底页滚动问题

Question

我正在使用BottomSheet（bs）和google地图，我需要使bs和googlemap适应大小

然后，当bs展开时，地图将以较小的尺寸显示，而当bs折叠时，地图将以原始尺寸显示

先谢谢您

这里是班级和布局

 ConstraintLayout linearLayoutBSheet = view.findViewById(R.id.bottomSheet);
    bottomSheetBehavior = BottomSheetBehavior.from(linearLayoutBSheet);
    bottomSheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
        @Override
        public void onStateChanged(@NonNull View bottomSheet, int newState) {
            switch (newState){
                case BottomSheetBehavior.STATE_COLLAPSED:

                    break;
                case BottomSheetBehavior.STATE_DRAGGING:


                    break;

                case BottomSheetBehavior.STATE_EXPANDED:

                    break;

            }
        }

成功更改底表后，加载googlemap。
