Forcing keyboard input on Buttons inside extended Preference

Question

While extending Preference and making your own view by overriding onCreateView(), how can you make widgets inside selectable by keyboard only?

For example, let's say that you have two buttons in your preference, upon pressing DPAD_DOWN, for 4 consecutive times, you'd like PreferenceActivity to behave like:
1.) select your preference (from the one above it)
2.) select only first button
3.) select only second button
4.) select next preference in PreferenceActivity

So, is this possible in some simpler way then to hack ListView inside PreferenceActivity or creating PreferenceActivity from scratch?

Thanks for your replies...
