How to set button click effect in Android?

Question

In Android, when I set background image to Button, I can not see any effect on button.

I need some effect on button so user can recognize that button is clicked.

Making a minor addition to Andràs answer:

You can use postDelayed to make the color filter last for a small period of time to make it more noticeable:

        @Override
        public boolean onTouch(final View v, MotionEvent event) {
            switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN: {
                    v.getBackground().setColorFilter(color, PorterDuff.Mode.SRC_ATOP);
                    v.invalidate();
                    break;
                }
                case MotionEvent.ACTION_UP: {
                    v.postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            v.getBackground().clearColorFilter();
                            v.invalidate();
                        }
                    }, 100L);
                    break;
                }
            }
            return false;
        }

You can change the value of the delay 100L to suit your needs.
