Android 自定义Camera 使用TextureView GLSurfaceView预览
前言：抱着最起码的要求尽力去做好每一件事 ！ ——秋不白
记录学习音视频的过程，目前到 了音视频的录制，后面再学习openGl ES，FFmpeg等
前面有使用SurfaceView 来预览Camera以及拍照，根据重力传感器来动态设置Camera.setRotation(degree),横着拍摄的照片，应该是横着的，竖着拍摄的照片应该竖着的，对吧，符合常识。后来用TextureView GLSurfaceView 来预览Camera，我对CameraUtil进行了更改。TextureView GLSurfaceView来预览，工具类操作相同，主要是TextureView GLSurfaceView对应的回调处理方法不同，道理都是一样的，直接上代码吧
效果图：
先说明，预览和保存的分辨率都是写死的，保存照片的分辨率可以修改，有兴趣去码云上获取完整代码，查看对应的代码https://gitee.com/redrose/Demo。

另外在
PreViewGlsurfaceView中有bug，在拍照界面进入查看图片返回的时候，会闪到主界面或者崩溃，这个问题原因是没有释放Camera资源的问题，这个地方比较简单，我先把代码提交，下次我改了再提交到码云，仅供参考，完整代码可以去我的码云上去看，欢迎指正。
