Adding selectableItemBackground, as well as a colored background

Question

I added selectableItemBackground to the CardView, which is displayed in recyclerview mode. Each CardView displays text and image. each card can be selected, and to add a ripple effect when pressed, I added:

android:background="?attr/selectableItemBackground"

The problem is that now I can not set the background color. these two lines together indicate an error:

android:background="?attr/selectableItemBackground"
android:background="#FFFFFF"

How can I color the layout background and also add a ripple effect using selectableItemBackground.

full code card_view.xml:

<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:id="@+id/card_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="2dp"
    card_view:cardCornerRadius="10dp">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="?attr/selectableItemBackground"
        android:orientation="vertical">
        <!--CANT ADD THIS: android:background="#FFFFFF"-->

        <TextView
            android:id="@+id/singleTextLine"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_margin="3dp"
            android:text="Test"
            android:textSize="30dp" />

        <ImageView
            android:id="@+id/singleImage"
            android:layout_width="fill_parent"
            android:layout_height="125dp"
            android:layout_gravity="center_horizontal"
            android:layout_margin="3dp" />

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

The problem is that I cannot paint the background color white by combining the attr / selectableItemBackground effect for the ripple effect, and then it looks like this:

- FrameLayout ( ) TextView

<FrameLayout

    android:layout_height="wrap_content"
    android:background="@color/category_numbers">

Answer 3

Now we can achieve this better.

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#FFFFFF" //ACTUAL BACKGROUND
    android:foreground="?selectableItemBackground" //RIPPLE EFFECT
    android:orientation="vertical">
