Hi,
I found the code to hide comments in the activity stream. Adds an additional button (show / hide comments)
How can I add the number of comments for the current post?

I have something like that made by @shay1383

add_action( 'wp_footer', 'add_comment_hide_show' );
function add_comment_hide_show() {
    ?>
    <style>
        .activity-comments ul li[id^="acomment-"]{display: none;}
    </style>
    <script type="text/javascript">
        jQuery(function($) {
            setInterval(function() {
                $('.activity-meta').each(function() {
                    if( !$(this).find('.show-comments').length ){
                        var html = '<a href="#" class="button bp-primary-action show-comments">Show/Hide Comments</a>';
                        $(this).find('.button.acomment-reply').after(html);
                    }
                });

            }, 500);

            $('body').on('click', '.show-comments', function(e) {
                e.preventDefault();
                var obj = $(this).closest('.activity-content').next('.activity-comments').find('ul li[id^="acomment-"]');
                obj.slideToggle();
                return false;
            });

        });
    </script>
    <?php
}

For comments button, the number of commentators is displayed by:
<a href="<?php bp_activity_comment_link(); ?>" class="button acomment-reply bp-primary-action" id="acomment-comment-<?php bp_activity_id(); ?>"><?php printf( __( 'Comment %s', 'buddypress' ), '<span>' . bp_activity_get_comment_count() . '</span>' ); ?></a>

But if I use it, the same number of comments appear under each post. How to make it work?
