        WifiInfo wifiInfo = wifiManager.getConnectionInfo();

        String id = wifiInfo.getBSSID();

        String MAC = wifiInfo.getMacAddress();
        String SSID = wifiInfo.getSSID();
        int idnw = wifiInfo.getNetworkId();


            Log.v("ID", id);
            Log.v("IP", String.valueOf(ip));
            Log.v("MAC", MAC);
            Log.v("SSID", SSID);
            Log.v("idnw", String.valueOf(idnw));

推荐答案

您需要创建一个BroadcastReceiver来监听Wifi扫描结果:

You need to create a BroadcastReceiver to listen for Wifi scan results:

private final BroadcastReceiver mWifiScanReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context c, Intent intent) {
        if (intent.getAction() == WifiManager.SCAN_RESULTS_AVAILABLE_ACTION) {
            List<ScanResult> mScanResults = wifi.getScanResults();
            // add your logic here
        }
    }
}

在 onCreate() 中，您将分配 mWifiManager 并启动扫描:

In onCreate() you would assign mWifiManager and initiate a scan:

mWifiManager = (WifiManager)getSystemService(Context.WIFI_SERVICE);
mWifiManager.startScan();

每次有新的扫描结果可用时，都会运行此处理扫描结果的代码，更新结果.

This code which handles your scan results would run every time a new scan result is available, updating the result.
