How to use scrollView in Tabbed Activity - Android?

Question

Does anyone know how you can use ScrollView in a fragment using the Tabbed Activity Template when creating a new activity. It uses a viewPager by default, and I've made 3 tabs with 3 different layouts which I can slide through. But every time i try to use the ScrollView in any one of these tabs the program gets buggy and nothing happens, sometimes i can't even swipe. So, in different words:

My Question: What is the proper way to use scrollview in a tab(fragment) when using the default tabbed activity template with ViewPager?

UPDATE 1

The thing with NestedScrollView worked, but now this is the new problem that came along with the solution. The AppBar scrolls along with the other stuff. How can i fix this?

UPDATE 2

It looks like the scrollView has an effect on this type of AppBar (Toolbar to be more specific), and i just fixed the problem by adding app:layout_scrollFlags="enterAlwaysCollapsed" to <android.support.v7.widget.Toolbar/>, and it's now stationary.

For reasons that might seem unclear to most of us, it is hard for touch events to be differentiated when you want to scroll vs swipe.

To solve this, I used a NestedScrollView instead of the regular ScrollView.

The other option would be to catch the events and override them - obviously more complicated to do but possible.

You can take a look at my recent code on github for an example.

Good luck and please let me know if it works for you!

Well, thanks for the answer! It worked, but partially. Now the whole action bar with the tabs is moving when I scroll up and down. Any idea why is that, and how to fix it? I'm gonna see what i can do, and if I find a fix, I'll give you the updates. Just to add, i havent done anything different to the default template by android, that's why I'm not uploading any code. – Теодор Митев Oct 06 '16 at 16:26
