내 응용 프로그램은 데이터베이스에 데이터를 삽입하고이 데이터를 listView에 저장합니다. 사용자가 listview에서 항목을 클릭하면이 정보를 textView 형식에서 사용할 수 있습니다. 하지만 textView에서 회 전자 항목을 조정하는 방법은 무엇입니까?Spinner 항목을 TexView에 적용하는 방법

이 코드를 수정하는 데 도움을주십시오. 스피너 선택은 데이터베이스에 올바르게 삽입되지만 textView 형식으로 표시하는 방법은 무엇입니까?
자바 코드가 내 코드를 showemployee() 함수에서 봐 주어야한다. –
