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

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());

If you are only showing some text and URL[s] in your dialog perhaps the solution is simpler

public static class MyOtherAlertDialog {

 public static AlertDialog create(Context context) {
  final TextView message = new TextView(context);
  // i.e.: R.string.dialog_message =>
            // "Test this dialog following the link to dtmilano.blogspot.com"
  final SpannableString s = 
               new SpannableString(context.getText(R.string.dialog_message));
  Linkify.addLinks(s, Linkify.WEB_URLS);
  message.setText(s);
  message.setMovementMethod(LinkMovementMethod.getInstance());

  return new AlertDialog.Builder(context)
   .setTitle(R.string.dialog_title)
   .setCancelable(true)
   .setIcon(android.R.drawable.ic_dialog_info)
   .setPositiveButton(R.string.dialog_action_dismiss, null)
   .setView(message)
   .create();
 }
}

This should make <a href> tags to get highlighted as well. Please note that i have just added a few lines to emmby's code. so credit to him

final AlertDialog d = new AlertDialog.Builder(this)
 .setPositiveButton(android.R.string.ok, null)
 .setIcon(R.drawable.icon)
 .setMessage(Html.fromHtml("<a href=\"http://www.google.com\">Check this link out</a>"))
 .create();
d.show();
// Make the textview clickable. Must be called after show()   
    ((TextView)d.findViewById(android.R.id.message)).setMovementMethod(LinkMovementMethod.getInstance());
