android - "...cannot be resolved to type" error message; no method suggestions in Eclipse -


ok guys i've got question life of me cannot figured out. i'm using eclipse, , i've got android adt pluging installed, program configured android sdk path, , sdk parts downloaded (google api's, sdk platforms, system images). here problem: whenever go access method object, eclipse gives no method "suggestions" does. i'm not explaining best, i've attached screenshot kind of illustrates issue. 

public class startingpoint extends activity {  int counter; button add; button sub; textview display;          //putting add.whatever here doesn't work   @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_starting_point);     counter = 0;      add = (button) findviewbyid(r.id.buttonadd);     sub = (button) findviewbyid(r.id.buttonsub);     display = (textview) findviewbyid(r.id.textview1);     add.setonclicklistener(new view.onclicklistener() {      //putting add.whatever here doesn't show suggestions either.

i've tried can think of working, deleting & reinstalling eclipse, deleting android eclipse , going through sdk setup again, changing workspace, creating entirely new project, deleting eclipse preference file, endless googling, resetting & altering settings, , can't life of me figure out what's causing this. ideas? thanks!
