android 中连接wifi代码

以下是一个Android连接WiFi的示例代码：

private void connectToWiFi(String networkSSID, String networkPasskey) {
    WifiConfiguration wifiConfig = new WifiConfiguration();
    wifiConfig.SSID = "\"" + networkSSID + "\"";
    wifiConfig.preSharedKey = "\"" + networkPasskey + "\"";

    WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
    int networkId = wifiManager.addNetwork(wifiConfig);

    if (networkId != -1) {
        wifiManager.disconnect();
        wifiManager.enableNetwork(networkId, true);
        wifiManager.reconnect();
    }
}

该方法接受两个参数：网络名称（SSID）和网络密码（Passkey）。它使用这两个值创建一个新的WiFiConfiguration对象，将其添加到WIFiManager中，并使用enableNetwork()方法连接到网络。请注意，使用此方法时需要获得适当的权限
