I have enabled two options in my gradle file.
buildFeatures {
viewBinding = true
dataBinding = true
}
I checked the connections in the XML file.

I checked the data I fetched in my adapter class.
class CountryAdapter(val countryList:ArrayList<Country>): RecyclerView.Adapter<CountryAdapter.CountryViewHolder>(),CountryClickListener {
private lateinit var binding : ItemCountryBinding
class CountryViewHolder(var view:ItemCountryBinding) :RecyclerView.ViewHolder(view.root) {
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): CountryViewHolder {
val inflater = LayoutInflater.from(parent.context)
val binding = ItemCountryBinding.inflate(inflater, parent, false)
return CountryViewHolder(binding)
}
override fun getItemCount(): Int {
return countryList.size
}
override fun onBindViewHolder(holder: CountryViewHolder, position: Int) {
holder.view.country=countryList[position]
holder.view.listener=this
}
fun updateCountryList(newCountryList:List<Country>){
countryList.clear()
countryList.addAll(newCountryList)
notifyDataSetChanged()
}
override fun onCountryClicked(v: View) {
val uuid=binding.countryUuidText.text.toString().toInt()
val action=FeedFragmentDirections.actionFeedFragmentToCountryFragment(uuid)
Navigation.findNavController(v).navigate(action)
}
}
Could you please help me? I couldn't find a solution even though I checked the connections in my XML file, verified the data in my adapter class.
