片段转换在jetpack导航框架中不起作用

即使在设置了输入、退出、弹出器和弹出式转换之后,过渡也不起作用。

<fragment
    android:id="@+id/introFragment"
    android:name="IntroFragment"
    android:label="IntroFragment" >
    <action
        android:id="@+id/action_introFragment_to_signinFragment"
        app:destination="@id/signinFragment"
        app:enterAnim="@anim/slide_from_right"
        app:exitAnim="@anim/slide_to_left"
        app:popEnterAnim="@anim/slide_from_left"
        app:popExitAnim="@anim/slide_to_right"
        app:popUpTo="@+id/nav_graph" />
    <action
        android:id="@+id/action_introFragment_to_signupFragment"
        app:destination="@id/signupFragment"
        app:enterAnim="@anim/slide_from_right"
        app:exitAnim="@anim/slide_to_left"
        app:popEnterAnim="@anim/slide_from_left"
        app:popExitAnim="@anim/slide_to_right"
        app:popUpTo="@+id/nav_graph" />
</fragment>

我在用

def nav_version = "1.0.0-alpha05"
// Navigation Component - Jetpack
implementation "android.arch.navigation:navigation-fragment-ktx:$nav_version"
implementation "android.arch.navigation:navigation-ui-ktx:$nav_version"
androidTestImplementation "android.arch.navigation:navigation-testing-ktx:$nav_version"

我的导航代码是

button.setOnClickListener(
            Navigation.createNavigateOnClickListener(R.id.signinFragment))
