에서 Java 클래스의 메소드를 호출 할 수 없습니다. 사용자가 연락처와 메시지를 입력 한 다음 버튼 butenc을 클릭하는 sms 애플리케이션을 만들고 있습니다. 버튼은 메소드가 데이터를 수신하고 조작하는 다른 자바 클래스에 가변 전화 번호와 메시지를 보내야합니다. Ecc java 파일은 메시지 조작을위한 다양한 다른 Java 클래스에 링크되는 독립형 Java 클래스입니다. 몇 번 stackoverflow 오류가 발생하고 코드에서 몇 가지를 조작하면 응용 프로그램이 실행되고 enc 버튼을 클릭해도 아무 일도 일어나지 않지만 보내기 버튼을 클릭하면 메시지가 전송됩니다. Ecc 클래스에 변수를 전달할 때 문제가 있다고 확신합니다. OS에 관한 여러 가지 질문을했지만 그 중 누구도 문제를 해결하지 못했습니다. 내가 변경 한 것은 위에 언급 한 문제 중 하나를 제공합니다. 이 문제를 어떻게 극복 할 수 있습니까?활동 클래스
