android - Drawable as Background for CardView

Question

the CardView ( android.support.v7.cardview ) stays white even though I set a backround drawable via android:backround - The documentation gives me the feeling that it should work. No Idea what I am doing wrong here.

I know this is an old question, but I have a simple solution - just make the first child of your CardView an ImageView and specify the scale type to fitXY. You can get rid of the extra CardView padding by setting cardElevation and cardMaxElevation to 0dp:

<?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"
    android:layout_width="match_parent"
    android:layout_height="200dp"
    app:cardCornerRadius="4dp"
    app:cardElevation="0dp"
    app:cardMaxElevation="0dp">

    <ImageView
        android:src="@drawable/your_background"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="fitXY"/>

    <... your layout

    .../>


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