Create dynamic lists in Android with RecyclerView

The article provides a detailed guide on creating a dynamic RecyclerView.Adapter in Android apps that can display a heterogeneous list of items using different ViewHolders for various backend-controlled viewTypes. It explains how to map backend responses to Kotlin classes and avoid runtime crashes by using a polymorphic JSON adapter with Moshi and Retrofit. The author emphasizes the importance of creating separate UI models for clean code practices and demonstrates how to construct different ViewHolders and a dynamic adapter that overrides the getItemViewType() method. The article also addresses adhering to SOLID principles by employing the Visitor pattern to manage viewType responsibilities, thereby reducing modifications needed in the adapter class when new viewTypes are added. Throughout, it highlights the importance of clean, extensible code and concludes with the potential use of LogRocket for monitoring and improving Android app performance.
