You will need a Broadcast a intent and a Intent Receiver

Below is my create Notification code.
You will need to broadcast an intent when user clicks on notification icon.

    // create NotificationManager..
    NotificationManager mNotificationManager = (NotificationManager) this
            .getSystemService(Context.NOTIFICATION_SERVICE);

    Notification notification = new Notification(R.drawable.icon, null,
            System.currentTimeMillis());

    // create intent that will be broadcast.
    Intent i = new Intent();
    i.setClassName(this, BReceiver.class.getName());    
    i.setAction("Test");

    PendingIntent contentIntent = PendingIntent.getBroadcast(this, 0, 
            i, 0);
    notification.setLatestEventInfo(this, null, null, contentIntent);
    mNotificationManager.notify(0, notification);

Below is my BroadCast Receiver

public class BReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) 
    {
        Log.d("Test", "########## intent action "+ intent.getAction());
        Toast.makeText(context, "Hi", Toast.LENGTH_LONG).show();

    }

}

The toast will be displayed when you click on the notification icon. It doesnot matter on which screen you are, the toast will be displayed whenever user click notification icon.
