Creating Dynamic Menus with Jetpack Compose

Kotlin and Jetpack Compose stand at the forefront of modern Android application development. Today, I’ll show you how to create an interactive and visually appealing menu structure using this powerful combination.

Basic Structure of the Project

Our project contains a main activity named MainActivity, which extends from the ComponentActivity class. On app launch, this activity sets up our user interface with the setContent method.

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            CircularMenuGroupTheme {
                MainMenuCanvas()
            }
        }
    }
}

Menu Design

Our @Composable function, MainMenuCanvas, defines the visual design and behavior of the menu. The main menu is designed as a central circle with sub-menu buttons around it. These sub-menus open and close with an animated effect.

@Composable
fun MainMenuCanvas() {
    // Menu items and animations are defined here
}

Dynamic and Colorful Circles

One of the most striking features of the menu is that each sub-menu item has different color gradients. Kotlin’s Random function dynamically generates these colors.

User Interaction

The menu responds to touch inputs. When the main circle is tapped, the sub-menus open, and each sub-menu item can be moved by dragging.

Conclusion

This project demonstrates the flexibility of Jetpack Compose and the power of Kotlin. Interactive menus are crucial elements that enrich the user experience in a modern application. This example opens the doors to creating visually attractive and practical interfaces with Jetpack Compose.
