What is the main purpose of a ViewGroup?

The main purpose of a ViewGroup is to serve as a container for View objects, arranging them in a specified layout. ViewGroups are the building blocks of a user interface in Android applications, allowing developers to create complex layouts by organizing individual view components (such as buttons, text views, and images) in various ways.

A ViewGroup can define how its child views are positioned on the screen and can manage the layout and rendering process for its children. Examples of common ViewGroups in Android include LinearLayout, RelativeLayout, and ConstraintLayout, each providing different ways to arrange child views. This functionality is crucial for creating the overall structure of the user interface, making it visually appealing and user-friendly.

In contrast, while grouping views and making a view interactive are important aspects of user interface design, these processes don’t describe the primary role of a ViewGroup. Similarly, setting colors and background images is more about customizing individual views rather than the primary function of a ViewGroup.
