How to get username/display name in Buddypress?

buddypress, php, wordpress

Solution

You have Display name use below function:

bp_get_displayed_user_fullname()

OR

Display User Name:

bp_core_get_username($user_id)

Problem

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.
