Border not appearing around MaterialCardView

I'm trying to add a border around my MaterialCardView control but for some reason this is not working. I've already added the relevant dependency but it still doesn't seem to have any effect.

Dependency added

dependencies {
    ...
    implementation 'com.google.android.material:material:1.0.0'
    ...
}

XML

<?xml version="1.0" encoding="utf-8"?>
<com.google.android.material.card.MaterialCardView
    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="wrap_content"
    android:layout_marginBottom="20dp"
    android:layout_marginTop="10dp"
    app:cardUseCompatPadding="true"
    app:cardBackgroundColor="@android:color/transparent"
    app:cardElevation="0dp"
    app:strokeColor="@android:color/black"
    app:strokeWidth="2dp">
[...]

</com.google.android.material.card.MaterialCardView>

Current result
