1、從搜索出來的列表中點擊某項，進行輸入密碼連接

   String wifiItemSSID = null;
        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            Log.i("ListOnItemClickListener", "start");
            selectedItem = arg1;
            String wifiItem = arrayWifiAdapter.getItem(arg2);// 獲得選中的設備
            wifiItemSSID = wifiItem;
            Log.i("ListOnItemClickListener", wifiItemSSID);
            SSID = wifiItemSSID;
            int wifiItemId = localWifiUtils.IsConfiguration("\"" + wifiItemSSID
                    + "\"");
            Log.i("ListOnItemClickListener", String.valueOf(wifiItemId));
            if (wifiItemId != -1) {
                if (localWifiUtils.ConnectWifi(wifiItemId)) {// 連接指定WIFI
                    Toast.makeText(ControlPCMainActivity.this,
                            "當前已連接" + wifiItemSSID, 0).show();
                    text_hint.setText("當前連接Wifi爲： " + wifiItemSSID);
                    SSID = wifiItemSSID;
                }
            } else {// 沒有配置好信息，配置
                WifiPswDialog pswDialog = new WifiPswDialog(
                        ControlPCMainActivity.this,
                        new OnCustomDialogListener() {
                            @Override
                            public void back(String str) {
                                // TODO Auto-generated method stub
                                wifiPassword = str;
                                if (wifiPassword != null) {
                                    int netId = localWifiUtils.AddWifiConfig(
                                            wifiResultList, wifiItemSSID,
                                            wifiPassword);
                                    Log.i("WifiPswDialog",
                                            String.valueOf(netId));
                                    // -1 表示 添加密碼信息失敗
                                    if (netId != -1) {
                                        localWifiUtils.getConfiguration();// 添加了配置信息，要重新得到配置信息
                                        if (localWifiUtils.ConnectWifi(netId)) {
                                            Toast.makeText(
                                                    ControlPCMainActivity.this,
                                                    "當前已連接" + wifiItemSSID, 0)
                                                    .show();
                                            text_hint.setText("當前連接Wifi爲： "
                                                    + wifiItemSSID);
                                            SSID = wifiItemSSID;
                                        }
                                    } else {
                                        Toast.makeText(
                                                ControlPCMainActivity.this,
                                                "網絡連接錯誤", Toast.LENGTH_SHORT)
                                                .show();
                                    }
                                } else {
                                }
                            }
                        });
                pswDialog.show();
            }
        }





    // 判定指定WIFI是否已經配置好,依據WIFI的地址BSSID,返回NetId
        public int IsConfiguration(String SSID) {
        Log.i("IsConfiguration", String.valueOf(wifiConfigList.size()));
        for (int i = 0; i < wifiConfigList.size(); i++) {
            Log.i(wifiConfigList.get(i).SSID,
                    String.valueOf(wifiConfigList.get(i).networkId));
            if (wifiConfigList.get(i).SSID.equals(SSID)) {// 地址相同
                return wifiConfigList.get(i).networkId;
            }
        }
        return -1;
    }

2、以上爲核心wifi連接的部分代碼，主要是獲取wifi配置信息，如果未配置，則添加配置信息並且添加如wifi。
