How to keep only first added Fragment in back stack (fragment overlapping)?

Question

Scenario what i\'m trying to achieve:

1. Loading activity with two frame containers (for list of items and for details).
2. At the app launch time add listF

Answer 1

Very nice explanation by Budius. I read his advice and implemented similar navigation, which I would like to share with others.

Instead of replacing fragments like this:

Transaction.remove(detail1).add(detail2)
Transaction.remove(detail2).add(detail3)
Transaction.remove(detail3).add(detail4)

I added a fragment container layout in the activity layout file. It can be either LinearLayout, RelativeLayot or FrameLayout etc.. So in the activity on create I had this:

transaction.replace(R.id.HomeInputFragment, mainHomeFragment).commit();

mainHomeFragment is the fragment I want to get back to when pressing the back button, like infoFrag. Then, before EVERY NEXT transaction I put:

fragmentManager.popBackStackImmediate();
transaction.replace(R.id.HomeInputFragment, frag2).addToBackStack(null).commit();

or

fragmentManager.popBackStackImmediate();
transaction.replace(R.id.HomeInputFragment, frag3).addToBackStack(null).commit();

That way you don't have to keep track of which fragment is currenty showing.
