Android获取当前连接的wifi名称

首先AndroidMainfest.xml文件里加入权限：

<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();
	}
