앱개발 질문

프로페셔널 안드로이드 책 관련 소스 실행 오류 관련 문의 입니다.
내용은 이해가 가는데 실행하려니 에뮬레이터에서 오류가 나네요.
에뮬레이터 오류 내용은 캡쳐 화면으로 올립니다.

향긋한소리

LogCat을 보시면 에러 내용이 나옵니다.. 그걸 올려 주세요.. 그래야 뭐가 잘 못 됐는지 쉽게 파악 할 수 있거든요..

http://www.androidpub.com/1093 공지사항을 한번 읽어보시기 바랍니다. 에러 발생시 로그캣 보는법도 다 설명되있습니다. 가져와 붙여주세요

ClearableEditText에 다음과 같은 생성자를 추가해보세요.

public ClearableEditText(Context context, AttributeSet attrs) {

this(context);

}

직접 테스트해보진 않았지만 위와같은 생성자가 없어서 생기는 문제입니다.

Caused by: java.lang.NoSuchMethodException: ClearableEditText(Context,AttributeSet)

Logcat에 진짜 다 나와있네요 ㅎㅎ
말씀하신대로 생성자 추가하고 해보니 잘되네요. 감사합니다. ^^ (__)
