How can I get clickable hyperlinks in AlertDialog from a string resource?

Question

What I am trying to accomplish is to have clickable hyperlinks in the message text displayed by an AlertDialog. While the AlertDialog implementation happily underlines and colors any hyperlinks (defined using <a href="..."> in the string resource passed to Builder.setMessage) supplied the links do not become clickable.

The code I am currently using looks like this:

new AlertDialog.Builder(MainActivity.this).setTitle(
        R.string.Title_About).setMessage(
        getResources().getText(R.string.about))
        .setPositiveButton(android.R.string.ok, null)
        .setIcon(R.drawable.icon).show();

I'd like to avoid using a WebView to just display a text snippet.

I didn't really like the currently most popular answer because it significantly changes the formatting of the message in the dialog.

Here's a solution that will linkify your dialog text without otherwise changing the text styling:

    // Linkify the message
    final SpannableString s = new SpannableString(msg); // msg should have url to enable clicking
    Linkify.addLinks(s, Linkify.ALL);

    final AlertDialog d = new AlertDialog.Builder(activity)
        .setPositiveButton(android.R.string.ok, null)
        .setIcon(R.drawable.icon)
        .setMessage( s )
        .create();

    d.show();

    // Make the textview clickable. Must be called after show()
    ((TextView)d.findViewById(android.R.id.message)).setMovementMethod(LinkMovementMethod.getInstance());
