在进行BLE扫描过滤时，可以使用Android的BluetoothLeScanner类来实现。以下是一个示例代码，演示如何按服务数据UUID进行BLE扫描过滤：

import android.bluetooth.BluetoothAdapter;
import android.bluetooth.BluetoothDevice;
import android.bluetooth.le.BluetoothLeScanner;
import android.bluetooth.le.ScanCallback;
import android.bluetooth.le.ScanFilter;
import android.bluetooth.le.ScanResult;
import android.bluetooth.le.ScanSettings;
import android.os.Handler;
import android.os.ParcelUuid;

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

public class BleScanner {
    private BluetoothLeScanner mBluetoothLeScanner;
    private ScanCallback mScanCallback;
    private Handler mHandler;

    public BleScanner() {
        mHandler = new Handler();
    }

    public void startScan(UUID serviceUuid) {
        BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
        mBluetoothLeScanner = bluetoothAdapter.getBluetoothLeScanner();

        ScanFilter scanFilter = new ScanFilter.Builder()
                .setServiceUuid(new ParcelUuid(serviceUuid))
                .build();

        List filters = new ArrayList<>();
        filters.add(scanFilter);

        ScanSettings scanSettings = new ScanSettings.Builder()
                .setScanMode(ScanSettings.SCAN_MODE_LOW_LATENCY)
                .build();

        mScanCallback = new ScanCallback() {
            @Override
            public void onScanResult(int callbackType, ScanResult result) {
                super.onScanResult(callbackType, result);
                BluetoothDevice device = result.getDevice();
                // 处理发现的设备
            }

            @Override
            public void onBatchScanResults(List results) {
                super.onBatchScanResults(results);
                // 处理批量扫描结果
            }

            @Override
            public void onScanFailed(int errorCode) {
                super.onScanFailed(errorCode);
                // 处理扫描失败
            }
        };

        mHandler.postDelayed(new Runnable() {
            @Override
            public void run() {
                mBluetoothLeScanner.stopScan(mScanCallback);
            }
        }, 10000); // 扫描10秒后自动停止

        mBluetoothLeScanner.startScan(filters, scanSettings, mScanCallback);
    }

    public void stopScan() {
        if (mBluetoothLeScanner != null && mScanCallback != null) {
            mBluetoothLeScanner.stopScan(mScanCallback);
        }
    }
}

上述代码首先获取默认的蓝牙适配器和BluetoothLeScanner实例。然后，创建一个ScanFilter对象，通过setServiceUuid方法设置服务数据的UUID。接下来，创建一个ScanSettings对象，设置扫描模式为SCAN_MODE_LOW_LATENCY（低延迟模式）。然后，创建一个ScanCallback对象，重写其中的方法以处理扫描结果。最后，通过startScan方法启动BLE扫描，通过stopScan方法停止扫描。

使用时，可以实例化BleScanner类，并调用startScan方法开始扫描，传入要过滤的服务数据UUID。
