Here is an example:

 

from kivy.lang import Builder
from kivy.properties import StringProperty

from kivymd.app import MDApp
from kivymd.uix.list import IRightBodyTouch, OneLineAvatarIconListItem
from kivymd.uix.selectioncontrol import MDCheckbox
from kivymd.icon_definitions import md_icons


KV = '''
<ListItemWithCheckbox>:
    IconLeftWidget:
        icon: root.icon
    RightCheckbox:
        id: cb          # crate an id to address the checkbox

MDBoxLayout:
    orientation: 'vertical'
    ScrollView:
        MDList:
            id: scroll
    MDBoxLayout:
        size_hint_y: None
        height: dp(48)
        Button:
            text: 'Set CheckBoxes'
            on_release: app.set_checkboxes(True)
        Button:
            text: 'Clear CheckBoxes'
            on_release: app.set_checkboxes(False)
        Button:
            text: 'Set Item 5'
            on_release: app.set_one_checkbox('Item 5', True)
'''


class ListItemWithCheckbox(OneLineAvatarIconListItem):
    '''Custom list item.'''
    icon = StringProperty("android")


class RightCheckbox(IRightBodyTouch, MDCheckbox):
    '''Custom right container.'''
    pass


class MainApp(MDApp):
    def build(self):
        return Builder.load_string(KV)

    def on_start(self):
        icons = list(md_icons.keys())
        for i in range(30):
            self.root.ids.scroll.add_widget(
                ListItemWithCheckbox(text=f"Item {i}", icon=icons[i])
            )

    def set_checkboxes(self, v):  # pass True to set, false to clear
        # the children of scroll are the ListItemWithCheckBoxWidgets
        for w in self.root.ids.scroll.children:
            w.ids.cb.active = v

    def set_one_checkbox(self, s, v):
        # pass a string to identify a checkbox and value to set
        for w in self.root.ids.scroll.children:
            if w.text == s:
                w.ids.cb.active = v
                break




MainApp().run()
