在我的应用布局中使用 com.google.android.material.bottomnavigation.BottomNavigationView 时，出现以下错误：
Caused by: android.view.InflateException: Binary XML file line #25 in com.example:layout/activity_main: Error inflating class com.google.android.material.bottomnavigation.BottomNavigationView
Caused by: java.lang.IllegalArgumentException: The style on this component requires your app theme to be Theme.AppCompat (or a descendant).
请注意，这仅发生在运行深色模式的 Android 11 设备上。在 Android 11 中使用灯光模式时，一切正常。
这是基本应用程序主题：
<style name="AppStyle" parent="Theme.Material3.DayNight.NoActionBar">
<style name="AppStyle.NavActive" parent="Widget.Material3.BottomNavigationView.ActiveIndicator">
<item name="android:color">@color/surface</item>
</style>
这在主题/夜晚中使用：
<style name="AppStyle" parent="Theme.Material3.DayNight.NoActionBar">
即使我将其更改为 Theme.AppCompat、Theme.MaterialComponents 等，应用程序仍然会崩溃。
为什么会这样？尽管浅色和深色主题相同，但应用程序在深色模式下仍会崩溃。在较新的 Android 版本中，这种情况不会发生。到目前为止，只有深色模式下的 Android 11 存在这些问题。
这些是使用的 gradle 版本：
implementation 'com.google.android.material:material:1.11.0'
implementation 'androidx.appcompat:appcompat:1.6.1'
这里的答案：
此组件上的样式要求您的应用程序主题为 Theme.MaterialComponents （或后代）
没用。

检查主题中的所有颜色值是否设置正确。如果某些值（例如 textPrimary 或 colorAccent）设置为不存在的值，则会发生崩溃。
而且崩溃消息非常具有误导性，该问题与 Theme.AppCompat 无关
