Understand the importance of a progress indicator
A progress indicator is an essential component of any app that performs time-consuming tasks. It helps users understand that the app is working on a task and not frozen, which can improve the overall user experience. Without a progress indicator, users may become frustrated and assume that the app is not working correctly. Adding a progress indicator can also help reduce user anxiety and increase their confidence in the app’s performance
Choose the right type of progress indicator for your app
When adding a progress indicator to your Android app, it’s important to choose the right type for your specific use case.
Types of progress indicators in Compose
Mainly two types of progress indicators are available in Jetpack Compose UI
- LinearProgressIndicator
- CircularProgressIndicator
Implement the Progress Indicator Compose UI
What Option is available in LinearProgressIndicator
@Composable
fun LinearProgressIndicator(
modifier: Modifier = Modifier,
color: Color = MaterialTheme.colors.primary,
backgroundColor: Color = color.copy(alpha = IndicatorBackgroundOpacity)
)
How to use LinearProgressIndicator
LinearProgressIndicator()
FloatRange(from = 0.0, to = 1.0)
LinearProgressIndicator(0.6f)
How to use CircularProgressIndicator
CircularProgressIndicator()
FloatRange(from = 0.0, to = 1.0)
CircularProgressIndicator(0.8f)
Customize the progress indicator on the Android
You can change the colors and progress value, The floating range min value 0.0 and max values can be 1.0.
LinearProgressIndicator(
0.6f, color = Color.Red,
)
CircularProgressIndicator customized the color and stroke width like below.
CircularProgressIndicator(
color = Color.Red, progress = 0.8f, strokeWidth = 8.dp
)
Test and optimize the progress indicator
