Radio buttons are an essential UI component for allowing users to select a single option from a list. In this blog post, we'll dive into how to create and work with radio buttons in Jetpack Compose, starting with the basics and moving on to more advanced use cases.

Radio buttons allow the user to select one option from a set. You should use radio buttons for optional sets that are mutually exclusive if you think that the user needs to see all available options side-by-side. If it's not necessary to show all options side-by-side, use a spinner instead.

Custom Checkbox in Jetpack Compose Here, instead of using the built-in Checkbox composable, we've used the Icon composable and handled the checked state. We've used a star icon to represent the checked state and a star outline icon for the unchecked state. Following is the complete code. Following is the output.

For this article, create an empty Jetpack Compose project and open MainActivity. Add a composable called MyUI() and call it from the onCreate() method. We will write our code in the MyUI(). selected ? Whether this radio button is selected or not.

Unfortunately, as of now, there's no direct way to adjust the size of a Checkbox in Jetpack Compose. The size of the Checkbox is determined by the default Material Design specifications. In other words, the size is fixed.

RadioButtons are used to select only a specific option from the list of several options in a list or either. Radio buttons are used in many places for selecting only one option from the list of two or more options.

We use CheckboxDefaults. colors to specify the color when the checkbox is checked (checkedColor), the color when it's not checked (uncheckedColor), and the color of the checkmark (checkmarkColor). The checked variable dictates whether the checkbox is selected or not.

While ISCHANGED() will check if the current value is different from its prior value - it will return true if the values are different. Therefore using both functions together we can check if the checkbox field has been changed and if so was it changed from true to false. If it was we show the user an error message.

If you have checkbox variable as true/false ,then you can not make mandatory. Since a checkbox only contains a true or false value, it always contains SOME value, which makes mandatory kind of useless.
