当热点打开或连接到wifi网络或通过蓝牙时,我需要我的Android手机的本地IP地址。
我已经使用了这两个代码
第一个代码给出" 10.0.2.5"在所有情况下和第二个在连接到wifi网络时给出正确的IP地址。但是当热点开启时,它会给出" 0.0.0.0"
FIRST代码段
public static String getIpAddress() {
try {
for (Enumeration en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
NetworkInterface intf = (NetworkInterface) en.nextElement();
for (Enumeration enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
InetAddress inetAddress = (InetAddress) enumIpAddr.nextElement();
if (!inetAddress.isLoopbackAddress()&&inetAddress instanceof Inet4Address) {
String ipAddress=inetAddress.getHostAddress().toString();
Log.e("IP address",""+ipAddress);
return ipAddress;
}
}
}
} catch (SocketException ex) {
Log.e("MASOOM", ex.toString());
}
return null;
}
第二个代码段
public String getIpAddress(){
WifiManager wifiManager = (WifiManager) this.getSystemService(WIFI_SERVICE);
int ipAddress = wifiManager.getConnectionInfo().getIpAddress();
return String.format("%d.%d.%d.%d", (ipAddress & 0xff), (ipAddress >> 8 & 0xff),(ipAddress >> 16 & 0xff), (ipAddress >> 24 & 0xff));
}
请提供正确的代码
答案 0 :(得分:0)
String ip = "";
try {
Enumeration<NetworkInterface> enumNetworkInterfaces = NetworkInterface.getNetworkInterfaces();
while (enumNetworkInterfaces.hasMoreElements()) {
NetworkInterface networkInterface = enumNetworkInterfaces.nextElement();
Enumeration<InetAddress> enumInetAddress = networkInterface.getInetAddresses();
while (enumInetAddress.hasMoreElements()) {
InetAddress inetAddress = enumInetAddress.nextElement();
if (inetAddress.isSiteLocalAddress()) {
ip += inetAddress.getHostAddress() + " | ";
}
}
}
} catch (SocketException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return ip;
