Render PDF forms on Android
The following section assumes you’re familiar with forms. If not, first see the introduction to forms guides for more details.
Form support in Nutrient
PSPDFKit supports all form types listed in the PDF specification.
| Type | Field object | Annotation object |
|---|---|---|
| Check, radio, and push buttons | ButtonFormField |
ButtonFormElement |
| List and combo boxes | ChoiceFormField |
ChoiceFormElement |
| Text | TextFormField |
TextFormElement |
| Signatures | SignatureFormField |
SignatureFormElement |
We differentiate between field objects and annotation objects; field objects have no visual representation of their own and are represented by FormField, while annotation objects are visual representations of a single control inside a form field and are represented by FormElement.
Disabling All Form Interactions
You can disable all form interactions and modifications using [formEditingEnabled(false)][]:
val builder = PdfActivityConfiguration.Builder(context) builder.formEditingEnabled(false)
PdfActivityConfiguration.Builder builder = new PdfActivityConfiguration.Builder(context); builder.formEditingEnabled(false);
Licensing
PDF Forms is a separate component in your PSPDFKit license. Without this feature included in your license, your app won’t be able to view or interact with PDF forms. Please contact our Sales team to add this feature to your license, or use a trial license if you want to try out this feature.
Signature form fields and signature form elements require that your license includes either Electronic Signatures or Digital Signatures, or that your license was originally obtained in April 2021 or earlier. If none of these requirements are met, then signature elements will be omitted, and other form elements will be shown.
