已采纳

jacob和poi一样的,只不过poi不依赖office软件,jacob依赖;而jacob可以做图片的显示,这个要比poi强大一些,而且poi更出名些.

这个是先开始读取sdcard的目录,用LIstview显示,如果你只需要一个Button点击进入的话,就直接传一个文件名用Bundle带参传值过去就好了。。

你好,我对android不太熟,但是对于java解析pdf,我刚做了一个相关的项目。
建议你学习一下xpdf,和icepdf,这些都是比较好的抽取文本的程序,但是我认为抽取pdf都会有偏差的,对于里面的表格一类的不好弄。
相对于你说的word,excel相对来说网上的资料比较多一点了,比较容易一点。

我也是在做用poi显示word和excel的内容。
目前我已经做到了支持office2003的标准,因为2007之后加入了ooxml之后比较麻烦,poi也是在ooxml纳入国际文档标准后才开始支持新版本的。
针对doc文件,poi里面支持的包是hwpf
真的对docx文件,poi里面的包是xwpf
可恶的是hwpf包里面有convert可以直接从doc转换成html。而xwpf里面没有
目前我的思路是docx文件转成doc文件,然后用doc的converter
或者是docx转换为标准的document文件(或者xml格式),然后用document转换为html
我也还是新手,你那边有解决方案说一下
