The menu generated by the system by default is a default view implementation, which can only add menu items and cannot customize the layout.
You need to delete the menu.xml generated by the system, create a new layout file in the layout directory, and replace it with your own view layout.

Then includeyour own layout
已省略部分代码

<android.support.v4.widget.DrawerLayout>

    //侧滑菜单主框架
    <include
        layout="@layout/app_bar_nav"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
    //菜单部分
    <LinearLayout
        android:layout_width="@dimen/nav_width"
        android:layout_height="match_parent"
        android:background="@color/black"
        android:orientation="vertical"
        android:layout_gravity="start">

        //头部头像部分
        <include
            layout="@layout/nav_header_nav"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1"/>

        //你自定义的菜单布局，具体里面你随意实现你自己需要的内容
        <include
            layout="@layout/nav_menu"
            android:layout_width="match_parent"
            android:layout_weight="3"
            android:layout_height="0dp"
            />
    </LinearLayout>
</android.support.v4.widget.DrawerLayout>

I am a picture ↓

The xml of the menu is responsible for the content

style is managed by the view that displays the menu, such as NavigationView's android.support.design:itemTextAppearance
