커스텀 리스트뷰를 만들기 위해서 새로운 액티비티를 만들고 생성자를 만들었는데 @androidx.annotation.Nullable AttributeSet attrs 이부분에서 에러가 나네요 구글에 검색해서 compile 'com.android.support:support-annotations:23.4.0' 추가도 해봤는데 WARNING: Configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'. It will be removed at the end of 2018. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html Affected Modules: app 이런식으로 오류가 나네요
