从android和java连接到wifi，enableNetwork始终返回true

Question

我做了研究，但我找不到解决问题的方法，实际上我不知道我做错了什么但是enableNetwork总是返回true，甚至reconnect（）方法总是返回true，这很奇怪，甚至当错误的密码通过时..你能指点我正确的方向吗？我只是想检查wifi连接的特定密码。这是正确的方法吗？

      WifiConfiguration conf = new WifiConfiguration();
                                    conf.preSharedKey = "\""+ networkPass +"\"";
                                    WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);
                                    int res = wifi.addNetwork(conf);
                                    wifiManager.disconnect();
                                    boolean b = wifiManager.enableNetwork(res, true);
                                    String str = String.valueOf(b);
                                    Toast.makeText(getApplicationContext(), str, Toast.LENGTH_LONG).show();

                                    if (wifiManager.reconnect()) {
                                        Toast.makeText(getApplicationContext(), "Connected", Toast.LENGTH_LONG).show();

                                    } else {
                                        Toast.makeText(getApplicationContext(), "Not Connected", Toast.LENGTH_LONG).show();
                                    }
