Answer 1

use Communication with Handlers ,

1. execute your thread
2. into run() : you should send a message to the Handler which will update the progressBar (Horizontal of course ) : handler.sendMessage(handler.obtainMessage());

3. in your Activity , you should override the method handleMessage(Message msg ) : like this

   handler = new Handler(){
     @override
     public void handleMessage(Message msg ) 
     {
       //here you write the code which will update your progressBar 
     }
   };
