Android通过名称以编程方式连接到Open WiFi – 这是最佳解决方案？
我一直试图使用两种方法按名称以编程方式连接到开放的wifi（连接门户）。
我使用op1，但它只能使用80％的次数。

op1：
public static void connectToWifi(Context context, String networkSSID) { WifiConfiguration conf = new WifiConfiguration(); conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE); wifiManager.addNetwork(conf); List list = wifiManager.getConfiguredNetworks(); for (WifiConfiguration i : list) { Log.d(TAG + " |connectToWifi()", "i.SSID=> " + i.SSID); if (i.SSID != null && i.SSID.equals("\"" + networkSSID + "\"")) { wifiManager.disconnect(); wifiManager.enableNetwork(i.networkId, true); wifiManager.reconnect(); Log.d(TAG + " |connectToWifi()", "IF > i.SSID=> " + i.SSID); break; }else {Log.e(TAG + " |connectToWifi()", "ELSE - FAILED TO CONNECT > i.SSID=> " + i.SSID);} } }//end connectToWifi op2：来自https://stackoverflow.com/a/8818490/3792198
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE); wifiManager.addNetwork(conf); List 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; } }
OP3：
WifiConfiguration wifiConfig = new WifiConfiguration(); wifiConfig.SSID = String.format("\"%s\"", ssid); wifiConfig.preSharedKey = String.format("\"%s\"", key); WifiManager wifiManager = (WifiManager)getSystemService(WIFI_SERVICE); //remember id int netId = wifiManager.addNetwork(wifiConfig); wifiManager.disconnect(); wifiManager.enableNetwork(netId, true); wifiManager.reconnect();
或者，你有什么建议吗？ 谢谢

调用方法
ConnectionManager connectionManager=new ConnectionManager(context); connectionManager.enableWifi(); connectionManager.requestWIFIConnection("YOUR_SSID","PASSWORD");
