The toolbar is like any other view. You can add children to it directly and access then like you would for a normal view.

This is not the exact the answer to your question, but it will tell you the way to go.

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar   xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:background="@android:color/holo_red_light"
    android:elevation="2dp"
    android:theme="@style/Base.ThemeOverlay.AppCompat.Dark">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/ic_launcher"
            android:id="@+id/button1"/>

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/ic_launcher"
            android:id="@+id/button2"/>

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/ic_launcher"
            android:id="@+id/button3"/>

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/ic_launcher"
            android:id="@+id/button4" />

    </LinearLayout>

</android.support.v7.widget.Toolbar>

Then in your main fragment or where ever else you can access something like this.

    Toolbar mToolbar = (Toolbar) root.findViewById(R.id.tool_bar);

    Button button1 = (Button) mToolbar.findViewById(R.id.button1);
    Button button2 = (Button) mToolbar.findViewById(R.id.button2);
    Button button3 = (Button) mToolbar.findViewById(R.id.button3);
    Button button4 = (Button) mToolbar.findViewById(R.id.button4);

You can use this method to make a custom toolbar any way you like. You will probably want to use a relative layout.
