android-->>>mediarecorder的使用

最近研究一下怎么使用android录像功能，在网上找的例子无尽的报错，脑袋都大了，还好现在一个一个解决了...........。
遇到了N多个问题，开始时start failed，后来又stop failed，整理在这供自己以后学习参考，如果大家有更好的方法-->>回帖告诉俄这个菜鸟哦....
先给个图吧，测试时在模拟器上测试的.......,在真机上测试有效(2.3.3系统)
（添加--->>>添加摄像预览及双击屏幕拉近镜头功能.......,还有待其他功能的实现）真机测试不同的型号可能问题，有待解决........
（修改--->>修改第一次播放完回来在缩放的时候报错.....（解决））
(添加长按拉远焦距)修改使用seekbar缩放镜头，对于start failed错误一般是摄像大小有问题(本类在华为c8812上测试无压力，使用的是480p拍摄，720p报错)，还有就是上次使用了摄像头但是没有释放资源导致错误(一定要记得释放，要不然在真机上系统摄像头都会报错的......)。记得别忘了加权限..........
效果图如下：
中间是个抽屉可以选择不同的拍摄场景，右边拖动条负责缩放焦距
主要代码如下：
main.xnl布局如下：
drawer_item.xml布局如下：
