Is it possible to create a Page View from null?

Question

I am implementing a book style reading method and would like to put just a background image and at the time I give the Scroll side came the value on the other side, exactly like a newly opened book.
The question is, is there a way to create a Viewpager from null?,Since in our basic use Viewpager already comes with something created Starting from a view loaded with information,.

The android explains the working here, but as I said comes with values...
I did not put examples because the doubt is not related to coding itself but if there are ways to encode

The example referred to in documentation that’s right: an example.
In it is used only one Fragment that is used on all pages.

What you need to do is:

• create a Fragment for each of the pages that must be presented by Viewpager.
  The first will have only one image, each of the others with the "values" and eventually the last (back cover) also with only one image.

• implement the method getItem() of Fragmentstatepageradapter so that for each of the pages the respective Ragment.

  private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
      public ScreenSlidePagerAdapter(FragmentManager fm) {
          super(fm);
      }
  
      @Override
      public Fragment getItem(int position) {
          switch (position){
              case 0: return new FragmentPage1();
              case 1: return new FragmentPage2();
              case 2: return new FragmentPage3();
              ....
              ....
          }
          throw new IllegalArgumentException();
      }
  
      @Override
      public int getCount() {
          return NUM_PAGES;
      }
  }
