未能在当前主题中找到样式'cardView Style'

Question

更新支持库版本后,27.1.0 Android Studio无法呈现CardView.它显示错误消息

failed to find style 'cardView Style' in current theme

但是在编辑时没有错误,并且在手机上看到没有区别.

我已经将支持库版本恢复为27.0.2并且它正常呈现.

支持库或Android工作室的问题？如何解决这个问题？

Answer 1

检查一个的源CardView可以看到构造函数

public CardView(@NonNull Context context, @Nullable AttributeSet attrs) {
    super(context, attrs);
    initialize(context, attrs, 0);
}

已改为

public CardView(@NonNull Context context, @Nullable AttributeSet attrs) {
    this(context, attrs, R.attr.cardViewStyle);
}

并且新属性cardViewStyle在库中定义.我想由于某些原因,Android Studio预览不包括库中此属性的值.我不确定它是否通常会解析库中定义的自定义属性,这是一个错误,或者如果是这样的话.

解决方法1

解析主题中的属性(可能仅在调试版本中),这样错误就消失了.@style/CardView已经在支持库中定义,因此您不需要创建样式,只需引用它.

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="cardViewStyle">@style/CardView</item>
</style>

务必AppTheme在布局预览和清理构建中使用.

解决方法2

添加带有tools命名空间的样式,以便它不会影响您的生产代码.将记录渲染错误,但CardView无论如何您都会看到

<android.support.v7.widget.CardView
    tools:style="@style/CardView"
    ...

好消息

Android Studio 3.1似乎正确处理此问题,无需解决方法(尽管仍然记录了布局预览中的错误).

在Android Studio 3.2(目前在Canary频道)中,错误消失了.

Answer 2

我也有同样的问题,所以我补充道

<item name="cardViewStyle">@style/CardView</item>

在我的styles.xml文件中.但是它显示了一个警告"资源@ style/CardView在com.android.support:design中被标记为私有".

所以,之后我尝试了这个

<item name="cardViewStyle">@style/CardView.Light</item>

这对我有用.我使用的是Android Studio 3.1.4和Gradle 4.4.
