How to center action menu on toolbar

I have an application with a split action bar loading an action menu.

I changed the actionbar for the new toolbar and replaced the split actionbar by an other toolbar used in standalone mode : 

Toolbar toolbarBottom = (Toolbar) findViewById(R.id.toolbarBottom);
toolbarBottom.inflateMenu(R.menu.ab_one_cam);

As specified in the documentation the action menu is pin to the right of the toolbar : enter image description here

But i would like the icons to be centered on the toolbar , like it was on the split actionbar : enter image description here

How can i make the action menu take all the available space on the toolbar ?

The toolbar is dedicated to this menu , nothing else will be added on it.

Answer

The accepted answer's link lead to a split toolbar. If like me you have very simple need this code is good enough : 

public class SplitToolbar extends Toolbar {

    public SplitToolbar(Context context) {
        super(context);
    }

    public SplitToolbar(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public SplitToolbar(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public void addView(View child, ViewGroup.LayoutParams params) {
        if (child instanceof ActionMenuView) {
            params.width = LayoutParams.MATCH_PARENT;
        }
        super.addView(child, params);
    }
}

In this case, Chris Banes recommends to use ActionMenuView instead of Toolbar (see the link below, reply #6). Besides that, in this link you can find a solution where the guy subclassed Toolbar in order to the split works right.

Hope it helps you!

I've also been trying to find an answer to this question the past couple weeks. And the closest thing I have found takes advantage of the fact that the Toolbar is just a ViewGroup. All you need to do is create a menu_items layout that is just a LinearLayout with equally weighted menu items added. I know this isn't an ideal solution but I haven't found anyway to spread out the items while using the default menu.

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar_btm"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:minHeight="?attr/actionBarSize"
        android:background="@color/toolbar_bkgnd"
        android:layout_alignParentBottom="true"
        app:theme="@style/ThemeOverlay.AppCompat.ActionBar" >

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

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