notification opening a new window no matter what in Java Android

I want to launch a notification. When I click on it, it opens a NEW window of the app. Here's my code:

public class Noficitation开发者_如何学Python extends Activity {

NotificationManager nm;
static final int uniqueID = 1394885;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    Intent intent= new Intent (Intent.ACTION_MAIN);
    intent.setClass(getApplicationContext(), SchoolBlichActivity.class);
    PendingIntent pi=PendingIntent.getActivity(this, 0, intent, 0);
    String body = " body";
    String title = "title!";
    Notification n =new Notification(R.drawable.table, body, System.currentTimeMillis());
    n.setLatestEventInfo(this, title, body, pi);
    n.defaults = Notification.DEFAULT_ALL;
    n.flags = Notification.FLAG_AUTO_CANCEL;
    nm.notify(uniqueID,n);
    finish();
}

by the way, if i add nm.cancel(uniqueID) before the finish(), it creates the notification and immediately deletes it...

Thanks for the help :D

You might want to just add a notification in the notification bar, and when the user clicks it, it will launch the actual Activity. This way the user won't be interrupted in whatever he's doing.

Create the status bar notification like this:

NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.notification_icon, "Hello", System.currentTimeMillis());

Intent notificationIntent = new Intent(this, myclass.class);
notification.setLatestEventInfo(getApplicationContext(), "My notification", "Hello world!", notificationIntent, PendingIntent.getActivity(this, 0, notificationIntent, 0));

mNotificationManager.notify(1, notification);

Are you just trying to open a notification window in a current activity? Because if you are I dont think you need to launch it with an intent. You normally only use intents to launch new services or activities in your app unless youve built a custom view and activity/service which is to take place within the notification box. I see you have it set up in its own class which is fine but I think the way your doing it by default would open an entire new view.

If you need to launch a notification during a process or something like a button click you dont need to have the intent there.....or at least I never did :) What exactly are you trying to achieve with the notification.
