Android10 framework开发设置WiFi静态模式

要设置WiFi静态模式，您需要在Android 10的framework代码中进行以下步骤：

1. 打开WifiManager.java文件并添加以下代码：

/**
 * Set the IP address, gateway, and subnet mask for a static IP configuration.
 *
 * @param ipAddress the IP address in integer form
 * @param gateway the gateway in integer form
 * @param subnetMask the subnet mask in integer form
 * @param dns the DNS server addresses in integer form
 * @return {@code true} if the operation succeeded, {@code false} otherwise
 * @hide
 */
public boolean setWifiStaticIpConfiguration(int ipAddress, int gateway, int subnetMask, int[] dns) {
    WifiConfiguration config = getCurrentWifiConfiguration();
    if (config == null) {
        return false;
    }
    config.setIpAssignment(IpAssignment.STATIC);
    config.setIpAddress(InetAddress.getByAddress(intToByteArray(ipAddress)).getHostAddress());
    config.setGateway(InetAddress.getByAddress(intToByteArray(gateway)).getHostAddress());
    config.setNetmask(InetAddress.getByAddress(intToByteArray(subnetMask)).getHostAddress());
    config.setDns(dns);
    return saveWifiConfiguration(config);
}

private byte[] intToByteArray(int value) {
    return new byte[] {
            (byte)(value >>> 24),
            (byte)(value >>> 16),
            (byte)(value >>> 8),
            (byte)value};
}

2. 在WifiConfiguration.java文件中，添加以下代码：

/**
 * Set the IP assignment mode.
 *
 * @param ipAssignment the IP assignment mode to set
 * @hide
 */
public void setIpAssignment(IpAssignment ipAssignment) {
    mIpAssignment = ipAssignment;
}

/**
 * Set the IP address.
 *
 * @param ipAddress the IP address to set
 * @hide
 */
public void setIpAddress(String ipAddress) {
    mIpAddress = ipAddress;
}

/**
 * Set the gateway.
 *
 * @param gateway the gateway to set
 * @hide
 */
public void setGateway(String gateway) {
    mGateway = gateway;
}

/**
 * Set the subnet mask.
 *
 * @param netmask the subnet mask to set
 * @hide
 */
public void setNetmask(String netmask) {
    mNetmask = netmask;
}

/**
 * Set the DNS server addresses.
 *
 * @param dns the DNS server addresses to set
 * @hide
 */
public void setDns(int[] dns) {
    mDnsServers.clear();
    for (int i = 0; i < dns.length; i++) {
        mDnsServers.add(InetAddress.getByAddress(intToByteArray(dns[i])));
    }
}

3. 最后，在Settings app中添加WiFi的静态IP配置。打开WifiSettings.java文件并添加以下代码：

/**
 * Show the dialog for configuring a static IP address.
 *
 * @param config the WifiConfiguration to configure
 * @hide
 */
public void showWifiStaticIpConfigDialog(WifiConfiguration config) {
    StaticIpConfigDialogFragment fragment = StaticIpConfigDialogFragment.newInstance(config);
    fragment.show(getFragmentManager(), StaticIpConfigDialogFragment.TAG);
}

这些代码将允许您在Android 10中设置WiFi的静态IP地址。
