It seems like problem is somehow related to fact that I'm trying to
tie listener with controls of activity in adapter.
I there any other way to attach listener code to controls in
particular row of listview instead of used by me?

God, grant me the serenity to accept the things I cannot change,
courage to change the things I can,
and wisdom always to tell the difference.
