Compose Runtime 找不到我的自定义主题

Cha*_*har 8 android android-jetpack android-jetpack-compose

尝试玩弄Jetpack Compose并陷入第一个活动本身。

我的应用程序在启动时崩溃，但出现以下异常：

这是我的活动代码（:app模块）：

class LocationActivity : ComponentActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        setContent {
            Screen()
        }
    }

    @Composable
    fun Screen() {

            Column(
                verticalArrangement = Arrangement.Center
            ) {
                PinCodeField()
            }
        }
    }

    @Composable

这是我的主题ChanseTheme.kt（:commonui模块）

我的颜色出现在ChanseColors.kt（:commonui模块）中

上述依赖关系存在于:commonui模块中，api并且整个模块用作:app模块中的依赖关系。

这里可能会出现什么问题？任何帮助，将不胜感激。

导致此问题的原因是您:commonui没有build.gradle以适合 jetpack 撰写的方式配置文件：

android {
   
    buildFeatures {
        compose true
    }
    
    composeOptions {
        kotlinCompilerVersion = kotlin_version
        kotlinCompilerExtensionVersion = compose_version
    }
   
    
    kotlinOptions {
        jvmTarget = '1.8'
        useIR = true
    }
}

尝试配置一下:commonui以这种方式配置所有遍历模块，它应该可以工作。

遍历模块：

例如你有下一个模块图 -> :commonui-> A -> module_which_has_a_problem在这种情况下，你必须以A相同的方式配置模块

我相信这是一个错误。有时，当我在真实设备上运行预览时，我会遇到同样的错误。所以我建议：

确保您正在运行活动而不是预览（检查运行按钮旁边选定的运行配置）
尝试在模拟器上运行

根据我的经验，Compose 工具目前相当不稳定。准备好做一些事情，例如使缓存无效、替换撰写版本以强制某种重置等。
