NavigationView gives you attr app:headerLayout for adding header for navigation. For adding footer just wrap the desired footer view in your NavigationView,

<RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    >

    <LinearLayout
        android:background="@android:color/darker_gray"
        android:clickable="true"
        android:id="@+id/ll_header"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:orientation="vertical">

        <TextView
            android:gravity="center"
            android:id="@+id/nav_header_textview"
            android:layout_height="48dp"
            android:layout_width="match_parent"
            android:text="Your Header Text Here" />

    </LinearLayout>

    <android.support.design.widget.NavigationView
        android:layout_below="@+id/ll_header"
        android:layout_above="@+id/ll_footer"
        android:id="@+id/navigation"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        app:menu="@menu/my_navigation_items" >


    </android.support.design.widget.NavigationView>

    <LinearLayout
        android:id="@+id/ll_footer"
        android:background="@android:color/darker_gray"
        android:layout_alignParentBottom="true"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:orientation="vertical">

        <TextView
            android:gravity="center"
            android:id="@+id/nav_footer_textview"
            android:layout_height="48dp"
            android:layout_width="match_parent"
            android:text="Your Footer Text Here" />

    </LinearLayout>

</RelativeLayout>

for example purpose,I have used TextView.
