데이터베이스에서 컬러 코드를 받아서 적용시키는 방식으로 만든 앱인데 각 그리드 뷰를 클릭할 때마다 해당 색상이 보여지는 다이얼로그를 출력하고 싶은데 어디다 넣어야 할지 모르겠네요ㅠ 도와주세요!!

Answer 1

Adapter 에서 구현하셔야 할 것같네요. getView() 에서 view 에게 click 이벤트를 달아보세요. log 를 남겨 정상적으로 아이템 선택이 된다는것이 보여지면 각각의 아이템에 따른 색상을 다이어로그로 띄워주면 됩니다.

getView()에서 view에게 클릭 이벤트를 넣고 다이얼로그를 출력해야하는데 다이얼로그 AlertDialog.Builder dlg = new AlertDialog.Builder(this); 이렇게 하면 빨간줄이 뜨는데 저 this부분을 어떻게 처리해야 하는건가요?
