Android的对象缓存 [英] Android Objects Cache

问题描述

寻找一个简单的开源非copyleft的缓存为Android（SDK 7+）类。

Looking for a simple open source non-copyleft caching for Android (SDK 7+) class.

的目的是主要的存储位图取值取出异步（所以我不需要这个功能包含在缓存类）。

The purpose is primary to store the Bitmaps fetched asynchronously (so i don't need this functionality to be included in the cache class).

我使用的是weakList为了这个目的，那自然是一个不错的解决方案，与番石榴缓存是一个更好一点，但仍然不精。

I was using a weakList for this purpose, that was naturally a bad solution, with Guava cache that is a little better but still not fine.

这是preferred高速缓存可以存储任何可序列化对象，不只是一个位图，而且我可以很容易地清除使用的某些标记的对象，而对象添加到缓存中。

It's preferred that the cache is able to store any serializable Object, not just a Bitmap, and that i could easily purge the objects of certain tag used while the object is added to cache.

最好的办法是让文件系统缓存像包裹SQLite数据库。 这将是巨大的，如果缓存将由设置＆gt被清除;管理用途＆gt;清除缓存

The best option would be to get the filesystem cache like wrapping the sqlite database. It would be great if the cache would be cleared by Settings >Manage Application > Clear Cache

推荐答案

以上纯LruCache建议是在内存中缓存。从你的问题听起来好像你正在寻找一个磁盘缓存解决方案。

The plain LruCache suggested above is an in memory cache. From your question it sounds like you are looking for a disk cache solution.

阅读磁盘缓存高速缓存位图的android培训文档的

Read the Disk Cache of the Caching Bitmaps android training doc.

然后看看在DiskLruCache执行以下主题进行讨论： <一href="http://stackoverflow.com/questions/10185898/using-disklrucache-in-android-4-0-does-not-provide-for-opencache-method">Using DiskLruCache在安卓4.0不提供openCache方法

Then take a look at the DiskLruCache implementation discussed on the following thread : Using DiskLruCache in android 4.0 does not provide for openCache method

您可以抢在GitHub上 DiskLruCache 源。

You can grab the DiskLruCache source on GitHub.
