Toolbar is inside an AppBarLayout which is probably inside your CoordinatorLayout then something like this should work.

AppBarLayout appBarLayout = (AppBarLayout)findViewById(R.id.appBar);
        appBarLayout.setExpanded(true, true);

Or to collapse toolbar then something like this should work

AppBarLayout appBarLayout = (AppBarLayout)findViewById(R.id.appBar);
        appBarLayout.setExpanded(false, true);

you need this app:layout_behavior="@string/appbar_scrolling_view_behavior" in your scroll view ase below:

 <android.support.v7.widget.RecyclerView
    android:id="@+id/rvToDoList"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

we need to define an association between the AppBarLayout and the View that will be scrolled. Add an app:layout_behavior to a RecyclerView or any other View capable of nested scrolling such as NestedScrollView. The support library contains a special string resource @string/appbar_scrolling_view_behavior that maps to AppBarLayout.ScrollingViewBehavior, which is used to notify the AppBarLayout when scroll events occur on this particular view. The behavior must be established on the view that triggers the event.
