如何通过单击已配置网络结果的列表视图上的项目来连接到 WIFI 网络

Question

我有一个通过wifiManager.getConfiguredNetworks（）方法配置的Wifi网络列表。我在列表视图中显示了它们。现在，无论我单击哪个列表项，它都仅连接到同一个网络。我想连接到被单击的网络。

这是我的Java代码

 listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                String networkSSID = list.get(position).SSID;
                String networkPass = list.get(position).preSharedKey;
               WifiConfiguration conf = new WifiConfiguration();
                conf.SSID = """ + networkSSID + """;
                conf.preSharedKey = """+ networkPass +""";
                int netId = wifiManager.addNetwork(conf);
                wifiManager.disconnect();
                wifiManager.enableNetwork(netId,true);
                wifiManager.reconnect();
            }
        });

我使用以下代码块

 private void connectToAP(String ssid, String passkey) {
    WifiManager wifiManager = (WifiManager) context.getSystemService(WIFI_SERVICE);
    Log.i(TAG, "* connectToAP");
    WifiConfiguration wifiConfiguration = new WifiConfiguration();
    List<ScanResult> scanResultList = wifiManager.getScanResults();

    for (ScanResult result : scanResultList) {
        if (result.SSID.equals(ssid)) {
            String securityMode = getScanResultSecurity(result);
            if (securityMode.equalsIgnoreCase("OPEN")) {
                wifiConfiguration.SSID = """ + ssid + """;
                wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
                int res = wifiManager.addNetwork(wifiConfiguration);
                Log.d(TAG, "# add Network returned " + res);
                boolean b = wifiManager.enableNetwork(res, true);
                Log.d(TAG, "# enableNetwork returned " + b);
                wifiManager.setWifiEnabled(true);
            } else if (securityMode.equalsIgnoreCase("WEP")) {
                wifiConfiguration.SSID = """ + ssid + """;
                wifiConfiguration.wepKeys[0] = """ + passkey + """;
                wifiConfiguration.wepTxKeyIndex = 0;
                wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
                wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
                int res = wifiManager.addNetwork(wifiConfiguration);
                Log.d(TAG, "### 1 ### add Network returned " + res);
                boolean b = wifiManager.enableNetwork(res, true);
                Log.d(TAG, "# enableNetwork returned " + b);
                wifiManager.setWifiEnabled(true);
            }
            wifiConfiguration.SSID = """ + ssid + """;
            wifiConfiguration.preSharedKey = """ + passkey + """;
            wifiConfiguration.hiddenSSID = true;
            wifiConfiguration.status = WifiConfiguration.Status.ENABLED;
            wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
            wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
            wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
            wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
            wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
            wifiConfiguration.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
            wifiConfiguration.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
            int res = wifiManager.addNetwork(wifiConfiguration);
            Log.d(TAG, "### 2 ### add Network returned " + res);
            wifiManager.enableNetwork(res, true);
            boolean changeHappen = wifiManager.saveConfiguration();
            if (res != -1 && changeHappen) {
                Log.d(TAG, "### Change happen");

            } else {
                Log.d(TAG, "*** Change NOT happen");
            }
            wifiManager.setWifiEnabled(true);
        }
    }
}
