One common technique to enhance user experience is by incorporating loading spinners, which signal to users that their request is being processed. With the advent of Jetpack Compose, creating elegant loading spinners in Android apps has become even more streamlined and efficient.
In this tutorial, we’ll dive into the realm of Android Jetpack Compose to craft a visually appealing Jetpack Compose Loading Spinner that seamlessly integrates into your app’s UI.
What is Jetpack Compose?
Jetpack Compose is a modern toolkit for building native Android UIs. It simplifies and accelerates UI development through a declarative approach, allowing developers to describe the desired UI state and letting Compose handle the rest. With Compose, UI components are composed using Kotlin functions, offering greater flexibility and ease of use compared to traditional XML-based layouts.
Getting Started
Before we proceed, ensure that you have the latest version of Android Studio installed, along with the necessary dependencies for Jetpack Compose.
Implementation
Let’s start by creating a new Composable function for our loading spinner:
@Composable
fun LoadingSpinner() {
Box(
contentAlignment = Alignment.Center,
modifier = Modifier.fillMaxSize()
) {
CircularProgressIndicator(
color = Color.Blue, // Customize color as needed
strokeWidth = 4.dp // Adjust thickness
)
}
}
In the above code, we define a LoadingSpinner function that utilizes Jetpack Compose’s CircularProgressIndicator to create the loading animation. We wrap it in a Box composable to center it within the parent layout.

Other properties of CircularProgressIndicator are as follows:
@Composable
fun CircularProgressIndicator(
modifier: Modifier = Modifier,
color: Color = ProgressIndicatorDefaults.circularColor,
strokeWidth: Dp = ProgressIndicatorDefaults.CircularStrokeWidth,
trackColor: Color = ProgressIndicatorDefaults.circularTrackColor,
strokeCap: StrokeCap = ProgressIndicatorDefaults.CircularIndeterminateStrokeCap,
)Integration
To integrate the loading spinner into your app, simply call the LoadingSpinner function within your UI hierarchy:
@Composable
fun MyApp() {
Column(
modifier = Modifier.fillMaxSize(),
verticalArrangement = Arrangement.Center,
horizontalAlignment = Alignment.CenterHorizontally
) {
Text(text = "Welcome to MyApp")
LoadingSpinner() // Display loading spinner
}
}
Conclusion
In this tutorial, we explored how to create a loading spinner using Jetpack Compose in Android. By leveraging Compose’s declarative syntax, we were able to quickly and efficiently build a visually appealing loading animation that enhances the user experience of our app.
Feel free to customize the loading spinner further by adjusting its color, size, or animation properties to better suit your app’s design aesthetics.
