title: Android: How to swipe between activities (not fragments), master/detail best set-up
body: <p>I'm working on an android app and I'm fairly new to all this, including mobile app development, so I have a few questions. Any help would be amazing!</p>
  
  <p>1) Is it possible to swipe between entire activities (including action bar)?
      And I don't mean like viewPager swapping between fragments, I mean swapping the 
      entire screen (like snapchat does on iOS). Is this possible at all? And if so, 
      how can I do this?</p>
  
  <p>2) What is the best way to implement a master/detail type layout? Like twitter 
  for instance, if i have a listView of the tweets, and when a person clicks on a 
  tweet it takes you to a detailed view of that specific tweet... What would be the 
  best way to accomplish this? Would I have an activity with a list view and create 
  a second activity upon clicking on a tweet? Or would I use fragments instead, one 
  for the list view and one for the detailed view? </p>
  
  <p>3) Is there a way to have different action bars for every fragment?</p>
  
  <p>Thank you so very much!!!</p>
