@ChrisJenkins 메서드를 사용자 지정 했으므로 RatingBar 아이콘의 크기와 등급 지정 이미지의 사용자 지정 색조 색을 설정할 수 있습니다. RatingBar에 패딩을 설정하거나 사용자 정의 너비와 높이를 설정할 수 있습니다. @ChrisJenkins 솔루션은 완전히 사용자 정의 가능한 RatingBar를 만들기 위해 많은 도움을주었습니다. XML의 매개 변수도 설정할 수 있습니다.

앞으로 어떤 독자라도 볼 수 있도록 - 이것은 완벽하게 작동합니다. 그러나 ColorFilter를 사용하면 drawable에 색상을 추가 할 때 색상이 곱 해집니다. ColorFilter filter = new LightingColorFilter (0, color);를 사용하는 것이 좋습니다. 원래 색상을 대체합니다. – ravindu1024
감사합니다. 나는 그것을 살펴볼 것입니다! – box
