Android编程实现获取当前连接wifi名字的方法

本文实例讲述了Android编程实现获取当前连接wifi名字的方法。分享给大家供大家参考，具体如下：

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);

希望本文所述对大家Android程序设计有所帮助。
