android - 迁移到 Jetpack/AndroidX 后的 InflateException

Question

通过 Android Studio 迁移到 Jetpack，尝试运行应用程序但在应用程序关闭时继续获取以下跟踪信息:

Caused by: android.view.InflateException: Binary XML file line #11: Error inflating class com.google.android.material.floatingactionbutton.FloatingActionButton

这是 xml:

<com.google.android.material.floatingactionbutton.FloatingActionButton
    android:id="@+id/fab"
    style="@style/Widget.MaterialComponents.FloatingActionButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|right"
    android:layout_marginRight="10px"
    android:layout_marginBottom="200px"
    android:src="@drawable/ic_plus"
    android:tint="#FFF"
    app:fabSize="mini" />

这是我的依赖项:

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'androidx.appcompat:appcompat:1.1.0-alpha03'
    implementation 'com.google.android.material:material:1.1.0-alpha04'

    implementation 'androidx.recyclerview:recyclerview:1.1.0-alpha03'
    implementation 'androidx.cardview:cardview:1.0.0'

    def lifecycle_version = '2.1.0-alpha03'

    // ViewModel and LiveData
    implementation "androidx.lifecycle:lifecycle-extensions:$lifecycle_version"
    implementation 'com.google.maps.android:android-maps-utils:0.5+'
    implementation 'com.shawnlin:number-picker:2.4.8'
}

我在示例项目中尝试了您的 XML。有用。但是你的主题应该从 Theme.MaterialComponents.blabla....

扩展

喜欢这个xml block

    <style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
