Get “android:layout_height” from `AttributeSet` in a custom view constructor

There seems to be alot of "similar" questions and answers to this scattered around which all refer to how to get a custom attribute from an AttributeSet. What I haven't been able to find so far is how to get an android namespace tag:

    <com.custom.view.StatusThumbnail        android:id="@+id/statusThumbnailContainer"        android:layout_width="0dp"        android:layout_height="wrap_content"        android:layout_margin="5dp"        android:layout_weight="1"/>

I would like to pull back the "layout_height" attribute from this custom component. Unfortunately from what I've read the closest I've got to how to do this is:

public StatusThumbnail(Context context, AttributeSet attrs) {    super(context, attrs);    String height = attrs.getAttributeValue("android", "layout_height");

But this returns null.

Surely this isn't a rare thing to try and do?
