Android 12 启动画面 API 无法与 Material 组件配合使用

Question

我一直在关注文档，但不幸的是它不包括使用材质组件作为应用程序整体主题时的适应。

<style name="Theme.App" parent="Theme.MaterialComponents.DayNight">
    <!-- Primary brand color. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryVariant">@color/colorPrimaryDark</item>
    <item name="colorOnPrimary">@android:color/white</item>
    <!-- Secondary brand color. -->
    <item name="colorSecondary">@color/colorPrimary</item> <!--Fab color-->
    <item name="colorOnSecondary">@color/colorAccent</item> <!--Fab icon color-->
    <item name="colorSecondaryVariant">@color/colorAccentDark</item>
    <!-- Status bar color. -->
    <item name="android:statusBarColor">?attr/colorPrimaryVariant</item>
    <!-- Customize your theme here. -->
    <!--<item name="tabStyle">@style/AppTabLayout</item>-->
    <!-- The color for all other text including the menu -->
    <item name="android:textColor">@color/colorPrimary</item>
    <item name="android:textColorHighlight">@color/colorAccentDark</item>
    <item name="android:windowAnimationStyle">@style/WindowAnimationTransition</item>

    <item name="checkboxStyle">@style/AppCheckBoxStyle</item>
    <item name="popupMenuBackground">@drawable/popup_bg_rounded</item>
    <item name="materialAlertDialogTheme">@style/AppDialogTheme</item>

    <item name="autoCompleteTextViewStyle">@style/AppCursor</item>

    <item name="overlapAnchor">false</item>
    <item name="android:dropDownVerticalOffset">?attr/actionBarSize</item>

    <item name="android:forceDarkAllowed" tools:targetApi="q">false</item>
</style>

<style name="Theme.App.Starting" parent="Theme.SplashScreen">
        <item name="windowSplashScreenBackground">
            @color/whitePrimaryDark
        </item>
        <item name="postSplashScreenTheme">
            @style/Theme.Cryptonian.NoActionBar
        </item>
    </style>

安卓清单

    <activity
        android:name=".presentation.MainActivity"
        android:exported="true"
        android:screenOrientation="portrait"
        android:theme="@style/Theme.App.Starting"
        android:windowSoftInputMode="adjustPan">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

它因错误而崩溃

  Caused by: java.lang.IllegalArgumentException: The style on this component requires your app theme to be Theme.AppCompat (or a descendant).

有人面临同样的问题吗？

super.onCreate()解决方案是在调用之前安装 Splash Screen APIsetContentView
