如何通过通过代码来配置android11的默认wifi接入点

以下是一些示例代码，可以通过代码来配置Android 11的默认Wi-Fi接入点：

1. 设置Wi-Fi SSID和密码

WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
WifiConfiguration wifiConfig = new WifiConfiguration();
wifiConfig.SSID = "\"SSID\"";
wifiConfig.preSharedKey = "\"Password\"";
wifiManager.addNetwork(wifiConfig);

2. 连接Wi-Fi网络

WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
List<WifiConfiguration> wifiConfigs = wifiManager.getConfiguredNetworks();
for (WifiConfiguration wifiConfig : wifiConfigs) {
    if (wifiConfig.SSID != null && wifiConfig.SSID.equals("\"SSID\"")) {
        wifiManager.disconnect();
        wifiManager.enableNetwork(wifiConfig.networkId, true);
        wifiManager.reconnect();
        break;
    }
}

3. 设置默认的Wi-Fi接入点

ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkRequest.Builder builder = new NetworkRequest.Builder();
builder.addTransportType(NetworkCapabilities.TRANSPORT_WIFI);
builder.addCapability(NetworkCapabilities.NET_CAPABILITY_NOT_RESTRICTED);
builder.setNetworkSpecifier(new WifiNetworkSpecifier.Builder().setSsid("SSID").setWpa2Passphrase("Password").build());
connectivityManager.requestNetwork(builder.build(), new ConnectivityManager.NetworkCallback() {
    @Override
    public void onAvailable(Network network) {
        super.onAvailable(network);
        connectivityManager.bindProcessToNetwork(network);
    }
});

请注意，这些示例代码仅供参考，实际应用中可能需要根据具体情况进行调整。此外，需要在AndroidManifest.xml文件中添加相关权限，如下所示：

<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"/>
