Call another thread inside the "on click" callback, like this:

Thread t = new Thread(new Runnable() {  
    public void run() {  
        // your code  
    }  
});  
t.start();

Answer 4

You could use "concurrent" package from Java 5:

java.util.concurrent package summary

and, in particular, a thread pool. This would be more robust, since if you couldn't handle thread termination correctly or will occasionally leave it alive you could have a resource leak.
