# 步骤 #

1、新建一个项目，引入依赖包

implementation 'com.youth.banner:banner:2.1.0'
     implementation 'com.github.bumptech.glide:glide:4.12.0'

2、构造实体，放入列表

3、写入逻辑

package com.hnucm.c201901020110;
    
    import androidx.appcompat.app.AppCompatActivity;
    
    import android.os.Bundle;
    
    import com.bumptech.glide.Glide;
    import com.bumptech.glide.load.resource.bitmap.RoundedCorners;
    import com.bumptech.glide.request.RequestOptions;
    import com.youth.banner.Banner;
    import com.youth.banner.adapter.BannerImageAdapter;
    import com.youth.banner.holder.BannerImageHolder;
    import com.youth.banner.indicator.CircleIndicator;
    
    import java.util.ArrayList;
    import java.util.List;
    
    public class MainActivity extends AppCompatActivity { 
        Banner banner;
        List<String> stringList = new ArrayList<>();
        @Override
        protected void onCreate(Bundle savedInstanceState) { 
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            banner = findViewById(R.id.banner);
    
            stringList.add("https://ss0.baidu.com/94o3dSag_xI4khGko9WTAnF6hhy/zhidao/pic/item/a6efce1b9d16fdfabf36882ab08f8c5495ee7b9f.jpg");
            stringList.add("https://ss3.baidu.com/9fo3dSag_xI4khGko9WTAnF6hhy/zhidao/pic/item/0824ab18972bd40797d8db1179899e510fb3093a.jpg");
            stringList.add("https://ss2.bdstatic.com/70cFvnSh_Q1YnxGkpoWK1HF6hhy/it/u=2647888545,3751969263&fm=224&gp=0.jpg");
    
            banner.setAdapter(new BannerImageAdapter<String>(stringList) { 
                @Override
                public void onBindView(BannerImageHolder holder, String data, int position, int size) { 
                    Glide.with(holder.itemView)
                            .load(data)
                            .apply(RequestOptions.bitmapTransform(new RoundedCorners(30)))
                            .into(holder.imageView);
                }
            });
            banner.setIndicator(new CircleIndicator(this));
        }
    }
