iText不设置复选框字段 [英] iText doesn't set checkbox field
问题描述
我正在使用iText库生成基于模板的pdf文件。但是当我尝试设置复选框字段时,它将不会填充。
等级在这里:
I'm using iText library to generate pdf file based on template. But when I try to set checkbox field it won't filled. Class is here:
public class MainClass {
public static void main(String[] args) {
try {
PdfReader reader = new PdfReader("pdf/fw9_template.pdf");
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream("test.pdf"));
AcroFields form = stamper.getAcroFields();
String states[] = form.getAppearanceStates("topmostSubform[0].Page1[0].FederalClassification[0].c1_1");
System.out.println(states);
for (Iterator i = form.getFields().keySet().iterator(); i.hasNext(); ) {
String key = (String) i.next();
System.out.print(key + " : ");
switch(form.getFieldType(key)) {
case AcroFields.FIELD_TYPE_CHECKBOX:
System.out.println("Checkbox");
break;
case AcroFields.FIELD_TYPE_COMBO:
System.out.println("Combobox");
break;
case AcroFields.FIELD_TYPE_LIST:
System.out.println("List");
break;
case AcroFields.FIELD_TYPE_NONE:
System.out.println("None");
break;
case AcroFields.FIELD_TYPE_PUSHBUTTON:
System.out.println("Pushbutton");
break;
case AcroFields.FIELD_TYPE_RADIOBUTTON:
System.out.println("Radiobutton");
break;
case AcroFields.FIELD_TYPE_SIGNATURE:
System.out.println("Signature");
break;
case AcroFields.FIELD_TYPE_TEXT:
System.out.println("Text");
break;
default:
System.out.println("?");
}
}
form.setField("topmostSubform[0].Page1[0].FederalClassification[0].c1_1[0]", "true");
stamper.close();
} catch (Exception e) {
System.out.println(e);
}
}
}
程序输出:
null
topmostSubform[0].Page1[0].EmployerID[0].f1_14[0] : Text
topmostSubform[0].Page1[0].FederalClassification[0].f1_4[0] : Text
topmostSubform[0].Page1[0].f1_9[0] : Text
topmostSubform[0].Page1[0].f1_10[0] : Text
topmostSubform[0].Page1[0].FederalClassification[0].c1_1[1] : Checkbox
topmostSubform[0].Page1[0].f1_2[0] : Text
topmostSubform[0].Page1[0].EmployerID[0].f1_15[0] : Text

topmostSubform[0].Page1[0].Address[0].f1_8[0] : Text
topmostSubform[0].Page1[0].Address[0].f1_7[0] : Text
topmostSubform[0].Page1[0].FederalClassification[0].c1_1[0] : Checkbox
topmostSubform[0].Page1[0].FederalClassification[0].c1_1[2] : Checkbox
topmostSubform[0].Page1[0].FederalClassification[0].c1_7[0] : Checkbox
topmostSubform[0].Page1[0].FederalClassification[0].c1_1[4] : Checkbox
topmostSubform[0].Page1[0].FederalClassification[0].c1_1[3] : Checkbox
topmostSubform[0].Page1[0].f1_1[0] : Text
topmostSubform[0].Page1[0].FederalClassification[0].c1_1[5] : Checkbox
topmostSubform[0].Page1[0].SSN[0].f1_11[0] : Text
topmostSubform[0].Page1[0].FederalClassification[0].f1_3[0] : Text
topmostSubform[0].Page1[0].Exemptions[0].f1_6[0] : Text
topmostSubform[0].Page1[0].Exemptions[0].f1_5[0] : Text
我不明白为什么方法getAppearanceStates()返回'null',当我们在输出中看到复选框时。复选框也没有填写结果pdf文件。
I don't understand why the method getAppearanceStates() returns 'null', when we can see checkboxes in the output. Also checkbox doesn't filled in a result pdf file.
有人可以帮我解决这个问题吗?
Can anybody help me to resolve this issue?

Thanks in advance, Sergey
推荐答案
为什么状态
当你这样做时,结果是 null
:
Why does status
turns out to be null
when you do:
String states[] = form.getAppearanceStates(
"topmostSubform[0].Page1[0].FederalClassification[0].c1_1");
您在自己的问题中提供答案:因为没有名称<$ c $的字段c>表格中的topmostSubform [0] .Page1 [0] .FederalClassification [0] .c1_1。
You are providing the answer in your own question: because there is no field with name "topmostSubform[0].Page1[0].FederalClassification[0].c1_1"
in your form.
什么是<$当您使用以下行时,c $ c>州:
String states[] = form.getAppearanceStates(
"topmostSubform[0].Page1[0].FederalClassification[0].c1_1[1]");
