Show a progress dialog when a thread is running

We can easily show a progress dialog with Async task. But asyn task has its own drawbacks. There can be no ui's and the task can be executed only once.
   Better way is to use a thread for lengthy processing and show a progess dialog in the ui thread. (I struggled quite a bit. My progress dialog would keep on spinning infinitely :-( )

e.g.

//this is your main activity thread handler = new FeedReadHandler(); .... .....
pd = ProgessDialog.show(context,"Loading","Loading the file. please wait..."); Thread background = new Thread(new Runnable(){     

                        @Override
                        public void run() {
                            readFeed(nameUrl);
                            Message msg = handler.obtainMessage();
                            msg.arg1=FEED_LOAD_FINISHED;
                            handler.sendMessage(msg);

                        }

                    });
                    background.start();
                    -..... .....…
