다국어 지원을 구현하려고 할 때 응용 프로그램이 중단됩니다.

Question

내 응용 프로그램에 다국어 지원을 구현하려고합니다. 지금까지 내가 한 모든 것은 'values'폴더를 복사하여 'values-ru'로 붙여 넣어 러시아어를 지원하는 것입니다. 나는 문자열 값을 변경하지 않았고 그대로 그대로 두었다. 그런 다음 에뮬레이터를 러시아어로 전환하고 앱을 설치했습니다. 하지만 일단 실행하면 오류가 발생하고 LogCat에서 다음과 같은 오류 메시지가 나타납니다.

Answer 1

나는 문제가 있음을 확신 해요 language has a greater precedence than other qualifiers은 대체 자원의 어떤에 결정할 때 제공 자원 테이블에 따라 사용하십시오 (가장 일치하는 알고리즘은 here 참조). 당신이 values-v14에서 그 예를 들면 다음 values-ru 자원을 넣으면

그래서, 는 사용되지 않습니다. 이 경우 작업 막대가 잘못 구성되었을 가능성이 있습니다 (values의 리소스가 장치의 API 수준이 낮음을 가정하고 values-vxx에서 재정의 된 경우).

전체 폴더가 아닌 strings.xml을 values-ru (실제로 사용자 지정하려는 다른 리소스와 함께)에만 복사해야합니다.
