android - How to make Seek bar in Slide menu?

Question

I'm a student making an application using an android studio for practice. I want to make seek bar in basic slide menu, which android studio provides as navigation drawer. I searched about it but couldn't find it. If the answer already exists, I apologise. Pretty hard to search by English...

Is there a way to create seek bar in slide menu so users can edit the value? For instance, users can control size or opacity of pen directly by editing the value of seek bar in slide menu. I made an example image. Thanks for reading.

Modify your NavigationView to accommodate android Views instead of menu.So that you can customize the entire Navigation Drawer Menu.

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <include layout="@layout/nav_header_main" />

        <ListView
            android:id="@+id/lst_menu_items"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:entries="@array/sports_array"
            android:layout_weight="1" />

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