both show 'Type mismatch: inferred type is CategoryQuran but MainAdapter.onSelectData! was expected'
Can you guys help me? please
Ok so the problem is i am have to add OnSelectData in my Class, in my case what i have to do is add MainAdaper.OnSelectData
so Before it like :
class CategoryQuran : AppCompatActivity() {
and after it like :
class CategoryQuran : AppCompatActivity(), MainAdapter.OnSelectData {
thats my fault, im too rush when i coding it

I've tried reading Android Studio's official documentation, but it cannot solve my specific problem.
in your class MyViewHolder you have method called binding and you need also to implement it and add paramter
shoud be
class MyViewHolder(private val binding: CellCardsBinding): RecyclerView.ViewHolder(binding.root ) {
fun bind(data:MyObject) {
binding.yourView=data.title ...
}
}
in onBindViewHolder
..
holder.bind(myObject)
After switching from removing kotlin_extensions and switching to view binding, I received a "Unresolved reference: myViewHolder" in my onBindViewHolder method
Well, your onBindViewHolder method is passing a variable called holder and you're trying to use a variable called myViewHolder, so that seems like a problem.
// --------------------this-----v
override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
val myObject = list[position]
// v--- doesn't match this
myViewHolder.bind(myObject)
and when I replace "myViewHolder" with "holder", it then gives me a "Unresolved reference: bind". How do I resolve this.
Your MyViewHolder class has a method called binding that takes no arguments. There is no bind method that takes a "myObject".
class MyViewHolder(val binding: CellCardsBinding): RecyclerView.ViewHolder(binding.root ) {
fun binding() {
}
}
Edit
You should pass an instance of the data class
class MyViewHolder(val binding: CellCardsBinding): RecyclerView.ViewHolder(binding.root ) {
fun bind(object: MyObject) {
// Set variables on binding
}
}
Then pass an instance from your list via onBindViewHolder:
override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
val myObject = list[position]
holder.bind(myObject)
Please check this blog post for more.
I got my answer.
class MyAdapter(private val context: Context, private val mHelper : TaskDbHelper) : RecyclerView.Adapter<MyAdapter.MyViewHolder>(),
SwipeAndDragHelper.ActionCompletionContract {
class MyViewHolder(val binding: CellCardsBinding): RecyclerView.ViewHolder(binding.root ) {
private val titleView: TextView = itemView.findViewById<View>(R.id.title) as TextView
val textView: TextView = itemView.findViewById<View>(R.id.text) as TextView
private val dateTextView: TextView = itemView.findViewById<View>(R.id.date) as TextView
fun binding (myObject: MyObject) {
titleView.text = myObject.title
textView.text = myObject.text
dateTextView.text = myObject.date
}
}
I simply initialised the view I wanted to reference in my layout and called them in the binding() function.
Open PodcastActivity.kt and add the following lines to the top of the class. This is the question
this is the code I am adding

// 3
val searchManager = getSystemService(Context.SEARCH_SERVICE)

// 4
searchView.setSearchableInfo(
searchManager.getSearchableInfo(componentName)
)
return true

A very newbie programmer here and not a good English typer. Im trying to create a checker for purchase that already made previous using the PurchaseHistoryResponseListener. And When a checker found something, it will add to a list and then feed the recyclerview_MYBook with that data. The issue is that when launching the app, the data is flow through the recyclerview_MYBook perfectly, but when moving to different activity and going back to the previous activity through a different method (button click) the data on the recyclerview_MYBook doesn't show up, only through a conventional back button, the data on the recyclerview show up.

You have to specify the interface to help Kotlin compiler:
#SuppressLint("DefaultLocale")
val myTimeListener = TimePickerDialog.OnTimeSetListener { view, hourOfDay, minute1 ->
if (view.isShown()) {
myCalender.set(Calendar.HOUR_OF_DAY, hourOfDay)
myCalender.set(Calendar.MINUTE, minute1)
editText!!.setText(String.format(String.format("%s:%s", hourOfDay.toString(), minute1.toString())))
}
}
