Wi-Fi Scanner Android应用程序

Question

我创建了一个Android应用程序，显示可用网络列表，并在输入wifi密码后为我提供与特定WiFi网络的连接。但是我面临的问题是我的应用程序没有保留我给出的wifi密码保存。 我的申请代码如下：

 private void finallyConnect(String networkPass, String networkSSID) {
    WifiConfiguration wifiConfig = new WifiConfiguration();
    wifiConfig.SSID = String.format("\"%s\"", networkSSID);
    wifiConfig.preSharedKey = String.format("\"%s\"", networkPass);

    // remember id
    int netId = mainWifiObj.addNetwork(wifiConfig);
    mainWifiObj.disconnect();
    mainWifiObj.enableNetwork(netId, true);
    mainWifiObj.reconnect();

    WifiConfiguration conf = new WifiConfiguration();
    conf.SSID = "\"\"" + networkSSID + "\"\"";
    conf.preSharedKey = "\"" + networkPass + "\"";
    mainWifiObj.addNetwork(conf);
}

private void connectToWifi(final String wifiSSID) {
    final Dialog dialog = new Dialog(this);
    dialog.setContentView(R.layout.connect);
    dialog.setTitle("Connect to Network");
    TextView textSSID = (TextView) dialog.findViewById(R.id.textSSID1);

    Button dialogButton = (Button) dialog.findViewById(R.id.okButton);
    pass = (EditText) dialog.findViewById(R.id.textPassword);
    textSSID.setText(wifiSSID);

    // if button is clicked, connect to the network;
    dialogButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String checkPassword = pass.getText().toString();
            finallyConnect(checkPassword, wifiSSID);
            dialog.dismiss();
        }
    });
    dialog.show();

    findMyip();
