//圓形
public static void load(Context context, String url, ImageView iv){
    RequestManager glideRequest = Glide.with(context);
    glideRequest.load(url).diskCacheStrategy(DiskCacheStrategy.ALL).transform(new GlideCircleTransform(context)).into(iv);
}
//長方形
public static void loadF(Context context, String url, ImageView iv){
    RequestManager glideRequest = Glide.with(context);
    glideRequest.load(url).diskCacheStrategy(DiskCacheStrategy.ALL).into(iv);
}
