安卓开发Wifi连接功能，连接wifi的时候设置静态IP

好的，下面是在Android应用程序中实现WiFi连接并设置静态IP地址的步骤：

1. 首先，您需要在AndroidManifest.xml文件中添加以下权限：

<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"/>

2. 在您的Activity或Fragment中，定义以下变量：

WifiManager wifiManager;
WifiConfiguration wifiConfiguration;

3. 初始化WifiManager：

wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);

4. 搜索可用的WiFi网络并连接：

WifiInfo wifiInfo = wifiManager.getConnectionInfo();
List<ScanResult> scanResults = wifiManager.getScanResults();
for (ScanResult scanResult : scanResults) {
    if (scanResult.SSID.equals("您要连接的WiFi名称")) {
        String securityMode = getSecurityMode(scanResult);
        wifiConfiguration = new WifiConfiguration();
        wifiConfiguration.SSID = "\"" + scanResult.SSID + "\"";
        if (securityMode.equals("OPEN")) {
            wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
        } else if (securityMode.equals("WEP")) {
            wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
            wifiConfiguration.wepKeys[0] = "\"" + "您的WiFi密码" + "\"";
            wifiConfiguration.wepTxKeyIndex = 0;
        } else if (securityMode.equals("PSK")) {
            wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
            wifiConfiguration.preSharedKey = "\"" + "您的WiFi密码" + "\"";
        }
        int networkId = wifiManager.addNetwork(wifiConfiguration);
        wifiManager.disconnect();
        wifiManager.enableNetwork(networkId, true);
        wifiManager.reconnect();
        break;
    }
}

5. 实现获取WiFi网络的安全模式：

public String getSecurityMode(ScanResult scanResult) {
    String securityMode = "OPEN";
    if (scanResult.capabilities.contains("WEP")) {
        securityMode = "WEP";
    } else if (scanResult.capabilities.contains("PSK")) {
        securityMode = "PSK";
    }
    return securityMode;
}

6. 设置静态IP地址：

WifiConfiguration wifiConfiguration = new WifiConfiguration();
wifiConfiguration.ipAssignment = WifiConfiguration.IpAssignment.STATIC;
wifiConfiguration.gateway = "网关地址";
wifiConfiguration.ipAddress = InetAddress.getByName("静态IP地址").hashCode();
wifiConfiguration.netmask = InetAddress.getByName("子网掩码").hashCode();
wifiConfiguration.dns1 = InetAddress.getByName("首选DNS服务器地址").hashCode();
wifiConfiguration.dns2 = InetAddress.getByName("备用DNS服务器地址").hashCode();
wifiManager.updateNetwork(wifiConfiguration);
wifiManager.saveConfiguration();
wifiManager.reconnect();

7. 最后，您需要在AndroidManifest.xml文件中添加以下权限：

<uses-permission android:name="android.permission.CHANGE_WIFI_MULTICAST_STATE"/>
<uses-permission android:name="android.permission.WRITE_SETTINGS"/>

到这里，您的应用程序就可以连接到WiFi并设置静态IP地址了。
