最近做开发需要解决一个模仿微信朋友圈附加图片的功能，具体要求如下：
（1）从手机中最多选择3张图片，可拍照上传；
（2）选择的图片可以点击移除然后再添加新图片；
（3）可以在手机包含图片的各个文件夹中随意选择等。
本博客主要实现的是以上功能，其他诸如主界面布局、各种控件添加和提交功能等旨在说明问题，只做了简单处理，重点在图片选择添加部分。该功能的实现主要引用了一个图片加载的开源框架universal-image-loader。
其中截图如下：
为了不过于冗余，过滤了部分布局文件和资源文件，在这里提供源码下载地址，有兴趣的读者可以下载观看（注：我使用的 AndroID Studio 1.4,SdkVersion 为23 ，在小米note【AndroID 4.4 】上调试）。
