Access Toolbar (and its children) from fragment?

Question

I'm building an application using the v7.widget.Toolbar component.

I'm able to add the toolbar to my activity, but I don't know how (and what is the right way?) to access it from the activity's fragment.

Here's the toolbar

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
app:theme="@style/MainActionBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
tools:context=".MainActivity">

<ImageView
    android:background="@drawable/icon_1"
    android:paddingLeft="1dp"
    android:paddingRight="1dp"
    android:layout_marginLeft="19dp"
    android:id="@+id/menu_1"
    android:layout_gravity="center_vertical|left"
    android:src="@drawable/menu_burger"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

<ImageView
    android:layout_marginRight="19dp"
    android:paddingLeft="1dp"
    android:paddingRight="1dp"
    android:id="@+id/menu_2"
    android:layout_gravity="center_vertical|right"
    android:src="@drawable/icon_2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

Here's how I use it in the activity:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <include layout="@layout/view_home_toolbar" />

    <FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
     ...
     ...

</LinearLayout>

In my activity's onCreate:

   Toolbar actionBar = (Toolbar) findViewById(R.id.toolbar);
   setSupportActionBar(actionBar);

And now, for example, I want to access "@id/menu_1" from the Toolbar in my fragment, How do I do that?

getSupportActionBar() gives me the ActionBar, but I need the Toolbar

Thanks in advance!

I'm not sure if this works, but you can try it.

    final AppCompatActivity act = (AppCompatActivity) getActivity();
    if (act.getSupportActionBar() != null) {
        Toolbar toolbar = (Toolbar) act.getSupportActionBar().getCustomView();
    }

Toolbar is essentially a ViewGroup.
