一個視頻播放的activity，可以直接拿過來用，比較簡單，直接貼個[代碼](http://www.xuebuyuan.com/ "代碼")留作記錄，效果如下：
~~~
/**
* 視頻播放的activity<br>
* 使用方法：<br>
* 1、AndroidManifest.xml中添加此activity<br>
* 2、Intent中存入待播放視頻的URL，支持本地和網絡<br>
* 3、啟動這個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>
