Android : ActivityThread.performLaunchActivity 오류

Question

디버거에서 내 프로그램을 부팅 할 때마다 ActivityThread.performLaunchActivity (ActivityThread $ ActivityRecord, Intent) 오류가 발생합니다. 프로그램이 시작되지 않습니다! 어떤 도움이라도 대단히 감사하겠습니다! 나는이 환경에 아주 새로운 사람이다. 더 이상 정보/코드가 필요하면 알려주세요.

Answer 1

귀하의 문제가 KidneyTest의 라인 57에 :

여기 내 로그 캣입니다.

프로그램이 호환되지 않는 형식으로 개체를 캐스팅하려고 시도 할 때 throw되는 ClassCastException을 오류 스택에 표시합니다.

캐스팅하고 EditText가 아닌 것으로 보입니다.
