I am designing UX for an activity feed on a mobile app. The height of each feed/activity item will vary, and should include actions like share, like, etc. The straight-forward approach for implementing these actions would be an action bar at the bottom of each feed item. However, I am considering to earn some more real estate (as well as add some gestural quality) by enclosing these actions in a swipe gesture, e.g.:
This works well when applied to lists that are made up of list-items of fixed height. However, since the height of activity items on my feed will vary, I am wondering if this is a good idea?
