A1m :
Can I use ViewBindings to replace findViewById
in this typical RecyclerView.Adapter
initialization code? I can't set a binding
val in the object as the ViewHolders are different per cell.
class CardListAdapter(private val cards: LiveData<List<Card>>) : RecyclerView.Adapter<CardListAdapter.CardViewHolder>() {
class CardViewHolder(val cardView: View) : RecyclerView.ViewHolder(cardView)
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): CardViewHolder {
val binding = CardBinding.inflate(LayoutInflater.from(parent.context), parent, false)
return CardViewHolder(binding.root)
}
override fun onBindViewHolder(holder: CardViewHolder, position: Int) {
val title = holder.cardView.findViewById<TextView>(R.id.title)
val description = holder.cardView.findViewById<TextView>(R.id.description)
val value = holder.cardView.findViewById<TextView>(R.id.value)
// ...
}
A1m :
I found two options:
Use the bind
method on the Binding class
override fun onBindViewHolder(holder: CardViewHolder, position: Int) {
val binding = CardBinding.bind(holder.cardView)
// binding.title ...
Or attach the binding
to the ViewHolder instead of the View
class CardViewHolder(val binding: CardBinding) : RecyclerView.ViewHolder(binding.root)
Then access with:
holder.binding.title
