安卓实现wifi连接的同时设置静态IP以及代理

可以通过以下代码实现在 Android 设备上连接 WiFi 并设置静态 IP 和代理：

public void connectToWifiWithStaticIpAndProxy(String ssid, String password, String staticIp, String gateway, String subnetMask, String dns1, String dns2, String proxyHost, int proxyPort, String proxyUsername, String proxyPassword) {
    WifiConfiguration wifiConfiguration = new WifiConfiguration();
    wifiConfiguration.SSID = "\"" + ssid + "\"";
    wifiConfiguration.preSharedKey = "\"" + password + "\"";

    // 设置静态 IP
    try {
        InetAddress inetAddress = InetAddress.getByName(staticIp);
        InetAddress gatewayInetAddress = InetAddress.getByName(gateway);
        InetAddress dns1InetAddress = InetAddress.getByName(dns1);
        InetAddress dns2InetAddress = InetAddress.getByName(dns2);

        wifiConfiguration.setIpConfiguration(new IpConfiguration.Builder()
                .setStaticIpConfiguration(new StaticIpConfiguration.Builder()
                        .setIpAddress(new LinkAddress(inetAddress, 24))
                        .setGateway(gatewayInetAddress)
                        .setDnsServers(Arrays.asList(dns1InetAddress, dns2InetAddress))
                        .build())
                .build());
    } catch (Exception e) {
        e.printStackTrace();
    }

    // 设置代理
    ProxyInfo proxyInfo = null;
    if (!TextUtils.isEmpty(proxyHost)) {
        proxyInfo = new ProxyInfo(proxyHost, proxyPort, null);
        if (!TextUtils.isEmpty(proxyUsername) && !TextUtils.isEmpty(proxyPassword)) {
            proxyInfo = new ProxyInfo(proxyHost, proxyPort, proxyUsername, proxyPassword);
        }
    }
    wifiConfiguration.setHttpProxy(proxyInfo);

    // 连接 WiFi
    WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
    int networkId = wifiManager.addNetwork(wifiConfiguration);
    wifiManager.disconnect();
    wifiManager.enableNetwork(networkId, true);
    wifiManager.reconnect();
}

注意，需要在 AndroidManifest.xml 中添加以下权限：

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />
<uses-permission android:name="android.permission.INTERNET" />
