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

[João Rossa]

Hi! Sorry for the late reply, so i created call backs, the DialogFragment
receives an interface type that the fragment that calls the dialog must
implement, this works well if setRetainInstance is set to true, but what if
i dont want to use this property?

regards,

 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()**).

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

[Bluemercury]

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

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

[Bluemercury]

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()).

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

[Bluemercury]

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?

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

[al]

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.

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

[Bluemercury]

Hi! Seems replying directly from gmail doesnt refresh this page. so im 
posting again, i changed the property like you said but if i call the 
dialogfragment, rotate the phone and press ok, it wont refresh the 
editext.Only if i call it again, dont rotate, and press ok. The problem 
happens when i rotate with the dialogfragment being visible, if the 
edittext has any value, before i rotate, by default it will show the values 
after rotation correctly , so the issue here lies when i rotate while 
showing the dialogfragment, seems the edittext i pass to it looses the 
connection with the view layout

regards,

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

[Fred Niggle]

This is caused by the contents of the edittext not being saved when rotated.
If the edittext is defined via xml then set

 android:freezesText="true"

to stop the edittext from loosing its contents upon rotation.

Hope this help,
Fred
