How to show and hide actionbar for fragments using viewpager

Question

I have fragment A, B, C, D inside a viewpager. I want to hide the actionbar in fragment A and show the actionbar for the rest of the fragments.

Any Ideas? Thanks.

Edit: Tried the following and still had the actionbar show up in all the fragments.

@Override 
public void onPageSelected(int position) {
if (position == 0) {
  mActionBar.hide();
} else {
  mActionBar.show();
}
}

Pretty much when you open the activity with the viewpager I am want Fragment A to show up with no actionbar but when i swipe to view the other fragments I want the actionbar to be shown.

In Fragments you want to show the Action Bar :

@Override
public void onResume() {
    super.onResume();
    actionBar.show();
}

In Fragments you dont want to show the Action Bar :

@Override
public void onResume() {
    super.onResume();
    actionBar.hide();
}

For a ViewPager :

viewPager.setOnPageChangeListener(new OnPageChangeListener() {

        @Override
        public void onPageSelected(int selectedPage) {
        // Check the selectedPage here and then show and 
        // hide the actionBar accordingly. 

        }

        @Override
        public void onPageScrolled(int arg0, float arg1, int arg2) {

        }

        @Override
        public void onPageScrollStateChanged(int arg0) {

        }
    });
