How do I create a ListView with dashed / dotted line dividers in Android?

Question

I managed to figure out how to create a custom shape (with a dashed stroke) by creating a file called dash.xml inside of the /app/res/drawable/ folder:

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="line">
    <stroke
        android:color="#534b4b"
        android:width="1dp"
        android:dashGap="2dp"
        android:dashWidth="1dp"
    />
    <size
        android:height="1dp"
    />
</shape>

Now I'm confused as to how to apply this shape to a ListView. I've tried the following, but no divider is displayed:

<ListView android:id="@+id/android:list" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:cacheColorHint="#00000000"
    android:divider="@drawable/dash"
    android:dividerHeight="1dp"
/>

Wtf?

Here is mine and it works :

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="line">
    <stroke
        android:color="#FF404040"
        android:width="1dp"
        android:dashGap="3dp"
        android:dashWidth="1dp"
    />
    <size
        android:height="3dp"
    />
</shape>
