Is there an alternative to Android's ViewOverlay?

Android's ViewOverlay allows easy overlaying of Drawables over a conventional view element without having to interfere with the layout, but it is only available since API 18 (and as far as I can see, there's no compatibility layer, that backports this).

What would be the easiest alternative for an older API level (specifically: 15) to overlay a Drawable over a view element without modifying the layout? In my case, it would be enough to deal with a single Drawable; I don't need to replicate support for multiple Drawables that the new overlay API allows.

Did you try FrameLayout's foreground attribute?
FrameLayout's foreground is drawn over it's contents. And this works with API level 15.

In your xml:

<FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:foreground="@drawable/your_drawable">

    ...
    Your contents.
    ...

</FrameLayout>

Or in your source code:

frameLayout.setForeground(drawable);
