DialogFragment.getDialog returns null

Question

I am trying to get the Dialog I have created with an extended DialogFragment using DialogFragment.getDialog() but it returns null.

Answer 1

public class Dialog extends DialogFragment {

private DialogListener dialogListener;


public void setDialogListener(DialogListener dialogListener) {
    this.dialogListener = dialogListener;
}


@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    view = inflater.inflate(R.layout.layout_dialog, null);
    return view;
}

@Override
public void onDismiss(DialogInterface dialog) {
    super.onDismiss(dialog);
    if (null != dialogListener) {
        dialogListener.onDismiss();
    }
}

public interface DialogListener {
    void onDismiss();
}

}

in Activity ...

  Dialog  dialog= new Dialog();
        dialog.setDialogListener(new Dialog.DialogListener() {
            @Override
            public void onDismiss() {
                Foo()..
            }
        });
