DialogFragment callback on orientation change

Question

I\'m migrating my dialogs, currently using Activity.showDialog(DIALOG_ID);, to use the DialogFragment system as discussed in the android reference.

Answer 1

There is better solution instead of using static methods and variables because it would work only fro one instance of your dialog. It is better to store your callback as non static member

private DialogTestListener mListener;
public void setListener (DialogTestListener listener){
  mListener = listener;
}

Then you should show your dialog using TAG like this mDialogFragment.show(getSupportFragmentManager(), DIALOG_TAG);

And then in onResume method of your activity you can reset your listener

protected void onResume() {
   super.onResume();
   mDialogFragment = (CMFilterDialogFrg) getSupportFragmentManager().findFragmentByTag(DIALOG_TAG);
   if(mDialogFragment  != null){
       mDialogFragment.setListener(yourListener)
   }
}
