks, but I think Aleadam's solution is better :) – pawelzieba May 17 '11 at 19:56

There's a very easy answer: the Activity CAN look like a dialog. In manifest add this:

android:theme="@android:style/Theme.Dialog"

And it will look like a dialog.

If you want to show up an Alert Dialog, use this code:

Activity
AlertDialog d = new AlertDialog.Builder(this).setTitle("Blah-Blah").setBlah().show()
Manifest
android:theme="@android:style/Theme.Translucent"
