KivyMD: BottomAppBar { Alternate Menu } | (Python Mobile-Desktop App)

KivyMD is a Python framework that is used for developing cross-platform mobile and desktop applications. It is built on top of the Kivy framework and provides a set of Material Design components that can be used to create beautiful and responsive user interfaces.

One of the components provided by KivyMD is the BottomAppBar, which is a type of material design navigation bar that can be used to display menu options at the bottom of the screen. In this tutorial, we will go through the process of creating a BottomAppBar with alternative menu options in a Python mobile-desktop app using KivyMD.

Before we begin, make sure you have KivyMD installed in your Python environment. You can install it using pip by running the following command in your terminal:

pip install kivymd

Once you have KivyMD installed, you can start creating your Python mobile-desktop app with a BottomAppBar.

Step 1: Import the necessary modules

Start by importing the required modules from KivyMD and Kivy. Open your Python file and add the following import statements:

from kivy.lang import Builder
from kivy.uix.boxlayout import BoxLayout
from kivymd.app import MDApp
from kivymd.uix.bottomappbar import MDBottomAppBar

Step 2: Create the app layout

Next, define the layout for your app. In this example, we will create a simple BoxLayout with a Button that will toggle the visibility of the BottomAppBar menu options. Add the following code to your Python file:

KV = '''
BoxLayout:
    orientation: 'vertical'

    MDBottomAppBar:
        id: bottom_app_bar
        md_bg_color: app.theme_cls.primary_color
        on_action_button: app.toggle_menu()

        MDToolbar:
            title: 'BottomAppBar'
            icon: 'menu'

        MDBottomAppBarItem:
            name: 'settings'
            icon: 'settings'
            text: 'Settings'

        MDBottomAppBarItem:
            name: 'home'
            icon: 'home'
            text: 'Home'
'''

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

    def toggle_menu(self):
        bottom_app_bar = self.root.ids.bottom_app_bar
        bottom_app_bar.set_menu()

Step 3: Run the app

Finally, initialize and run your app by adding the following lines to your Python file:

if __name__ == '__main__':
    MainApp().run()

When you run your app, you should see a BottomAppBar with alternative menu options at the bottom of the screen. Clicking the menu icon will toggle the visibility of the menu options.

In this tutorial, we covered the basics of creating a BottomAppBar with alternative menu options in a Python mobile-desktop app using KivyMD. You can customize the appearance and behavior of the BottomAppBar and its menu options by exploring the various properties and methods provided by the KivyMD framework. Happy coding!
