Synchronizing two ViewPagers using OnPageChangeListener

Question

I\'m trying to synchronize two ViewPagers, as apparently have quite a lot of people before me, and I\'ve got as far as this:

private ViewPager m         


        

Answer 1

All the Answers are approximately currect in some situation. Here I am giving one more answer which will use to slide both the ViewPagers simultaneously whether there size is same or not:

viewPagerBanner.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
    private int scrollState = ViewPager.SCROLL_STATE_IDLE;
    // Indicates that the pager is in an idle, settled state. 
    // The current page is fully in view and no animation is in progress.

    @Override
    public void onPageScrolled(int position, float positionOffset, 
                               int positionOffsetPixels) {
        if (scrollState == ViewPager.SCROLL_STATE_IDLE) {
            return;
        }
        viewPagerTitle.scrollTo(viewPagerBanner.getScrollX()*
                                viewPagerTitle.getWidth()/
                                viewPagerBanner.getWidth(), 0);
        // We are not interested in Y axis position
    }

    @Override
    public void onPageSelected(int position) {}

    @Override
    public void onPageScrollStateChanged(int state) {
        scrollState = state;
        if (state == ViewPager.SCROLL_STATE_IDLE) {
            viewPagerTitle.setCurrentItem(viewPagerBanner.getCurrentItem(), false);
        }
    }
});
