Listing 9.10 code, Page: 185 (Printing version)
private inner class CrimeHolder(view: View)
: RecyclerView.ViewHolder(view) {
val titleTextView: TextView = itemView.findViewById(R.id.crime_title)
val dateTextView: TextView = itemView.findViewById(R.id.crime_date)
}
I know itemView is a property of RecyclerView.ViewHolder, is inherited to CrimeHolder and
itemView has the reference to the View of item.
So above codes is right. But if I change like this (using view instead of itemView),
private inner class CrimeHolder(view: View)
: RecyclerView.ViewHolder(view) {
val titleTextView: TextView = view.findViewById(R.id.crime_title)
val dateTextView: TextView = view.findViewById(R.id.crime_date)
}
What’s the difference?
I think this code is easier to understand,
because many people may be wondering “What is itemView?”, if they didn’t try to find RecyclerView.ViewHolder in Kotlin androidx API Doc.
