Android 轮播图

我们首先需要导入两个依赖

1：加载网络图片的依赖

2：轮播图

    implementation 'io.github.youth5201314:banner:2.2.2'
    implementation 'com.github.bumptech.glide:glide:4.13.0'
    annotationProcessor 'com.github.bumptech.glide:compiler:4.13.0'

添加布局文件：

添加图片：

package com.example.lunbo;
import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

import com.bumptech.glide.Glide;
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 bannerList=new ArrayList<>();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        banner=findViewById(R.id.banner);
        bannerList.add("https://p2.itc.cn/images01/20210510/096eeb9cd3c84bd8ba09b5713679b4f9.jpeg");
        bannerList.add("https://p2.itc.cn/images01/20210510/096eeb9cd3c84bd8ba09b5713679b4f9.jpeg");
        bannerList.add("http://i0.hdslb.com/bfs/article/97549c0fd58b940c1306faac923a8685551a6a2a.jpg");
      banner.setAdapter(new BannerImageAdapter(bannerList) {
          @Override
          public void onBindView(BannerImageHolder holder, String data, int position, int size) {
              Glide.with(holder.imageView)
                      .load(data)
                      .into(holder.imageView);
          }
      });
      //轮播图下面的原点
      banner.setIndicator(new CircleIndicator(this));
      banner.setIndicatorRadius(50);



    }
}
