I am facing another issue in RadioButton. when click on unselected radio
button appearance of radio will disappear.
Sample PDF is attached and sample code I am using as follow:
try
{
PDDocument document = new PDDocument();
PDPage page = new PDPage(PDRectangle.A4);
document.addPage(page);
PDAcroForm acroForm = new PDAcroForm(document);
// not needed, we have appearance streams
//acroForm.setNeedAppearances(true);
acroForm.setXFA(null);
document.getDocumentCatalog().setAcroForm(acroForm);
PDFont font = PDType1Font.HELVETICA;
PDResources res = new PDResources();
COSName fontName = res.add(font);
acroForm.setDefaultResources(res);
acroForm.setDefaultAppearance('/' + fontName.getName() + "
10 Tf 0 g");
PDPageContentStream contents = new
PDPageContentStream(document, page);
List<String> options = Arrays.asList("a", "b", "c");
PDRadioButton radioButton = new PDRadioButton(acroForm);
radioButton.setPartialName("RadioButtonParent");
// removed per advice of Maruan Sahyoun, setValue didn't
work
anymore
//radioButton.setExportValues(options);
radioButton.getCOSObject().setName(COSName.DV, options.get(1));
radioButton.setFieldFlags(49152);
int on = 1;
List<PDAnnotationWidget> widgets = new ArrayList<>();
for (int i = 0; i < options.size(); i++)
{
PDAppearanceCharacteristicsDictionary fieldAppearance
=
new PDAppearanceCharacteristicsDictionary(new
COSDictionary());
fieldAppearance.setBorderColour(new PDColor(new
float[]
{ 0, 0, 0 }, PDDeviceRGB.INSTANCE));
PDAnnotationWidget widget = new PDAnnotationWidget();
widget.setRectangle(new PDRectangle(30, 811 - i * (21),
16, 16));
widget.setAppearanceCharacteristics(fieldAppearance);
widget.setAnnotationFlags(4);
widget.setPage(page);
PDAppearanceDictionary appearance =
widget.getAppearance();
if (appearance == null)
{
appearance = new PDAppearanceDictionary();
}
COSDictionary aeDict = new COSDictionary();
COSStream onStream = new COSStream();
aeDict.setItem(options.get(i), onStream);
aeDict.setItem(COSName.Off.getName(), onStream);
PDAppearanceEntry ae = new PDAppearanceEntry(aeDict);
appearance.setNormalAppearance(ae);
widget.setAppearance(appearance);
widgets.add(widget);
page.getAnnotations().add(widget);
widget.setAppearanceState(i == on? options.get(i):
"Off");
widgets.add(widget);
page.getAnnotations().add(widget);
contents.beginText();
contents.setFont(font, 10);
contents.newLineAtOffset(56, 811 - i * (21) + 4);
contents.showText(options.get(i));
contents.endText();
}
radioButton.setWidgets(widgets);
acroForm.getFields().add(radioButton);
contents.close();
try (FileOutputStream output = new
FileOutputStream("D:\\test22.pdf"))
{
document.save(output);
}
document.close();
}
catch (IOException e)
{
e.printStackTrace();
}
Please help me resolve this issue. Is any other configuration or
appearance I have to add.
Thanks,
Bharat

Thank a lot for details.
I tried with |widget.setAppearanceState(i ==on
?options.get(i):"Off");| and its works fine for me.
Thanks,

To select a button, the appropriate line there is
|widget.setAppearanceState(i ==on ?options.get(i):"Off");|
setValue should also work, but you'd have to delete this line
radioButton.setExportValues(options);
because there's a bug related to that.
Your code below seems to be based on an older answer of mine
(it has "new PDRadioButton" twice), which wasn't really good.
Another strategy would be that you open your created file with
PDFDebugger, then do the same after selecting something in
Adobe Reader and saving it.

Hi,
I used PDRadioButton to create group of radio button. I am
trying to select
the one radio button by default but radio button is not
appearing as
selected.
Code example as follows:
try
{
PDDocument document = new PDDocument();
PDPage page = new PDPage(PDRectangle.A4);
document.addPage(page);
PDAcroForm acroForm = new
PDAcroForm(document);
acroForm.setNeedAppearances(true);
acroForm.setXFA(null);
document.getDocumentCatalog().
setAcroForm(acroForm);
PDFont font = PDType1Font.HELVETICA;
PDResources res = new PDResources();
COSName fontName = res.add(font);
acroForm.setDefaultResources(res);
acroForm.setDefaultAppearance('/' +
fontName.getName() + " 10
Tf 0 g");
PDPageContentStream contents = new
PDPageContentStream(document, page);
List<String> options = Arrays.asList("a",
"b", "c");
PDRadioButton radioButton = new
PDRadioButton(acroForm);
radioButton.setPartialName("Ra
dioButtonParent");
radioButton.setExportValues(options);
radioButton.getCOSObject().set
Name(COSName.DV,
options.get(1));
List<PDAnnotationWidget> widgets = new
ArrayList<>();
for (int i = 0; i < options.size(); i++)
{
PDRadioButton subRadioButtons = new
PDRadioButton(acroForm);
subRadioButtons.setPartialName("RadioButton");
PDAppearanceCharacteristicsDictionary fieldAppearance =
new
PDAppearanceCharacteristicsDictionary(new
COSDictionary());
fieldAppearance.setBorderColour(new PDColor(new float[] {
0, 0, 0 }, PDDeviceRGB.INSTANCE));
PDAnnotationWidget widget =
subRadioButtons.getWidgets().get(0);
widget.setRectangle(new PDRectangle(30,
811 - i * (21), 16,
16));
widget.setAppearanceCharacteristics(fieldAppearance);
PDAppearanceDictionary appearance =
widget.getAppearance();
if (appearance == null)
{
appearance = new
PDAppearanceDictionary();
}
COSDictionary aeDict = new
COSDictionary();
COSStream on = new COSStream();
aeDict.setItem(options.get(i), on);
String value = null;
if (options != null)
{
value = options.get(i);
if (!"b".equalsIgnoreCase(value))
{
aeDict.setItem(COSName.Off.ge
<http://COSName.Off.ge>tName(), on);
}
}
PDAppearanceEntry ae = new
PDAppearanceEntry(aeDict);
appearance.setNormalAppearance(ae);
widget.setAppearance(appearance);
widgets.add(widget);
page.getAnnotations().add(widget);
contents.beginText();
contents.setFont(font, 10);
contents.newLineAtOffset(56, 811 - i * (21) + 4);
contents.showText(options.get(i));
contents.endText();
}
radioButton.setWidgets(widgets);
acroForm.getFields().add(radioButton);
contents.close();
try (FileOutputStream output = new
FileOutputStream("D:\\RadioTest.pdf"))
{
document.save(output);
}
document.close();
}
catch (IOException e)
{
e.printStackTrace();
}
How to make radio button "b" as selected?
Thanks,
Bharat
