사용자 지정 어댑터가있는 목록 뷰가 있습니다. listView의 사용자 정의 행에는 클릭 할 때 무언가를 처리해야하는 2 개의 이미지 버튼이 있습니다. 하지만 응용 프로그램을 시작하고 imagebutton을 클릭하면 아무 일도 일어나지 않지만, 먼저 행을 클릭 한 다음 imageButton을 클릭하면 내 클릭이 처리되기 때문에 원하는대로 잘 작동하지 않습니다. 다른 사용자에게 도움이되는 몇 가지 솔루션을 시도했지만, 아무도 그저 행 클릭 후 처리되는 것과 똑같은 문제가 없었습니다.사용자 지정 목록보기 내에서 imageButton 클릭 처리

이것은 효과가 있습니다. 하지만 이미지 버튼을 클릭하면 이름이 부여되지 않습니다. 이것을 holder.name으로 변경했는데 더 이상 홀더가 필요하지 않습니까? 사용 된'String btnmsg = ""+ holder.name; "에 대한 삭제 가져 오기 – mXX
