Fullscreen navigation drawer

Question

I have a navigation drawer like this.

What I want to do is open my drawer to fullscreen not half screen. How do I make this drawer to open as full screen?

This is xml of drawerlayout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

<include
    android:id="@+id/toolbar_layout"
    layout="@layout/app_toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

<android.support.v4.widget.DrawerLayout
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@id/toolbar_layout"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <FrameLayout
        android:id="@+id/activityMainContent"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="@color/colorPrimary"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"

You have to put your DrawerLayout as a main layout in your xml like this:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@id/toolbar_layout"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

<include
    android:id="@+id/toolbar_layout"
    layout="@layout/app_toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

    <FrameLayout
        android:id="@+id/activityMainContent"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="@color/colorPrimary"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"
        app:itemTextColor="@android:color/white"
        app:menu="@menu/activity_main_drawer" />

</RelativeLayout>

</android.support.v4.widget.DrawerLayout>
