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
Once you’ve added a progress bar to your Android app, it’s important to test and optimize it to ensure it provides the best possible user experience.
