내 앱이 간단한 "밝기 체인저"이며 시스템 밝기도 변경됩니다 (구현하기 쉽지 않은 항목 : D).
실제로 모든 것을 설정하고 잘 작동합니다 ... 조금 성가신 경우를 제외하고 ... 밝기가 변경 될 때마다 화면이 처음으로 최고 밝기 (예 : 100 % 밝기)로 "깜박"하고 0.5 초 후 , 올바른 밝기로 변경됩니다.플래시가 시스템 밝기를 변경하는 중
예 (MAX.) (255)로 변경, 120
adter 절반에 제 2 변화가 여기 내 두 클래스 코드 : 시스템 밝기 120이어야한다. Dummy 클래스는 밝기 변경 적용에 필요한 "재설정"에 사용됩니다.
EDIT : btw. 나는 문제가 "lp.screenBrightness = 100/100.0f;"라고 생각한다. 어리 석음에. 그러나 못해없이 작동 :/
