1,.在使用Banner的时候需要添加依赖

compile 'com.youth.banner:banner:1.4.9'

2.还要初始化ImageLoader的配置

3.创建MImageLoader

public class MImageLoader extends ImageLoader {    @Override    public void displayImage(Context context, Object path, ImageView imageView) {        com.nostra13.universalimageloader.core.ImageLoader.getInstance().displayImage(path.toString(),imageView);    }}

4.代码展示

public class MainActivity extends AppCompatActivity {    private List<String> list;    private Banner banner;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        list = new ArrayList<>();        new MHttpURLConnectionAsyncTask().execute("http://www.93.gov.cn/93app/data.do?channelId=0&startNum=0");    }        //网络获取数据        class MHttpURLConnectionAsyncTask extends AsyncTask<String,Void,String> {            @Override            protected String doInBackground(String... strings) {                try {                    URL url = new URL(strings[0]);                    HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();                    int responseCode = urlConnection.getResponseCode();                    if (responseCode == 200) {                        InputStream inputStream = urlConnection.getInputStream();                        BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));                        StringBuffer buffer = new StringBuffer();                        String string = "";                        while ((string = reader.readLine()) != null) {                            buffer.append(string);                        }                        return buffer.toString();                    }                } catch (MalformedURLException e) {                    e.printStackTrace();                } catch (IOException e) {                    e.printStackTrace();                }                return null;            }            @Override            protected void onPostExecute(String s) {                super.onPostExecute(s);                Gson gson = new Gson();                JsonBean jsonBean = gson.fromJson(s, JsonBean.class);                List<JsonBean.DataScrollBean> dataScroll = jsonBean.getDataScroll();                for(int i=0;i<dataScroll.size();i++){                    list.add("http://www.93.gov.cn/"+dataScroll.get(i).getIMAGEURL());                    Log.e("AAAAAAAa",list.get(i));                }                banner = (Banner) findViewById(R.id.banner);                //设置banner样式                // banner.setBannerStyle(BannerConfig.CIRCLE_INDICATOR_TITLE_INSIDE);                //设置图片加载器                banner.setImageLoader(new MImageLoader());                //设置图片集合                banner.setImages(list);                //设置banner动画效果                //banner.setBannerAnimation(Transformer.RotateDown);                //设置标题集合（当banner样式有显示title时）                //banner.setBannerTitles(imageTitle);                //设置轮播时间                banner.setDelayTime(3000);                //设置指示器位置（当banner模式中有指示器时）                //banner.setIndicatorGravity(BannerConfig.CENTER);                //banner设置方法全部调用完毕时最后调用                banner.start();            }        }}
