我认为我应该使用 NetworkInterface::getDisplayName。我有一些名字，但是当我选择要连接的网络时，这个名字与我看到的这个名字不同。

android.net.wifi.WifiInfo.getSSID?

WifiManager wifiMgr = (WifiManager) getActivity().getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiMgr.getConnectionInfo();
String name = wifiInfo.getSSID();

public String getWifiName(Context context) {
    WifiManager manager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
    if (manager.isWifiEnabled()) {
       WifiInfo wifiInfo = manager.getConnectionInfo();
       if (wifiInfo != null) {
          DetailedState state = WifiInfo.getDetailedStateOf(wifiInfo.getSupplicantState());
          if (state == DetailedState.CONNECTED || state == DetailedState.OBTAINING_IPADDR) {
              return wifiInfo.getSSID();
          }
       }
    }
    return null;
}

这（来自 Marakana 和其他人的各种答案的混合和匹配）将同时获得您想要从中提取的所有内容：

  1. 范围内的所有 wifi 路由器
  2. 连接wifi路由器

  3. 所有存储的 wifi 网络（在您的设备上）

    public String getCurrentSsid(Context context) {

  String ssid = null;
  ConnectivityManager connManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
  NetworkInfo networkInfo = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
  if (networkInfo.isConnected()) {
    final WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
    final WifiInfo connectionInfo = wifiManager.getConnectionInfo();
    if (connectionInfo != null && !(connectionInfo.getSSID().equals(""))) {
        //if (connectionInfo != null && !StringUtil.isBlank(connectionInfo.getSSID())) {
      ssid = connectionInfo.getSSID();
    }
 // Get WiFi status MARAKANA
    WifiInfo info = wifiManager.getConnectionInfo();
    String textStatus = "";
    textStatus += "\n\nWiFi Status: " + info.toString();
    String BSSID = info.getBSSID();
    String MAC = info.getMacAddress();

    List<ScanResult> results = wifiManager.getScanResults();
    ScanResult bestSignal = null;
    int count = 1;
    String etWifiList = "";
    for (ScanResult result : results) {
        etWifiList += count++ + ". " + result.SSID + " : " + result.level + "\n" +
                result.BSSID + "\n" + result.capabilities +"\n" +
                "\n=======================\n";
    }
    Log.v(TAG, "from SO: \n"+etWifiList);

    // List stored networks
    List<WifiConfiguration> configs = wifiManager.getConfiguredNetworks();
    for (WifiConfiguration config : configs) {
        textStatus+= "\n\n" + config.toString();
    }
    Log.v(TAG,"from marakana: \n"+textStatus);
  }
  return ssid;
}

免责声明：虽然这是工作代码，而不是伪代码，但它的唯一目的是说明从 wifi 连接中提取数据的方法，并且在使用前应该对其进行调整（和清理）。

简单到 2 行

WifiManager w=(WifiManager)getSystemService(Context.WIFI_SERVICE);
String wifi=w.getConnectionInfo().getSSID();

记得把它放在你的清单中

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
