Banner(联网获取图片的轮播)

1.导依赖

implementation \'com.youth.banner:banner:1.4.9\'

2.写布局

<?  version=\"1.0\" encoding=\"utf-8\"?>
<LinearLayout  ns:android=\"http://schemas.android.com/apk/res/android\"
android:layout_width=\"match_parent\"
android:layout_height=\"match_parent\">

<com.youth.banner.Banner
    android:id=\"@+id/banner\"
    android:layout_width=\"match_parent\"
    android:layout_height=\"200dp\">
</com.youth.banner.Banner>

</LinearLayout>

3.写代码

public class Fra1 extends Fragment {

private Banner banner;
//获取图片
String[] urls = {\"http://img.my.csdn.net/uploads/201407/26/1406383265_8550.jpg\",
        \"http://img2.91.com/uploads/allimg/140331/32-1403311A009.jpg\",
        \"http://img1.imgtn.bdimg.com/it/u=3055632223,2826867768&fm=214&gp=0.jpg\",
        \"http://img.article.pchome.net/00/28/41/62/pic_lib/wm/hlfjkpbz_17.jpg\",
        \"http://img0.imgtn.bdimg.com/it/u=2631448432,2817427988&fm=214&gp=0.jpg\",
        \"http://img.ichemo.cn/model/5188ebc96c74dd.jpg\"};

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fra1, null);
    banner = view.findViewById(R.id.banner);
    final ImageLoader instance = ImageLoader.getInstance();
    banner.setImageLoader(new com.youth.banner.loader.ImageLoader() {
        @Override
        public void displayImage(Context context,   path, ImageView imageView) {
            instance.displayImage((String) path,imageView);
        }
    });
    banner.setImages(Arrays.asList(urls));
    banner.start();
    return view;
}
}
