java - Android 网络未添加到 Wifi 列表

Question

我正在使用一个函数将网络添加到 wifi 列表:

 public void connecttowifi(String networkSSID, String networkPass) {
        try {
            WifiConfiguration conf = new WifiConfiguration();
            conf.SSID = "\"" + networkSSID + "\"";
            conf.preSharedKey = "\""+ networkPass +"\"";
            conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
            WifiManager wifiManager = (WifiManager)getSystemService(Context.WIFI_SERVICE);
            wifiManager.addNetwork(conf);
            List<WifiConfiguration> list = wifiManager.getConfiguredNetworks();
            for( WifiConfiguration i : list ) {
                if(i.SSID != null && i.SSID.equals("\"" + networkSSID + "\"")) {
                    wifiManager.disconnect();
                    wifiManager.enableNetwork(i.networkId, true);
                    wifiManager.reconnect();

                    break;
                }
            }

        } catch (Exception ex) {
            Log.d("Wifi exception is",ex.toString());
        }
    }

在 MainActivity.java 中我写道:

 connecttowifi("333","333");

网络未添加，未发现异常，有什么帮助吗？

也许你可以登录循环

打印所有已配置网络的 SSID

我猜这就是问题所在:

if(i.SSID != null && i.SSID.equals("\"" + networkSSID + "\""))

把“\”去掉到下面

if(i.SSID != null && i.SSID.equals(networkSSID))

希望这有帮助!!
