Android获取当前连接的wifi名称

首先AndroidMainfest.xml文件中添加权限：

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <!-- 获取WIFI信息状态的权限 -->        <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <!-- 获取网络状态改变的权限 -->  

    private String getConnectWifiSsid(){                   WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);                   WifiInfo wifiInfo = wifiManager.getConnectionInfo();                   Log.d("wifiInfo", wifiInfo.toString());                   Log.d("SSID",wifiInfo.getSSID());                   return wifiInfo.getSSID();            }
