How to use TabLayout with ViewPager2 in Android

Question

I want to use com.google.android.material.tabs.TabLayout component with Android\'s new ViewPager implementation androidx.viewpager2.widget.Vi

Answer 1

Initialize the TabLayoutMediator object with an object of TabLayout, ViewPager2 , autoRefresh -- boolean type, and an object of OnConfigurationChangeCallback.

TabLayoutMediator tabLayoutMediator = new TabLayoutMediator(tabLayout, viewPager2, true, new TabLayoutMediator.OnConfigureTabCallback() {
  @Override
  public void onConfigureTab(TabLayout.Tab tab, int position) {
    // position of the current tab and that tab  
  }
});

Finally just call attach() to the TabLayoutMediator object to wire up the tablayout to the viewpager :-

 tabLayoutMediator.attach();

autoRefresh - key if set to true -- ( By default its set to true )

RECREATES all the tabs of the tabLayout if notifyDataSetChanged is called to the viewpager adapter.

Use the contents of TabLayoutMediator.java
