How to make links in a TextView clickable?

I have the following TextView defined:

<TextView android:layout_width="wrap_content"
    android:layout_height="wrap_content" android:text="@string/txtCredits"
    android:autoLink="web" android:id="@+id/infoTxtCredits"
    android:layout_centerInParent="true"
    android:linksClickable="true"></TextView>

where @string/txtCredits is a string resource that contains Link text.

Android is highlighting the links in the TextView, but they do not respond to clicks. Can someone tell me what I'm doing wrong? Do I have to set an onClickListener for the TextView in my activity for something as simple as this?

Looks like it has to do with the way I define my string resource. This does not work:

<string name="txtCredits"><a href="http://www.google.com">Google</a></string>

But this does:

<string name="txtCredits">www.google.com</string>

Which is a bummer because I would much rather show a text link than show the full URL.
