Android BottomSheet: Is hiding under the toolbar

Answer 1

The AppBarLayout has a default elevation of 4dp (the dimension resource value design_appbar_elevation).

By default CoordinatorLayout, like any FrameLayout, will layout elements with higher elevation before lower elevation on API 21 and higher devices.

Try adding android:elevation="@dimen/design_appbar_elevation" to your layout.

Note that the elevation of a modal bottom sheet is @dimen/design_bottom_sheet_modal_elevation == 16dp
