Answer 1

set ViewPager.setOnPageChangeListener on your viewpager.

Some thing like this-

myViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
            @Override
            public void onPageScrolled(int i, float v, int i2) {

            }

            @Override
            public void onPageSelected(int i) {
              // here you will get the position of selected page
            }

            @Override
            public void onPageScrollStateChanged(int i) {

            }
        });

Answer 2

try like this

ViewPager.getCurrentItem();

or

pageListener = new PageListener();
ViewPager.setOnPageChangeListener(pageListener);

you have to put a page change listener for your viewPager. There is no method on viewPager to get the current page.

private int currentPage;

    private static class PageListener extends SimpleOnPageChangeListener{
            public void onPageSelected(int position) {
                Log.i(TAG, "page selected " + position);
                   currentPage = position;
        }
    }
