저번에 removeView() 에러 관련해서 질문 올렸던 사람인데요
일단 화면으로 플래시를 쓰는 기능에 메뉴버튼을 누르면 색 설정 버튼이 나오고 그 버튼을 누르면
배경화면 색을 설정할 수 있는 AlertDialog창이 나옵니다.
여기엔 R, G, B 별로 Seekbar 3개가 있고 각 옆에는 EditText가 있어요. 대략..
이런 모습인데요, 저 Seekbar 를 움직이면 옆에 EditText에다가 Seekbar 조절값을 setText 하게 해주고
각 Seekbar를 조절하면 배경화면 색이 바뀌도록 코드를 짯는데 문제는 작동을 안하네요.
제가 inflate를 사용하여 View 객체를 가져왔는데 그 과정에서 뭘 하나 빼먹은거 같은데..
onProgressChanged 메소드 안에 Seekbar를 조절할때 로그를 찍어봤는데 로그도 안찍히네요. 마치 메소드가 작동하지 않는것처럼..
코드 올려드릴게요.
