Android: notifyDataSetChanged(); not working

Question

I have a database in a server and from a Tablet I take some values from one table in the database. I load this information correctly into a list but I would like to know why

Answer 1

If everything you set fine and still not working then your list... Is it Mutablekind of the List or not...!

private val demoList: MutableList = mutableListOf()

once you define your list like above mutable manner then you can get the method

.add
.addAll
.remove

etc...

else if you have created normal list then that will not work as notifyDataSetChanged
