Android 擷取wifi的IP地址

WifiManager wifimanage=(WifiManager)context.getSystemService(Context.WIFI_SERVICE);//擷取WifiManager    //檢查wifi是否開啟    if(!wifimanage.isWifiEnabled())  {    　　wifimanage.setWifiEnabled(true);    }    WifiInfo wifiinfo= wifimanage.getConnectionInfo();    String ip=intToIp(wifiinfo.getIpAddress());    //將擷取的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，別忘記加上許可權    <uses -permission="" android:name="android.permission.ACCESS_WIFI_STATE"></uses>  <uses -permission="" android:name="adnroid.permission.CHANGE_WIFI_STATE"></use
