BottomSheetBehavior不在androidX库中 [英] BottomSheetBehavior not in androidX libraries

问题描述

我在原始支持库中使用了BottomSheetBehavior:

I was using the BottomSheetBehavior with the original support library:

implementation 'com.android.support:design:27.1.1' 

尽管缺少BottomSheetBehavior，但我迁移使用新的androidx库时.上述支持库中的映射不在 AndroidX重构列表中要么，但是迁移工具将其删除.

When I migrated to use the new androidx libraries though the BottomSheetBehavior is missing. The mapping from the above support library isn't in the AndroidX Refactoring List either, but the migration tool removed it.

将BottomSheetBehavior包含在新的androidx库中，我缺少什么.

What am I missing to include the BottomSheetBehavior with the new androidx libraries.

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.google.android.material:material:1.0.0-beta01'
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"

    // ReactiveX
    implementation 'io.reactivex.rxjava2:rxandroid:2.0.2'
    implementation 'io.reactivex.rxjava2:rxkotlin:2.2.0'

    implementation 'com.android.support:design:28.1.0'

    // Android Compatability Libraries
    // Version: https://developer.android.com/topic/libraries/support-library/refactor
    implementation 'androidx.appcompat:appcompat:1.0.0-beta01'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha1'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0-beta01'
    implementation 'androidx.lifecycle:lifecycle-extensions:2.0.0-beta01'
    implementation 'androidx.recyclerview:recyclerview:1.0.0-beta01'

    // Android Navigation Component
    // Check here for updated version info - will move to androidx soon.
    // https://developer.android.com/topic/libraries/architecture/adding-components
    def nav_version = "1.0.0-alpha04"

    // use -ktx for Kotlin
    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"

    // Testing
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.0-alpha4'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha4'
}

推荐答案

事实证明，Android Studio Refactor > Migrate to AndroidX中的重构工具未正确迁移BottomSheetBehaviour的XML.

It turns out that the refactor tool in Android Studio Refactor > Migrate to AndroidX didn't correctly migrate the XML for the BottomSheetBehaviour.

旧位置为android.support.design.widget.BottomSheetBehavior，并且未由迁移工具修改.原始XML是:

The old location was android.support.design.widget.BottomSheetBehavior, and was not modified by the migration tool. The original XML was:

<fragment
    android:id="@+id/player_bottom_sheet_fragment"
    android:name="app.rxsongbrowsertrials.ui.player.PlayerToggleFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:behavior_hideable="false"
    app:behavior_peekHeight="56dp"
    app:layout_behavior="android.support.design.widget.BottomSheetBehavior"
    />

新位置为com.google.android.material.bottomsheet.BottomSheetBehavior，因此布局需要变为:

The new location is com.google.android.material.bottomsheet.BottomSheetBehavior, so the layout needs to become:

<fragment
    android:id="@+id/player_bottom_sheet_fragment"
    android:name="app.rxsongbrowsertrials.ui.player.PlayerToggleFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:behavior_hideable="false"
    app:behavior_peekHeight="56dp"
    app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior"
    />
