Why init block not executing when a class inherited another open class Android Kotlin?

Question

I have BaseClass like this :

open class BaseClass(private var context: Context) {
      init{
         println("BaseClass init called")
      }
}

And ChildClass like this:

class ChildClass(private var context: Context) : BaseClass(context) { 
      init{
         println("ChildClass init called")
      }
}

So call it like this:

context?.let { ChildClass(it) }

But not called any init functions.

is it spelling error? your class name is ChildClass, but you create ChildeClsss, i test your code and everything was okey — hamid_c, Jan 13 '20 at 08:43

println print the log in Console. To print log in logcat, you have to use Log. like:

init{
    //println("BaseClass init called")
    Log.v("TAG", "BaseClass init called")
}

yes, Tnx i think i must keep state in fragment because context is null – reza_khalafi Jan 13 '20 at 09:00
Now how to keep context in fragment kotlin – reza_khalafi Jan 13 '20 at 09:07
That is different things. You should create another post with your fragment code from where you call this. – Md. Asaduzzaman Jan 13 '20 at 09:18

I think your context is null in this line:

context?.let { ChildClass(it) }
