Android RadioButton Function Explained

In Android, a RadioButton is a type of user interface widget typically used to allow users to select a single option from multiple choices. RadioButtons are commonly utilized with a RadioGroup to ensure that only one RadioButton can be selected within the same group.

The main functions include:

1. Single selection feature: The RadioButton allows users to choose a single option from a group of choices. When a user selects one RadioButton, the others will automatically be deselected.
2. RadioButton is typically used in forms or settings interfaces to allow users to select one option from different choices.
3. Visual feedback: When a user selects a RadioButton, its state changes (such as being displayed as selected), providing visual feedback to the user.

By using RadioButtons, developers can easily achieve the single selection function and provide users with an intuitive interface for making choices.
