How do I 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
<a href="some site">Link text</a>
.

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.

Answer

Buried in the API demos I found the solution to my problem:

Link.java:

    // text2 has links specified by putting <a> tags in the string
    // resource.  By default these links will appear but not
    // respond to user input.  To make them active, you need to
    // call setMovementMethod() on the TextView object.

    TextView t2 = (TextView) findViewById(R.id.text2);
    t2.setMovementMethod(LinkMovementMethod.getInstance());

I removed most of the attributes on my TextView to match what was in the demo.

<TextView
    android:id="@+id/text2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/txtCredits"/>

That solved it. Pretty difficult to uncover and fix.
