Listing large amount of data in listview

Question

I want to three things :

1.Want to show 50000 contacts from db 2.Fast scroller implementation 3.Filter implementation (Edittext)

Currently what i'm doing is :

I Listed contacts in list view by pulling data in worker thread(using aynctask). But in single query itself I'm pulling 50000 contacts. That takes some time and sometimes facing Out-of-memory exception.
I used list-view indexer for fast scroller
using Gauva library for filtering

Please suggest some efficient way to achieve this. Anyway user is not going to see 10000 immediately but i need to implement fast scroller that why pulling all data

first for 50000 list use pagination that fetch 50 record at a time. and use Recyclerview not listview. and for filter use default arrylist method, there is no need for any library — Divyesh Patel, Apr 22 '17 at 08:04

You may need to increase the list size dynamically...Refer the below answers
