androidandroid-fragmentsback-stack

Going from 3rd to 1st fragment in the backstack: Android

I have a sequence of event via which i have added three fragments to the backstack, one by one. Each of these fragments covers the full screen of the activity.

I have stored the is returned from the commit of Frag1.

Now in Frag3, based on a specific click, I want to go back to Frag1 directly and discard/pop all Fragments in between.

So, when this button is clicked i send a message to the activity which does the following:

getSupportFragmentManager().popBackStack(mFrag1Id, FragmentManager.POP_BACK_STACK_INCLUSIVE);

But i just got a blank screen, so i assume no fragment was loaded.

I even tried: In commit - fragmentTransaction.addToBackStack("Fragment1"); and then 

getSupportFragmentManager().popBackStack("Fragment1", FragmentManager.POP_BACK_STACK_INCLUSIVE);

But it doesn't work. Could someone please help me with this?

Thanks.

Solution

  • OK so I found the issue.

    FragmentManager.POP_BACK_STACK_INCLUSIVE pops all the fragments including the one whose id passed as argument.

    SO for example:

    getSupportFragmentManager().popBackStack(mFrag1Id, FragmentManager.POP_BACK_STACK_INCLUSIVE);

    Here it will pop everything on the stack including fragment whose id id mFrag1Id.
