I want to use an arrayadapter in listview

My advice: don’t use listview, only recyclerview

why ?

Because RecyclerView is much better replacement for listview

Exactly

🤗 🤔 🤔 I'll give a chance to recyclerview 😄

of course, in some cases ListView can be the only option (you use some legacy code, or legacy third party dependency, or cannot use support library dependencies), but for all other cases just use RecyclerView

If you still want to use listview, i found this: http://scottmmjackson.com/learning-kotlin-simple-listview-adapter/

Ok now Im going to change listview to recyclerview
