How can i listen to the progress of image's loading

[jonyChina162]

I am now developing for a new app, and I need to update the progress bar manually when loading an image. However, glide's api seems unfriendly when I try to get the current progress.
In UIL lib, I can easily set an ImageLoadingListener to do this . I try to do the same thing but not modify the glide core lib, but I found it's hard for me.
So in glide lib , how can i listen to the progress of image's loading.
If there's no good answer, i think i had to use rxjava or modify the glide core lib(it's terrible).
Thank goodness for reading my aweful English

There isn't an easy way, see #232 (duplicate) for details.

#232 (comment) gave an idea how it may be possible, but the gist he provided seems to only work for one image only. You'll need OkHttp to try that out.
