充气时出错 class android.support.v7.widget.CardView

Question

我们已经有一堆与此类似的问题，但它们都与向后兼容性有关，或者它们处于 eclipse 状态（据我所知），但我认为问题是在膨胀 cardView class 它在我的模拟器 (SDK 23) 上运行良好，但是当我在我的其他模拟器 (SDK 19) 上尝试它时出现此错误，错误指向我这一行：

    @Override
public RecyclerView.ViewHolder onCreateViewHolderImpl(ViewGroup viewGroup, final ParallaxRecyclerAdapter<Information> adapter, int i) {

    LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
    return new ViewHolder(inflater.inflate(R.layout.custom_row, viewGroup, false)); // this line

}

我也试过 getActvity().inflate..... 而不是上面提到的，但仍然存在同样的错误，我也检查了我的 gradle，这里一切似乎都很好：

dependencies {

compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.mikhaellopez:circularimageview:2.1.1'
compile 'com.isseiaoki:simplecropview:1.0.16'
compile 'com.android.support:recyclerview-v7:23.4.0'
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:cardview-v7:23.4.0'
compile 'com.android.support:support-v4:23.4.0'
compile('com.github.afollestad.material-dialogs:core:0.8.5.3@aar') {
    transitive = true
}

我的错误：

试试这个对你有帮助删除这个 android:foreground="?android:attr/selectableItemBackground"

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:paddingLeft="4dp"
android:paddingRight="4dp"
android:paddingBottom="2dp">

<android.support.v7.widget.CardView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/cardview"
    card_view:cardBackgroundColor="@android:color/white"
    card_view:cardElevation="2dp"
    card_view:cardMaxElevation="2dp"
    card_view:cardUseCompatPadding="true">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">



....here i have a bunch of other layout elements
         </RelativeLayout>
    </android.support.v7.widget.CardView>



</LinearLayout>
