After the image is updated, Glide loading is still the original image problem

reason

Glide cannot update the image due to cache when loading the same URL

Workaround

1, remove cache

If it is a local image, you can cancel the cache, which is a relatively simple operation:

 .skipMemoryCache(true) // don't use memory cache.diskCacheStrategy(DiskCacheStrategy.NONE) // don't use disk cache.into(imageView); 

2, using signature

Regardless of the local image network image, another method can be used, that is to use Glide's method .signature(Key signature), by creating a signature, and then changing the signature when the image is updated to achieve the effect of reloading.The signature can be a String or the time when the image is updated

 Glide.with(getActivity()).load(urlString).signature(new ObjectKey(DateTimeUtil.GetNowTime()))//You can also use system milliseconds System.currentTimeMillis().into(portrait);

Note: The new StringSignature() class in Glide 4.0 is no longer supported and needs to be changed to new ObjectKey()

Tools used

public class DateTimeUtil {public static String GetNowTime() {SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");Date curDate = new Date(System.currentTimeMillis());// Get the current timeString str = formatter.format(curDate);return str;}}
