    private int mLastPagePosition = -1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...

        mViewPager = (ViewPager) findViewById(R.id.viewpager);
        mViewPager.addOnPageChangeListener(this);

        ...
    }

    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
        if (mLastPagePosition != position) {
            // the selected page is changed
            mLastPagePosition = position;
        }
    }

    @Override
    public void onPageSelected(int position) {
        if (mLastPagePosition != position) {
            // the selected page is changed
            mLastPagePosition = position;
        }
    }

    @Override
    public void onPageScrollStateChanged(int state) {
    }

}
