我使用导航控制器显示了底部工作表,但未显示背景可绘制对象

当我使用时:

<dialog
    android:id="@+id/countriesBottomSheet"
    android:name="ru.ttcreate.nravki.ui.screens.login.authorization.CountryBottomSheetFragment"
    tools:layout="@layout/login_bottom_sheet_countries" />
findNavController().navigate(R.id.countriesBottomSheet)

我明白了:

当我使用时:

val bottomSheetBehaviorCountries = BottomSheetBehavior.from<LinearLayout>(binding.bottomSheetCountries as LinearLayout?)
bottomSheetBehaviorCountries.state = BottomSheetBehavior.STATE_EXPANDED

我明白了:

enter image description here

login_bottom_sheet_countries.xml的根LinearLayout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/bottom_sheet"
    android:layout_width="match_parent"
    android:layout_height="182dp"
    android:background="@drawable/rect_top_corners_white"
    android:orientation="vertical"
    app:behavior_hideable="true"
    app:behavior_peekHeight="0dp"
    android:clickable="true"
    app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior"
    android:focusable="true">
