【问题描述】：

我创建了一个应用程序来连接到列表中选定的 Wifi。这在 4.1.2（网络 ID = 10）的 android 版本中运行良好，但如果我尝试在 4.4.2 和 4.4.4 版本上运行相同的应用程序，它会将网络 ID 值显示为 -1。

我的代码是：

private void connectToWifi2() {
    // TODO Auto-generated method stub

    // Main method. Write code here.
    WifiConfiguration conf = new WifiConfiguration();
    conf.SSID = String.format("\"%s\"", selWifi.SSID);
    conf.preSharedKey = String.format("\"%s\"", pwd.getText().toString());


    conf.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
    conf.status = WifiConfiguration.Status.ENABLED;
    conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
    conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_EAP);
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.IEEE8021X);
    conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
    conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
    conf.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
    conf.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_EAP);
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.IEEE8021X);

    conf.hiddenSSID = true;
    // remember id
    int netId = wifiManager.addNetwork(conf);
    Log.d("RMGWiFiConfig", "netId returned" + netId);
    if (netId >= 0) {
        Log.i("RMGWiFiConfig", "Connecting with " + selWifi.SSID);
        wifiManager.disconnect();
        Boolean statusInBoolean = wifiManager.enableNetwork(netId, true);
        Log.d("RMGWiFiConfig", "Enabled network returned "
                + statusInBoolean);
        Log.d("RMGWiFiConfig", "Reassociate : " + wifiManager.reassociate());
        Log.d("RMGWiFiConfig", "Reconnect " + wifiManager.reconnect());

    } else {
        Log.d("RMGWifiConfig", "Failed to add network configuration");
    }

}

我尝试参考以下链接但无法解决问题。或者我可能无法以以下链接中提供的正确方式适应解决方案。请让我知道我需要对我的代码进行的更改。

Can not connect another android device with wifi with android lollipop

Android WifiConfiguration shows -1 for ID. How can I fix it for SSID to be recognized?

Android 6.0 Cannot add WifiConfiguration if there is already another WifiConfiguration for that SSID

android wifiManager.addNetwork returns -1

WifiConfiguration enable network in Lollipop

Android 5.0 Lollipop and 4.4 KitKat ignores my WiFi network, enableNetwork() is useless

请帮忙！

谢谢修罗提

在此链接中，我找到了 enableNetwork() 的解决方案，但无法修复它。请帮忙 -stackoverflow.com/questions/26986023/…

【解决方案1】：

我找不到明显的关键原因，但我有类似的代码在 Android 6.x 上运行。我能找到的区别是：

wc.StatusField = WifiStatus.Disabled;（enableNetwork() 稍后会更新）
wc.PreSharedKey = "\"" + pw + "\"";
最后：wm.SaveConfiguration();

如果我不得不猜测，我会说这是导致失败的第一个原因。
