属性工厂附件未找到

Question

我在使用材质组件时无法运行项目.

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'android.arch.lifecycle:extensions:1.1.1'

    implementation 'com.facebook.fresco:fresco:1.11.0'
    implementation 'com.theartofdev.edmodo:android-image-cropper:2.7.+'
    implementation  'com.fxn769:pix:1.2.5'




    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.android.support:cardview-v7:28.0.0'
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:support-v4:28.0.0'

}

看起来这个属性已在androidx中删除.要附加操作栏,只需将属性app:layout_anchor添加到您的工厂.

<com.google.android.material.floatingactionbutton.FloatingActionButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="16dp"
        app:fabSize="normal"
        android:src="@drawable/ic_add_white_24dp"
        app:layout_anchor="@id/bottom_app_bar"/>
