Android 獲取wifi的IP地址

WifiManager wifimanage=(WifiManager)context.getSystemService(Context.WIFI_SERVICE);//獲取WifiManager  
  
//檢查wifi是否開啟  
  
if(!wifimanage.isWifiEnabled())  {  
  
　　wifimanage.setWifiEnabled(true);  
  
}  
  
WifiInfo wifiinfo= wifimanage.getConnectionInfo();  
  
String ip=intToIp(wifiinfo.getIpAddress());  
  
//將獲取的int轉為真正的ip地址,參考的網上的，修改了下  
  
private String intToIp(int i)  {
　　return (i & 0xFF)+ "." + ((i >> 8 ) & 0xFF)? + "." + ((i >> 16 ) & 0xFF) +"."+((i >> 24 ) & 0xFF );
}  
    

OK,這樣就好了嗎？呵呵，別忘記加上權限  
  
<uses -permission="" android:name="android.permission.ACCESS_WIFI_STATE"></uses>  

<uses -permission="" android:name="adnroid.permission.CHANGE_WIFI_STATE"></use
