app 模块下的 build.gradle 添加：

   buildFeatures {compose = true}

    composeOptions {kotlinCompilerExtensionVersion = "1.4.3"}

引用入 compose 组件库：

val compose_version = "1.6.2"
implementation("androidx.compose.ui:ui:$compose_version")
implementation("androidx.compose.material:material:$compose_version")
implementation("androidx.compose.ui:ui-tooling-preview:$compose_version")
debugImplementation("androidx.compose.ui:ui-tooling:$compose_version")
implementation ("androidx.activity:activity-compose:$compose_version")
