Sort recyclerview according to few keywords in java

Question

I want to sort my recyclerview items like, when a particular keyword is searched, the matching named items should be on top and others items should be on bottom.

I'm working in android studio (Java).

Answer 1

you need to generate some numeric (sortable) score by which to sort your item list and maybe add it as a property of each item. Once the user types the search text you will calculate and update this value for each item. If you want to sort by string similarity I recommend the Levenstein distance . Read about it here with its java implementation. Then you need to implement thecomparable interface on your Item objects so you can sort them by that distance
