android - Full width Navigation Drawer

Question

I'd like to create a full width navigation drawer. Setting layout_width to match_parent on @+id/left_drawer yields in width of about 80% of screen space. This seems to be the standard behavior. Do I have to override onMeasure() of DrawerLayout?

My current code:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/black"
        android:id="@+id/mainFragmentContainer">
    </FrameLayout>

    <include
        android:id="@+id/left_drawer"
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        layout="@layout/drawer"/>
</android.support.v4.widget.DrawerLayout>

Thanks.

If you want simpler solution you can just set negative margin

android:layout_marginLeft="-64dp"

for your left_drawer:

<include
        android:id="@+id/left_drawer"
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        layout="@layout/drawer"
        android:layout_marginLeft="-64dp"/>
