Android直播代码中动态功能的实现

动态功能，类似微信朋友圈，用户可以发布文字图片视频音频等内容，分享自己的日常生活。目前直播app是市场的宠儿，在直播app中加入动态功能可以增加趣味性和用户粘性，是互动直播之外的重要内容。下面以云豹直播系统的直播代码为例，为大家展现具体的直播代码实现方式

注意：

1. 本文仅用于Android端直播代码
2. 本文仅供参考

如上图所示，动态页面由一个列表呈现 ，根据动态的内容，分为图片、视频和音频等不同类型，不同类型的内容使用不同的布局，图片类动态根据图片的数量使用不同的布局。图片、视频和音频可以进行点击播放，观众可以对本条动态进行评论、点赞或举报等。

这个直播代码的列表使用RecyclerView，根据不同的类型，使用不同的item布局和ViewHolder进行展示。
具体直播代码如下：
