SlidingDrawer 자체 적응 내용 너비

먼저 효 과 를 보 세 요. 그림 의 파란색 구역 은 SlidingDrawer 이 고 SlidingDrawer 가 닫 히 며 열 렸 을 때 빨간색 구역 과 녹색 구역 이 자동 으로 적응 합 니 다.

참고:http://stackoverflow.com/questions/3654492/android-can-height-of-slidingdrawer-be-set-with-wrap-content
위 주소 에서 말 한 빨간색 구역 은 자동 으로 적응 되 지 않 습 니 다.
빨간색 영역 자동 적응 사고:
간단 하 다 isOpened () 상 태 는 각각 너비 나 높이 를 계산한다.
SlidingDrawer 가 닫 히 거나 열 렸 을 때 requestLayout () 를 다시 호출 하여 layot 폭 을 계산 합 니 다.
다음은 수 정 된 코드 입 니 다.
