                    .setClickListener(new Link.OnClickListener() {
                        @Override
                        public void onClick(String text) {
                            // do something
                        }
                    });

// match string "string"
Link linkAnd = new Link("string")
                    .setTextColor(Color.BLUE)
                    .setTextStyle(TextStyle.BOLD_ITALIC)
                    .setClickListener(new Link.OnClickListener() {
                        @Override
                        public void onClick(String text) {

List<Link> links = new ArrayList<>();
