Virtual keyboard in kivy

Request Keyboard

The configuration is in charge of the virtual keyboard's instantiation. In the Configuration object, look for keyboard mode and keyboard layout.

If you want to make a widget that needs a keyboard, you should use the best way available on the platform rather than the virtual keyboard. In the Window, look at the request_keyboard() method.

You should write like this  (from 1.8.0, numeric.json can be in the same directory in which main.py is)when you want custom layout when you request the keyboard :

keyboard = Window.request_keyboard(
    self._keyboard_close, self)
if keyboard.widget:
    vkeyboard = self._keyboard.widget
    vkeyboard.layout = 'numeric.json'

Basic Approach:
1) import kivy
2) import kivyApp
3) import vkeyboard
4) set kivy version (optional)
5) Create the Vkeyboard class
6) Create the App class
7) return the vkeyboard class
8) Run the App

Implementation of the Approach

Now we'll look at a sample python application code that uses Kivy to show how the approach described above for vkeyboard works.
.py file

# to import kivy module
import kivy
    
# this is to restrict the kivy version i.e
# below this kivy version we cannot
# use the app
kivy.require("1.9.1")
    
# app:always used to refer to your application's instance
from kivy.app import App
 
# VKeyboard is an onscreen keyboard
# for Kivy. Its operation is intended
# to be transparent to the user.
from kivy.uix.vkeyboard import VKeyboard
 
# to create the vkeyboard
class Test(VKeyboard):
    user = VKeyboard()
 
# Create the App class
class VkeyboardKivyApp(App):
    def build(self):
        return Test()
 
# run the App
if __name__ == '__main__':
    VkeyboardKivyApp().run()

Frequently Asked Question

Is Kivy suitable for mobile apps?

Kivy is a great option if you want people to be able to access your mobile app on multiple devices while maintaining a consistent appearance and feel.

Is Kivy free?

Kivy is a free and open-source Python framework for developing mobile apps and application software with a natural user interface (NUI).

In Kivy, what is a canvas?

The Canvas is the root object that a Widget can use to draw on. By default, every Widget in Kivy has a Canvas. You may create all of the drawing instructions while constructing a widget.

What is a float layout in Kivy?

Float layout groups widgets with proportional coordinates with the size_hint and pos_hint attributes. The values are numbers ranging from 0 to 1, showing a proportional relationship to the window size.
