列表视图导航就像在Android联系人视图中一样

Question

I have a really basic question about the android list view element. I have a list view with about 100 elements. To simplify the navigation, I would like to use a 'list view navigation bar' as marked in the image below

I searched for it but I still don't know if this is a standard view or not. I guess not. And if not, how might this smart list view navigation be implemented?
