[+ R.drawable中的imageResource导致Jetpack编写中出现IllegalArgumentException

Question

我正在使用名为HomeActivity的新的空JC活动测试Jetpack Compose。我正在尝试将可绘制资源加载到我的代码中。这是我的功能：

@Composable
fun home() {
    MaterialTheme(
        colors = colors,
        typography = typography
    ) {
        val menuIcon = +imageResource(R.drawable.ic_baseline_menu_24)
        val bottomActions = listOf<Image>()
        var (drawerState, onDrawerStateChangeListener) = +state { DrawerState.Closed }

        BottomDrawerLayout(drawerState = drawerState, onStateChange = onDrawerStateChangeListener, drawerContent = {
            Text(text = "Drawer")
        }) {
            Column(
                crossAxisSize = LayoutSize.Expand
            ) {
                BottomAppBar(
                    navigationIcon = {
                        drawerState = DrawerState.Opened
                        AppBarIcon(icon = menuIcon, onClick = {})
                    },
                    actionData = bottomActions,
                    action = {
                        AppBarIcon(icon = it, onClick = {})
                    }
                )
            }
        }
    }
}

根据JC网站，+imageResource(R.drawable.xyz)应该将资源作为andX.ui Image对象加载imageResource函数返回Effect<Image>，它不会使应用程序崩溃，但我不知道如何将其解析为AppBarIcon]所需的图像对象

某些Logcat输出：

HomeActivity.kt：66是这个val menuIcon = +imageResource(R.drawable.ic_baseline_menu_24)

Answer 1

就我而言，我解决了从ic_chat_bubble.xml(anydpi) ic_chat_bubble

Answer 2

我也遇到了同样的问题，并观察到imageFromResource()和imageResource()无法加载矢量资源。您需要通过提供资源ID来创建effectOf<VectorAsset>，并使用DrawVector()绘制矢量资产。您可以使用下面的@Composable函数绘制矢量资源。
