Difference between Tab Layout and ViewPager?

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

Regarding to the contradiction of using ViewPager

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?

TabLayout versus pagerTabStrip for convenience and functionality

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.

How to implement a horizontal scroll / swipe between Fragments?

I would like to achieve a navigation in my app like Pinterest or Trello, that is, kind of three tabs to navigation + horizontal scrolling.
I have made a custom tabbar for this (since I couldn't guess how to change tabs width in my actionbar with navigation TAB mode). So I have three buttons to navigate from one fragment to another. Now I would like to implement the horizontal scrolling like these two examples, to also navigate among my fragments.
I have read about View Pager but I don't know if it fits to my case, since I don't have only views but fragments. Does anybody have an example or an idea of how to do it? Could I apply it among different activities?
Thanks

Please take a look at the duplicate question that I just answered:
How to implement a swipe-gesture between Fragments?
I suppose the Android ViewPager is what you are looking for:
http://developer.android.com/reference/android/support/v4/view/ViewPager.html
Here is a nice tutorial on how to implement it:
http://developer.android.com/training/animation/screen-slide.html
The basic idea is that you have multiple Fragments, each representing
a different Screen. The ViewPager enables the user to swipe between
the different Fragments and display different content.

You can use ViewPager. More information about viewpager this.

Making one of the actionBar tabs have a view pager

I am trying to make an app to do the following function:
I need to have an ActionBar with 3 tabs such that one of the tabs has to implement a ViewPager and the other 2 tabs has to have separate layouts.Although I know how to create an ActionBar with Tabs with fragments, I am not sure how to(or if it is even possible) to implement a ViewPager inside one of the tabs.Thanks a lot for your help.
Edit:Nvm I found the solution.You have to use nested fragments.For more information refer to
