How to adjust 2 toolbars to fit parent width

Question

I have 2 Toolbars in the code below and I want to see them side by side. first should cover 80% of the width and remaining should be covered by the second toolbar. How can I do that. I can hard code the width like 200dip /100 dip but that does not work when I change mobile.. Screen bursts.

<android.support.design.widget.AppBarLayout
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:theme="@style/AppTheme.AppBarOverlay"
        android:layout_weight="1"
        >

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="0dip"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay"
            android:layout_gravity="top|left"
            android:layout_weight="0.8"/>



    </android.support.design.widget.AppBarLayout>
    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar1"
        android:layout_width="0dip"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay"
        android:layout_gravity="top|right"
        android:layout_weight="0.2"/>
