My button on clicked is not working in Kotlin Android Studio

I am facing a problem which is my button ID is well-configured and in my main activity, I am calling the button using the correct ID too, but after I run the project on the emulator, the button is not working after I clicked on it for multiple times.
Can anyone help me to solve the problem?

btnStart.setOnClickListener {
Toast.makeText(this#MainActivity, "You clicked me.", Toast.LENGTH_SHORT).show()
}
}
}

findViewById is an old method.
i would recommend you to use with ViewBinding.
click here to documentation

You can use viewBinding
add line to build.gradle
buildFeatures{
viewBinding true
}
and update your activity like this
class MainActivity : AppCompatActivity() {
private lateinit var binding: ActivityMainBinding
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
binding.btnStart.setOnClickListener{
Toast.makeText(this#MainActivity, "You clicked me.", Toast.LENGTH_SHORT).show()
}
}

Issue with implementing View Binding in Android

I am trying to implement view binding to one of my activity. The issue is I am not able to access the views and it shows unresolved reference.
Now when I am using tools:viewBindingIgnore="true"
then there are no issues with the views and I am able to access them but then I am getting unresolved symbol for the activity class.

Two-Way Data Binding with a LiveData object of modal class

I'm trying to create a Two-Way Data binding connection with a LiveData object of a modal class. But when I tries to read the values of user it turns out to be null. Here is my code -

val viewModal: MainActivityViewModal = ViewModelProvider(
this,
MainActivityViewModalFactory()
).get(MainActivityViewModal::class.java)
val binding = DataBindingUtil.setContentView<ActivityMainBinding>(
this,
R.layout.activity_main
).apply {
this.lifecycleOwner = this#MainActivity
this.viewModal = viewModal
}
}}
Here is the Layout file -

Here is the ViewModal
class MainActivityViewModal : ViewModel() {
var user = MutableLiveData<User>()
fun login() {

And here is the Modal Class
class User() {
var userName: String = ""
var password: String = ""
override fun toString(): String {
return "User(userName='$userName', password='$password')"
}}
Please tell me any solution or a good way around to this problem

In the MainActivityViewModal define user as just User type rather as MutableLiveData.

How to fix a Recyclerview that doesn't scroll smoothly?

I am using a RecyclerView with LinearLayoutManager to fetch Data that I get from my API using Retrofit.
The problem is whenever I try to scroll down it goes to the first position.
Some answers on Github & Here, suggested decreasing the image' resolution and avoid using focusable objects but none of these solutions worked for me.
This is my RecyclerView declaration

This is my part of Code where I get the data from DB and adapt it into the RV
fun prepareRecyclerView(v : View, id : String){
val layout = LinearLayoutManager(v.context)
layout.orientation = LinearLayoutManager.VERTICAL
val adapter = v.findViewById<RecyclerView>(R.id.recyler_view_voiture_occasion)
adapter.layoutManager = layout
val annonceAdapter = OccasionCarsAdapter(v.context,annonceList )
adapter.adapter = annonceAdapter
//initLineaire(v , R.id.recyler_view_voiture_occasion, LinearLayoutManager.VERTICAL ,annonceAdapter as RecyclerView.Adapter<RecyclerView.ViewHolder>)
}
fun getAnnonceList(id: String, maView: View, filters: VehiculeRechFilters?){
val service = prepareService()
val requestCall = service.GetOccasionAnnouncement(id,
filters!!.minPrix, filters.maxPrix, filters.minAnnee,
filters.minAnnee, filters.maxKm, filters.codeVersion)
requestCall.enqueue(object : Callback<List<VehiculeOccasion>> {
override fun onFailure(call: Call<List<VehiculeOccasion>>, t: Throwable) {
Log.e("Call response" , "Can't get the data" , t.cause)
}
override fun onResponse(call: Call<List<VehiculeOccasion>>, response: Response<List<VehiculeOccasion>>) {
if(response.isSuccessful){
Toast.makeText(this#CustomOccasionFragment.context,response.body().toString(), Toast.LENGTH_LONG).show()
for (e in response.body()!!){
annonceList.add(e)
}
prepareRecyclerView(maView!! ,idUser)
}
else {
Log.i("response assert" , "couldn't get the data correctly")
}
}
})
}
