TextInput Form to Python Kivy

Welcome to part 8 of our Python Kivy app development series in Bangla! In this tutorial, we will learn how to create a TextInput form in Python Kivy for Android development.

Setting up the TextInput Form

First, let’s create a new Python file for our Kivy app. We will define a TextInput widget in our Kivy language file and then bind it to Python code to handle user input.

Creating the TextInput widget

In your Kivy language file, add the following code to create a TextInput widget:

<TextInput:
    id: text_input
    multiline: False
    hint_text: 'Enter your text here'
    size_hint: (0.8, 0.2)
    pos_hint: {'center_x': 0.5, 'center_y': 0.5}

Handling user input in Python

In your Python file, you can now bind the TextInput widget to a function that handles user input:

from kivy.uix.textinput import TextInput

class MyTextInput(TextInput):
    def on_text_validate(self):
        text = self.text
        # Do something with the user input

Testing the TextInput Form

Now that we have set up the TextInput form, we can run our Kivy app on an Android device to test it out. Run the following command to build and install the app on an Android device:

buildozer android debug deploy run

Once the app is installed, you should see the TextInput form on the screen. You can enter text into the form and press “Done” on the keyboard to trigger the on_text_validate function in Python.

Conclusion

Creating a TextInput form in Python Kivy for Android development is a simple and effective way to gather user input in your app. In this tutorial, we learned how to set up the TextInput widget and handle user input in Python. Stay tuned for more tutorials in our Python Kivy app development series!
