I added a TabLayout to my layout XML, and instead of the classic ViewPager, I just have one NestedScrollView. My problem is when I try to change tabs depending on the position of the page (e.g., OnScrollChangeListener), I use tabLayout.getTabAt(3).select();, but it screws up the tabs before it.
Any tabs before the 4th tab (getTabAt(3) == 4th tab) become unselectable. When I click it, it just selects the 4th tab.

I have a Fragment which contains a TabLayout with a ViewPager. These tabs are 3 different Fragments. The problem is that when I am in the first tab for example and I press the TAB button on an external keyboard or using Vysor app, the focus moves through the different tabs but the user still sees the first tab. Is it possible to keep the focus on the tab that the user is viewing or change tabs as the focus moves?
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.
You can check here for tablaout without viewPager
TabLayout without using ViewPager
I need to handle the scrolling behaviour in my app. I have a screen with Colloapsing toolbar and tablayout viewpager. In this tablayout i have 3 tables.
First tab is content description. Second Tab and Thired Tab contains the List items.
Here the content of description and the list items is small i want to disable the appbar scrolling for each tab. If the content is large or list item is larger have to enable the appbar scrolling. Can any one know how to handle this..
I have a ViewPager with 4 tabs. One of the tabs has a RecyclerView and I want to be able to scroll to the top of the fragment/RecylerView when I press on the the current fragments tab.
How can I accomplish this?
I have implemented android appcompat actionbar with swipeable tab views using viewpager. I have set two tabs (two fragments). On first fragment (First tab) , I have a button click listener. In this button click listener I need to show the second tab. Though I can swipe between the tabs, I want to call second tab on button click in first tab. How to achieve this?
Well, I found the solution.
On button click listener in first tab,
I set actionBar.setSelectedNavigationItem(1);
This takes me to the second tab :)
