In this video I’ll show you how to easily add a switch to your Kivy App.

Switches are great for toggling things on or off. To create a switch, just define it in your .kv file and set an on_active function that we can define on the python backend.

The switch will pass a switchValue when clicked that is either True or False. Then we can run a simple if statement to determine whether the switch has been switched to on or off, and take action accordingly.

Python Code:
GitHub Code:

from import App
from kivy.uix.widget import Widget
from kivy.lang import Builder

# Designate Our .kv design file 

class MyLayout(Widget):
	def switch_click(self, switchObject, switchValue):
		if (switchValue):
			self.ids.my_label.text = "You clicked the Switch On!!"
			self.ids.my_label.text = "You clicked the Switch Off!!"
			#self.ids.my_switch.disabled = True

class AwesomeApp(App):
	def build(self):
		return MyLayout()

if __name__ == '__main__':

Kivy Design Code: switch.kv
GitHub Code: switch.kv

		orientation: "vertical"
		size: root.width, root.height
			id: my_label
			font_size: 32
			text: "The Switch Is On!"

			id: my_switch
			active: True
			disabled: False
			font_size: 32
			on_active: root.switch_click(self,
