我需要在android中生成带有UPC A格式标签的条形码图像

implementation 'com.google.zxing:core:3.4.1'
implementation 'com.journeyapps:zxing-android-embedded:3.6.0'

import com.google.zxing.qrcode.decoder.ErrorCorrectionLevel;

public class BarcodeActivity extends AppCompatActivity {

    private ImageView barcodeImageView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_barcode);

        barcodeImageView = findViewById(R.id.barcode_image_view);

        String barcodeData = "123456789012"; // UPC A格式的条形码数据

        try {
            Bitmap barcodeBitmap = generateBarcode(barcodeData);
            barcodeImageView.setImageBitmap(barcodeBitmap);
        } catch (WriterException e) {
            e.printStackTrace();
        }
    }

    private Bitmap generateBarcode(String barcodeData) throws WriterException {
        Map<EncodeHintType, Object> hints = new EnumMap<>(EncodeHintType.class);
        hints.put(EncodeHintType.ERROR_CORRECTION, ErrorCorrectionLevel.L); // 设置纠错级别为L，可根据需求调整

        UPCAWriter barcodeWriter = new UPCAWriter();
        BitMatrix bitMatrix = barcodeWriter.encode(barcodeData, BarcodeFormat.UPC_A, 600, 300, hints);

        int width = bitMatrix.getWidth();
        int height = bitMatrix.getHeight();
        int[] pixels = new int[width * height];

        for (int y = 0; y < height; y++) {
            int offset = y * width;
            for (int x = 0; x < width; x++) {
                pixels[offset + x] = bitMatrix.get(x, y) ? 0xFF000000 : 0xFFFFFFFF; // 设置条码颜色，黑色和白色
            }
        }

        Bitmap barcodeBitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
        barcodeBitmap.setPixels(pixels, 0, width, 0, 0, width, height);

        return barcodeBitmap;
    }
}
