When you start scrollin

Answer 1

You can enable scroll bar fading for your entire app on API level 5 and newer via a custom theme and the fadeScrollbars style attribute by adding this to styles.xml:

Then set the new theme for your application in AndroidManifest.xml:

Just be sure you're not overriding this global theme on individual activities. Earlier Android versions will safely ignore this unknown XML attribute and not fade the scrollbars.
