Switch in Navigation drawer item with Design Support Library on Android

Your menu item for the navigation drawer:

<item
    android:id="@+id/nav_item1"
    android:icon="@drawable/ic_item1"
    android:title="item1"
    app:actionLayout="@layout/layout_switch"
    />

and the layout for that item:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.SwitchCompat
        android:id="@+id/drawer_switch"
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:text=""/>

</LinearLayout>

EDIT:

I ended up using a different approach. In fact, I found out that you can use any view in the drawer, so there's no point in bothering with the menu stuff. Just create a view the usual way (with listeners, etc.) and add in to the drawer.

One way I have found of doing this would be to use setActionView on the menuItem you want:

mNavigationView.getMenu().findItem(R.id.nav_connect)
        .setActionView(new Switch(this));

// To set whether switch is on/off use:
((Switch) mNavigationView.getMenu().findItem(R.id.nav_connect).getActionView()).setChecked(true);

Probably want a click listener as well to change the state of the Switch:

mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
    @Override
    public boolean onNavigationItemSelected(MenuItem menuItem) {

        switch (menuItem.getItemId()) {
            case R.id.nav_connect:
                ((Switch) menuItem.getActionView()).toggle();
                return true;
        }
    }
}

I haven't tried, but you could probably use android:actionLayout="@layout/switch_layout" in xml and point to a custom layout you created.

Also could try using an ActionProvider which might offer a little more robustness. I haven't tried this method either though.
