错误:找不到cardElevation和cardUseCompatPadding

Question

更新Android Studio 2.3.3后3.0,XML中的CardView找不到cardElevation和cardUseCompactPadding.我目前的支持库版本26.1.0

这是xml代码:

<android.support.v7.widget.CardView
app:layout_scrollFlags="scroll|enterAlways"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:cardUseCompatPadding="true"
android:id="@+id/cardS"
app:cardElevation="5dp">
<android.support.v7.widget.SearchView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginEnd="20dp"
    android:id="@+id/search_fragment_searchViewQuery"
    app:popupTheme="@style/AppTheme"
    app:iconifiedByDefault="false"
    android:layout_marginRight="20dp" />
</android.support.v7.widget.CardView>

日志错误:

Error:error: attribute 'com.y34h1a.project:cardElevation' not found.
Error:error: attribute 'com.y34h1a.project:cardUseCompatPadding' not found.
Error:attribute 'com.y34h1a.project:cardElevation' not found.
Error:attribute 'com.y34h1a.project:cardUseCompatPadding' not found.

还有其他错误:

Error:failed linking file resources.  
Error:java.util.concurrent.ExecutionException: 
java.util.concurrent.ExecutionException: 
com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for 
details
Error:java.util.concurrent.ExecutionException:

details
Error:com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs 
for details
Error:Execution failed for task ':app:processDebugResources'.
> Failed to execute aapt

清理和重建项目无法解决此问题.

甚至在将Android Studio从2.3.3更新到3.0之后我遇到了同样的问题

我做了以下帮助我克服了这个问题 -

1.将compileSdkVersion更新为26

compileSdkVersion 26

2.将targetSdkVersion更新为26

targetSdkVersion 26

3.将Cardview支持库更新到26.1.0

implementation 'com.android.support:cardview-v7:26.1.0'
