Android原生视频播放器
1、基本使用
private VideoView videoView;
/**
* 本地视频播放
*/
videoView.setVideoPath("");
/**
* 网络视频播放
*/
videoView.setVideoURI(Uri.parse(""));
/**
* 使用MediaController控制视频播放
*/
MediaController controller=new MediaController(this);
/**
* 设置VideoView与MediaConroller类建立关联
*/
videoView.setMediaController(controller);
/**
* 设置MediaConroller与VideoView建立关联
*/
controller.setMediaPlayer(videoView);2、设置自定义界面，横竖屏切换，调节音量和亮度
