android,如何在使用Theme.appcompat.light.DarkActionBar的同时使用MaterialCardView

Question

该应用程序将androidX与minSdk 21一起使用，并使用

<style name="myAppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="colorPrimary">@color/theme_colorPrimary</item>
        <item name="colorPrimaryDark">@color/theme_colorPrimaryDark</item>
        <item name="colorAccent">@color/theme_colorAccent</item>
    </style>

AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES) // or AppCompatDelegate.MODE_NIGHT_NO

<com.google.android.material.card.MaterialCardView
        style="@style/myCardViewStyle"
        ...>

    </com.google.android.material.card.MaterialCardView>

...

  <style name="CustomCardViewStyle" parent="@style/Widget.MaterialComponents.CardView">
     <item name="shapeAppearanceOverlay">@style/ShapeAppearanceOverlay_card_custom_corners</item>
  </style>

<style name="ShapeAppearanceOverlay_card_custom_corners" parent="">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSizeTopRight">0dp</item>
    <item name="cornerSizeTopLeft">0dp</item>
    <item name="cornerSizeBottomRight">8dp</item>
    <item name="cornerSizeBottomLeft">8dp</item>
  </style>

android.view.InflateException: Binary XML file line #573: Binary XML file line #573: 
Error inflating class com.google.android.material.card.MaterialCardView

AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES)

Material Components themes
The following is the list of Material Components themes you can use to get the latest component styles and theme-level attributes.

Theme.MaterialComponents
Theme.MaterialComponents.NoActionBar
Theme.MaterialComponents.Light
Theme.MaterialComponents.Light.NoActionBar
Theme.MaterialComponents.Light.DarkActionBar
Theme.MaterialComponents.DayNight
Theme.MaterialComponents.DayNight.NoActionBar
Theme.MaterialComponents.DayNight.DarkActionBar
Update your app theme to inherit from one of these themes, e.g.:

<style name="Theme.MyApp" parent="Theme.MaterialComponents.DayNight">
    <!-- ... -->
</style>

我看到应用程序中使用的theme.appcompat.light.darkactionbar在派生链中，最终备份到android:theme.material.light.noactionbar

<style name="Theme.AppCompat.Light.DarkActionBar" parent="Base.Theme.AppCompat.Light.DarkActionBar"/>
<style name="Base.Theme.AppCompat.Light.DarkActionBar" parent="Base.Theme.AppCompat.Light">
<style name="Base.Theme.AppCompat.Light" parent="Base.V21.Theme.AppCompat.Light"/>
<style name="Base.V21.Theme.AppCompat.Light" parent="Base.V7.Theme.AppCompat.Light">
<style name="Base.V7.Theme.AppCompat.Light" parent="Platform.AppCompat.Light">
<style name="Platform.AppCompat.Light" parent="Platform.V21.AppCompat.Light"/>

<style name="Platform.V21.AppCompat.Light" parent="android:Theme.Material.Light.NoActionBar">

并且theme.MaterialComponents.light.DarkActionBar从Android:theme.Material.light.NoActionBar中删除

Answer 1

试着在你的MaterialCardView中使用这个？

android:theme="@style/Theme.MaterialComponents.DayNight.DarkActionBar"

我相信，在您的MaterialCardView中添加此内容不会影响您的应用程序主题。
