Adroid Itext学习文档（一）创建PDF

什么也不说,先上代码.

创建PDF

1.创建Document

   Document document = new Doucment(PageSize.A4,50,50,50,50);

2.创建PDFWriter

   PdfWriter writer = PdfWriter.getInstance(document,new FileOutputStream(android.os.Environment.getExternalStorageDirectory() + File.separator + "droidtext"+File.separator+"hellowd.pdf";

3.打开Document

  document.open();

4.写内容.很多种方式

5.关闭Document

  document.close()

代码如下：

Document document = new Document(PageSize.A4, 50, 50, 50, 50);

//判断文件夹是否存在

java.io.File file = new  java.io.File(android.os.Environment.getExternalStorageDirectory() +  java.io.File.separator + "droidtext");

if (!file.exists()) {

    file.mkdir();

}

PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(android.os.Environment.getExternalStorageDirectory() + java.io.File.separator + "droidtext" + java.io.File.separator + "hellowd.pdf"));

document.open();            

document.close();
