Hi sir,i have got an error of "unresolved reference setOnClickListner" and "unesolved reference onClickListner"

#1

I have searched a lot in stackoverflows but could not resolve the errors.Please help me to rectify these errors

#2

Have you imported the view correctly ? You should import button correctly in order to use it

#3

okay ,this problem is solved.my next ques is why are we converting etvar1 to string before converting it to int,why cant we directly convert it into int (why this (etvar1.text.toStrong().toInt() ->>etvar1.text.toInt()))

#4

########its toString not toStrong

#5

Can you please tell me why are we passing this as a parameter here:…rvTodos.layoutManager=LinearLayoutManager(this)

#6

Because the layout manager needs the context/reference of window/ui screen
