hello guys I am using a gson api with a Recyclerview and I got this error with the adapter and it says that the
expression 'myAdapter' of type 'myAdapter' cannot be invoked as a function. the function 'invoked' is not found
and when I run the code without the data it gives me this error:
lateinit property myAdapter has not been initialized
my activities and classes
private val datalist: MutableList<Sura> = mutableListOf()
private lateinit var myAdapter: MyAdapter
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_quran_a_p_i)
myAdapter = myAdapter(datalist) // here is the error
apiQuranRecyclerView.layoutManager = LinearLayoutManager(this)
apiQuranRecyclerView.addItemDecoration(DividerItemDecoration(this, OrientationHelper.VERTICAL))
apiQuranRecyclerView.adapter = myAdapter
AndroidNetworking.initialize(this)
AndroidNetworking.get("http://api.islamhouse.com/v1/mykey/quran/get-category/462298/ar/json/")
.build()
.getAsObject(Surasnames::class.java, object : ParsedRequestListener<Surasnames>{
override fun onResponse(response: Surasnames) {
datalist.addAll(response.suras)
myAdapter.notifyDataSetChanged()
}
override fun onError(anError: ANError?) {
}
})
}
my Adapter
class MyAdapter (private val datalist: MutableList<Sura>): RecyclerView.Adapter<myHolder>() {
private lateinit var context: Context
override fun onCreateViewHolder(parent: ViewGroup, p1: Int): myHolder {
context = parent.context
return myHolder(LayoutInflater.from(context).inflate(R.layout.api_quran_view, parent, false))
}
override fun getItemCount(): Int = datalist.size
override fun onBindViewHolder(holder: myHolder, position: Int) {
val data = datalist[position]
val apisuraname = holder.itemView.apiSuraNames
val surasnames = "${data.id} ${data.title}"
apisuraname.text = surasnames
holder.itemView.setOnClickListener {
Toast.makeText(context, surasnames, Toast.LENGTH_SHORT).show()
}
}
my Holder
class myHolder(itemView: View) : RecyclerView.ViewHolder(itemView) { }
my Models
data class Sura(
@SerializedName("add_date")
val addDate: Int,
@SerializedName("api_url")
val apiUrl: String,
@SerializedName("id")
val id: Int,
@SerializedName("title")
val title: String,

You need to call the constructor. Change the line
myAdapter = myAdapter(datalist)
to
myAdapter = MyAdapter(datalist)
