ListView itself is scrollable.

Why is the scroll bar always visible?

By default, a scroll bar will appear when the content is too long. Page authors can override this in a number of ways, for example: overflow-y: hidden => cut off content that is too long. overflow-y: scroll => always show a scroll bar even when it's not needed.

Sure, it is possible. Try View.setScrollbarFadingEnabled.
