Introduction: The Problem of System Keyboards in Android Jetpack Compose

In the world of Android development, particularly with Jetpack Compose, UI customization is key to delivering an engaging user experience. One common challenge developers face is the need to hide the system keyboard when a TextField is focused. Instead, developers often prefer to provide their own custom keyboard tailored to the specific needs of their application. In this guide, we'll explore a straightforward solution to this problem, ensuring that you can offer a unique input method while keeping user experience at the forefront.

Understanding the Challenge

When users tap on a TextField, Android by default opens the system keyboard. However, there are scenarios where this is not desirable. You might want to:

Enhance user experience by providing a custom keyboard that fits the style of your app.

Control input more accurately by restricting certain inputs or providing additional features.

Many developers have tried various methods to suppress the system keyboard, such as using getWindow().setSoftInputMode(), but often these solutions fall short or don't behave as expected.

The Solution: Hiding the System Keyboard with Jetpack Compose

Fortunately, there’s a simple and effective way to hide the system keyboard in Jetpack Compose using the CompositionLocalProvider functionality. Below are the steps to follow:

Step-by-Step Implementation

1. Use CompositionLocalProvider

To hide the system keyboard and use your own custom keyboard, implement the following code snippet when defining your focusable TextField:

2. Explanation of the Code

CompositionLocalProvider: This is a provider that allows you to provide a new value for a CompositionLocal for the duration of its block. In our case, it provides a null value for LocalTextInputService.

LocalTextInputService: This is a CompositionLocal that controls the text input service (keyboard) in Jetpack Compose. By providing null, you effectively inform Jetpack Compose that no system keyboard should be shown.

3. Implementing Your Custom Keyboard

After removing the system keyboard, it's time to implement your own custom keyboard. Here are a few tips to create a seamless experience:

Design an intuitive layout that reflects the functionality needed for your app's context.

Handle user input effectively by binding the custom keyboard's actions to the focused TextField.

Provide visual feedback to users to enhance engagement.

Conclusion: Enjoy Custom Input Experiences in Your App

By employing the approach of using CompositionLocalProvider to hide the system keyboard, you can now freely design and implement your own custom keyboard in Jetpack Compose. This not only improves the aesthetics of your application but also enhances the overall user experience. Remember, a well-thought-out input method can set your application apart in a crowded marketplace, so take advantage of this opportunity to innovate on how users interact with your app.

Implement the solution described above today and enjoy the flexibility of a custom input experience in your Android applications!
