How to get username/display name in Buddypress?

问题:

In buddypress default tempalte, username who has posted a certain activity is displayed like this: bp_activity_action(); But that brings much more than just the username. Is there a simpler way to get the user object/name ?

Wordpess get userdata function doesn't work, as it displays the page author, not the comment or activity author name.
