为什么 TransitionManager.beginDelayedTransition(container, sharedAxis) 不接受 sharedAxis？ [安卓]

Question

根据Material Motion Development Guide for Android，您可以通过设置以下内容让视图自动通过其共享轴进行动画处理

// Set up a new MaterialSharedAxis in the specified axis and direction.
val sharedAxis = MaterialSharedAxis(MaterialSharedAxis.Y, true)

// Begin watching for changes in the View hierarchy.
TransitionManager.beginDelayedTransition(container, sharedAxis)

// Make any changes to the hierarchy to be animated by the shared axis transition.
outgoingView.visibility = View.GONE
incomingView.visibility = View.VISIBLE

但是，当我调用 TransitionManager.beginDelayedTransition(container, sharedAxis) 时，beginDelayedTransition() 仅接受 (ViewGroup sceneRoot) 或 (ViewGroup sceneRoot, Transition transition) 作为参数，而不接受 (ViewGroup sceneRoot, MaterialSharedAxis)，如 Material.io 指南中所述。为什么会这样？

这是我的 Gradle 依赖项

build.gradle（应用程序）

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')

    // Kotlin
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.72"

    // Constraint Layout
    implementation "androidx.constraintlayout:constraintlayout:1.1.3"

    // Core
    implementation "androidx.core:core:1.3.0"

    // Material Design
    implementation "com.google.android.material:material:1.2.0-rc01"
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'

    //Navigation Component
    implementation "androidx.navigation:navigation-fragment-ktx:2.3.0"
    implementation "androidx.navigation:navigation-ui-ktx:2.3.0"
}

build.gradle（项目）

dependencies {
    classpath 'com.android.tools.build:gradle:4.0.1'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$version_kotlin"
    classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.3.0"
}

发现Android Studio自动导入了import android.transition.TransitionManager而不是import androidx.transition.TransitionManager。
