I'm using a specific url to obtain an image online, but the url itself automatically changes every few minutes. I'm using ION library from Here The problem I'm having is when I refresh the page, the page itself looks like it is refreshing but the exact same picture is appearing. I'm assuming its a cached image? If I reinstall the application, then it obtains the correct image again.
This is how I'm using ION where imageID2[position] is just a typical url to a jpg.
Ion.with(imageView)
.placeholder(R.drawable.ic_launcher)
.error(R.drawable.ic_launcher)
.load(imageId2[position]);
Is there anyway I can disable the cache or just make it refind the images again?
使用.noCache()绕过缓存。
As per documentation here , use the "long" way to build an ImageView request so that you can add headers, noCache, etc.
Change your original request from this:
Ion.with(imageView)
.placeholder(R.drawable.ic_launcher)
.error(R.drawable.ic_launcher)
.load(urlString);
To this:
Ion.with(context)
.load(urlString)
.noCache()
.withBitmap()
.placeholder(R.drawable.ic_launcher)
.error(R.drawable.ic_launcher)
.intoImageView(imageView);
您可以在网址中附加一个唯一的字符串,例如当前时间戳,以强制Ion将每个请求视为唯一。
