Android 비디오 자막 Subtitle 과 가로 세로 화면 전환 예제 구현
최근 에는 동 영상 에 자막 을 넣 어야 한 다 는 수요 가 있 는데,사실 간단 하 다.자막 이 자주 사용 하 는 형식 은 srt 입 니 다.실제 텍스트 입 니 다.해석 한 다음 에 시간 에 따라 보 여 드 리 면 OK 입 니 다.그리고 회전 버튼 이 꺼 져 도 방향 감지 기 에 따라 가로 세로 화면 전환 이 가능 하 다 는 것 이다.
본 고 는 시스템 VideoView 를 사용 한 다음 에 sd 카드 에 있 는 동 영상 을 재생 하여 프 리 젠 테 이 션(소스 코드 에 f2.mp4 와 f2.srt 가 있 고 실행 할 때 sd 카드 로 복사 하면 됩 니 다)을 보 여 줍 니 다.다음은 소스 코드 를 간단하게 소개 합 니 다.
MainActivity 는 자막 을 표시 하고 가로 세로 화면 을 어떻게 전환 하 는 지 포함 합 니 다.
