エラー：IllegalArgumentException：このコンポーネントのスタイルでは、アプリのテーマがTheme.MaterialComponentsである必要があります

以下は私の依存関係です

implementation 'com.google.Android.material:material:1.0.0'
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

私のlayout.xml

<?xml version="1.0" encoding="utf-8"?>

        app:layout_anchor="@id/bottomBar"
        app:srcCompat="@drawable/ic_apps" />

</androidx.coordinatorlayout.widget.CoordinatorLayout>

上記のコードは私にとってはうまく機能しています

しかし、material designのdependenciesを更新すると

implementation 'com.google.Android.material:material:1.1.0-alpha01'

エラーが発生しています。

material:1.1.0-alpha01に問題があります

シンプルな2つのソリューション

最初のソリューション

親テーマを変更する

<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
        <!-- Customize your theme here. -->

</style>

2番目のソリューション

安定版になるまでmaterial designの古いdependenciesを使用

implementation 'com.google.Android.material:material:1.0.0'

これが他の誰かに役立つことを願っています

Gradleの依存関係を変更し、コードをスタイルコードでうまく機能させる

<!-- Base application theme. -->
<style name="AppTheme" parent="**Theme.MaterialComponents.Light.DarkActionBar**">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
    <item name="Android:activatedBackgroundIndicator">@drawable/drawer_list_selector</item>
    <item name="Android:textColorSecondary">@color/black_overlay</item>
    <!--<item name="Android:windowBackground">@drawable/nav_menu_background</item>-->
