2가지 문제가 있어 어떻게 고쳐야 되는지 막막합니다...

지금은 컴파일 다 잘되고, 실행까진 가능한데, 저 Convert 버튼 누르면 에러납니다...

그리고 After왼쪽에 있는 박스에, forResult(단위 변환후) 값을 널려고 하는데 어떻게 해야하는지요...

forResult 옆에있는 " " 지우면 컴파일에 에러납니다...

val1 에다가 BeforeBox의 값을 저장할려고 하는데, 저 val1 = (R.id.AfterBox)로는 주소값이 저장이 되니

무슨 코드를 선언해야 되는지요.... 초보라서...ㅎㅎ;;

도와주세요.... ^^;

이렇게 코딩하였습니다....

조금 급한데 부탁합니다....^^
