        final Handler handler = new Handler(); 
        Timer t = new Timer(); 
        t.schedule(new TimerTask() { 
                public void run() { 
                        handler.post(new Runnable() { 
                                public void run() { 
                                 my_button.setBackgroundResource(R.drawable.defaultcard); 
                                } 
                        }); 
                } 
        }, 2000); 
    }
