有没有办法做到这一点？

没有。您可以添加到系统栏的唯一的事情是通知，这是不是意味着这种导航。

如果你指的是名为布局考虑拆分操作栏一节，这被称为裂操作栏，并能在一个启用＆LT;活性GT; 通过安卓uiOptions =splitActionBarWhenNarrow。然而，这只会采取 - 小 / -Normal 屏幕纵向效果。你的按钮会自动被放置在操作栏在其他情况下，屏幕的顶部。

I would like to override (add more buttons that would take me to several activities/fragments) to the system Navigation Bar on a tablet (according to this android ui-overview it is a "Combined bar" (for tablets) Is there a way to do this?

I couldn't find a Navigation class in the android.app package, like ActionBar.

If adding buttons to the combined/navigation bar is not possible, I think there are several options, but I'd like to explore this first: - use the action bar on top instead - add a bottom bar above the navigation bar (not really fine, since it would be on top of the combined bar), like they are showing here: Action Bar

Thanks a lot,
Cristian

Is there a way to do this?

No. The only thing you can add to the system bar are Notifications, which are not meant for this sort of navigation.

If adding buttons to the combined/navigation bar is not possible, I think there are several options, but I'd like to explore this first: - use the action bar on top instead - add a bottom bar above the navigation bar (not really fine, since it would be on top of the combined bar), like they are showing here: Action Bar

If you are referring to the section titled "Layout Considerations for Split Action Bars", that is referred to as a "split action bar", and can be enabled on an <activity> via android:uiOptions="splitActionBarWhenNarrow". However, that will only take effect for -small/-normal screens in portrait orientation. Your buttons will automatically be placed in the action bar at the top of the screen in other circumstances.
