我已将 RecycleView 添加到我的 XML 中,如下所示:
<androidx.recyclerview
android:id="@+id/recycleViewTest"
android:layout_width="match_parent"
android:layout_height="match_parent" />
我在 build.gradle 中的依赖项定义如下:
dependencies
{
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.google.android.material:material:1.0.0-alpha1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
implementation "androidx.recyclerview:recyclerview:1.0.0-alpha1"
}
项目已编译,但是在运行它时崩溃,并且出现以下异常:
Caused by: android.view.InflateException: Binary XML file line #9: Binary XML file line #9: Error inflating class androidx.recyclerview
Caused by: android.view.InflateException: Binary XML file line #9: Error inflating class androidx.recyclerview
Caused by: java.lang.ClassNotFoundException: Didn't find class "androidx.recyclerview" on path: DexPathList[[zip file "/data/app/
我的 compileSdkVersion 设置为 28 。有什么建议吗?
更新:
我添加了依赖项:
implementation 'com.android.support:recyclerview-v7:28.0.0-beta01'
所以我的依赖项现在看起来像这样:
dependencies
{
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.google.android.material:material:1.0.0-alpha1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
implementation 'com.android.support:recyclerview-v7:28.0.0-beta01'
}
但是现在我遇到了一个新错误:
Manifest merger failed : Attribute application@appComponentFactory value=(androidx.core.app.CoreComponentFactory) from [androidx.core:core:1.0.0-alpha1] AndroidManifest.xml:22:18-86
is also present at [com.android.support:support-compat:28.0.0-beta01] AndroidManifest.xml:22:18-91 value=(android.support.v4.app.CoreComponentFactory).
Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:6:5-21:19 to override.
所以我添加了以下属性:
tools:replace="android:appComponentFactory"
对于 application 标签,如下所示:
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
tools:replace="android:appComponentFactory"
android:theme="@style/AppTheme">
但是现在我又遇到另一个错误:
Manifest merger failed with multiple errors, see logs

androidx.recyclerview是一个软件包名称,您需要一个View的package + classname通过XML对其进行充气,我在寻找您,但androidx.recyclerview软件包现在具有视图。
如果您打算使用RecyclerView(https://developer.android.com/guide/topics/ui/layout/recyclerview)
正确的gradle语句是:
implementation 'com.android.support:recyclerview-v7:27.1.1'
,XML标记为:
android.support.v7.widget.RecyclerView

如果您切换到AndroidX,则需要更改
android.useAndroidX = true
和android.enableJetifier = true
一致,对于之前确实属于支持库的所有部分。 您不能将支持库与androidx混合使用,否则清单合并会像您一样抱怨。
要特别切换RecycleView,请更改
implementation 'androidx.recyclerview:recyclerview:1.0.0'
的依赖androidx.recyclerview.widget.RecyclerView
映射可以在“迁移到AndroidX”指南here中找到。
