Creating of dialog. It's method from my custom DialogFragment.

public Dialog onCreateDialog(Bundle savedInstanceState) {
        String title = getArguments().getString(KEY_TITLE, getString(R.string.dg_dp_title));
        LocalDate date = (LocalDate) getArguments().getSerializable(KEY_DATE);
        if (null == date) date = new LocalDate();
        FragmentActivity context = getActivity();
        @SuppressLint("InflateParams")
        View view = LayoutInflater.from(context).inflate(R.layout.dialog_date_picker, null);
        mDatePickerView = (DatePicker) view.findViewById(R.id.dg_dp_picker);
        mDatePickerView.updateDate(date.getYear(), date.getMonthOfYear() - 1, date.getDayOfMonth());
        return new AppDialogBuilder(context)
                .setTitle(title)
                .setView(view)
                .setPositiveButton(R.string.dg_dp_button_positive, mListener)
                .setNegativeButton(R.string.dg_dp_button_negative, mListener)
                .create();
    }

Layout file.

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://ift.tt/nIICcg"
             android:layout_width="match_parent"
             android:layout_height="match_parent">

    <DatePicker
        android:id="@+id/dg_dp_picker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:calendarViewShown="true"
        android:datePickerMode="calendar"
        android:spinnersShown="false"/>
</FrameLayout>

If remove setting title form builder, then dialog will looks fine

But I need to use title. Thoughts?
