Bottom Navigation Bar in Android

Bottom navigation bars allow movement between primary destinations in an app.

Usage

Bottom navigation bars display three to five destinations at the bottom of a screen. Each destination is represented by an icon and an optional text label. When a bottom navigation icon is tapped, the user is taken to the top-level navigation destination associated with that icon.

When to use

Bottom navigation should be used for:

• Top-level destinations that need to be accessible from anywhere in the app

• Three to five destinations

• Mobile or tablet only

Icons
