将BadgeDrawable与BottomNavigationView一起使用时出现不支持的OperationExcep

Question

我将BadgeDrawable与BottomNavigationView一起使用。但是当我把徽章放在底部导航视图的图标中时，我会得到这个异常

当请求成功时，我正在LiveData的Observe回调中设置徽章的数量。

这是我的视图

<com.google.android.material.bottomnavigation.BottomNavigationView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:id="@+id/bottom_navigation"
android:background="@android:color/transparent"
app:menu="@menu/bottom_navigation_menu"
app:itemBackground="@drawable/navigation_background_selector"
app:itemIconTint="@color/text_color_drawer_selector"
android:padding="5dp"
app:labelVisibilityMode="unlabeled"
app:elevation="0dp"
/>

我如何设置徽章的编号

int menuItemId = bottom_navigation.getMenu().getItem(1).getItemId();
BadgeDrawable badge = bottom_navigation.getOrCreateBadge(menuItemId);
badge.setNumber(20);

和我的风格

<style name="Theme.app" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Primary brand color. -->
<item name="colorPrimary">@color/purple_500</item>
<item name="colorPrimaryVariant">@color/purple_700</item>
<item name="colorOnPrimary">@color/white</item>
<!-- Secondary brand color. -->
<item name="colorSecondary">@color/teal_200</item>
<item name="colorSecondaryVariant">@color/teal_700</item>
<item name="colorOnSecondary">@color/black</item>
<!-- Status bar color. -->
<item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
<!-- Customize your theme here. -->
<item name="colorAccent">@color/colorAccent</item>
</style>
