我第一次使用 Jetpack Compose,但出现此错误。我还没有弄清楚问题到底出在哪里,但我正在使用单活动架构。如果需要更多信息,请告诉我。根据错误,问题似乎来自脚手架。

                val scaffoldState = rememberScaffoldState()

                Scaffold(
                    scaffoldState = scaffoldState,
                    snackbarHost = {
                        SnackbarHost(hostState = it)
                    }
                ) {

我有同样的错误并通过更新撰写版本解决了它。Android Studio生成的新项目模板自带compose版本1.0.0-beta01

打开 build.gradle 文件并更新

compose_version = '1.0.0-beta05'

或更新,如果你愿意。

androidx.navigation:navigation-compose:1.0.0-alpha10添加为依赖项后出现此错误。

对我有用的是降级到androidx.navigation:navigation-compose:1.0.0-alpha09.

这段代码我得到了同样的错误

java.lang.NoSuchFieldError: 
No static field Companion of type Landroidx/compose/foundation/layout/BoxScope$Companion; 
in class Landroidx/compose/foundation/layout/BoxScope; 
or its superclasses (declaration of 'androidx.compose.foundation.layout.BoxScope' 
appears in /data/app/ink.iamt.demo-l1DoSMoQUFGcF5KYI5RU0w==/base.apk)
class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            Card {
                Text("Hello, Compose")
            }
        }
    }
}

你知道我的代码再简单不过了。所以我认为这不应该是我的错。我检查了我的 Android Studio 版本,它是 2020.3.1 Canary 14,这是最新版本。并检查了 Jetpack compose 的 build.gradle,它是

    val compose_version by extra("1.0.0-beta01")

所以最新的 Android Studio 新建了一个 Compose 项目,compose 版本是 1.0.0-beta01,而最新的 compose 版本是 1.0.0-beta04。然后我尝试将版本更新到 beta04 并重新运行我的应用程序。然后它起作用了!

因此,请尝试将您的 compose 版本更新到最新版本,看看您是否有运气。

此答案基于帮助我修复错误的 CommonsWare 评论。

解决方案是使用一组一致的 Compose 依赖项。beta04 在 compose-foundation 工件中对 BoxScope 进行了更改。也许您正在获得该工件的 beta04,但正在获得一个较旧的 compose-material 工件。
