주소록 불러와 체크박스 생성 중에 문제가 생깁니다.

Question

주소록을 불러오는 것만 했을 때는 문제없이 실행이 되는데

옆에 체크박스 생성을 하려고 하는데

어플리케이션 실행이 안됩니다ㅠㅠ

뭐가 문제일까요?ㅠ

Answer 1

hasPhoneNum 변수나

phones 변수에 Null에러가 나는거같은데요~

체크박스를 생성하려는 코드를 넣기 전에는 문제없이 전화번호 리스트를 잘 가져왔는데 왜갑자기 거기에서 에러가 발생하는걸까요.......

일단 DDMS에서 에러가난라인을 더블클릭해서 디버깅 or Log를 찍어보시길바랍니다~ 어디서 nullpointer가 나는지요~

제가 몇라인에 에러가난다라는게 표시가안나와서 딱히 드릴말씀이없습니다...
