How to get top Fragment in backstack from DialogFragment

I'm using navigation to navigate between fragments.

And I have a DialogFragment, it can called from from many fragment like this:

 val dialog = FragmentDialog
 dialog.show(childFragmentManager, "home_fragment")

And I want to know dialogfragment called by which fragment

I tried with FragmentManager.backStackEntryCount but it's seem doesn't work

Can I have a advice for this problem ???

Solution

  • There are multiple ways to do this ..

    1. You can just Pass a key in Bundle to your DialogFragment to check which Fragment opened it ..

    2. If your Dialog fragment a attached to a fragment in each case you can just use getParentFragment() . getParentFragment() will return the instance of that fragment. If its attached to activity then getParentFragment() will be null so watch out for this case also .

    3. you can also use getTag() from where it was open byt passing different tags to transaction .
