How to get name of wifi-network out of android using android API?
提问by noisy
I thought that I should use NetworkInterface::getDisplayName. I got some name, but this name is different that this name which I can see, when I choosing to which network I want to connect.
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，这个名字与我可以看到的这个名字不同。
Please help..
请帮忙..

acording to Loxley answer:
根据 Loxley 的回答：
WifiManager wifiMgr = (WifiManager) getActivity().getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiMgr.getConnectionInfo();
String name = wifiInfo.getSSID();
采纳答案by Loxley
android.net.wifi.WifiInfo.getSSID?
android.net.wifi.WifiInfo.getSSID?
回答by sergey.n
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;
}

This (mix and match of various answers from Marakana and others) will simultaneously get everything you want to extract from:
这（混合和匹配来自 Marakana 和其他人的各种答案）将同时获得您想要从中提取的所有内容：
- all wifi routers in range
- connected wifi router
all stored wifi networks (on your device)
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; }
- 范围内的所有 wifi 路由器
- 连接的wifi路由器
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; }
DISCLAIMER: while this is working code, not pseudo code, its only purpose is to illustrate the methods for data extraction from wifi connections and it should be adapted (and cleaned) before use.
免责声明：虽然这是工作代码，而不是伪代码，但其唯一目的是说明从 wifi 连接中提取数据的方法，应在使用前进行调整（和清理）。
