build.gradle文件

apply plugin: 'com.android.application'
    
    android { 
        compileSdkVersion 28  //版本较高，用androidx开头的合适，之前在别的项目拷贝了一个android开头的依赖，哪里的sdk设置的版本都较低
        buildToolsVersion "29.0.2"//版本较高
        defaultConfig { 
            applicationId "com.example"
            minSdkVersion 19       // 应用程序支持api的下限
            targetSdkVersion 28
            versionCode 1
            versionName "1.0"
            testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        }
        buildTypes { 
            release { 
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            }
        }
    }
    dependencies { 
        implementation fileTree(dir: 'libs', include: ['*.jar'])
        //    RecyclerView 依赖库,(我出现这个问题是因为这个版本与上面sdk设置不兼容，现在的这个为兼容依赖)
        implementation 'androidx.recyclerview:recyclerview:1.0.0-alpha1'
        implementation 'androidx.appcompat:appcompat:1.0.2'
        implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
        implementation 'com.google.android.material:material:1.0.0'
        implementation 'androidx.legacy:legacy-support-v4:1.0.0'
        implementation 'androidx.navigation:navigation-fragment:2.0.0'
        implementation 'androidx.navigation:navigation-ui:2.0.0'
        implementation 'androidx.lifecycle:lifecycle-extensions:2.0.0'
        testImplementation 'junit:junit:4.12'
        androidTestImplementation 'androidx.test.ext:junit:1.1.0'
        androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
    
    }

对应的xml文件xxx.xml

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="#ffececec">
        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
        </RelativeLayout>
    </LinearLayout>

此次情景  
版本与上面sdk设置不兼容，一下几个参数对版本都做了限制

minSdkVersion 19    //最小版本限制
        targetSdkVersion 28 //targetSdkVersion保证的是api的一致性。一般minSdkVersion <targetSdkVersion<= compileSdkVersion
