Question

我正在尝试创建自己的 wifi 屏幕，其中会向用户显示可点击 AP 的列表。问题是，当用户单击 AP 时，设备会断开连接，然后重新连接到同一个 AP 而不是所选的 AP。这是代码：（只有开放网络部分，我正在尝试从安全网络转移到开放网络）

         public void onClick(View v) {
                WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
                List<WifiConfiguration> configuredNetworks = wifiManager.getConfiguredNetworks();
                for (WifiConfiguration configuredNetwork : configuredNetworks) {
                    if (currSSID().equals(configuredNetwork.SSID)) { // I took care of the removel of the "" in configuredNetwork.SSID in my code  
                        configuredNetwork .allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
                        wifiManager.disconnect();
                        wifiManager.enableNetwork(configuredNetwork.networkId, true);
                        wifiManager.reconnect();
                        break;
                    }
                }

I'm trying to move from secured network to an open one

这里的配置之前必须改过，所以最好新建一个：

WifiConfiguration conf = new WifiConfiguration();
conf.SSID = "\"" + your_net_name + "\"";
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);

另外你还需要先检查wifi是否开启:

if(!wifiManager.isWifiEnabled()){
    wifiManager.setWifiEnabled(true);
}

您还必须在 reconnect():

之后使用 saveConfiguration() 将当前更改保存到 wifiManager

wifiManager.saveConfiguration();

所以，整个路一定是：

public void onClick(View v) {
WifiConfiguration conf = new WifiConfiguration();
conf.SSID = "\"" + your_net_name + "\"";
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
if(!wifiManager.isWifiEnabled()){
    wifiManager.setWifiEnabled(true);
}
List<WifiConfiguration> configuredNetworks = wifiManager.getConfiguredNetworks();
for (WifiConfiguration configuredNetwork : configuredNetworks) {
     if (currSSID().equals(configuredNetwork.SSID)) { // I took care of the removel of the "" in configuredNetwork.SSID in my code  
        //configuredNetwork .allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); // you don't need it here
        wifiManager.disconnect();
        wifiManager.enableNetwork(configuredNetwork.networkId, true);
        wifiManager.reconnect();
        wifiManager.saveConfiguration(); // to save your new changes to the network
        break;
   }
}

Answer 2

我最终使用 ScanResult 而不是 WifiConfiguration 并创建了一个新的配置 - 与想要的扫描结果进行如下配置：

conf.SSID = "\"" + scanResult.SSID + "\"";
conf.BSSID = scanResult.BSSID;
conf.hiddenSSID = true;
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
int id = wifiManager.addNetwork(conf);
wifiManager.disconnect();
wifiManager.enableNetwork(id, true);
wifiManager.reconnect();
wifiManager.saveConfiguration();
