Question

我想要一种类似Chrome的浏览器行为，当用户输入字符串时，浏览器会决定是将字符串视为网址还是Google查询字符串。

我怎样才能做到这一点？

我在努力，

boolean modifiedUrlValid = Patterns.WEB_URL.matcher(modifiedUrl).matches();

但这不适用于Android 5.0及以上。请帮忙。

此致

这是来自模式的原始来源的修改版本，这有用吗？使用方法与使用原始方法相同。

public class URLValidator {

    public static final String TOP_LEVEL_DOMAIN_STR_FOR_WEB_URL =

它最后由Google于2011年更新，意味着它与最近添加的许多域名不匹配。有关最新TLD列表，请参阅here。您可以继续将域添加到上面的源中，它最终会对匹配

的性能产生负面影响

编辑：不要使用 URLUtils，因为它只验证String是以http：//或https：//

开头的

boolean isValid = URLUtils.isValidUrl(urlString);
