Regex to get positive number

I have a string that contains a number in between and I want to get all the numbers from that string for that I have this regex ( \d+ ) but it's not serving the purpose.

I also want to include those that are mentioned in red square, what changed do I need to make in the regex.

Edit: Relevant code

String regex = "( \\d+ )";
        Pattern p = Pattern.compile(regex, Pattern.CASE_INSENSITIVE);
        Matcher m = p.matcher(textView.getText());

        while (m.find()) {
            String number = m.group().replace(" ", "");
            WAAFILogger.d("Number-regex", ":"+number+":");
            int startIndex = messageText.indexOf(number);
            int endIndex = startIndex + number.length() - 1;

            builder.setSpan(message.getSpannableListenerForNumber(number),
                    startIndex,
                    endIndex + 1,
                    Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

            textView.setMovementMethod(LinkMovementMethod.getInstance());

        }
