Custom Page Available for ViewPager

Question

The Android Music app has a nice implementation of ViewPager . When moving pages, it has a vertical divider consisting of two white (I think) lines and transparency between them. What should be the attractiveness of the page to get this look?

 // Here, 10 dip margin and an XML resource called viewpager_margin... viewPager.setPageMargin(getResources().getDimensionPixelSize(R.dimen.viewpager_page_margin)); viewPager.setPageMarginDrawable(R.drawable.viewpager_margin); // XML = ? 

Answer 1

See my comment above. The proposed solution works!
