We can determine the width and height of a screen using the LocalConfiguration and Constraints API provided by Jetpack Compose.
To get the width and height, we can use the following code:
@Composable
fun ScreenSize() {
val configuration = LocalConfiguration.current
val screenWidthDp = configuration.screenWidthDp.dp
val screenHeightDp = configuration.screenHeightDp.dp
val constraints = Constraints(
minWidth = screenWidthDp,
maxWidth = screenWidthDp,
minHeight = screenHeightDp,
maxHeight = screenHeightDp
)
// Use the constraints to set the size of the Composable
}
In this code snippet, we first get the current LocalConfiguration, which contains information about the current screen size in density-independent pixels (dp). We then convert the screen width and height to dps and use them to create a Constraints object that limits the size of a Composable to the full size of the screen.
We can then use this constraints object to set the size of a Composable. For example, we can use it in a Box to create a Composable that fills the entire screen:
@Composable
fun FullScreenContent() {
Box(
modifier = Modifier.fillMaxSize(),
contentAlignment = Alignment.Center
) {
// Content that fills the entire screen
}
}
