I've realized eclipse IDE puts all packages in a project (at least in a Java one) at the same level, eg: 我已经意识到eclipse IDE将所有包放在同一级别的项目中（至少在Java中），例如：

同一级别的包裹

However, browsing the file system, you can find that packages are treated in the expected multi-levelled way. 但是，浏览文件系统，您可以发现以预期的多级方式处理包。 Does this have any logical explanation? 这有什么合理的解释吗？

This is just a presentation feature. 这只是一个演示功能。 You can click on the little down arrow you see on the left of your screen shot and select Package Presentation -> Hierarchical to have it like your filesystem. 您可以单击屏幕截图左侧看到的小向下箭头，然后选择Package Presentation - > Hierarchical以使其像文件系统一样。

I asked the same question a couple of times and found the link in above answer helpful in order to change the presentation because it's an option hard to find. 我问了几次同样的问题，发现上面的答案中的链接对于更改演示文稿很有帮助，因为这是一个很难找到的选项。

About the Why part, I think it's because of Eclipse being DE-facto standard IDE for Android development and having the packages organized this way is more useful and it forces you to think about a way your classes are organized according to Android project guidelines. 关于Why部分，我认为这是因为Eclipse是Android开发的事实上的标准IDE，并且以这种方式组织的包更有用，它迫使您根据Android项目指南考虑类的组织方式。 It also looks quite like help files on http://developer.android.com/guide to me personally. 对我个人来说，它看起来也像http://developer.android.com/guide上的帮助文件。 Also another argument for this might be that in old versions of Eclipse (pre Android time) default view was different. 另外一个论点可能是在Eclipse的旧版本（Android时间之前）默认视图不同。
