SmartImageVIew，我想强制刷新（而不是缓存） [英] SmartImageVIew, I would like to force refresh (and not caching)

问题描述

我正在使用这个有用的类，允许智能在线下载图像（来自loopj家伙）。
它工作正常，但我无法在服务器中可能已更改的同名图像的情况下强制刷新（例如：我更新我的个人资料图片）。
所以目前我在setImageUrl（）之前强制删除我的app cache dir。
它有效，并引发了一些FileNotFoundException。没什么大不了的，但我讨厌没有真正工作的东西，我不知道你是否知道我的意思:)
很多谢谢，再次

I am using this useful class that allow smart online downloading of images (from the loopj guys). It works fine, but i cannot force the "refresh" in the case of same name images that could have been changed in the server (example: I update my profile picture). So at the moment I am forcing the brutal delete of my app cache dir before the setImageUrl(). It works, and some FileNotFoundException is raised. No big deal, but I hate having something that works "without really working", I don't know if you know what I mean :) Lots of thanks, again

Have a look at my answer to a similar question here

它主要涉及在您用于获取图像的URL的末尾附加一个参数，并确保每次调用该参数时该参数都是唯一的，从而强制进行新的调用。

It essentially involves appending a paramater to the end of the url you use to fetch the image and ensuring that the parameter is unique each time you call it thus forcing a fresh call.
