그런데.... 시스템에서 언어를 변경해야 하는 방식으로 프로그래밍을 하면 전체 시스템 언어가 바뀌어서 여간 불편한 것이 아니다.
그래서 앱에만 적용되도록 바꿔주는 방법을 알아보도록 하자!!!
- // 로케일을 영어로 설정
- Locale en = Locale.US;
- // 환경설정 가져오기
- Configuration config = new Configuration( );
- // 환경설정 값에서 지역설정을 영어로 변경
- config.locale = en;
- // 리소스를 변경된 지역설정을 기준으로 갱신하기
- getResources( ).updateConfiguration( config, getResources( ).getDisplayMetrics( ) );
로케일이 변경된 다음에는 invalidateViews( ) 를 호출해줘야 변경된 언어로 화면이 갱신된다.
다음은 참고코드
