                    @Override
                    public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
                        PaletteUtil.getImageColor(resource,imageView);
                    }
                });

    }

}

注意事项：
1.设置一些配置的时候尽量使用

final RequestOptions options = new RequestOptions();
        options.skipMemoryCache(false);
        options.diskCacheStrategy(DiskCacheStrategy.ALL);
        options.priority(Priority.HIGH);
        options.error(R.mipmap.home_img_loading_pic1);
        options.placeholder(R.mipmap.home_img_loading_pic1);

但是在调用的使用一定要认清调用apply(options)方法。如果在使用的时候图片没有显示连设置的各种占位图都没有，很大可能就是调用的方法出错，因为之前版本的方法不一样。(我自己经历的血的教训)
