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、再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：

  1 public void FillPdfTemplate(String id) {
  2         android.icu.text.SimpleDateFormat simpleDateFormat =
  3                 new android.icu.text.SimpleDateFormat("HHmmss");// HH:mm:ss
  4         //设置默认时区
  5         simpleDateFormat.setTimeZone(android.icu.util.TimeZone.getTimeZone("GMT+8:00"));
  6         //获取当前时间
  7         Date date2 = new Date(System.currentTimeMillis());
  8         String sim2 = simpleDateFormat.format(date2);
  9
 10         String folderName_WaterImage = "WaterImage";
 11         String folderName_WaterDB = "WaterDB";
 12         String folderName_WaterPdf = "WaterPdf";
 13
 14         File sdCardDir_PdfTemplate = new File(Environment.getExternalStoragePublicDirectory(
 15                 Environment.DIRECTORY_DOWNLOADS), folderName_WaterDB);
 16         File sdCardDir_WaterPdf = new File(Environment.getExternalStorageDirectory(),
 17                 folderName_WaterPdf);
 18
 19         //模板路径
 20         String templatePath = sdCardDir_PdfTemplate + "/" + "WaterTemplate.pdf";
 21         //生成的新文件路径
 22         String newPDFPath = sdCardDir_WaterPdf + "/" +
 23                 mWaterInfo.SamplingDate + "_" + mWaterInfo.WellNumber + "_" + sim2 + ".pdf";
 24
 25 /**

 30         try {
