Android录制视频，仿微信小视频录制（二）

Android录制视频，第二部分具体使用

简述

录制视频博客第一篇写了视频录制控件的相关内容（视频录制博客第一篇），这一篇里讲一下控件的具体使用。其实自己看一下控件的代码，很容易使用的，可以根据自己的要求定制一下参数什么的，这里的代码就各位就当个参考看看吧。

具体实现

录制页面大概这几个功能点：

显示录制进度

按下录制

上划取消录制

录制完成保存视频

退出页面删除视频文件或文件夹（可选）

注意的点

录制预览的尺寸需要设置的，控件的大小长宽比率需要配合预览尺寸，不然预览会变形的。还有就是我们公司项目是要自拍的，所以直接默认调用了前置摄像头，需要调用后置的可以在代码里更改。切换摄像头的需求没有，也就没做，有需求可以自己做一下。还有权限问题，录制前会有权限检测。注释还算比较详细的，具体可以参考注释。
