Question

我正在尝试创建自己的wifi屏幕，其中向用户显示可点击的AP列表。问题是，当用户点击AP时，设备断开连接，然后重新连接到同一AP而不是所选AP。这是代码:(只有开放网络部分，我正试图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;
                    }
                }

我正试图从安全网络转移到开放网络

此处必须先更改配置，因此最好创建一个新配置：

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

并且您还需要先检查是否启用了wifi：

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

您还必须在wifiManager之后使用saveConfiguration()将当前更改保存到reconnect()：

wifiManager.saveConfiguration();

所以，整个方式必须是：

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;
   }
}

我最终使用ScanResult代替WifiConfiguration并创建了一个新配置 - 配置了所需的扫描结果，如下所示：

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();
