Screen Rotation
Author: Scott Pierce
A simple Composable to manually rotate the screen with Jetpack Compose, without rotating the Activity.
| @Composable | |
| fun RotateScreen( | |
| rotation: ScreenRotation, | |
| modifier: Modifier = Modifier, | |
| contentAlignment: Alignment = Alignment.TopStart, | |
| content: @Composable () -> Unit | |
| ) { | |
| BoxWithConstraints { | |
| val width: Dp | |
| val height: Dp | |
| when (rotation) { | |
| ScreenRotation.LEFT_90_DEGREES, ScreenRotation.RIGHT_90_DEGREES -> { | |
| width = maxHeight | |
| height = maxWidth | |
| } | |
| else -> { | |
| width = maxWidth | |
| height = maxHeight | |
| } | |
| } | |
| Box( | |
| modifier = modifier | |
| .rotate(rotation.degrees) | |
| .width(width) | |
| .height(height), | |
| contentAlignment = contentAlignment | |
| ) { | |
| content() | |
| } | |
| } | |
| } | |
| enum class ScreenRotation(val degrees: Float) { | |
| LEFT_90_DEGREES(-90f), RIGHT_90_DEGREES(90f), NORMAL(0f) | |
| } |
