加载图片的app
MyApp--去清单文件里面注册
public class MyApp extends Application {    @Override    public void onCreate() {        super.onCreate();        Fresco.initialize(this);    }}
加载图片的bean工具类
Image
public class Image {    public String urlGif;    public Image(String urlGif) {        this.urlGif = urlGif;    }    public Uri getUriGif(){        return Uri.parse(urlGif);    }}
MainActivity
