안드로이드 스튜디오 2.1 데이터 바인딩은 기호를 해결할 수

Question

다음에 내가 build.gradle(project)에 classpath "com.android.databinding:dataBinder:1.0-rc4"을 추가 한 build.gradle (module app) 에 dataBinding { enabled true }을 추가로 내 프로젝트 구조는 내 활동의 레이아웃이 activity_fullscreen.xml 그래서 내가 ActivityFullscreenBinding를 사용하려고하고는 "기호를 확인할 수 없습니다"가져온다 오류. 가져올 필요가 있는게 있나요? 참고로 난 이미 여기 Gradle을 2.1.0 를 사용하고 안드로이드 스튜디오 2.1 를 사용하고있어 레이아웃 XML은 layout 태그로 포장되어야한다 activity_fullscreen.xml

귀하의 activity_fullscreen.xml은 다음과 같이해야합니다 :

Build -> RebuildProject.
