I have a fragment with RecyclerAdapter inside it. I want to initialize the adapter in the onCreateView
method but it throws the error of "Type mismatch. Required : Context , Found : FragmentActivity"
in this statement
I have no idea why the first one showed this error and the second one did not contains compile time error.
Error shown
recyclerView!!.adapter = RestaurantMenuAdapter(activity)
No Error shown
recyclerView!!.layoutManager = LinearLayoutManager(activity)
Fragment.kt
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?): View? {
// Inflate the layout for this fragment
val view = inflater.inflate(R.layout.fragment_restaurant_menu, container, false)
recyclerView = view.findViewById(R.id.restaurant_container)
recyclerView!!.adapter = RestaurantMenuAdapter(activity)
recyclerView!!.layoutManager = LinearLayoutManager(activity)
RecyclerAdapter.kt
class RestaurantMenuAdapter (val context : Context) : RecyclerView.Adapter<RecyclerView.ViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerView.ViewHolder {
val inflater = parent.context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
return object : RecyclerView.ViewHolder(inflater.inflate(R.layout.item_menu1, parent, false)) {
}
}
override fun onBindViewHolder(holder: RecyclerView.ViewHolder, position: Int) {
}
override fun getItemCount(): Int {
return 10
}
}
Change this from :
recyclerView!!.adapter = RestaurantMenuAdapter(activity)
To :
recyclerView!!.adapter = RestaurantMenuAdapter(activity.applicationContext)
