Android根据pdf模板⽣成pdf⽂件
我们需要⽣成⼀些固定格式的pdf⽂件或者⼀些报表数据，那么我们可以⽤ iText包去做。
需要包含的jar包：iText-5.0.6.jar iTextAsian.jar ，怎样jar包导⼊⼯程，在这⾥就不再赘述了，可⾃⾏⽹上搜索。
1、在word⾥建⽴⼀个表单，也就是你的pdf模板格式
2、把word保存为pdf格式
3、⽤迅捷pdf编辑器打开保存的pdf
保存pdf为模板，取名名字“PdfTemplate”（随便取名）。以下是代码部分：
public void FillPdfTemplate(String id) {
SimpleDateFormat simpleDateFormat =
SimpleDateFormat simpleDateFormat =
new SimpleDateFormat("HHmmss");// HH:mm:ss
//设置默认时区
simpleDateFormat.tTimeZone(android.icu.TimeZone("GMT+8:00"));
//获取当前时间
人工智能的未来Date date2 = new Date(System.currentTimeMillis());
String sim2 = simpleDateFormat.format(date2);
String folderName_WaterImage = "WaterImage";
String folderName_WaterDB = "WaterDB";
String folderName_WaterPdf = "WaterPdf";
File sdCardDir_PdfTemplate = new ExternalStoragePublicDirectory(
Environment.DIRECTORY_DOWNLOADS), folderName_WaterDB);
File sdCardDir_WaterPdf = new ExternalStorageDirectory(),
folderName_WaterPdf);
//模板路径
String templatePath = sdCardDir_PdfTemplate + "/" + "WaterTemplate.pdf";
//⽣成的新⽂件路径
String newPDFPath = sdCardDir_WaterPdf + "/" +
mWaterInfo.SamplingDate + "_" + mWaterInfo.WellNumber + "_" + sim2 + ".pdf";
/**
* 使⽤中⽂字体
* 如果是利⽤ AcroFields填充值的不需要在程序中设置字体，在模板⽂件中设置字体为中⽂字体就⾏了

BaFont bf = null;
try {从零开始多少字
bf = ateFont("STSong-Light", "UniGB-UCS2-H", BaFont.NOT_EMBEDDED);
} catch (DocumentException e) {

}
Font FontChine = new Font(bf, 12, Font.NORMAL);
PdfReader reader;
FileOutputStream out;
ByteArrayOutputStream bos;
PdfStamper stamper;
try {
out = new FileOutputStream(newPDFPath);//输出流
reader = new PdfReader(templatePath);//读取pdf模板
bos = new ByteArrayOutputStream();
stamper = new PdfStamper(reader, bos);

}
