问题详情
目前了解到的读取 Word 文档的有三种形式：
1、直接调用第三方应用，如 WPS
2、使用 tm-extractors-0.4.jar
3、使用 poi
解决思路
使用第三方应用
这种查看内容效果时最好的，这个需要提示用户下载第三方，你可以写连接到应用市场的代码，也可以直接提示让用户自己下载
下载完成之后使用下面代码调用可以读取 doc 或 docx 文件的程序
Intent intent = getWordFileIntent(wordInfo.getPath());
try {
getContext().startActivity(intent);
}catch (Exception e) {
Toast.makeText(getContext(),"找不到可以打开该文件的程序",Toast.LENGTH_SHORT).show();
}
//android获取一个用于打开Word文件的intent
public static Intent getWordFileIntent(String param )
{
Intent intent = new Intent("android.intent.action.VIEW");
intent.addCategory("android.intent.category.DEFAULT");
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Uri uri = Uri.fromFile(new File(param ));
intent.setDataAndType(uri, "application/msword");
return intent;
}使用 tm-extractors-0.4.jar
这个显示效果比较简单，只能显示文字，图片、图表都不能显示
主要代码如下：
public String readWord(String file) {
// 创建输入流用来读取doc文件
FileInputStream in;
String text = null;
try {
in = new FileInputStream(new File(file));
WordExtractor extractor = null;
// 创建WordExtractor
extractor = new WordExtractor();
// 进行提取对doc文件
text = extractor.extractText(in);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return text;
}使用 poi
它的主要思路是将 word 文档转换成 html, 然后用 webview 显示，使用的需要两个 Jar 包 poi-3.15.jar，poi-scratchpad-3.15.jar
主要代码如下
