In particular at this lines of code,cause I tried debbugging as you can see here , only to find out that I get null so I guess I'm not getting data from the intent (more in depth from
putExtra("listaRistoranti", responseR.ristoranti)
this line of code)
val r = intent.getParcelableArrayListExtra<Restaurant>("listaRistoranti") as ArrayList<Restaurant>?
val bundleR = Bundle()
bundleR.putParcelableArrayList("listaRistoranti", r)
can somebody help me and also explain what I did wrong

How to set the visibility GONE after the download was successful, and visibility still VISIBLE if download was unsuccessful?

I am making a studymaterial app, where i want to add a functionality where - when a user download a particular chapter from recyclerview and after the successful download of that item the Download button visivity should make GONE of that item at that time.
I have implemented a method to do thisd but it only works when user finish the activity and come back again on that activity then the download button automatic not showing, but i want to implement at that point of time when user download something.
Here is my DownloadHandler.kt class

Maybe you want to use LiveData to handle realtime update UI for your case. After download thread run completed, let observer call update item in recyclerview.
Hope it help!

second viewModel unable to construct

I have a problem building a second viewModel for my app.
In my project, the first viewModel observes a list of Contact, while the second viewModel observes a single contact.
Both viewModels are really similar, but the first builds, while the second cannot construct

Thank you for your help !

here you are passing ContactsViewModel::class.java. You have to pass ContactViewModel::class.java
class Factory(val app: Application) : ViewModelProvider.Factory {
override fun <T : ViewModel?> create(modelClass: Class<T>): T {
if (modelClass.isAssignableFrom(ContactViewModel::class.java)) {
#Suppress("UNCHECKED_CAST")
return ContactViewModel(app) as T
}
throw IllegalArgumentException("Unable to construct viewmodel")
}
}
