Android 无法在 material Snackbar 上调用 setAnchorView

Question

此 Snackbar 来自包 com.google.android.material.snackbar. it extends BaseTransientBottomBar< Snackbar >，但没有 snackbar.setAnchorView 或 snackbar.anchorView。我错过了什么吗？

build.gradle

// Android
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.core:core-ktx:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'com.google.android.material:material:1.0.0'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    implementation "androidx.navigation:navigation-fragment-ktx:$nav_version"
    implementation "androidx.navigation:navigation-ui-ktx:$nav_version"

Answer 1

使用：

implementation 'com.google.android.material:material:1.1.0'

方法setAnchorView was introduced和1.1.0-alpha01.

Answer 2

"view" in "make" 方法的参数就是这样。
