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) {

            }
        });
