Android TabLayout

TabLayout is used to implement horizontal tabs. TabLayout is released by Android after the deprecation of ActionBar.TabListener (API level 21).

TabLayout is introduced in design support library to implement tabs.

Tabs are created using newTab() method of TabLayout class. The title and icon of Tabs are set through setText(int) and setIcon(int) methods of TabListener interface respectively. Tabs of layout are attached over TabLayout using the method addTab(Tab) method.

We can also add tab item to TabLayout using TabItem of android design widget.
