Re: How to ged rid of the ”view” (or ”show”) button – Or: How to alter the Activity Header
Wow great! It worked!!! Thank you soooooooooooo much 
For everyone with the same problem: The Files are:
bp-activity-templatetags.php
entry.php
just search the for the div (e.g. firebug) to find the respective functions name in the entry.php. Then you search the function in the bp-activity-templatetags.php and change it the way you want
