First, make suer you have got the titleStrip when createView:

titleStrip = (PagerTabStrip) pagerView.findViewById(R.id.pager_title_strip);

then, you can add OnPageChangeListener to ViewPager, you can do anything you want in onPageSelected method:

mPager.setOnPageChangeListener(new OnPageChangeListener() {

    @Override
    public void onPageSelected(int position) {
        switch (position) {
        case 0:
            titleStrip.setBackgroundColor(Color.BLUE);
            break;

        case 1:
            titleStrip.setBackgroundColor(Color.GRAY);
            break;
        }
    }

    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
    }

    @Override
    public void onPageScrollStateChanged(int state) {
    }
});
