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());
