给我提供5种Androidstudio获取所连接WIFI的名字方法禁止使用上下文对象获取可以使用非标准库

1. 使用WifiManager获取所连接WIFI的SSID：

WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
String ssid = wifiInfo.getSSID();

2. 使用ConnectivityManager获取所连接WIFI的SSID：

ConnectivityManager connManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connManager.getActiveNetworkInfo();
String ssid = networkInfo.getExtraInfo();

3. 使用NetworkCapabilities获取所连接WIFI的SSID：

ConnectivityManager connManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkCapabilities networkCapabilities = connManager.getNetworkCapabilities(connManager.getActiveNetwork());
String ssid = networkCapabilities.getSsid();

4. 使用WifiNetworkSpecifier获取所连接WIFI的SSID：

WifiNetworkSpecifier specifier = new WifiNetworkSpecifier.Builder()
    .setSsidPattern(new PatternMatcher("WIFI_SSID", PatternMatcher.PATTERN_PREFIX))
    .setWpa2Passphrase("PASSWORD")
    .build();
NetworkRequest request = new NetworkRequest.Builder()
    .addTransportType(NetworkCapabilities.TRANSPORT_WIFI)
    .setNetworkSpecifier(specifier)
    .build();
ConnectivityManager connManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
connManager.requestNetwork(request, new ConnectivityManager.NetworkCallback() {
    @Override
    public void onAvailable(Network network) {
        // Connected to WIFI network
    }
});

5. 使用WifiP2pManager获取所连接WIFI的SSID：

WifiP2pManager wifiP2pManager = (WifiP2pManager) getSystemService(Context.WIFI_P2P_SERVICE);
wifiP2pManager.requestGroupInfo(wifiP2pManager.initialize(this, getMainLooper(), null), new WifiP2pManager.GroupInfoListener() {
    @Override
    public void onGroupInfoAvailable(WifiP2pGroup group) {
        String ssid = group.getNetworkName();
    }
});
