android - Jetpack Compose Bottom Sheet 初始化错误

Question

在 Jetpack compose 1.0.0-beta01 中，我这样调用 BottomSheetScaffold:

BottomSheetScaffold(
    scaffoldState = bottomSheetScaffoldState,
    sheetContent = { Text("") },
    sheetShape = Shapes.large,
    backgroundColor = AppTheme.colors.uiBackground,
    modifier = modifier
    
) { (content) }

...并得到以下错误:

java.lang.IllegalArgumentException: The initial value must have an associated anchor.

有关解决此问题的任何提示？

Answer 1

不要忘记添加以下属性:

sheetPeekHeight = 0.dp

所以你的代码应该是这样的:

BottomSheetScaffold(
    scaffoldState = bottomSheetScaffoldState,
    sheetContent = { Text("") },
    sheetShape = Shapes.large,
    sheetPeekHeight = 0.dp, // <--- new line
    backgroundColor = AppTheme.colors.uiBackground,
    modifier = modifier
    
) { (content) }
