实例图：

1.引用XUI

http://t.csdnimg.cn/Wb4KR

2.创建显示图片布局 banner_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"android:layout_width="260dp"android:layout_height="100dp"app:cardCornerRadius="5dp"><ImageViewandroid:id="@+id/iv_item"android:layout_width="match_parent"android:layout_height="match_parent"android:scaleType="centerCrop" /></LinearLayout>

3.写个适配器继承 RecyclerView  BannerAdapter.java

package com.example.xuicarousel.xui.adapter;import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
import com.example.xuicarousel.R;
import com.xuexiang.xui.widget.imageview.ImageLoader;public class BannerAdapter extends RecyclerView.Adapter<BannerAdapter.BannerViewHolder> {private String[] urls;//图片地址private Context context;public BannerAdapter(Context context, String[] urls) {this.urls = urls;this.context = context;}@NonNull@Overridepublic BannerViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {View view = LayoutInflater.from(context).inflate(R.layout.banner_item, parent, false);return new BannerViewHolder(view);}@Overridepublic void onBindViewHolder(@NonNull BannerViewHolder holder, int position) {ImageView imageView = holder.imageView;//XUI 的图片加载器ImageLoader.get().loadImage(imageView, urls[position]);}@Overridepublic int getItemCount() {return urls.length;}class BannerViewHolder extends RecyclerView.ViewHolder {ImageView imageView;//轮播条的 item 项public BannerViewHolder(@NonNull View itemView) {super(itemView);imageView = itemView.findViewById(R.id.iv_item);}}
}

4.主布局xml  activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".MainActivity"><!-- 倒计时button--><!--轮播条控件--><ScrollViewandroid:id="@+id/scroll_view"android:layout_width="match_parent"android:layout_height="fill_parent"app:layout_constraintBottom_toBottomOf="parent"app:layout_constraintEnd_toEndOf="parent"app:layout_constraintHorizontal_bias="0.0"app:layout_constraintStart_toStartOf="parent"app:layout_constraintTop_toTopOf="parent"app:layout_constraintVertical_bias="0.0" ><LinearLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="vertical"><com.xuexiang.xui.widget.button.CountDownButtonandroid:id="@+id/bt_countdown4"style="@style/Button.Blue"android:text="轮播图："tools:ignore="MissingConstraints" /><!--
可以点进去自行查看  Ctrl +鼠标左键app:bl_centerScale 图片缩放系数，默认值是1.2。
app:bl_autoPlaying 是否自动滚动，默认为 true。
app:bl_orientation 轮播的方向，有垂直和水平两种方式。
app:bl_indicatorSelectedSrc 小黑点可以为其设置指定的资源文件
app:bl_indicatorSelectedColor 小黑点
索引器的对齐方式，默认left<attr format="enum" name="bl_indicatorGravity">轮播间隔，单位ms，默认是4000msapp:bl_interval="1000"app:bl_showIndicator="false" 不显示
轮播速度，默认是1.0F
app:bl_moveSpeed="1.8"--><com.xuexiang.xui.widget.banner.recycler.BannerLayoutandroid:id="@+id/bl"android:layout_width="match_parent"android:layout_height="200dp"android:layout_marginTop="8dp"app:bl_autoPlaying="true"app:bl_centerScale="1.9"app:bl_indicatorGravity="center"app:bl_indicatorSelectedColor="#ff00ff00"app:bl_itemSpace="10dp"app:bl_moveSpeed="1.1"></com.xuexiang.xui.widget.banner.recycler.BannerLayout><Viewandroid:id="@+id/view"android:layout_width="match_parent"android:layout_height="2dp"android:background="#ccc" /><com.xuexiang.xui.widget.banner.recycler.BannerLayoutandroid:id="@+id/bltwo"android:layout_width="match_parent"android:layout_height="200dp"android:layout_marginTop="8dp"app:bl_autoPlaying="true"app:bl_centerScale="1.5"app:bl_interval="1000"app:bl_itemSpace="10dp"app:bl_moveSpeed="1.1"app:bl_orientation="vertical"app:bl_showIndicator="false" /><Viewandroid:id="@+id/view2"android:layout_width="match_parent"android:layout_height="2dp"android:background="#ccc" /><com.xuexiang.xui.widget.banner.recycler.BannerLayoutandroid:id="@+id/blthree"android:layout_width="match_parent"android:layout_height="200dp"app:bl_autoPlaying="true"app:bl_centerScale="1.3"app:bl_itemSpace="10dp"app:bl_moveSpeed="1.1"></com.xuexiang.xui.widget.banner.recycler.BannerLayout></LinearLayout></ScrollView></androidx.constraintlayout.widget.ConstraintLayout>

5.MainActivity.java

package com.example.xuicarousel;import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import com.example.xuicarousel.xui.adapter.BannerAdapter;
import com.xuexiang.xui.widget.banner.recycler.BannerLayout;public class MainActivity extends AppCompatActivity {private BannerAdapter mAdapter;private BannerLayout mBl, mBlTwo, mBlThree;public String[] urls = new String[]{//轮播图片地址"http://photocdn.sohu.com/tvmobilemvms/20150907/144160323071011277.jpg","http://photocdn.sohu.com/tvmobilemvms/20150907/144158380433341332.jpg","http://photocdn.sohu.com/tvmobilemvms/20150907/144160286644953923.jpg","http://photocdn.sohu.com/tvmobilemvms/20150902/144115156939164801.jpg","http://photocdn.sohu.com/tvmobilemvms/20150907/144159406950245847.jpg",};@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mAdapter = new BannerAdapter(this, urls);mBl = findViewById(R.id.bl);mBl.setAdapter(mAdapter);mBlTwo = findViewById(R.id.bltwo);mBlTwo.setAdapter(mAdapter);mBlThree = findViewById(R.id.blthree);mBlThree.setAdapter(mAdapter);/*// 事件mBlThree.setOnIndicatorIndexChangedListener(new BannerLayout.OnIndicatorIndexChangedListener() {@Overridepublic void onIndexChanged(int position) {Toast.makeText(MainActivity.this,"轮播到了第 "+position+" 个"  ,Toast.LENGTH_SHORT).show();}});
*/}
}

6.其他配置

AndroidMainifest.xml 中联网权限：<uses-permission android:name="android.permission.INTERNET"/>//
上网配置
<application
...android:usesCleartextTraffic="true"
...
>buid.gradle 中：导入dependencies {//Xuiimplementation 'com.github.xuexiangjys:XUI:1.1.5'
...//解决加载图片报错implementation 'com.github.bumptech.glide:glide:4.11.0'implementation 'com.github.bumptech.glide:compiler:4.11.0'
...}
