When using a ViewPager, is there any advantage to using TabLayout instead of PagerTabStrip or vice versa? Or are they equivalent? Is one more convenient than the other? Does one offer greater functionality? Again all questions are asked, and thus all answers are expected, in the context of ViewPager. Thanks.
TabLayout is a material concept that replaced the deprecated ActionBar tabs in Android 5.0.
It extends 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.
A 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.

I'm learning about tab layout because I need to use tab layout.
When i search for tab layout on Google, the one that comes up together is the view pager.
By the way, I'm not sure about the difference between tablayout and viewpager.
The tab layout has a menu at the top and screen switching is possible.
Although the view pager does not have tabs, it is possible to slide the screen just like the tab layout.
But why use the two together?
What's different?
Isn't it possible to slide in tab layout as well?
Yes, you can use TabLayout without viewPager. But without viewpager you won't be able to slide your page. You have to handle tabselect listener manually using this method then you have to click on the tab to navigate.
addOnTabSelectedListener(OnTabSelectedListener)
Likewise, you can use only Viewpager then you will be able to slide or swipe your page without any tabs.
From official doc
TabLayout
TabLayout provides a horizontal layout to display tabs.
Viewpager
Layout manager that allows the user to flip left and right through pages of data.
So Tablayout and viewpager are two different things but you can have the privilege of both tabs and slide only by combining them.

TabLayout without using ViewPager
Is it possible to create something similar to the PagerTitleStrip that existed in ViewPager? My intention is to just display titles for the fragments that are added without having a tabLayout.
To be specific I want to animate the tabs and not the ViewPager fragments.
I am having trouble deciding how to build this. Whether to use a separate scrollview or this can be achieved with TabLayout with some customizations.
Goal
Change the size of tab based on selection.
Change the size of tab based on position.
My idea is to use custom tabs & change the size using TabLayout.OnTabSelectedListener methods onTabSelected & onTabUnselected. But I would like to know if there is any direct approach to get this effect. For example, parallax effect in CollapsingToolbar.
My question is in my activity or fragment, there are TabLayout and ViewPager. If I was to disable swipe of ViewPager by using a class called NonSwipeableViewPager. Then why should I bother to using ViewPager right from the start, I could have just use TabLayout to add tabs which is much more simpler.
What are the other advantages of using ViewPager even though the primary function of it which is Creating Swipe Views with Tabs is not needed?
Do Fragment layout must use framelayout? Which means can I use relative or liner layout instead of framelayout?
Last but not least, do I allowed to use ViewPager with the swipe disabled?
I'm familiar with nested fragments. I am using viewpager in a fragment. I have three tabs, and want them to fill width. Instead of actionbar tabs, I tried using
SlidingTabLayout, but it doesn't fill width.
PagerTabStrip but the look doesn't suit my requirements
TabHost is too naive.
I'm ok to write my own tab layout if necessary but as it is heavily used, I don't think that is actually necessary. Please help me in this regard
