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()). Am Dienstag, 5.
