아래 소스는 wi-fi AP목록을 가져와서 화면에 뿌려주는 activity인데요.
여기에 각 wi-fi AP 목록마다 새로운 imagebutton을 넣어서 특정 기능(wifi 차단)을 on/off하려고 하는데요.
아래와 같이(그림이 조금 이상하긴 하지만) 기능이라는 ap마다의 버튼을 클릭하면
해당 wifi AP를 차단할수 있도록 하고 싶은데요.
ap가 몇개가 생길지 모르기때문에 ap 개수에 따라서 버튼이 그 옆에 자동적으로 생성될 수 있도록 구현하려고 합니다.
어떤 기능을 이용해야 할지요?
혹시 꼭 wifi가 아니더라도 비슷한 걸 해보신 분은 공유 부탁 드립니다.
그리고 그 on/off 정보를 저장해야 하는데 어떤 식으로 할 수 있는건가요?
