Applying Image background for the Textview is not good in your case, Instead of that you can create ImageView and Textview different and apply what ever properties you need.

it should look something like below.

<android.support.v7.widget.CardView
        xmlns:card_view="http://schemas.android.com/apk/res-auto"
        android:layout_gravity="center"
        android:layout_width="match_parent"
        android:layout_height="140dp"
        card_view:cardCornerRadius="10dp"
        android:layout_margin="15dp"
        card_view:cardElevation="20dp"
        android:textColorHighlight="@color/cardview_dark_background"
        app:cardBackgroundColor="#000000"
        >

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@drawable/recp_one"
            android:alpha="0.5"/>

        <TextView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:text="ICE CREAM WITH CRANBERRY SYRUP"
            android:textAlignment="center"
            android:textColor="#FFFFFF" />

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