Potentially useful additions

OnSliderStateChangeListener

It would be nice to include the page positions like so:

public interface OnSliderStateChangeListener {
    void onStateChanged(View page,@SlidingContainer.SliderState int state, int position);
    void onPageChanged(View page,@SlidingContainer.SliderState int state, int position);
}

ExpandablePager

You can call setCurrentItem(...) but there should be a getCurrentItem() as well.

ExpandablePagerAdapter

It would be nice if you could also extend FragmentPagerAdapter. I'd like to use fragments instead of views for this.
