第一步:需要倒banner依赖

compile 'com.youth.banner:banner:1.4.9'compile 'com.github.bumptech.glide:glide:3.7.0'

第二步写代码

package myapplication7.myapplication9;import android.content.Context;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.widget.ImageView;import com.bumptech.glide.Glide;import com.google.gson.Gson;import com.youth.banner.Banner;import com.youth.banner.loader.ImageLoader;import java.io.IOException;import java.util.ArrayList;import java.util.Arrays;import java.util.List;import okhttp3.Call;import okhttp3.Callback;import okhttp3.OkHttpClient;import okhttp3.Request;import okhttp3.Response;public class MainActivity extends AppCompatActivity {    private List<MyBean.DataBean.Ad1Bean> ad1;    private Banner banner;    private List<String> list;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        banner = (Banner) findViewById(R.id.banner);        getData();        banner.setImageLoader(new ImageLoaderBanner());        list = new ArrayList<>();    }    public void getData(){        OkHttpClient client=new OkHttpClient();        Request request=new Request.Builder()                .url("http://m.yunifang.com/yunifang/mobile/home")                .build();        client.newCall(request).enqueue(new Callback() {            @Override            public void onFailure(Call call, IOException e) {            }            @Override            public void onResponse(Call call, Response response) throws IOException {                final String str=response.body().string();                runOnUiThread(new Runnable() {                    @Override                    public void run() {                        Gson gson=new Gson();                        MyBean bean=gson.fromJson(str,MyBean.class);                        ad1 = bean.getData().getAd1();                        list.add(ad1.get(0).getImage());                        list.add(ad1.get(1).getImage());                        list.add(ad1.get(2).getImage());                        //设置集合                        banner.setImages(list);                        //banner执行完方法之后调用                        banner.start();                    }                });            }        });    }    public class ImageLoaderBanner extends ImageLoader {        @Override        public void displayImage(Context context, Object path, ImageView imageView) {//Glide设置图片的简单用法            Glide.with(context).load(path).into(imageView);        }    }}
