Android编程实现获取当前连接wifi名字的方法

WifiManager wifiMgr = (WifiManager) mActivity.getSystemService(Context.WIFI_SERVICE); int wifiState = wifiMgr.getWifiState(); WifiInfo info = wifiMgr.getConnectionInfo(); String wifiId = info != null ? info.getSSID() : null;public static InetAddress getWifiIp() { Context myContext = Globals.getContext(); if (myContext == null) {  throw new NullPointerException("Global context is null"); } WifiManager wifiMgr = (WifiManager) myContext.getSystemService(Context.WIFI_SERVICE); if (isWifiEnabled()) {  int ipAsInt = wifiMgr.getConnectionInfo().getIpAddress();  if (ipAsInt == 0) {  return null;  } else {  return Util.intToInet(ipAsInt);  } } else {  return null; } }// 取得wifi的ip地址InetAddress address = FTPServerService.getWifiIp();address.getHostAddress();public static boolean isWifiEnabled() { Context myContext = Globals.getContext(); if (myContext == null) {  throw new NullPointerException("Global context is null"); } WifiManager wifiMgr = (WifiManager) myContext.getSystemService(Context.WIFI_SERVICE); if (wifiMgr.getWifiState() == WifiManager.WIFI_STATE_ENABLED) {  ConnectivityManager connManager = (ConnectivityManager) myContext   .getSystemService(Context.CONNECTIVITY_SERVICE);  NetworkInfo wifiInfo = connManager   .getNetworkInfo(ConnectivityManager.TYPE_WIFI);  return wifiInfo.isConnected(); } else {  return false; } }// 打开wifi设置的页面Intent intent = new Intent(android.provider.Settings.ACTION_WIFI_SETTINGS);startActivity(intent);
