Glide 清除特定图片缓存

本地使用的是Glide 4.16.0 版本，实现方式如下：

找到Url所对应的本地缓存

  public static String getCacheFile(Context mContext, String url) {
        DataCacheKey dataCacheKey = new DataCacheKey(new GlideUrl(url), EmptySignature.obtain());
        SafeKeyGenerator safeKeyGenerator = new SafeKeyGenerator();
        String safeKey = safeKeyGenerator.getSafeKey(dataCacheKey);
        File file = new File(mContext.getCacheDir() + "/glide");
        return file.getAbsolutePath()+"/"+safeKey+".0";
    }

直接删除文件即可

 public static boolean deleteDir(File dir) {
        if (dir != null && dir.isDirectory()) {
            String[] children = dir.list();
            for (int i = 0; i < Objects.requireNonNull(children).length; i++) {
                boolean success = deleteDir(new File(dir, children[i]));
                if (!success) {
                    return false;
                }
            }
        }
        assert dir != null;
        return dir.delete();
    }
