Is there an Android official alphabet fast scroll view? If yes, how to use it?
And I find some third party lib like MaterialScrollBar, but I prefer official version if it exists.
Any help is very appreciated.
What a pity, there is no such thing untill now. However, there are some useful classes such as:AlphabetIndexer in case you want to implement yourself from official components like NestedScrollView, RecyclerView

This is one of the implementations that I have the most difficulty in actually finding the best way to solve.
There are a lot of techniques and ways, but the last answers I found did not really seem to me to solve the problem. Another point is that they are usually very old techniques and libraries.
What I want to do is this:
How do I create this ListView with a GridView inside and the screen has infinite height without using ScrollView, so we know that it is not recommended to use ListView within ScrollView.
I am not asking you to develop the code, but rather recommend me the correct architecture that I should use to implement this (ScrollView, ListView, GridView), or memo a library that has new development concepts that can help me.
This question arises because many of the existing responses are too old and have outdated ideas.
I know the question is of a slightly higher level of complexity, but I accept everyone's help.
Thank you very much.
It is very easy to solve this using a RecyclerView.
The documentation is pretty clear and explains all the details necessary for the development of the functionality.
I will leave the necessary documentation links to implement:
RecyclerView
GridLayoutManager
ItemsViewHolder
We know that it is always better to use native components in the development, I recommend, but if you prefer to use a library ready to solve your problem, here are some interesting:
Sticky Headers
recyclerview-stickyheaders
StickyListHeaders
What is the newest and simplest way to do this?
All I want is the ability to drag parent items around and click them to expand to show their child items, with efficient operations if you delete or add.
Is there a library that does this and is simple to use? I tried Googling but everyone keeps saying this and that is outdated or inefficient but offer no alternatives.
Or can I just make one myself somehow? Is ItemTouchHelper what I need for expanding and moving stuff around?
Or is this built in somewhere? I'm using the support library.
I spent a long time in order to find a way to implement such a list. Check out my github project:

If you have any questions: Just ask me ;) Hope I can safe you a lot of time and trouble.
You can try this library. It allows an expandable, draggable and swipeable RecyclerView with many other features.
I hope my question doesn't violate the rules of StackOverFlow. I am writing an android app and want to implement a list view that is expandable. I am aware of expandableLisView and 3rd party libraries of different versions of expandable recycler view such as this or this . Although, I am trying to avoid using libraries and be as native as possible. knowing that recyclerView is more recent and potentially more efficient than listViews, I am afraid that expandableListView gets deprecated at some point in the near future and google comes up with something like that for recycler view.
Just wondering if anyone is aware of such a thing or if expandableListView would be a safe bet to go with. Thanks a lot for your input.
I want to add a header to my list view that will appear when I scroll up and disappear when I scroll down. This functionality is in the Facebook app. Is there any component in the ListView that I can call?
If you are comfortable using 3rd party libraries, here's a great one based on what you want.

Also, I would really suggest you to take a look at Libraries for developers app. https://play.google.com/store/apps/details?id=com.desarrollodroide.repos
Very much useful for us developers! I happen to stumble upon a lot of useful libraries from this app!
I'm tying to accomplish an instagram style scrolling view, only with the actual view being an expandablelistview, i've looked around and couldn't find any examples or hints for implementation other then listview being the view at hand.
any thought or has anyone tried it ?
it comes built in in iOS and i'll be really happy implementing it on an expandableListview
thanks
I've recently developed an open source library that provides pinned headers for the ExpandableListView. You can take a look at https://github.com/diegocarloslima/FloatingGroupExpandableListView.
use 3d party library PinnedHeaderListView
