Hi,

    I am having problem with colour change of 2 buttons:

This is a simple code that I tested out on a device:

 button1.setOnClickListener(new OnClickListener(){

                        @Override
                        public void onClick(View v) {
                                // TODO Auto-generated method stub

                                try {
                                        Thread.sleep(15000);
                                        } catch (InterruptedException e) {
                                                // TODO Auto-generated catch 
block
                                                e.printStackTrace();
                                        }
                        }

        });



       button2.setOnClickListener(new OnClickListener(){

                        @Override
                        public void onClick(View v) {
                                // TODO Auto-generated method stub

                                try {
                                        Thread.sleep(15000);

                                } catch (InterruptedException e) {
                                        // TODO Auto-generated catch block
                                        e.printStackTrace();
                                }
                        }

            });

When I click on button1 and (while this is executing) click on button2
and back to button1, both button1 and button2 appear coloured blue.
Why is this happening? The colouring of the 2 buttons should appear
sequentially because button clicking happens on the main thread, is it
not?

(Actually, I posted the same question on an earlier thread too but I
have not been able to figure out why this is happening)

Thank you,
B.Arunkumar
