要开始使用 Compose，您需要先向项目中添加一些 build 配置。将以下定义添加到应用的 build.gradle 或者build.gradle.kts 文件中：

build.gradle

android {buildFeatures {compose true}composeOptions {kotlinCompilerExtensionVersion = "1.5.9"}kotlinOptions {jvmTarget = "19"}
}

build.gradle.kts

android {buildFeatures {compose = true}composeOptions {kotlinCompilerExtensionVersion = "1.5.9"}kotlinOptions {jvmTarget = "19"}
}

需要注意以下几点：

• 在 Android BuildFeatures 代码块内将 compose 标志设置为 true 会启用 Compose 功能。
• ComposeOptions 代码块中定义的 Kotlin 编译器扩展版本控制与 Kotlin 版本控制相关联。请务必参阅兼容性对应图，并选择与您项目的 Kotlin 版本匹配的库版本。

此外，请将以下部分中您需要的 Compose BoM 和 Compose 库依赖项的子集添加到您的依赖项：

build.gradle

dependencies {def composeBom = platform('androidx.compose:compose-bom:2024.02.00')implementation composeBomandroidTestImplementation composeBom// Choose one of the following:// Material Design 3implementation 'androidx.compose.material3:material3'// or Material Design 2implementation 'androidx.compose.material:material'// or skip Material Design and build directly on top of foundational componentsimplementation 'androidx.compose.foundation:foundation'// or only import the main APIs for the underlying toolkit systems,// such as input and measurement/layoutimplementation 'androidx.compose.ui:ui'// Android Studio Preview supportimplementation 'androidx.compose.ui:ui-tooling-preview'debugImplementation 'androidx.compose.ui:ui-tooling'// UI TestsandroidTestImplementation 'androidx.compose.ui:ui-test-junit4'debugImplementation 'androidx.compose.ui:ui-test-manifest'// Optional - Included automatically by material, only add when you need// the icons but not the material library (e.g. when using Material3 or a// custom design system based on Foundation)implementation 'androidx.compose.material:material-icons-core'// Optional - Add full set of material iconsimplementation 'androidx.compose.material:material-icons-extended'// Optional - Add window size utilsimplementation 'androidx.compose.material3:material3-window-size-class'// Optional - Integration with activitiesimplementation 'androidx.activity:activity-compose:1.8.2'// Optional - Integration with ViewModelsimplementation 'androidx.lifecycle:lifecycle-viewmodel-compose:2.6.1'// Optional - Integration with LiveDataimplementation 'androidx.compose.runtime:runtime-livedata'// Optional - Integration with RxJavaimplementation 'androidx.compose.runtime:runtime-rxjava2'}

build.gradle.kts

注意：Jetpack Compose 使用物料清单 (BoM) 提供，以确保所有库组的版本保持同步。如需了解详情，请参阅“物料清单”页面。
