在iText上填写复选框 [英] Fill in checkbox on iText

问题描述

我正在尝试使用iText修改现有PDF。我的代码目前很好地编辑了文本字段，但我无法勾选或取消选中复选框。

I am trying to modify an existing PDF with iText. My code currently edits text fields nicely, but I cant get it to tick or un-tick a checkbox.

                PdfReader reader = new PdfReader(INPUTFILE);
                int n = reader.getNumberOfPages();

                PdfStamper filledOutForm = new PdfStamper(reader, new FileOutputStream("WrittenForm.pdf"));

                AcroFields fields = filledOutForm.getAcroFields();

                //not working
                fields.setField("checkbox", "On");

                //working
                fields.setField("textfield1", "infinite road");
                fields.setField("textfield2", "jayboy");


                filledOutForm.close();

任何想法？

求助：

 String states[] = fields.getAppearanceStates("checkbox");

//prints array values - returns 'yes, no'

 System.out.println(Arrays.toString(states));

推荐答案

因为我在这里点击，您需要使用以下方式检查可用状态：

As I saw here, you need to check the available states using:

String[] states = fields.getAppearanceStates("checkbox");

然后根据 String [] <中的选项设置状态/ code>

And then set the state according to the options in this String[]
