似乎还没有针对此的过滤器，但您可以取消注册默认活动小部件，并注册（在您的函数中，或者更好地在Dave Warfel推荐的插件中）具有自定义设置的类似活动小部件：

// unregister the default activity widget
add_action(\'wp_dashboard_setup\', \'remove_dashboard_widgets\' );
function remove_dashboard_widgets() {

    global $wp_meta_boxes;
    unset($wp_meta_boxes[\'dashboard\'][\'normal\'][\'core\'][\'dashboard_activity\']);

}

// register your custom activity widget
add_action(\'wp_dashboard_setup\', \'add_custom_dashboard_activity\' );
function add_custom_dashboard_activity() {
    wp_add_dashboard_widget(\'custom_dashboard_activity\', \'Activity\', \'custom_wp_dashboard_site_activity\');
}

function custom_wp_dashboard_site_activity() {

    echo \'<div id="activity-widget">\';

    $future_posts = wp_dashboard_recent_posts( array(
        \'display\' => 2,
        \'max\'     => 5,
        \'status\'  => \'future\',
        \'order\'   => \'ASC\',
        \'title\'   => __( \'Publishing Soon\' ),
        \'id\'      => \'future-posts\',
    ) );

    $recent_posts = wp_dashboard_recent_posts( array(
        \'display\' => 2,
        \'max\'     => 5,
        \'status\'  => \'publish\',
        \'order\'   => \'DESC\',
        \'title\'   => __( \'Recently Published\' ),
        \'id\'      => \'published-posts\',
    ) );

    $recent_comments = wp_dashboard_recent_comments( 10 );

    if ( !$future_posts && !$recent_posts && !$recent_comments ) {
        echo \'<div class="no-activity">\';
        echo \'<p class="smiley"></p>\';
        echo \'<p>\' . __( \'No activity yet!\' ) . \'</p>\';
        echo \'</div>\';
    }

    echo \'</div>\';

}
