  A collection of samples to discuss and showcase different architectural tools and patterns for Android apps.

  

I'm studying "Android App Development with Kotlin" by Google at Udacity. In one of the lessons, you are taught how to handle clicking items from a RecyclerView in the fragment, using a callback function, like this: val clickListener: (sleepId: Long) -> Unit) , and from the fragment calling any methods of your ViewModel. Studying this project https://github.com/android/architecture-samples, the pattern used to handle clicks is to send the ViewModel to the ViewHolder and add it to the binding as a variable and make all the XML method calls, like this: android: onClick = "@{viewModel.taskComplete(task)}".Performatively, which of these ways is faster?
