How to make button invisible when end of the list is reached in android

Question

I am using HorizontalScrollView to display list of items to user. I want to make two buttons at both ends of list to indicate if there are items remaining on its respective side. So the button must disappear after end of the list is reached on its side. How to invoke this type of behavior in button.

Two options: you can make the button transparent or you can make its height equal to 0dp. — confused_at_times, May 01 '14 at 20:29
