How to use SharedPreferences in RecyclerView.Adapter in Kotlin?

This is need for DarkMode

I need to load my colorMode var from SharedPreferences in RecyclerView.Adapter, but IDE marks "this" or "application" like an error

where can I insert those code without any errors

    val preferences = *this*.getSharedPreferences("MyPreferences", Context.MODE_PRIVATE)
    val editor = preferences.edit()
    var colorMode = false
    colorMode = preferences.getBoolean("ThemeMode", false)

this refers to the adapter and not the the context.

You should call getSharedPreferences() on the context of your app.

If this code is inside the ViewHolder, use this:

val preferences = view.getContext().getSharedPreferences("MyPreferences", Context.MODE_PRIVATE)

Best
