Updating Button background for a brief time in Android (higlight it)

Question

Hi,

I have a button and I want to highlight it for a brief time. For e.g. it's a red button and it should be orange for a second and then turn red again.

My code for this looks like the following:

button.setBackgroundResource(R.color.orange);    //highlight value
button.invalidate();
            try {
                Thread.sleep(3000);
            } catch (InterruptedException e1) {
            } 
button.setBackgroundResource(R.color.red);   //old value
button.invalidate();

This doesn't work. The current thread pauses for 3 seconds, but the background image is not changed before. In fact it only changes afterwards to the "old value".

How can i build this highlight feature?

You could instead try something like this answer to add the highlight. You could play around with a few of the different PorterDuff modes and see which results you like.
