Glide用法记录（更新中。。）

1.从网络中读取图片保存到缓存中

 private String getImagePath(String imgUrl) {
        String path = null;
        FutureTarget<File> future = Glide.with(ViewBigImageActivity.this)
                .load(imgUrl)
                .downloadOnly(500, 500);
        try {
            File cacheFile = future.get();
            path = cacheFile.getAbsolutePath();
        } catch (InterruptedException | ExecutionException e) {
            e.printStackTrace();
        }
        return path; //返回缓存图片路径
    }
