滑动后台线程在磁盘上的缓存图像 [英] Glide cache image on disk on background thread

问题描述

我想使用Glide急切下载图像并将其缓存在磁盘上以备将来使用.我想从后台线程调用此功能.

I want to use Glide to eagerly download images and cache them on disk for a future use. I want to call this functionality from a background thread.

我已阅读 Glide的缓存文档，但没有解释如何在没有实际目标的情况下下载图像.然后，我发现了此问题，并尝试使用类似的方法，但是无论如何我都能得到例外情况:

I've read Glide's caching documentation, but it doesn't explain how to download the image without having an actual target right now. Then I found this issue and tried to use a similar approach, but whatever I try I get this exception:

java.lang.IllegalArgumentException: You must call this method on the main thread

那么，如何告诉Glide从后台线程缓存图像?

So, how can I tell Glide to cache an image from a background thread?

编辑:我真的很想在后台线程上调用Glide的方法.我知道我可以使用Handler和其他方式将其卸载到UI线程，但这不是我要的.

I really want to call Glide's methods on background thread. I know that I can use Handler and other ways to offload it to UI thread, but that's not what I'm asking.

推荐答案

GlideApp.with(context)
    .downloadOnly()
    .diskCacheStrategy(DiskCacheStrategy.DATA) // Cache resource before it's decoded
    .load(url)
    .submit(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL)
    .get() // Called on background thread
