Glide加多本地图片文件缓存

需求：想在glide的基础上再做下载到本地 如果本地有图优先取用本地的图

示例代码如下：

private static ExecutorService cachedThreadPool;
    @SuppressLint("NewApi")
    public static void load(Context context, ImageView imageView, String url) {
        if (TextUtils.isEmpty(url)) {

            return;
        }
        if(!((Activity)context).isFinishing() && !((Activity)context).isDestroyed()){

            String beforeSaveFilePath = "";
            if (PermissionAppUtils.hasPermissions(context,PermissionAppUtils.Group.STORAGE)){
                String temp[] = url.replaceAll("\\\\","/").split("/");
                String fileUrlName = "";
                if(temp.length > 1){
                    fileUrlName = temp[temp.length - 1];
                }
                if (!fileUrlName.endsWith(".jpg")){
                    fileUrlName = fileUrlName+".jpg";
                }
                File file = new File(ToolUtils.getDownCustomerLocalPath());
                File[] subFile = file.listFiles();
                if (subFile != null && subFile.length > 0){
                    for (int iFileLength = 0; iFileLength < subFile.length; iFileLength++) {
                        // 判断是否为文件夹
                        if (!subFile[iFileLength].isDirectory()) {
                            String filename = subFile[iFileLength].getName();
                            if (filename.equals(fileUrlName)){
                                beforeSaveFilePath = subFile[iFileLength].getPath();
                                break;
                            }
                        }
                    }
                }

            }
            if (!TextUtils.isEmpty(beforeSaveFilePath)){
                loadLocalFile(context,imageView,beforeSaveFilePath);
            } else {
                Glide.with(context)
                        .asBitmap()
                        .load(url)

                        .dontAnimate()
                        
                        .error(Glide.with(context)
                                .load(url).into(imageView))
                        .into(new SimpleTarget<Bitmap>() {
                            @Override
                            public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {

                                if (PermissionAppUtils.hasPermissions(context,PermissionAppUtils.Group.STORAGE)){
                                    if (cachedThreadPool == null){
                                        cachedThreadPool = Executors.newCachedThreadPool();
                                    }
                                    cachedThreadPool.execute(new Runnable() {
                                        @Override
                                        public void run() {
                                            String temp[] = url.replaceAll("\\\\","/").split("/");
                                            String fileName = "";
                                            if(temp.length > 1){
                                                fileName = temp[temp.length - 1];
                                            }
                                            if (!fileName.endsWith(".jpg")){
                                                fileName = fileName+".jpg";
                                            }
                                            setBitmapToLocal(context,fileName,resource);
                                        }
                                    });

                                }
                                imageView.setImageBitmap(resource);
                            }
