java - Calling activity method in custom adapter class -

-

so trying refresh recyclerview in activity problem doesn't casting or way calling it.

any ideas?

from crashlog, appear passing applicationcontext recyclerview. instead, need pass activity context, , ensure activity implements userrview interface.

a cleaner way pass context , pass userrview adapter, not have cast context userrview, , can continue pass application context if prefer.

edit: replace code

adapter = new customradapter(list, getbasecontext());

with

adapter = new customradapter(list, this);
