Android : how to speed up the forward/rewind process when button pressed continuously

I want to increase the forward/rewind speed if the button is pressed continuously.

I created my customized media controller from here.

What would be the good way to speed up the forward/rewind process?

I got some idea form here. But couldn't implement it.The answer posted there use setOnTouchListener and OnLongClickListener and I've already used OnClickListener for the buttons. Other solutions rather than using it would be appreciated.
