Android hides scroll bars unless the window is actively being scrolled. This makes it hard to tell if a window can be scrolled without actually trying it. Is there a way to force Android to always show scroll bars when there is something to scroll?

I have a Thunderbolt running Android 2.2 (Froyo).

When an activity that can be scrolled opened, the scroll bar should show for a few seconds before fading, therefore you can will know that the page can be scrolled. If you missed the subtle hint, then just slightly swipe the screen to display the scroll bar.

IMO, it wouldn't be a good idea to always display the scroll bar, as the scrollbar is in the content area and may obscure whatever is in the screen.

I know that they show briefly, but I want them to always show. I don't mind if the content areas are permanently narrower by a few pixels to make room for the always-visible scrollbar. –  Richard Hansen Sep 11 '11 at 16:49

As @Lie says, this simply isn't possible as a setting. You could possibly take the Android source code and edit it and create a ROM of your own with this change, but as a user, this isn't possible. –  Jaxidian Sep 23 '11 at 19:25
    
Note that it seems that the scroll bar only flashes if android:scrollbarAlwaysDrawVerticalTrack="true" - at least in my experience on ScrollViews w/ 3.0 –  Peter Ajtai Nov 17 '11 at 19:52

The scrollbar visibility and fadeout effect can only be defined on the application itself at a programming level, there's no general option to control this.

Developers tend to follow the best practices, regarding small screen devices, since the space is limited. The general concept here is to have scrollbars hidden while not in use, since they appear over the content being presented. This is due to the limited space available, that portable devices tend to have.

Don't know if you ever noticed that scrollbars on smart-phones and tablets appear over the contents, and don't have a designated space as we see on desktop computers:

Scrollbars over the content presented

It's all about the UI, and unfortunately for you, it's the general concept that AFAIK isn't going to change.
