您可以使用Android的BLE AdvertiseData构建器（AdvertiseData.Builder）来构建广告数据，并在回调执行时添加多个服务。以下是一个示例代码：

import android.bluetooth.BluetoothAdapter;
import android.bluetooth.le.AdvertiseCallback;
import android.bluetooth.le.AdvertiseData;
import android.bluetooth.le.AdvertiseSettings;
import android.bluetooth.le.BluetoothLeAdvertiser;
import android.os.ParcelUuid;

import java.util.ArrayList;
import java.util.List;
import java.util.UUID;

public class BLEAdvertiser {

    private BluetoothLeAdvertiser advertiser;
    private AdvertiseSettings settings;
    private AdvertiseData advertiseData;
    private AdvertiseCallback advertiseCallback;

    public void startAdvertising() {
        // 获取BluetoothLeAdvertiser实例
        advertiser = BluetoothAdapter.getDefaultAdapter().getBluetoothLeAdvertiser();

        // 设置广告的参数
        settings = new AdvertiseSettings.Builder()
                .setAdvertiseMode(AdvertiseSettings.ADVERTISE_MODE_LOW_LATENCY)
                .setConnectable(true)
                .setTimeout(0)
                .setTxPowerLevel(AdvertiseSettings.ADVERTISE_TX_POWER_HIGH)
                .build();

        // 创建一个AdvertiseData构建器
        AdvertiseData.Builder dataBuilder = new AdvertiseData.Builder();

        // 添加第一个服务UUID
        UUID serviceUuid1 = UUID.fromString("00001111-0000-1000-8000-00805f9b34fb");
        ParcelUuid parcelUuid1 = new ParcelUuid(serviceUuid1);
        dataBuilder.addServiceUuid(parcelUuid1);

        // 添加第二个服务UUID
        UUID serviceUuid2 = UUID.fromString("00002222-0000-1000-8000-00805f9b34fb");
        ParcelUuid parcelUuid2 = new ParcelUuid(serviceUuid2);
        dataBuilder.addServiceUuid(parcelUuid2);

        // 将AdvertiseData构建器构建为AdvertiseData对象
        advertiseData = dataBuilder.build();

        // 开始广告
        advertiser.startAdvertising(settings, advertiseData, advertiseCallback);
    }
}

在上面的示例中，我们首先获取BluetoothLeAdvertiser实例并设置广告的参数。然后，我们创建一个AdvertiseData.Builder对象，并使用addServiceUuid()方法添加多个服务UUID。最后，我们使用AdvertiseData.Builder的build()方法将构造的AdvertiseData对象传递给startAdvertising()方法来开始广告。

请注意，您需要在AndroidManifest.xml文件中声明BLUETOOTH_ADMIN和BLUETOOTH权限：

希望这对您有所帮助！
