推荐答案

好的。你说你不想使用外部库？那么，有兴趣编写自己的库来解析和渲染PDF文件。您可能需要查看 SumatraPDF 的来源[ ^ ]了解您所从事的工作量。



就个人而言，我不会浪费6个月的时间来编写PDF库，因为有大量的PDF库已经存在并为我做这项工作。

OK. You say you don't want to use external libraries? Well then, have fun writing your own library to parse and render a PDF file. You might want to look at the source for SumatraPDF[^] to get an idea of the amount of work you're in for.

Personally, I wouldn't waste 6 months of my life writing a PDF library when there are a ton of them that already exist and do that job for me.

您好，



您可以在Android中使用WebView控件。

如果您在活动中声明它，您可以使用Google文件助手在里面。



YourWebViewControl.loadUrl（https://docs.google.com/gview?embedded=true&url=+ yourUrl）;



只需在网址前添加此行：



https://docs.google.com/gview ？embedded = true&url =



它还可以打开word文件，excel等。



希望我会帮你的。请告诉我。

Hello,

You can use WebView control in Android.
If you declare it in your Activity you can use Google Docs helper inside it.

YourWebViewControl.loadUrl("https://docs.google.com/gview?embedded=true&url=" + yourUrl);

Just simply add this line before url address:

"https://docs.google.com/gview?embedded=true&url="

It can also open word files, excel, etc.

Hope it will help. Let me know.
