How to pause / sleep thread or process in Android?

by

I want to make a pause between two lines of code, Let me explain a bit:

-> the user clicks a button (a card in fact) and I show it by changing the background of this button: 

thisbutton.setBackgroundResource(R.drawable.icon);

-> after let’s say 1 second, I need to go back to the previous state of the button by changing back its background: 

thisbutton.setBackgroundResource(R.drawable.defaultcard);

-> I’ve tried to pause the thread between these two lines of code with:

try {
    Thread.sleep(1000);
} catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

However, this does not work. Maybe it’s the process and not the Thread that I need to pause?

I’ve also tried (but it doesn’t work):

new Reminder(5);

With this:

public class Reminder {

Timer timer;

        public Reminder(int seconds) {
            timer = new Timer();
            timer.schedule(new RemindTask(), seconds*1000);
        }

        class RemindTask extends TimerTask {
            public void run() {
                System.out.format("Time's up!%n");
                timer.cancel(); //Terminate the timer thread
            }
        }  
    }

How can I pause/sleep the thread or process?
