Parameter specified as non-null is null: method kotlin.jvm.internal.Intrinsics.checkParameterIsNotNull, parameter convertView

Question

I got this error just after converted the adapter code to Kotlin:

java.lang.IllegalArgumentException: Parameter specified as non-null is null: method kotlin.         


        

Answer 1

Make convertView nullable:

convertView: View?

I'm not sure why the line number is wrong, but the stacktrace tells you where to look in the error message.
