RecyclerView - Part 8, notifyDataSetChanged vs notifyItemChanged

In this advanced Android development tutorial, we delve into the intricacies of handling events in RecyclerView. We explore how adding or deleting items impacts the adapter and whether operations like `notifyDataSetChanged` trigger methods such as `onCreateViewHolder` and `onBindViewHolder`. Through practical demonstrations, we examine the RecyclerView adapter's behavior in response to data changes, emphasizing the importance of efficiently managing view creation and data binding to enhance app performance.

Learn when to use `notifyDataSetChanged` versus `notifyItemChanged` to optimize your RecyclerView's performance. Discover the nuances of updating your dataset, whether you're altering the size or just the content, and understand the significant impact of these changes on your app's UI responsiveness and resource utilization.

This tutorial is perfect for Android developers looking to deepen their understanding of RecyclerView and improve the efficiency of their apps. Join us as we unravel the secrets to fine-tuning the performance of your RecyclerView through effective event handling and data manipulation strategies.

Great example. I am wondering how to Programmatically update the list objects in terms of their status. For example when a user clicks its updates by changing the font colour of the selected text. But if you only want one row to be highlighted a time; would require any existing selected items to have their font colour back to original state. I have spent endless time trying to figure it out but still stumped to why its not changing the font colour back. Have you got any ideas on how this could be achieved?

is now deprecated. any suggestions for modifying one item only?
