【移动应用开发技术】Android怎么实现仿微信朋友圈图片选择器

这篇文章主要为大家展示了“Android怎么实现仿微信朋友圈图片选择器”，内容简而易懂，条理清晰，希望能够帮助大家解决疑惑，下面让在下带领大家一起研究并学习一下“Android怎么实现仿微信朋友圈图片选择器”这篇文章吧。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AndroidStudio1.4,SdkVersion为23，在小米note【Android4.4】上调试）。下面开始我们的主要内容：主界面布局activity_main.xml(主要使用一个GridView实现)：<?xml
