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

Hi al! The thing is here im using  framents, the text field is on the fragment, not on the activity itself. The ideia was to create a dynamic dialofgragment without to mess around with the activity too much, since in this case the fragment is part of a viewpager in the activity. What if i use the   this.setRetainInstance(true);  on the fragment that holds the text field too?

regards,

Of course I'm guessing, but I think you should change the way you transfer the new date/time value to the text widget.

In the activity, say A1, you create the dialog and give it a reference to the text field of A1. When the device is rotated, the activity is recreated (=> A2), but the dialog is not (due to this.setRetainInstance(true);). I.e. the dialog still references the text field of A1, but you see the activity A2. That's probably the cause of the observed behavior. As far as I understand it, the way to go is to add a "setDateTimeField()" method to the activity and to replace the code in the onClick method of the dialog with something like "((MyActivityClass)getActivity()).setDateTimeField(curDateTime()). GetActivity() will return the current/correct activity since the dialog will be attached to new activity as part of the configuration change.
