It is not working with BottomSheetDialogFragment

[Zeliret]

For example this code:

    <com.otaliastudios.bottomsheetcoordinatorlayout.BottomSheetCoordinatorLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <com.google.android.material.appbar.AppBarLayout
                android:id="@+id/appbar"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:liftOnScroll="true"
                app:liftOnScrollTargetViewId="@id/picker_list">

                <androidx.appcompat.widget.Toolbar
                    android:id="@+id/toolbar"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:background="@color/white"
                    app:title="@{title}"/>
            </com.google.android.material.appbar.AppBarLayout>

            <androidx.recyclerview.widget.RecyclerView
                android:id="@+id/picker_list"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:clipToPadding="false"
                android:paddingBottom="@dimen/padding_narrow"
                android:paddingTop="@dimen/padding_narrow"
                android:scrollbarStyle="insideOverlay"
                android:scrollbars="vertical"
                app:layout_behavior="@string/appbar_scrolling_view_behavior"
                tools:ignore="UnusedAttribute"/>

        </com.otaliastudios.bottomsheetcoordinatorlayout.BottomSheetCoordinatorLayout>

leads to a crash.

java.lang.ClassCastException: android.widget.FrameLayout$LayoutParams cannot be cast to androidx.coordinatorlayout.widget.CoordinatorLayout$LayoutParams

i believe your com.otaliastudios.bottomsheetcoordinatorlayout.BottomSheetCoordinatorLayout also needs to be inside of a coordinator layout
