Android获取当前连接wifi名字 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);
