java.lang.ClassNotFoundException：找不到类“ android.view.View $ OnUnhandledKeyEventListener”

Question

我在android的xml布局文件中使用了android support v7 recyclerView

      <android.support.v7.widget.RecyclerView
            android:id="@+id/messagelist"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="3"
            android:clipToPadding="false"
            android:scrollbars="vertical" />

我切换到androidx，所以我将回收站视图更改为androidx recyclerView，如下所示：

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/messagelist"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="3"
            android:clipToPadding="false"
            android:scrollbars="vertical" />

所以我收到此错误：

    Caused by: java.lang.ClassNotFoundException: Didn't find class "android.view.View$OnUnhandledKeyEventListener" on path: DexPathList[[zip file "/data/app/com.yassineghr.chatdemov2-2/base.apk"],nativeLibraryDirectories=[/data/app/com.yassineghr.chatdemov2-2/lib/x86, /system/lib, /vendor/lib]]

这是我的gradle构建文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.2"
    defaultConfig {
        applicationId "com.yassineghr.chatdemov2"
        minSdkVersion 21
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    configurations.all {
        resolutionStrategy.eachDependency { DependencyResolveDetails details ->
            def requested = details.requested
            if (requested.group == "androidx") {
                if (!requested.name.startsWith("multidex")) {
                    details.useVersion "${targetSdk}.+"
                }
            }
        }
    }

}
