前言
第三方素材需要基于UtilsHelp
简介易学，很好的实战项目
需要资源的私聊我。
代码如下（示例）：
dependencies {
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation fileTree(dir: 'libs', include: ['*.aar', '*.jar'], exclude: [])
implementation 'com.google.android.material:material:1.1.0'
implementation 'androidx.vectordrawable:vectordrawable:1.1.0'
implementation 'androidx.navigation:navigation-fragment:2.1.0'
implementation 'androidx.navigation:navigation-ui:2.1.0'
implementation 'androidx.lifecycle:lifecycle-extensions:2.1.0'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
testImplementation 'junit:junit:4.12'
implementation 'androidx.cardview:cardview:1.0.0'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

2.设置轮播XML与编写
