Create Android MenuItem with subtitles programmatically

Question

I need to have DrawerMenu with programmatically generated elements, I can add menuItems, but only with a title and icon, I want them to also have subtitles (as in the picture)

I get Drawer by its identifier, then by its menu and then add MenuItems as follows (code snippet from my MainActivity):

int id =0;
String MenuTitle = "Title of the item in menu";
NavigationView mDrawerList = (NavigationView)findViewByID(R.id.nav_view);
Menu menu = mDrawerList.getMenu();
MenuItem menuItem;
menuItem = menu.add (Menu.NONE, id, Menu.NONE, title);
menuItem.setIcon(R.drawable.ic_action_home);
menuItem.setCheckable(true);

Answer 1

It currently does not allow subTitle menus to be added to it. NavigationView

But if you want to achieve this, I would recommend that you take the ListViewnested inside NavigationView. . So that you can customize your ListView cell, you need to.

<android.support.design.widget.NavigationView
    android:id="@+id/navigation"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:fitsSystemWindows="true">

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

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

        <ListView
            android:id="@+id/lst_menu_items"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1" />
    </LinearLayout>
</android.support.design.widget.NavigationView>

. app: NavigationView, ListView . ListView .
