Jetpack Compose is a modern toolkit for building Android UIs. If you’re working on an app that requires a scrollable column, you’re in luck! In this guide, we’ll walk you through the steps to create a scrollable column using Jetpack Compose.
Set up Android project with Compose.
Before you can create a scrollable column in Jetpack Compose, you’ll need to set up your project and import the necessary dependencies. create a new project with compose template
Create a Column and add your content.
To create a column in Jetpack Compose, use the Column() compose function and add your content inside it. For example, if you want to display a list of items, you can create a Column and add a Text() element for each item. To make the column scrollable, wrap it in a ScrollableColumn() function.
This will add scrolling functionality to your column. With these simple steps, you can easily create a scrollable column in your Jetpack Compose app.
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.padding
import androidx.compose.runtime.Composable
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp
@Composable
fun ScrollableColumnExample() {
Column(
modifier = Modifier
.padding(16.dp)
) {
// Add content here
}
}
Wrap your Column in a Scrollable modifier
To create a scrollable column in Jetpack Compose, you need to wrap your Column in a Scrollable modifier. This modifier allows you to add scrolling functionality to your column.
To do this, simply add the Scrollable modifier to your Column and specify the scrolling direction using the verticalScroll() or horizontalScroll() parameter. You can also customize the scrolling behavior by adding additional parameters, such as reverseScrollDirection or isScrollEnabled. With these simple steps, you can easily create a scrollable column in your Jetpack Compose app.
@Composable
fun ScrollableColumnExample() {
Column(
modifier = Modifier
.padding(16.dp)
.verticalScroll(rememberScrollState())
) {
Text(text = "Privacy Policy ", fontWeight = FontWeight.Bold, fontSize = 24.sp)
Text(text = stringResource(id = R.string.lorem_ipsum))
Text(text = stringResource(id = R.string.lorem_ipsum))
Text(text = stringResource(id = R.string.lorem_ipsum))
Text(text = stringResource(id = R.string.lorem_ipsum))
}
}
Customize your scroll behavior with additional modifiers
In addition to the basic scrolling functionality provided by the Scrollable modifier, you can also customize the scrolling behavior using additional modifiers. For example, you can use the snapToOffsets() modifier to create a snap-to-grid effect, where the column snaps to specific offsets as the user scrolls.
You can also use the nestedScroll() modifier to enable nested scrolling within your column, allowing users to scroll both horizontally and vertically within a single column. By experimenting with these additional modifiers, you can create a truly customized scrolling experience for your users.
Available option
fun Modifier.verticalScroll(
state: ScrollState,
enabled: Boolean = true,
flingBehavior: FlingBehavior? = null,
reverseScrolling: Boolean = false
) = scroll(
state = state,
isScrollable = enabled,
reverseScrolling = reverseScrolling,
flingBehavior = flingBehavior,
isVertical = true
)
Test and adjust as needed
As with any development process, it’s important to test your scrollable column and make adjustments as needed. Test your column on different devices and screen sizes to ensure that it works properly and looks good. You may also want to gather feedback from users to see if there are any improvements or changes that could be made. By continuously testing and adjusting your scrollable column, you can create a seamless and enjoyable user experience.

) {
Text(text = "Privacy Policy ", fontWeight = FontWeight.Bold, fontSize = 24.sp)
Text(text = stringResource(id = R.string.lorem_ipsum))
Text(text = stringResource(id = R.string.lorem_ipsum))
Text(text = stringResource(id = R.string.lorem_ipsum))
Text(text = stringResource(id = R.string.lorem_ipsum))
}
}
