List FieldTypes = form.getFields();
    PDField pdfFields;
        for (int i = 0; i < FieldTypes.size(); i++) {

            pdfFields = (PDField) FieldTypes.get(i);
            String type = null;

            if (pdfFields instanceof PDTextbox) {
                type = "TextBox";
                String iAsString = Integer.toString(i);
                pdfFields.setValue(iAsString);
                System.out.println("Text" + "   "+ pdfFields.getFullyQualifiedName());
             } else if (pdfFields instanceof PDCheckbox) {
                type = "CheckBox";
                String iAsString = Integer.toString(i);
                System.out.println(iAsString);
                System.out.println("CheckBox" + "   "+ pdfFields.getFullyQualifiedName());
            } else if (pdfFields instanceof PDRadioCollection) {

                List kids = pdfFields.getKids();
                for (Object kid : kids) {
                      if (kid instanceof PDCheckbox) {
                      PDCheckbox checkbox = (PDCheckbox) kid;
                      String Name = checkbox.getOnValue();
                      String iAsString = Integer.toString(i);
                      System.out.println(iAsString);
                      type = "RadioButton";
                      System.out.println("RadioButton"+"  "+checkbox.getOnValue());
                      }

                }
            }
        }

Answer 1

Based on doc i think getOnValue() method returns only the status like checked or not checked. Can you try getPartialName(),getValue(),getFullyQualifiedName(),getAlternateFieldName() or any other methods.

Answer 2

With Radio Buttons you have to figure out what the "On Values" are, similar to a Checkbox. However there are multiple On values for Radio Buttons, so its a different method.

For example, if I run this against a Radio Button group where you have to choose from Checking Savings or Money Market, we would see this printed:

Type of Account (org.apache.pdfbox.pdmodel.interactive.form.PDRadioButton)

Radio Button

[Savings, Checking, Money Market]

public void list(PDField field)
{
    System.out.println(field.getFullyQualifiedName() + " (" + field.getClass().getName() +")");

    if(field instanceof PDRadioButton){
        System.out.println("Radio Button");
        System.out.println(((PDRadioButton) field).getOnValues());
    }
}

If I wanted to have the "Checking" button checked, I would set the field's value equal to "Checking".

Hopefully this helps.
