        card_view:cardPreventCornerOverlap="false"
        android:foreground="?android:attr/selectableItemBackground"
        card_view:cardCornerRadius="2dp"

在你的rowitem中执行以下操作：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/cardcolor"
android:marginTop="2.5dp"
android:marginBottom="2.5dp"
android:layout_marginRight="5dp"
android:layout_marginLeft="5dp"
android:orientation="vertical">

<android.support.v7.widget.CardView
    android:id="@+id/card_view"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    card_view:cardElevation="0dp"
    card_view:cardPreventCornerOverlap="false"
    android:foreground="?android:attr/selectableItemBackground"
    card_view:cardCornerRadius="2dp"
    card_view:contentPadding="10dp"
    card_view:cardUseCompatPadding="false" >

    ..//body    

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


</LinearLayout>

并在父布局中为您的recyclerview提供保证金：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
layout_marginTop="2.5dp"
layout_marginBottom="2.5dp"
tools:context=".HomePageActivity">

<android.support.v7.widget.RecyclerView
    android:id="@+id/my_recycler_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="vertical"
    android:background="@color/white"/>

    </RelativeLayout>
