Android surfaceView+播放视频

布局:

下面有两个主类,第一个MainActivity是加播放进度条的,shipin这个是最简单的,就单独的一个播放视频

MainActivity:

            mediaPlayer.setDisplay(surfaceView.getHolder());//绑定surfaceview

            mediaPlayer.prepare();//必须有 预准备
            mediaPlayer.start();//启动播放

        } catch (IOException e) {

    }
}

一定不要忘了加网络权限:
