前言：

微信朋友圈网上有很多开源的例子，本文是自己手写，之前的几篇都是单个功能，感觉很零散，这次放出完整的点赞评论和朋友圈列表功能，大家有兴趣可以看一下

1.定义四种item类型，可以按后台接口自行定义类型:

2.CircleAdapter实现代码:

部分核心代码截图:

@Overrideprotected void onDestroy() {super.onDestroy();//释放播放器if (videoView != null) {videoView.release();videoView = null;}}
}

9.总结：

图片保存刚开始没用线程，导致要保存2次才能成功，后面改为handler发消息,后面会加上视频播放和点击item跳转网页详情，这一篇也是在前几篇的基础上，解决了很多问题，比如适配9.0http访问网络、约束布局的使用、评论时定位到当前位置、使用第三方状态栏库导致输入框焦点不弹出、评论成功后不是请求后台数据而是刷新本地数据等等.本例子是写的假数据，实时请求还需修改请求逻辑，基本的逻辑都写好了，如有问题及时反馈，我会积极改进.
