android输出word文档

来源：互联网发布：简述什么是大数据时代编辑：程序博客网时间：2024/05/17 02:39

最近在项目工作中，碰到一个很棘手的需求，说是要在手机端根据模板生成word文档，而且不借助第三方的软件可以查看word文档，一开始听这个需求差不多蒙了，这要怎么做，为什么不把生成word文档这个工作放在后台呢，抱怨归抱怨，但是面对需求只能硬着头皮做了，经过各种拷问度娘和谷哥，终于找了一个比较好用的方法。特此跟他家分享。

Apache 公司推出的 Apache POI，我们来看下他的介绍：Apache POI 是用Java编写的免费开源的跨平台的Java API，Apache POI提供API给Java程式对Microsoft Office格式档案读和写的功能。

废话少说开始编码，首先我们要下Apache POI的开发jar包，下载地址：http://poi.apache.org/download.html，这里推荐不要下最新版本的，因为一开始我用最新版本的会出一下莫名其妙的问题，后面换旧的版本就OK了。这里我用的是3.9的还是比较稳定的、

开发有2个包，有一点我就非常郁闷Apache居然没有提供api稳定，开发起来还是比较蛋疼的，可能是我自己没有找到把，如果有知道的筒子可以@我、嘿嘿。不过Apache还是提供了Demo大家可以参考。还有我们要准备我们使用的word模板文件、这里我们放在了assets下面了。首先我们来看看怎么使用模板：

上面代码的代码并不多，首先我们要注意的是我们使用的poi的api大部分是在org.apache.poi.hwpf下面的，大家不要导错包了，因为apache每个包对应的内容不同：

上面代码不难懂，就是把我们要放的内容使用特定的代号组装一个map塞到我们的模板里面去，然后重新存储下，不过我们模板也要使用相同的代号、poi才能识别：

这样我们就使用模板大功告成了，就可以查看了、但是有些手机并没有装wps类似的工具，要是手机可以直接查看那就好了，嘿嘿、当然apache肯定也想到了、提供了这样的api下面上代码：

上面的代码的原理起始也很简单，poi提供了让word文档转换成html页面的方法、我们只需要使用webview来加载这个html就ok了，这样我们就可以再手机端直接查看我们的word文档了，是不是好强大。其实看起来的比较复杂的功能只要我们静下心来想想就没有我们想象中的那么复杂，今天就为大家分享到这了。下面有Demo的源码。
