android 获取相册列表的实现及源码下载（一）
来源：互联网 发布：淘宝达人公域权限开通 编辑：程序博客网 时间：2024/06/13 17:38
该项目实现的功能如下：
获取手机相册，点击每个相册之后进入该相册的图片列表界面，在图片列表界面可以实现图片多选，然后进入所选择的图片界面，在该界面内可以实现所选图片的上传等功能。
该项目最大特色：
1、获取相册列表，目前网络上面介绍获取相册的项目很少，本文专门讲述相册的获取。
2、使用Android-Universal-Image-Loader集成框架-第三方jar包加载本地图片，熟悉这个jar的开发者肯定不陌生，该jar包十分强大，除了可以获取网络图片，本地图片也是可以的。同时，通过引用第三方jar可以有效解决OOM异常问题。 
首先讲解获取手机相册的原理：
我们都知道获取手机图片要使用到ContentResolver这个类，但是通过这个类获取相册，是获取不到的，只能获取到相册的ID，相册封面图片无法获取（至少目前我在写本篇博文时，还不知道如何直接获取手机相册，如果大家知道如何直接获取相册的话勿怪哈，本人水平有限^_^，同时也请不吝赐教，请留言哈【握手】）。所以该项目在实现获取手机相册的时候，是通过先获取手机相册的ID，然后获取手机内容全部图片，通过比较图片所在的相册ID，把每一个图片归并到相应的相册中去。
现在给出获取相册以及相册内部图片的类，获取相册和图片在这一个类中完成。代码如下：
