갤럭시A에서는 가로 세로 정방향으로 다 문제 없구요
현재 카메라 구동소스 인데요, 갤럭스S에서 문제가 발생합니다.
세로 모드로 했을 때는 화면은 나오는데 90도 회전이 되서 나오구요.
가로모드로 했을 때는 화면이 멈추어서 움직이지 않습니다. 그런데 찍으면 제대로 된 화면이 출력되더라구요.
세로모드 일 때 camera.getParameters().setRotation(90); 써서 카메라를 돌려볼려고 하는데 돌아가지 안습니다.
저는 세로 모드로 구현했으면 좋겠거든요. 카메라좀 돌아가게할 수 있는 방법이 있나요??
안되면 가로모드로 구현하는 방법도 괜찮습니다.
답변좀 부탁드리요!
