With a little Trick, the behavior can be achieved with the ScrollView-Behavior inside the ViewPager. If you only want to restrict the area of the most left fragment, you can restrict the scroll limits of the ScrollView.

In your case: in the onPageChangeListener of the ViewPager do something like that:

@Override
public void onPageScrollStateChanged(int arg0) {
    restrictLeftScroll();
}

@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
    restrictLeftScroll();
}

@Override
public void onPageSelected(int arg0) {

}

private void restrictLeftScroll() {

    if (display != null) {

        /* get display size */
        Point size = new Point();
        display.getSize(size);

        /* get desired Width of left fragment */
        int fragmentWidth = getResources().getDimensionPixelSize(R.dimen.category_fragment_width);

        if (mViewPager.getScrollX() < size.x - fragmentWidth) {
            mViewPager.scrollTo(size.x - fragmentWidth, mViewPager.getScrollY());
        }
    }
}

This piece of code worked for me without problems. ;)
