使用VideoView和MediaController进行视频播放

一个视频播放的activity，可以直接拿过来用，比较简单，直接贴个代码留作记录，效果如下：



[java] view plain copy print?/**
* 视频播放的activity<br>
* 使用方法：<br>
* 1、AndroidManifest.xml中添加此activity<br>
* 2、Intent中存入待播放视频的URL，支持本地和网络<br>
* 3、启动这个activity<br>
* <br>
* example：<br>
* String url = “play url”;<br>
* Intent intent = new Intent();<br>
* intent.setClass(this, VideoPlayActivity.class);<br>
* intent.putExtra(VideoPlayActivity.KEY_URL, url);<br>
* startActivity(intent);<br>
