​
Overview

MainActivity is the primary activity component that serves as the entry point for the Voice to Text Android application. It extends ComponentActivity and sets up the app’s UI using Jetpack Compose.

​
Class definition

class MainActivity : ComponentActivity()

​
Methods

​
onCreate

Initializes the activity and sets up the Compose UI hierarchy. 
override fun onCreate(savedInstanceState: Bundle?)
​
savedInstanceState
Bundle?
Contains the activity’s previously saved state, or null if this is a newly created activity.

​
Implementation details

The onCreate method performs the following operations:
  1. Edge-to-edge display - Enables edge-to-edge rendering for a modern, immersive UI experience
  2. Theme application - Wraps the UI in VoiceTotextTheme for consistent Material Design styling
  3. Scaffold setup - Uses Material 3 Scaffold with a top app bar and content area
  4. Content composition - Renders the VoiceRecognitionScreen with appropriate padding
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    enableEdgeToEdge()
    setContent {
        VoiceTotextTheme {
            Scaffold(
                modifier = Modifier.fillMaxSize(),
                topBar = { AppBar() }) { innerPadding ->
                VoiceRecognitionScreen(
                    modifier = Modifier.padding(innerPadding)
                )
            }
        }
    }
}
The enableEdgeToEdge() function call ensures that your app’s content extends behind system bars for a modern, immersive experience.
