In this article, we’ll walk through a sample scenario: a scrolling list for a maintenance app, listing machine parts: “PartsList”. However, this scenario only affects the strings we use – you can copy this approach for any use case you need. Continue reading “Kotlin & RecyclerView for High Performance Lists in Android”
