ViewPager + ABS + Fragments and Activities

view story

http://stackoverflow.com – I currently have an app that will be using ABS along with Jakes ViewPager Library. I currently have three tabs each of which is its own SherlockFragment or SherlockListFragment these are all hosted by one SherlockActivity. If one of my fragments needs to create a new view to take some user input and perform some processing what is the best method of doing this. Should I create a new activity, and if so is the only way of doing this to trigger the new activity from the base activity of my fragments. This seems messy since all the base fragments would have to pass calls to add new activiti (HowTos)
