在Android10之后，如何检测WiFi连接/断开？

public class WifiBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();

        if (action.equals(WifiManager.NETWORK_STATE_CHANGED_ACTION)) {
            NetworkInfo networkInfo = intent.getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO);
            if (networkInfo != null && networkInfo.isConnected()) {
                // WiFi已连接
                // 执行相应操作
            }
        } else if (action.equals(WifiManager.WIFI_STATE_CHANGED_ACTION)) {
            int wifiState = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE, WifiManager.WIFI_STATE_UNKNOWN);
            if (wifiState == WifiManager.WIFI_STATE_DISABLED) {
                // WiFi已断开
                // 执行相应操作
            }
        }
    }
}

<receiver android:name=".WifiBroadcastReceiver">
    <intent-filter>
        <action android:name="android.net.wifi.STATE_CHANGE" />
        <action android:name="android.net.wifi.WIFI_STATE_CHANGED" />
    </intent-filter>
</receiver>

ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkCapabilities networkCapabilities = connectivityManager.getNetworkCapabilities(connectivityManager.getActiveNetwork());

if (networkCapabilities != null && networkCapabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)) {
    // WiFi已连接
    // 执行相应操作
} else {
    // WiFi已断开
    // 执行相应操作
}
