Re: [android-developers] Problem refreshing a fragment edittext view from a dialogFragment after rotation

setTargetFragment / getTargetFragment as per my last reply.

Also, there's 2 factors:

1- my DateTimePickerDialogFragment is being included in a different library project, so it will not know the sub type of Fragment being passed.

2- in one target fragment i will need, i have two edittexts in the same fragment so the DateTimePickerDialogFragment must somehow point to the correct edittext....

Hi al! i've read the answer from Dianne, and it seems i can declare an interface in one fragment and then implement it on another. But for this i need the pointer to the fragment in question, she said:

" take advantage of the FragmentManager APIs to save a fragment "pointer" in a bundle and later retrieve it, to allow you to maintain direct pointers across state save/restore. "

What's the best way to do this? Here's my code to call the dialogfragment in the main frag:

"dialFragment=DateTimePickerDialogFragment.newInstance(DateTimePickerDialogFragment.DATETIME_PICKER, dateBeginTV);

  dialFragment.show(fragMan, "dialog");"

how can i send the pointer to the dialogfragment, and will it survive the rotation?

Ok, I assumed that text field was part of the activity. In your case https://groups.google.com/forum/?fromgroups#!topic/android-developers/NBlMJnMaGbo should help, especially the answer of Dianne.

In short: you might just do "dialogfragment.setTargetFragment(textfieldfragment)" in the activity to link the fragments. Android will then take care of that reference. In the dialogFragment you can then pass the new value like "((MyFragmentClass)getTargetFragment()).setDateTimeField(curDateTime()).
