代码示例：

SparseArray<TextBlock> items = detections.getDetectedItems();
StringBuilder stringBuilder = new StringBuilder();
for (int i = 0; i < items.size(); ++i) {
    TextBlock item = items.valueAt(i);
    if (item != null && item.getValue() != null) {
        stringBuilder.append(item.getValue()+ " ," );
        ...
    }
}
