如何在毕加索中清除缓存并重新加载图像? [英] How to clear cache and Reload Image in Picasso?

问题描述

我正在使用 Picasso 在我的应用程序中加载图像，但我面临的问题是我的图像 URL 相同但图像正在从 backend 更改> 调用相同的 URL 但 Picasso 加载保存在其缓存中的相同图像.现在我想清除该图像的缓存并再次重新加载图像.

I am using Picasso to load image in my application but i facing a issue that my image URL is same but image is changing from backend calling the same URL but Picasso loading the same image saved in its cache. Now i want to clear the cache for that Image and reload the image again.

我在 SO 上搜索过的尝试发现我们可以使用 picasso.invalidate(fileName); 或 memoryPolicy(MemoryPolicy.NO_CACHE) 但我在代码中收到错误消息

What i have tried i searched on SO find that we can use picasso.invalidate(fileName); or memoryPolicy(MemoryPolicy.NO_CACHE) but i am getting the error message in code

无法使 reslove 方法失效

Can't reslove method invalidate

无法重新调用方法 memoryPolicy

Can't reslove method memoryPolicy

gradle 中毕加索的依赖:

dependency for picasso in gradle :

compile 'com.squareup.picasso:picasso:2.4.0'

推荐答案

invalidate() 和 memoryPolicy() 是在库的更高版本中引入的.要使用其中任何一个，请将 picasso 更新到最新版本

invalidate() and memoryPolicy() were introduced in later versions of the library. To use either of them update picasso to the latest version

compile 'com.squareup.picasso:picasso:2.5.2'
