为什么我的Glide不缓存图像?似乎重新下载了图像 [英] Why my Glide doesn't cache the image ? it seems download image all over again

问题描述

我正在尝试使用以下代码下载图像:

I am trying to download image using the code below:

Glide.with(recommendedEventViewHolder.itemView)
            .load(currentEvent.posterDownloadPath)
            .diskCacheStrategy( DiskCacheStrategy.AUTOMATIC )
            .into(recommendedEventViewHolder.posterImageView)

但在此视频中结果是这样的: https://drive.google.com/file/d/1ljGxwsi0wpaZbBY_CLmczdBzD9krz4QQ/view?usp=sharing

but the result is like this, in this video: https://drive.google.com/file/d/1ljGxwsi0wpaZbBY_CLmczdBzD9krz4QQ/view?usp=sharing

当我向下滚动到回收站"视图的底部，然后回到顶部时，第一个图像消失，似乎重新下载了该图像

when I scroll down to the bottom of recycler view, and then go back to the top, the first image disappear and it seems re download the image

我试图将diskStartegy删除为类似这样的内容:

I have tried to remove the diskStartegy to be something like this:

Glide.with(recommendedEventViewHolder.itemView)
                .load(currentEvent.posterDownloadPath)
                .into(recommendedEventViewHolder.posterImageView)

但是结果是一样的.我在gradle文件中使用了它

but the result is just the same. I am using this in my gradle file

implementation 'com.github.bumptech.glide:glide:4.9.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'

推荐答案

将diskCacheStrategy从DiskCacheStrategy.AUTOMATIC更改为DiskCacheStrategy.onlyRetrieveFromCache(true)，这仅在图像无法缓存时才尝试发送请求.

Change your diskCacheStrategy from DiskCacheStrategy.AUTOMATIC to DiskCacheStrategy.onlyRetrieveFromCache(true), this will only try to send request only if images failed to cache.
