I have a main activity with a RelativeLayout container where i load different fragments using the FragmentManager . Let's say i load fragment1 and fragment2 with two transactions. In case of back button pressed, i want to return to the state when both fragment1 and fragment2 were not loaded. Is this possible? I've tried to use the same name in the addToBackStack() method:
mFragmentManager.beginTransaction().replace(R.id.activity_main, fragment1).addToBackStack("SameState").commit();
mFragmentManager.beginTransaction().add(R.id.activity_main, fragment2).addToBackStack("SameState").commit();
but this doesn't work. If i press the back button fragment2 disappears first, then pressing again fragment1 goes away too. Any suggestion?
Try this:
mFragmentManager.beginTransaction()
.replace(R.id.activity_main,fragment1)
.addToBackStack(null)
.commit();
getSupportFragmentManager().popBackStack(); // Pop the first transaction
mFragmentManager.beginTransaction()
.replace(R.id.activity_main,fragment2)
.addToBackStack(null)
.commit();
At this point, when you press the back button, it will simply revert the last transaction (fragment2 replacing).
