当我尝试在版本为4.4的Android设备上对CardView / RecyclerView进行充气时，我正面临这种InflateException请注意我在版本超过4.4或Kitkat的任何设备上都没有遇到此问题。
请是异常的堆栈跟踪

Kitkat不支持RecyclerView / CardView吗？或任何其他原因？请帮忙。
以下是发生异常的代码
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
v = inflater.inflate(R.layout.row_layout_course, parent, false);
下面是我试图膨胀的xml。
please find below is the xml code.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

答案 0 :(得分：1)
尝试从您的tools:targetApi="lollipop"
CardView
并使用此
android:foreground="?android:attr/selectableItemBackground"
而不是这个
android:foreground="?android:attr/selectableItemBackgroundBorderless
<强> CODE
<android.support.v7.widget.CardView
android:foreground="?android:attr/selectableItemBackground"
app:cardCornerRadius="10dp"
android:layout_width="match_parent"
android:layout_margin="@dimen/cardview_compat_inset_shadow"
android:layout_height="wrap_content"

确保包含CardView的依赖项。 要添加依赖项，请在模块gradle的依赖部分
中添加以下行dependencies {
compile 'com.android.support:cardview-v7:X.X.X'
}
（用您的版本替换X）
确保使用app:srcCompat在ImageView中使用矢量图像。
如果您使用矢量图像作为顶部/底部/右/左可绘制或复选框按钮，则21以下矢量图像不能直接支持drawable。
有关矢量支持的更多信息，您可以查看 How to use vector drawables in Android API lower 21?
