제가 만든 안드로이드 계산기 코드입니다. 실행을 시키면 튕깁니다. 제가 잘못한 부분이 어딘지를 모르겠어서 질문합니다. 초보라서 고수님들께 질문올립니다.ㅠㅠ

이 앱은 최저임금값을 받아서 만약 일한 시간이 정해진 시간보다 많으면 급여를 추가(정해진 금액이나<시급> 최저임금에 float를 곱한 값<배수>을 추가)하여 계산하는 급여계산기입니다. 일~토까지 입력 후, 시작하는 날의 날짜와 요일 그리고 끝나는 날의 날짜를 받아서 만약 끝나는 날짜값이 시작날보다 작으면 해당 달의 마지막 날까지 더해서 계산하는 형식입니다.

혹시 수정할 부분이 있으면 수정해서 알려주셨으면 합니다.(저도 이렇게 큰건 안해봐서 체계적으로 알려주시면 감사하겠습니다.)

      startdate = Integer.parseInt(String.valueOf(editText_startdate));
    enddate = Integer.parseInt(String.valueOf(editText_enddate));

    editText_startdate 라는 EditText에서 문자열을 가져오신 후 Int로 변환하려고 하시는 것 같으신데

    지금 코드를 보시면 EditText에서 텍스트를 가져오지않아서 에러가 발생하는겁니다.

    input() 메소드에 작성하신 다른 코드들하고 비교해보세요.
