本文介绍了一种在安卓应用中实现轮播图的方法，通过使用Banner库并结合Gson进行JSON数据解析，实现了从远程服务器获取数据并展示轮播图的功能。该方案包括了图片加载、自动轮播及轮播时间间隔等关键特性。

public class MainActivity extends AppCompatActivity {
    private Data mData;
    private Banner mBanner;
    private ListView mListView;
    private List<Data.DataBean> list;
    private List<String> listimag;
    private List<String> listtitle;
    private String urlPath="http://zkread.com/htnewsroom/articles/tops";
    Handler mHandler = new Handler(){
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            list = new ArrayList<>();
            listimag = new ArrayList<>();
            listtitle = new ArrayList<>();
            mData = new Gson().fromJson(msg.obj.toString(),Data.class);
            list.addAll(mData.getData());
            for (Data.DataBean bean:list){
                listimag.add(bean.getImgSrc());
                listtitle.add(bean.getTitle());
           }
            mBanner .setImageLoader(new MyLoader());
            //设置图片集合
            mBanner.setBannerStyle(BannerConfig.CIRCLE_INDICATOR_TITLE);
            mBanner.setImages(listimag);
            mBanner.setBannerTitles(listtitle);
            //设置自动轮播，默认为true
            mBanner.isAutoPlay(true);
            //设置轮播时间
            mBanner.setDelayTime(1500);
            //设置指示器位置（当banner模式中有指示器时）
            mBanner.setIndicatorGravity(BannerConfig.CENTER);
            //banner设置方法全部调用完毕时最后调用
            mBanner.start();
        }
    };



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mBanner = (Banner) findViewById(R.id.banner);

        yaya();
    }

    private void yaya() {
        new Thread() {
            @Override
            public void run() {
                super.run();

                String result = Utils.parmrs(urlPath);
                Message msg = new Message();
                msg.obj = result;
                mHandler.sendMessage(msg);
            }
        }.start();
    }}




public class MyLoader extends ImageLoader {
    public void displayImage(Context context, Object path, ImageView imageView) {

        Glide.with(context).load((String) path).into(imageView);       //传入路径,因为list为String格式,path为Object格式,所以强制类型转换.

    }
}
