ViewPager viewPager = findViewById(R.id.view_pager); PagerAdapter adapter = new PagerAdapter(getSupportFragmentManager()); viewPager.setAdapter(adapter);
viewPager.setPageTransformer(true, new DepthPageTransformer());
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() { @Override public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { // TODO: respond to scrolling } @Override public void onPageSelected(int position) { // TODO: update UI for new page } @Override public void onPageScrollStateChanged(int state) { // TODO: respond to scroll state changes } });This code adds a listener to the ViewPager that responds to page scrolling and selection events.
