Android CardView设置成普通的Framelayout

比如可以这样写代码，CardView就变成普通的FrameLayout：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/selectableItemBackground"
    app:cardCornerRadius="0dp"
    app:cardElevation="0dp"
    app:cardPreventCornerOverlap="true"
    app:cardUseCompatPadding="true"
    card_view:contentPadding="0dp">

</android.support.v7.widget.CardView>
