Question

spinner가 3개인데 setOnItemSelectedListener를 다 붙이고 싶어요

그런데 spinner 한개에는 적용이 되는데 나머지에는 적용이 안돼요ㅠ.ㅠ

onItemClickListenr로는 세개 다 적용이 됐었는데 자꾸 튕기길래,

setOnItemSelectedListener로 바꾼거거든요.

왜 안될까요ㅠㅠ?

코드를 올려주세요... 말씀 해주신 내용으론 답을 해 드릴 수 없습니다.

이제 됐습니다! 그런데 실행하면 자꾸 꺼지는데 로그좀 봐주세요ㅠㅠ

코드를 달라고 했더니, 로그를 주셨네요..

아무튼 로그상 아래 부분을 보시면 됩니다.

10-21 19:26:08.317 29199-29199/com.example.sunhayoung.winintec1 E/AndroidRuntime:  Caused by: java.lang.NullPointerException
10-21 19:26:08.317 29199-29199/com.example.sunhayoung.winintec1 E/AndroidRuntime:     at com.example.sunhayoung.winintec1.Ohm.onButton1Clicked(Ohm.java:192)

해석하면 Ohm.java 파일의 onButton1Clicked 메소드의 192 라인에서 java.lang.NullPointerException 발생했습니다.
 왜 해당 라인에서 NullPointerException이 되었는지 확인 해 보시면 될 듯 하네요.

왜 났는지 정말 모르겠어요ㅠㅠ..

소스를 봐야할거같은데 지금 올려주신 로그로는 정확하게 뭐가 문제인지 몰라요..널포인트 익셉션 난거보니 뭔가 값이 없는거같은데 , 확인해보세요. 답변하는 분들은 코드를 모르니 192번째 줄에서 에러난거밖에 모르죠.
setOnItemSelectedListener 적용하시려면 스피너1-어댑터1-어댑터에 적용할 리스트1-스피너1과 어댑터1연동[setadapter] 이게 한세트입니다.

Answer 1

혹시 스피너 리소스를 하나로 계속 쓰시는지요?

소스를 올려보세요

그게 제일 정확합니다
