Question

我正在尝试从新的Android设计支持库23.2.0实现BottomSheetDialog。我有layout GoogleMap Fragment，Toolbar和几个晶圆厂。

问题

接下来是问题：展开BottomSheetDialog并向上滚动NestedScrollView时，BottomSheetDialog不会崩溃，只有当我AppBarLayout BottomSheetDialog时，它才会崩溃1}}下来。我想要展开BottomSheetDialog滚动NestedScrollView。

问题＃2

如何创建这样的BottomSheetDialog？

我的代码

我的BottomSheetBehavior：

View bottomSheet = rootView.findViewById(R.id.bottom_sheet);
        BottomSheetBehavior bottomSheetBehavior = BottomSheetBehavior.from(bottomSheet);
        bottomSheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
            @Override
            public void onStateChanged(@NonNull View bottomSheet, int newState) {
                Log.d(TAG, "setUpMap() -> onStateChanged() -> newState: " + newState);
            }

            @Override
            public void onSlide(@NonNull View bottomSheet, float slideOffset) {
                Log.d(TAG, "setUpMap() -> onSlide() -> slideOffset: " + slideOffset);
            }
        });

        bottomSheetBehavior.setPeekHeight((int) Utils.convertDpToPixel(100f, this));

我的XML：
