或其他任何youtube格式，其中网址中包含视频ID

我正在尝试：-

  Pattern compiledPattern = Pattern.compile("(?<=v=).*?(?=&|$)",Pattern.CASE_INSENSITIVE);      
        Matcher matcher = compiledPattern.matcher(sourceUrl);
        if(matcher.find()){
            setVideoId(matcher.group());
        }

它不只对一个URL有效：

回答：

我找到了解决方案..我扩展了该URL ..及其工作..

public static String expandUrl(String shortenedUrl)  {
        URL url;
        String expandedURL = "";
        try {
            url = new URL(shortenedUrl);
            // open connection
            HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection(Proxy.NO_PROXY); 
            // stop following browser redirect
            httpURLConnection.setInstanceFollowRedirects(false);
            // extract location header containing the actual destination URL
            expandedURL = httpURLConnection.getHeaderField("Location");
            httpURLConnection.disconnect();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }    
         return expandedURL;
    }
