在android中创建PDF [英] Creating PDFs in android

问题描述

我正在使用此代码在android中生成pdf文件，但它给了我找不到文件异常

I am using this code to generate pdf file in android but it gives me "File not found exception"

            try {
    OutputStream file = new FileOutputStream(new File("D:\\Test.pdf"));

    Document document = new Document();
 //   PdfWriter.getInstance(document, new FileOutputStream(FILE));
    PdfWriter.getInstance(document, file);
    document.open();
    addMetaData(document);
    addTitlePage(document);
    addContent(document);
    //createImage();
    document.close();

} catch (Exception e) {
    e.printStackTrace();
}

：

    PdfWriter.getInstance(document, file);

它表示Java.io.FileNotFOundException。我必须创建新文件然后为什么打开一个甚至没有生成的文件？这段代码出了什么问题？

It says "Java.io.FileNotFOundException". I have to create new file then why is it open a file which is not even generated yet? what is wrong with this code?

推荐答案

我不认为D：\是android中的有效文件位置

I dont think "D:\" is a valid file location in android

尝试

OutputStream file = new FileOutputStream（newFile（Environment.getExternalStorageDirectory（）。toString ，test.pdf））;

如果你正在处理android中的文件系统，将来会有一些额外的信息，因为android是基于unix的路径分隔符是'/'而不是'\'。 '\'分隔符（据我所知）是Windows独有的东西，因为 D：

As a bit of extra info for in future if you are dealing with file systems in android, becasue android is unix based the path separator is '/' not '\'. The '\' separator is (as far as I know) something unique to windows as is D:
