android获取wifi外网ip的方法
// 获取外网IP
public static String GetNetIp() {
URL infoUrl = null;
InputStream inStream = null;
try {
// http://iframe.ip138.com/ic.asp
// infoUrl = new URL("http://city.ip138.com/city0.asp");
infoUrl = new URL("http://ip38.com");
URLConnection connection = infoUrl.openConnection();
HttpURLConnection httpConnection = (HttpURLConnection) connection;
int responseCode = httpConnection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
inStream = httpConnection.getInputStream();
BufferedReader reader = new BufferedReader(
new InputStreamReader(inStream, "utf-8"));
StringBuilder strber = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null)
strber.append(line + "\n");
inStream.close();
// 从反馈的结果中提取出IP地址
// int start = strber.indexOf("[");
// Log.d("zph", "" + start);
// int end = strber.indexOf("]", start + 1);
// Log.d("zph", "" + end);
line = strber.substring(378, 395);
line.replaceAll(" ", "");
return line;
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
另有一个获取外网IP的高端方法
public static String GetNetIp()
{
String IP = "";
try
{
String address = "http://ip.taobao.com/service/getIpInfo2.php?ip=myip";
URL url = new URL(address);
HttpURLConnection connection = (HttpURLConnection) url
.openConnection();
connection.setUseCaches(false);
if (connection.getResponseCode() == HttpURLConnection.HTTP_OK)
{
InputStream in = connection.getInputStream();
// 将流转化为字符串
BufferedReader reader = new BufferedReader(
new InputStreamReader(in));
String tmpString = "";
StringBuilder retJSON = new StringBuilder();
while ((tmpString = reader.readLine()) != null)
{
retJSON.append(tmpString + "\n");
}
JSONObject jsonObject = new JSONObject(retJSON.toString());
String code = jsonObject.getString("code");
if (code.equals("0"))
{
JSONObject data = jsonObject.getJSONObject("data");
IP = data.getString("ip") + "(" + data.getString("country")
+ data.getString("area") + "区"
+ data.getString("region") + data.getString("city")
+ data.getString("isp") + ")";
Log.e("提示", "您的IP地址是：" + IP);
}
else
{
IP = "";
Log.e("提示", "IP接口异常，无法获取IP地址！");
}
}
else
{
IP = "";
Log.e("提示", "网络连接异常，无法获取IP地址！");
}
}
catch (Exception e)
{
IP = "";
Log.e("提示", "获取IP地址时出现异常，异常信息是：" + e.toString());
}
return IP;
}
Android 获取wifi的IP地址
WifiManager wifimanage=(WifiManager)context.getSystemService(Context.WIFI_SERVICE);//获取WifiManager
//检查wifi是否开启
if(!wifimanage.isWifiEnabled()) {
wifimanage.setWifiEnabled(true);
}
WifiInfo wifiinfo= wifimanage.getConnectionInfo();
String ip=intToIp(wifiinfo.getIpAddress());
//将获取的int转为真正的ip地址,参考的网上的，修改了下
private String intToIp(int i) {
return (i & 0xFF)+ "." + ((i >> 8 ) & 0xFF)? + "." + ((i >> 16 ) & 0xFF) +"."+((i >> 24 ) & 0xFF );
}
OK,这样就好了吗？呵呵，别忘记加上权限
<uses -permission="" android:name="android.permission.ACCESS_WIFI_STATE"></uses> <uses -permission="" android:name="adnroid.permission.CHANGE_WIFI_STATE"></use
android开发 获取WIFI和有线的IP地址
首先设置权限：
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission> <uses-permission android:name="android.permission.WAKE_LOCK"></uses-permission>
/**
* if (intf.getName().toLowerCase().equals("eth0") || intf.getName().toLowerCase().equals("wlan0"))
* 表示:仅过滤无线和有线的ip. networkInterface是有很多的名称的
* 比如sim0,remt1.....等等.我不需要用到就直接过滤了
*
* if (!ipaddress.contains("::"))
* 表示: 过滤掉ipv6的地址.不管无线还是有线 都有这个地址,
* 我这边显示地址大体是:fe80::288:88ff:fe00:1%eth0 fe80::ee17:2fff:fece:c0b4%wlan0
* 一般都是出现在第一次循环.第二次循环就是真正的ipv4的地址.
*
* @return
* @throws SocketException
