I think you can't. But you can "format" a string as you like:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="button_text">Add item</string>
    <string name="message_text">You don't have any items yet! Add one by pressing the %1$s button.</string>
</resources>

In the code:

Resources res = getResources();
String text = String.format(res.getString(R.string.message_text),
                            res.getString(R.string.button_text));
