如何使用Java在Android Wi-Fi连接上设置代理设置和代理属性?
如何使用Java(编程方式)在Android Wi-Fi连接上设置代理设置和代理属性 由于iPassign、linkProperties、ProxySettings和ProxyProperties是Android 3.1及更高版本上WifiConfiguration中的隐藏字段,因此我需要能够枚举类并使用这些字段 在使用下面链接的代码示例之后,我可以为特定的Wi-Fi连接设置静态IP地址、网关和DNS,但我还需要设置Wificonfiguration.ProxySettings.static和ProxyProperties 请参阅堆栈溢出问题 比如说,如何使用Java在Android Wi-Fi连接上设置代理设置和代理属性?,android,wifimanager,Android,Wifimanager,如何使用Java(编程方式)在Android Wi-Fi连接上设置代理设置和代理属性 由于iPassign、linkProperties、ProxySettings和ProxyProperties是Android 3.1及更高版本上WifiConfiguration中的隐藏字段,因此我需要能够枚举类并使用这些字段 在使用下面链接的代码示例之后,我可以为特定的Wi-Fi连接设置静态IP地址、网关和DNS,但我还需要设置Wificonfiguration.ProxySettings.static和P
WifiConfiguration config = new WifiConfiguration(configuration);
config.ipAssignment = WifiConfiguration.IpAssignment.UNASSIGNED;
config.proxySettings = WifiConfiguration.ProxySettings.STATIC;
config.linkProperties.setHttpProxy(new ProxyProperties("127.0.0.1", 3128, ""));
寻找类似于:
setProxySettings("STATIC", wifiConf);
setProxyProperties("proxyserver.mine.com.au", 8080, ""); // Set Proxy server and port.
wifiManager.updateNetwork(wifiConf); //apply the setting
使用coolypf.ipAssignment.ProxySettings和linkProperties中的以下代码将隐藏
WifiManager manager = (WifiManager)getSystemService(Context.WIFI_SERVICE);
manager.asyncConnect(this, new Handler());
if (!manager.isWifiEnabled()) return;
List<WifiConfiguration> configurationList = manager.getConfiguredNetworks();
WifiConfiguration configuration = null;
int cur = manager.getConnectionInfo().getNetworkId();
for (int i = 0; i < configurationList.size(); ++i)
{
WifiConfiguration wifiConfiguration = configurationList.get(i);
if (wifiConfiguration.networkId == cur)
configuration = wifiConfiguration;
}
if (configuration == null) return;
WifiConfiguration config = new WifiConfiguration(configuration);
config.ipAssignment = WifiConfiguration.IpAssignment.UNASSIGNED;
config.proxySettings = WifiConfiguration.ProxySettings.STATIC;
config.linkProperties.clear();
config.linkProperties.setHttpProxy(new ProxyProperties("127.0.0.1", 3128, ""));
manager.saveNetwork(config);
WifiManager=(WifiManager)getSystemService(Context.WIFI_服务);
asyncConnect(这是一个新的处理程序());
如果(!manager.isWifiEnabled())返回;
List configurationList=manager.getConfiguredNetworks();
WifiConfiguration配置=null;
int cur=manager.getConnectionInfo().getNetworkId();
对于(int i=0;i
以下是一些允许您设置/取消设置代理属性的代码。它使用了上面链接中的一些相同代码。这些设置似乎在断开/重新连接时不起作用
