本来是要在Android端生成doc的(这需求...),最后方法没有好的方法能够在Android上做到完美,最后还是只能搬迁到服务器。不浪费,还是记录下各框架不支持Android的原因以及他们的特点。Java相关的这类框架还是很多的,有几个还不错,可惜要么不支持Android,要么要收费还价格不低。
经过亲自测试,Android不支持Java的awt很多包不能直接在Android上用,FreeMarker挺不错的,能生成复杂漂亮的doc,可惜不支持Android。用POI在Android上能运行,但是一路因为版本,格式等走了很多坑,用WFS打开还是乱码。Jword、Aspose.word能完美支持,Jword试用期只有30天两者收费都不菲。itext没有测试,不过听说也不支持Android。
方法一:freemarker
该方法需要先手动创建一个doc模板(图片记得使用占位符),并保存为xml文件。通过动态替换特定标签${}中的内容生成。example:

xml文件太长,就不贴了...
最后附上Android不能使用的原因:http://*.com/questions/25929542/use-freemarker-library-in-android
补充关于动态显示list以及换行的问题
需求明确到:在上面的扣分项中,如果我有几条扣分项,我希望每显示一条换行。
直接在要显示的内容上加换行符,并没有什么效果,起不到换行的作用。
其中在加ftl标签时,如<#list></list>,就会出现一些问题,在xml中并不识别,导致项目不能运行。
解决:
在需要显示多条扣分项的位置加,并加换行符:
<#list firstDeductItem as firstItem>
<w:t>${firstItem}</w:t><w:br/>
</#list>
TestDoc.java中改为:
List<String> Strs=new ArrayList<String>();
Strs.add("1111111111111111111");
Strs.add("222222222222222");
Strs.add("333333333333333");
dataMap.put("firstDeductItem", Strs);
DocUtil.java中改为:
//定义Template对象,注意模板类型名字与downloadType要一致
template=configure.getTemplate(downloadType+".ftl");此时xml文件会报错,当然也不能编译运行项目,需要将.xml文件改为.ftl文件保存。再编译运行,效果图:
方法二:POI
用这个方法遇到了很多版本问题,这里是基于POI3.7+Word2007的,测试能够完美运行。
你需要用Word2007手动生成文档模板(用其他的生成会报错:无法打开文件),并用${}替换需要动态更新的内容,与上面类似,但是不需要你保存为xml文档格式了。
