第三方控件Banner实现轮播

1.第一步，添加依赖：

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

compile 'com.github.bumptech.glide:glide:4.0.0-RC0'

2.添加权限：

3.关于Banner在布局中引用：

4.1加载固定的图片url

private List strList = new ArrayList<>();


private String[] images = {
        "http://l2.51fanli.net//tuan//images//1//5806eac956808.jpg",
        "http://l2.51fanli.net//tuan//images//b//580991bb30560.jpg",
        "http://l0.51fanli.net//tuan//images//b//58115f2593dc3.jpg",
        "http://l2.51fanli.net//tuan//images//0//57923840b054d.jpg",
        "http://l2.51fanli.net//tuan//images//e//58101e11ab164.jpg"};



for (String s:images) {
    strList.add(s);
}

4.2加载从网络获取的图片

用xutils3网络请求数据，需要导入xutils3的依赖和帮助类（自己导入）

private void getDataFromServer() {
     //url
    String url1 = "http://api.kkmh.com/v1/topic_new/discovery_list?gender=0&sa_event=eyJwcm9qZWN0Ijoia

udCI6IlJlYWRGaW5kUGFnZSJ9";


    RequestParams params1 = new RequestParams();
    params1.setUri(url1);

  //用xutils3网络请求数据，需要导入xutils3的依赖和帮助类（自己导入）
 x.http().get(params1, new Callback.CommonCallback() {

        @Override
        public void onSuccess(final String result) {

            if (result != null) {
                
                Gson gson = new Gson();
                BannerBean bannerBean = gson.fromJson(result, BannerBean.class);
                List infos = bannerBean.getData().getInfos();

           
                for (BannerBean.DataBean.InfosBean bb : infos) {

                    List banners = bb.getBanners();

                    for (BannerBean.DataBean.InfosBean.BannersBean nn : banners) {

                        String pic = nn.getPic();
                        strList.add(pic);
                    }
                }

                banner.setImageLoader(new BannerGilde());
                banner.setImages(strList);
                banner.setDelayTime(2000);
                banner.isAutoPlay(true);
                banner.start();

            }
        }
        
        @Override
        public void onError(Throwable ex, boolean isOnCallback) {
            Log.i(TAG, "onError: ");

        }

        @Override
        public void onCancelled(CancelledException cex) {

            Log.i(TAG, "onCancelled: ");
        }

        @Override
        public void onFinished() {

            Log.i(TAG, "onFinished: ");

        }
    });
    
}

5.需要继承imageLoader来操作图片的加载

class BannerGilde extends ImageLoader {

    @Override
    public void displayImage(Context context, Object path, ImageView imageView) {

        Glide.with(getContext()).load(path).into(imageView);

    }
}

以上就是所有代码
