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) {
        android.icu.text.SimpleDateFormat simpleDateFormat =
                new android.icu.text.SimpleDateFormat("HHmmss");// HH:mm:ss
        //设置默认时区
        simpleDateFormat.setTimeZone(android.icu.util.TimeZone.getTimeZone("GMT+8:00"));
        //获取当前时间
        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 File(Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_DOWNLOADS), folderName_WaterDB);
        File sdCardDir_WaterPdf = new File(Environment.getExternalStorageDirectory(),
                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";

/**
