MaterialCardView 与材质崩溃：1.1.0

BaR*_*Rud 29 android android-layout android-cardview material-components material-components-android

我使用 MaterialCardView 作为我的cardview布局。现在，Android-studio 开始向我展示，而不是 current implementation "com.google.android.material:material:1.0.0"，我应该更新到1.1.0

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/edit_name"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:orientation="vertical"
    android:layout_margin="@dimen/activity_vertical_margin">

  <com.google.android.material.card.MaterialCardView
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      app:cardCornerRadius="8dp"
      app:cardElevation="8dp">

      <...more layout>
</com.google.android.material.card.MaterialCardView>
</LinearLayout>

使用 1.1.0，我崩溃了 Error inflating class com.google.android.material.card.MaterialCardView

所以，我有3种情况：

坚持1.0.0和使用MaterialCardView（工作，但不是首选）
更新到1.1.0（或 1.2.0-alpha）并使用androidx.CardView（工作，但不是首选）
更新1.1.0并更改MaterialCardView（首选，但不起作用）

由于我想使用选项 #3，而且我没有任何解决方案，有人可以提供线索吗？

更新我的风格（我也有风格和风格之夜。我在这里发布style唯一的）：

<resources>

  <!-- Base application theme. -->
  <style name="AppTheme" parent="Theme.AppCompat.DayNight">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
  </style>

  <style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
  </style>

  <style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

  <style name="ThemeOverlay.AppCompat.navTheme">
    <!-- Color of text and icon when SELECTED -->
    <item name="colorPrimary">#ffffff</item>
    <!-- Background color when SELECTED -->
    <item name="colorControlHighlight">@color/colorPrimary</item>

您也可以将它保存在您的 materialcardview 本身中：

 <com.google.android.material.card.MaterialCardView
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      app:cardCornerRadius="8dp"
     **** android:theme="@style/Theme.MaterialComponents.Light"  *****
      app:cardElevation="8dp">

错误在堆栈跟踪中：

引起：java.lang.IllegalArgumentException：此组件上的样式要求您的应用主题为 Theme.MaterialComponents（或后代）。

对于 1.1.0 版本，您必须从Theme.MaterialComponents.

将您的应用主题更改为

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

You need to change your AppTheme to have it's parent theme as a descendant of MaterialComponent

In your particular case changing the AppTheme from

  <style name="AppTheme" parent="Theme.AppCompat.DayNight">

to

  <style name="AppTheme" parent="Theme.MaterialComponents.DayNight">

就我而言，我刚刚添加了android:theme=""属性并且它起作用了。我的材料卡视图元素如下 -

<com.google.android.material.card.MaterialCardView
            android:id="@+id/edit_profile_card"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginStart="@dimen/dp_16"
            android:layout_marginTop="@dimen/dp_10"
            android:layout_marginEnd="@dimen/dp_16"
            android:layout_marginBottom="@dimen/dp_10"
            **android:theme="@style/Theme.MaterialComponents.DayNight"**
            app:cardCornerRadius="@dimen/dp_10"
            app:cardElevation="@dimen/dp_20"
            app:state_dragged="false">

           ....
           ....

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