Question

我想创建一个类似CamCard的应用，该应用将以ocr形式工作并将文本填充到特定字段中，我已经将Firebase MLKit用于图像中的文本识别器，但是问题是它现在为我提供了文本列表，如何获取与哪个字段相关的文本我的基本实现如下

 FirebaseApp.initializeApp(this);
        FirebaseVisionImage image = FirebaseVisionImage.fromBitmap(bm);



FirebaseVisionTextRecognizer textRecognizer = FirebaseVision.getInstance()
                .getOnDeviceTextRecognizer();
        textRecognizer.processImage(image)
                .addOnSuccessListener(new OnSuccessListener<FirebaseVisionText>() {
                    @Override
                    public void onSuccess(FirebaseVisionText result) {
                        // Task completed successfully
                        // ...
                        String resultText = result.getText();
                        for (FirebaseVisionText.TextBlock block : result.getTextBlocks()) {
                            String blockText = block.getText();
                            Float blockConfidence = block.getConfidence();
                            List<RecognizedLanguage> blockLanguages = block.getRecognizedLanguages();
                            Point[] blockCornerPoints = block.getCornerPoints();
                            Rect blockFrame = block.getBoundingBox();
                            for (FirebaseVisionText.Line line : block.getLines()) {
                                String lineText = line.getText();
                                Float lineConfidence = line.getConfidence();
                                List<RecognizedLanguage> lineLanguages = line.getRecognizedLanguages();
                                Point[] lineCornerPoints = line.getCornerPoints();
                                Rect lineFrame = line.getBoundingBox();
                                for (FirebaseVisionText.Element element : line.getElements()) {
                                    String elementText = element.getText();
                                    Float elementConfidence = element.getConfidence();
                                    List<RecognizedLanguage> elementLanguages = element.getRecognizedLanguages();
                                    Point[] elementCornerPoints = element.getCornerPoints();
                                    Rect elementFrame = element.getBoundingBox();
                                }
                            }
                        }
                    }
                })
                .addOnFailureListener(
                        new OnFailureListener() {
                            @Override
                            public void onFailure(@NonNull Exception e) {
                                // Task failed with an exception
                                // ...
                            }
                        });

从上面的侦听器中，我将获得所有文本的列表，请演示如何将文本设置为适当的字段
