用手机内置视频播放器播放视频

Question

我有一个简单的按钮，我希望通过点击此按钮播放URL视频（xxx.mp4），但没有videoView或webView。所以如果我点击按钮，手机会询问我选择播放视频的内部播放器。

按钮来播放视频：BUTTON3

这里是xml和java文件，我应该在这些文件中添加哪些代码？并且请发表评论时的所有代码（不仅是更正部分），谢谢

使用以下代码播放视频。

Intent intent = new Intent(Intent.ACTION_VIEW); 
     intent.setDataAndType(Uri.parse(sampleFile), "video/mp4"); 
     startActivity(intent); 

sampleFile是您的视频网址。
