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
