现在恰好有个项目需要做个轮播图效果，这个需求也是很常见的需求，于是就做个笔记写一下实现过程

分为加载本地图片和网络图片

加载本地图片

第一步：先在build.gradle中加入banner和glide的依赖

	//banner依赖
	implementation 'com.youth.banner:banner:1.4.9'
    //Glide框架
    implementation "com.github.bumptech.glide:glide:4.6.1"

第二步：xml布局

<com.youth.banner.Banner
        android:id="@+id/banner"
        android:layout_width="match_parent"
        android:layout_height="300dp"
       />

第三步：MainActivity

public class MainActivity extends AppCompatActivity {
    private Banner mBanner;
    private LocalImageLoader mImageLoader;
    private ArrayList<Integer> imagePath;
    private ArrayList<String> imageTitle;
   @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        intView();
        intDate();
    }
    private void intDate() {
        imagePath = new ArrayList<>();
        imageTitle = new ArrayList<>();
        imagePath.add(R.mipmap.ic_launcher);
        imagePath.add(R.mipmap.ic_launcher);
        imagePath.add(R.mipmap.ic_launcher);
        imagePath.add(R.mipmap.ic_launcher);
        imagePath.add(R.mipmap.ic_launcher);
        imageTitle.add("第一");
        imageTitle.add("第二");
        imageTitle.add("第三");
        imageTitle.add("第四");
        imageTitle.add("第五");
    }
    private void intView() {
        mImageLoader = new LocalImageLoader();
        mBanner = findViewById(R.id.banner);
        //样式
        mBanner.setBannerStyle(BannerConfig.CIRCLE_INDICATOR_TITLE);
        //加载器
        mBanner.setImageLoader(mImageLoader);
        //动画效果
        mBanner.setBannerAnimation(Transformer.ZoomOutSlide);
        //图片标题
        mBanner.setBannerTitles(imageTitle);
        //间隔时间
        mBanner.setDelayTime(4500);
        //是否为自动轮播
        mBanner.isAutoPlay(true);
        //图片小点显示所在位置
        mBanner.setIndicatorGravity(BannerConfig.CENTER);
        //图片加载地址
        mBanner.setImages(imagePath);
        //启动轮播图。
        mBanner.start();
        //监听轮播图
        mBanner.setOnBannerListener(new OnBannerListener() {
            @Override
            public void OnBannerClick(int position) {
                Toast.makeText(MainActivity.this, "点击了" + (position + 1) + "张轮播图", Toast.LENGTH_SHORT).show();
            }
        });
    }
    /**
     * 图片加载类
     */
    private class LocalImageLoader extends ImageLoader {
        @Override
        public void displayImage(Context context, Object path, ImageView imageView) {
            Glide.with(context.getApplicationContext())
                    .load(path)
                    .into(imageView);
        }
    }
}

加载网络图片

只要修改一下intDate(）和LocalImageLoader（）方法就好了

例如：

	private void initData() {
        list_path.add("https://image.baidu.com/search/detail?ct=503316480&z=0&ipn=d&word=%E5%93%86%E5%95%A6A%E6%A2%A6&step_word=&hs=0&pn=8&spn=0&di=118140&pi=0&rn=1&tn=baiduimagedetail&is=0%2C0&istype=0&ie=utf-8&oe=utf-8&in=&cl=2&lm=-1&st=undefined&cs=3835923757%2C1980937759&os=265876109%2C1976020808&simid=0%2C0&adpicid=0&lpn=0&ln=1495&fr=&fmq=1573545585312_R&fm=&ic=undefined&s=undefined&hd=undefined&latest=undefined&copyright=undefined&se=&sme=&tab=0&width=undefined&height=undefined&face=undefined&ist=&jit=&cg=&bdtype=0&oriquery=&objurl=http%3A%2F%2Fimg24.pplive.cn%2Fcs180x240%2F2017%2F11%2F08%2F18331958489.jpg&fromurl=ippr_z2C%24qAzdH3FAzdH3Fe_z%26e3Brrpe_z%26e3Bv54AzdH3Frw2jAzdH3Ftwtk9F2rHzdii0tkWE_z%26e3Bip4s&gsm=&rpstart=0&rpnum=0&islist=&querylist=&force=undefined"); 
        list_path.add("https://image.baidu.com/search/detail?ct=503316480&z=0&ipn=d&word=%E5%93%86%E5%95%A6A%E6%A2%A6&step_word=&hs=0&pn=8&spn=0&di=118140&pi=0&rn=1&tn=baiduimagedetail&is=0%2C0&istype=0&ie=utf-8&oe=utf-8&in=&cl=2&lm=-1&st=undefined&cs=3835923757%2C1980937759&os=265876109%2C1976020808&simid=0%2C0&adpicid=0&lpn=0&ln=1495&fr=&fmq=1573545585312_R&fm=&ic=undefined&s=undefined&hd=undefined&latest=undefined&copyright=undefined&se=&sme=&tab=0&width=undefined&height=undefined&face=undefined&ist=&jit=&cg=&bdtype=0&oriquery=&objurl=http%3A%2F%2Fimg24.pplive.cn%2Fcs180x240%2F2017%2F11%2F08%2F18331958489.jpg&fromurl=ippr_z2C%24qAzdH3FAzdH3Fe_z%26e3Brrpe_z%26e3Bv54AzdH3Frw2jAzdH3Ftwtk9F2rHzdii0tkWE_z%26e3Bip4s&gsm=&rpstart=0&rpnum=0&islist=&querylist=&force=undefined");

    }
  private class LocalImageLoader extends ImageLoader {
        @Override
        public void displayImage(Context context, Object path, ImageView imageView) {
            Glide.with(context.getApplicationContext())
                    .load((String) path)
                    .into(imageView);
        }
    }

下载网络图片的时候要记得添加网络权限

<uses-permission android:name="android.permission.INTERNET" />

补充。轮播图几种默认样式对比。。。PS：如果轮播图不想要title，就更改样式就好了

需要注意的是，如果设置有标题出现的样式，那么一定要设置setBannerTitles属性，不然会报错

样式一：CIRCLE_INDICATOR：无标题，有小圆点

//banner无标题样式
mBanner.setBannerStyle(BannerConfig.CIRCLE_INDICATOR);

效果图：

在这里插入图片描述

样式二：CIRCLE_INDICATOR_TITLE_INSIDE：小圆点和标题在同一栏

mBanner.setBannerStyle(BannerConfig.CIRCLE_INDICATOR_TITLE_INSIDE);

效果图

在这里插入图片描述

样式三：CIRCLE_INDICATOR_TITLE：标题和小圆点同时出现

mBanner.setBannerStyle(BannerConfig.CIRCLE_INDICATOR_TITLE);

效果图：

在这里插入图片描述
