시계어플 오류 질문입니다. 도와주세요~~

Question

아래는 실질적인 일을하는 class(clockview) 이구요...

그아래는 main액티비티입니다.~~

오류가 걸려서 올려봅니다.

로그켓이구요 ~~ 해결 해주시면 감사하겠습니다.~~

MidtermExam = 과제냄새

응? ㅋㅋ 생각지도 못한..!! 그런건가요 ;;
하지만 저 소스를 보면 아시겠지만 막코딩으로 실행만 되게 해놓은거라서 ㅋㅋㅋㅋㅋ
다듬으려면 약간의 공부는 하시겠죠 머

에러문구만 조금만 봐도 어느 부분이 오류인지 맥은 짚으실텐데..
킁킁..

감사합니다~ ㅠ 과제는 아니구요;;
이때까지 만들려던거 다 포기하고(너무 어려워서ㅠ)
가장 위젯이 간단하다고 하더라구요. 공부도 된다고 하고..
그래서 소스있으면 가져다가 공부할려는 목적이였습니다~
많은 고수분들께 감사합니다~
