Fresco加载本地图片卡顿

Question

在gridview中使用Fresco加载本地图片，结果非常卡，一开始是直接

 setImageURI

后来这样写也是很卡

  Uri uri = Uri.fromFile(new File(list.get(position).path));
            int width = 60, height = 60;
            ImageRequest request = ImageRequestBuilder.newBuilderWithSource(uri)
                    .setResizeOptions(new ResizeOptions(width, height))
                    .build();

            DraweeController controller = Fresco.newDraweeControllerBuilder()
                            .setOldController(holder.showImg.getController())
                            .setImageRequest(request)
                            .build();

四张图片就开始卡，图片加载慢，点击事件两秒之后才触发

setDownsampleEnabled(true)加这个就好了
