Can i add more than 5 menu items in bottom navigation view?

Question

我试图在底部导航视图中添加超过 5 个项目，但它导致膨胀错误。

Answer 1

According to Google's Material Design specification, BottomNavigationView does not support more than 5 items. You can use another library for BottomNavigationView since you can't achieve this with Google's library.

Create a menu resource with up to 5 navigation targets (BottomNavigationView does not support more than 5 items).

Secondly, Having 5 or more items in BottomNavigation is a bad design in terms of User Experience. Even 4 is a stretch. If you need more than 5 items, BottomNavigation is not suitable for you.

Answer 2

According to Material Design Specification, it is a bad practice to use more than 5 menu items for BottomNavigationView . Since, it is used to show only 3 to 5 top-level destinations(not related to same subject but of equal importance) , I suggest you to use Navigation Drawer instead. Also, I would only recommend you to use Tab Layout with ViewPager , if the destinations are connected to a common subject.

To illustrate it further, let's assume there is a Pill Reminder app. The related destinations can be Pending , Completed and/or Missed which are related in a way that they all show status of all Reminder at a point of time. To show these information, I would use ViewPager with TabLayout .
For other destinations such as Settings , Nearby Pharmacies , etc. which are top-level, I would use NavigationDrawer .

如果你想要，那么你可以采用水平线性布局，采用水平滚动，然后采用你喜欢的文本视图或按钮。
