Try this, I also never tried so let me know if it worked or not.

 scroll.setOnTouchListener(new OnTouchListener() {

            public boolean onTouch(View v, MotionEvent event) {

                if (event.getAction() == MotionEvent.ACTION_UP) {

                   //show footer
                }
else  if (event.getAction() == MotionEvent.ACTION_DOWN) {

                   //hide footer
                }    
                return false;
            }
    });
