문제
화면 방향이 변경되는 경우 이벤트를 얻을 수 있습니다
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
.
가 설정되어 있습니까?
사용자가 전체 화면 모드로 비디오를 열면 화면이 가로가됩니다.
사용자가 (뒤로) 인물로되면 비디오가 최소화됩니다.
해결책
시도 :
private OrientationEventListener mOrientationEventListener;
private int mOrientation = -1;
private static final int ORIENTATION_PORTRAIT_NORMAL = 1;
private static final int ORIENTATION_PORTRAIT_INVERTED = 2;
private static final int ORIENTATION_LANDSCAPE_NORMAL = 3;
private static final int ORIENTATION_LANDSCAPE_INVERTED = 4;
