Question

I have a FragmentActivity support v4 class which implements two side by side (kind of like gmail) fragments and a button which can bring up a DialogFragment.

This all works great unless I have an orientation change. When I have an orientation change the states of the Fragments are not saved.

And the main problem is if I have a the FragmentDialog open, it simply disappears.

I have set setRetainInstance(true); in all fragments but it did not help.

In my manifest I included android:configChanges="orientation" but is still does not help.

Here are my code samples, thank you for the help.

public class AddMasterDialog extends DialogFragment {

    private int mTitle;
    private int mPrompt;
    private OnClickListener onSaveListener;
    private OnClickListener onCancelListener;

    public AddMasterDialog newInstance(int title, int prompt) {
        AddMasterDialog simpleDialog = new AddMasterDialog(title, prompt);
        return simpleDialog;
    }

    public AddMasterDialog() {
        // Empty constructor required for DialogFragment
    }
    public AddMasterDialog(int title, int prompt) {
        // Empty constructor required for DialogFragment
        mTitle = title;
        mPrompt = prompt;
    }
    public void setSaveButton(OnClickListener save){
        onSaveListener = save;
    }
    public void setCancelButton(OnClickListener cancel){
        onCancelListener = cancel;
    }
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setRetainInstance(true);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        //if(savedInstanceState == null){
            View view = inflater.inflate(R.layout.add_new_simple, container);
            getDialog().setTitle(mTitle);
            ((TextView) view.findViewById(R.id.add_simple_new_value_prompt)).setText(mPrompt);

            Button saveButton = (Button) view.findViewById(R.id.add_simple_save_button);
            saveButton.setOnClickListener(onSaveListener);

            //Cancel Button
            Button cancelButton = (Button) view.findViewById(R.id.add_simple_cancel_button);
            cancelButton.setOnClickListener(onCancelListener);
            return view;
        //}
    }
}

and in my Main activity:

private void initiateAddMasterPopupWindow() {
        try {
            addMasterDialog = new AddMasterDialog(R.string.add_new_master_dialog_title, R.string.add_master_new_value_prompt);
            addMasterDialog.setSaveButton(saveNewMasterClickListener);
            addMasterDialog.setCancelButton(cancelNewMasterClickListener);
            FragmentManager fm = getSupportFragmentManager();
            addMasterDialog.show(fm, ADD_NEW_MASTER);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Okay, so the issue seems to be with the DialogFragment compatibility library.

The issue was described in this post.

“An obsolete DISMISS message for the fragment is retained in the message queue. It’s been queued by DialogFragment.onDestroyView() when dismissing the old dialog and gets reactivated after creating the new dialog.

A quick (and possibly dirty) workaround is to override onDestroyView() and clear the dismiss listener before calling super.onDestroyView()“

Adding the following code to my DialogFragment solved the issue:

 @Override
 public void onDestroyView() {
     if (getDialog() != null && getRetainInstance()) {
         getDialog().setDismissMessage(null);
     }
     super.onDestroyView();
 }
