Android Ping相关方法整理

Android   Ping网址、IP以及网关地址方法汇总

    //判断传入的url地址是否为ip地址public boolean isIP(String string){if(string.toLowerCase().contains("http://") || string.toLowerCase().contains("https://")){string = string.split("/")[2];}else if(string.startsWith("/")){string = string.split("/")[1];}else{string = string.split("/")[0];}if(string.contains(":")){string = string.split(":")[0];}if(string.length() < 7 || string.length() > 15 || "".equals(string)){return false;}/*** 判断IP格式和范围*/String rexp = "([1-9]|[1-9]\\d|1\\d{2}|2[0-4]\\d|25[0-5])(\\.(\\d|[1-9]\\d|1\\d{2}|2[0-4]\\d|25[0-5])){3}";Pattern pat = Pattern.compile(rexp);  Matcher mat = pat.matcher(string);  boolean ipAddress = mat.find();return ipAddress;}

    //获取传入url地址的域名public boolean obtainDomain(String string){String domain = "";if(string.toLowerCase().contains("http://") || string.toLowerCase().contains("https://")){domain = string.split("/")[2];}else if(string.startsWith("/")){domain = string.split("/")[1];}else{domain = string.split("/")[0];}if(domain.contains(":")){domain = domain.split(":")[0];}return domain;}

//获取传入url的ip地址
