android surfaceView+mediaPlayer 自定义视频播放器

Android 视频播放一般分为两种（其实3种，还一种是调Android自带播放器）：
1.使用Android自带View VideoView ,其中一些功能，已经都给实现好了(此view一般不满足自己的需求，比如：界面啊，控制啊，以及可能还有手势控制音量，手势控制亮度等等，那么就会选择第二种方式)
2.surfaceView+mediaPlayer 自定义播放器（这个可以制作自己想要任何功能以及界面的播放器，当然前提得自己实现）
主要就是
surfaceView：界面输出
mediaPlayer ：媒体控制：包括音量，暂停，播放，停止等等，还有视频各种状态的监听等等。
本片博文不对surfaceView和mediaPlayer 这两个类细解，如果你不了解这两个类的话，看本博文之前应该先去好好了解一下，不然很难看懂，在这里就不说了，直接看效果。
