Android Google+ SignInButton. How to set size attribute in xml

Question

Here is a basic Google+ Android Sign-In button in XML:

<com.google.android.gms.common.SignInButton
    android:id="@+id/sign_in_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

In the class documentation it states that you can specify the size of the button as ICON_ONLY, STANDARD AND WIDE.

How do you do this using xml?
