Issues to be fixed:

Do not know why it would not scroll sometimes if setHorizontallyScrolling is called in constructor;

The scrolling is not smooth enough. Maybe it's because of the single thread model of Android UI;

Tested on:

Windows XP

Android SDK 1.0 rc2

Android Emulator 1.0

Android Debug Bridge version 1.0.20
