How to hide toolbar in a fragment?

Question

I have a Main toolbar for the app... and as usual a fragment pager... but in one of my fragments I have a CollapsingToolbar as well. So,

how do I hide the main toolbar and the fragment pager toolbar when I collapse this toolbar?

XML CODE

<android.support.design.widget.AppBarLayout
    android:id="@+id/app_bar_layout"
