1.許可權:

 <!-- 獲取網絡卡MAC的許可權 -->
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" >
    </uses-permission>
    <!-- 開啟wifi的許可權 -->
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

2.方法:

private String getWifiMac() {


WifiManager manager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
int state = manager.getWifiState();
if (state != WifiManager.WIFI_STATE_ENABLED
&& state != WifiManager.WIFI_STATE_ENABLING) {
manager.setWifiEnabled(true);
}
WifiInfo info = manager.getConnectionInfo();
return info.getMacAddress();
}

3.經測試,可以順利拿到mac地址
