I am working on an app where I want to add tabs so that can be added using
TabLayout with ViewPager.
It looks same to me with no difference but I guess there is some difference between them so they are two classes for this. So what is the main difference between them?
Just comparing the visuals…
TabLayout is a material concept that replaced the deprecated ActionBar tabs in Android 5.0.
HorizontalScrollView, so you can keep adding tabs horizontally which can include text, icons, or custom views and scroll through them linearly without paging.
TabLayout provides the
setupWithViewPager(ViewPager viewPager) method to attach to a
ViewPager instead of being part of the
ViewPager like the
PagerTabStrip is more of an indictor for the current page of a ViewPager, and “it is intended to be used as a child view of a ViewPager widget”. The scrolling for it does not act like the
TabLayout since each tab is part of the page instead of individually horizontally scrollable.
In summary, the differences are (apart from visuals).
TabLayoutis part of the Activity/Fragment, outside of the
ViewPager, and you instead attach it to one. It scrolls separately from the pages.
PagerTabStripis a child element of the
ViewPager. The tabs scroll with the page.
From the Developer.android I can say that the TabLayout is the material design concept and as all knows it’s new concept than the PagerTabStrip.
You can check the base hierarchy for both
1) TabLayout Hirarchy
java.lang.Object ↳ android.view.View ↳ android.view.ViewGroup ↳ android.widget.FrameLayout ↳ android.widget.HorizontalScrollView ↳ android.support.design.widget.TabLayout
2) PagerTabStrip Hirarchy
java.lang.Object ↳ android.view.View ↳ android.view.ViewGroup ↳ android.support.v4.view.PagerTitleStrip ↳ android.support.v4.view.PagerTabStrip
