Answer 1

Here is the method which is used by FragmentPagerAdapter to create the Fragment's tag name:

private static String makeFragmentName(int viewId, long id) {
    return "android:switcher:" + viewId + ":" + id;
}

viewId is the id of the ViewPager.
id is the position of the fragment inside the ViewPager.

Example:

String fragmentTag = makeFragmentName(myViewPager.getId(), 2);
Fragment fragment = getSupportFragmentManager().findFragmentByTag(fragmentTag);
