所需权限

android.permission.ACCESS_WIFI_STATE
android.permission.CHANGE_WIFI_STATE

代码

        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);
