如何让CollapsingToolbarLayout在滚动后完全消失？

<android.support.design.widget.CollapsingToolbarLayout
    ...
    app:layout_scrollFlags="scroll|exitUntilCollapsed">
    ...
</android.support.design.widget.CollapsingToolbarLayout>

<android.support.design.widget.CollapsingToolbarLayout
    ...
    app:layout_scrollFlags="scroll|exitUntilCollapsed">

    <android.support.v4.widget.NestedScrollView
        ...
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <!-- 可滚动的内容 -->

    </android.support.v4.widget.NestedScrollView>

</android.support.design.widget.CollapsingToolbarLayout>

CollapsingToolbarLayout collapsingToolbarLayout = findViewById(R.id.collapsingToolbarLayout);
AppBarLayout appBarLayout = findViewById(R.id.appBarLayout);

appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() {
    @Override
    public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
        if (Math.abs(verticalOffset) == appBarLayout.getTotalScrollRange()) {
            // 完全折叠时隐藏CollapsingToolbarLayout
            collapsingToolbarLayout.setVisibility(View.GONE);
        } else {
            collapsingToolbarLayout.setVisibility(View.VISIBLE);
        }
    }
});
