我在我的活动及其工作中使用以下工具。但我得到的输出(主机名)不是我想要的方式。例如,如果我需要找到谷歌的IP,我得到它像www.google.com/74.125.224.72
应该就像74.125.224.72
我是Android新手,请帮帮我。这是我的代码:
String host = editText1.getText().toString();
try {
InetAddress[] hostInetAddress = InetAddress.getAllByName(host);
String all = "";
for(int i = 0; i < hostInetAddress.length; i++){
all = all + hostInetAddress[i].toString() + "\n";
}
textInetAddress.setText(all);
}

使用以下命令获取您的姓名/ ip_address:
InetAddress address = InetAddress.getByName(new URL(urlString).getHost());
//it will fetch name/ip_address (eg. www.google.com/74.125.224.72) of the url you enter
然后使用:
获取ip_addressString ip = address.getHostAddress();
//it will fetch only ip_address (eg. "74.125.224.72" ) from the abouve url
所以而不是
for(int i = 0; i < hostInetAddress.length; i++){
all = all + hostInetAddress[i].toString() + "\n";
}
使用以下代码
for(int i = 0; i < hostInetAddress.length; i++){
all = all + hostInetAddress[i].getHostAddress().toString() + "\n";
}

试试这个:
String[] ip = all.split("/");
textInetAddress.setText(ip[1]);

无需循环。这样可行。
hostInetAddress [0] .getHostAddress();
