如何禁用可组合函数的横向模式?我想始终以纵向模式显示可组合项。
PS:无法在活动的清单文件中设置它,因为我只希望此行为适用于一个可组合项,而不适用于活动中的其他可组合项。

您可以使用DisposableEffect
+ Activity来做到这一点requestedOrientation
。
@Composable
fun LockScreenOrientation(orientation: Int) {
val context = LocalContext.current
DisposableEffect(Unit) {
val activity = context.findActivity() ?: return@DisposableEffect onDispose {}
val originalOrientation = activity.requestedOrientation
activity.requestedOrientation = orientation
onDispose {
// restore original orientation when view disappears
activity.requestedOrientation = originalOrientation
}
}
}
fun Context.findActivity(): Activity? = when (this) {
is Activity -> this
is ContextWrapper -> baseContext.findActivity()
else -> null
}

用法:
@Composable
fun Screen() {
LockScreenOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE)
}
