Such a question, how to make such a search, as in a notebook? Means clicking on the letters on the right and moving to the corresponding letter on the screen? How to do it right? Interested in UI and the technical part. I understand that you can use RecyclerView for the column on the right (of the alphabet), add OnClickListener to it. Contacts can also be placed in RecyclerView or ExpandableListView and when clicked to the right, scroll to a specific position of the contacts.

    Perhaps ready-made examples will help you: AlphabetScroll and Alphabet RecyclerView / Maybe these ready-made libraries will be enough for you - pavlofff

  • If you do your implementation, write the answer, like there if possible. - pavlofff
  • If you do your implementation, look at the ready-made implementations first, so as not to write from scratch :). - Rostislav Dugin
  • too broad a question, in a notebook different solutions in different versions of Android not to mention the multitude of devices having their shells on top, HTC, LG, MeizU, Huawei, Zeta, Asus and damn almost everyone has their own solutions, so you need. Since the native solution looks different, I can give an answer only to be afraid of wasting time in vain. If you mean Google Contacts, then a friend case, what is different on your screen, I had such a thing on 4.03 LG. I’ll be happy to show you how to do it - Shwarz Andrei
