//域名后缀，需要可以添加   private static final String[] come = {            "top", "com.cn", "com", "net", "cn", "cc", "gov", "cn", "hk"    };   public static boolean isWebUrl(String url) {        StringBuilder sb = new StringBuilder();        sb.append("(");       for (String anExt : come) {           sb.append(anExt);           sb.append("|");       }        sb.deleteCharAt(sb.length() - 1);        sb.append(")");        String pattern = "((https?|s?ftp|irc[6s]?|git|afp|telnet|smb)://)?((\\d{1,3}\\.\\d{1,3}\\.\\d{1,3}\\.\\d{1,3})|((www\\.|[a-zA-Z\\.\\-]+\\.)?[a-zA-Z0-9\\-]+\\." + sb.toString() + "(:[0-9]{1,5})?))((/[a-zA-Z0-9\\./,;\\?'\\+&%\\$#=~_\\-]*)|([^\\u4e00-\\u9fa5\\s0-9a-zA-Z\\./,;\\?'\\+&%\\$#=~_\\-]*))";        return Pattern.compile(pattern).matcher(url).matches();    }

Kotlin 代码

val a= arrayOf(  "top", "com.cn", "com", "net", "cn", "cc", "gov", "cn", "hk");fun getCompleteUrl(text: String): Boolean {    var sb = StringBuilder();    sb.append("(");    for (f in a) {        sb.append(f);        sb.append("|");    }    sb.deleteCharAt(sb.length - 1);    sb.append(")");    val p = Pattern.compile("((https?|s?ftp|irc[6s]?|git|afp|telnet|smb)://)?((\\d{1,3}\\.\\d{1,3}\\.\\d{1,3}\\.\\d{1,3})|((www\\.|[a-zA-Z\\.\\-]+\\.)?[a-zA-Z0-9\\-]+\\." + sb.toString() + "(:[0-9]{1,5})?))((/[a-zA-Z0-9\\./,;\\?'\\+&%\\$#=~_\\-]*)|([^\\u4e00-\\u9fa5\\s0-9a-zA-Z\\./,;\\?'\\+&%\\$#=~_\\-]*))", Pattern.CASE_INSENSITIVE);    val matcher = p.matcher(text);    return matcher.matches()}

能满足百分之九十的需求。
