I have implemented a view pager within a Coordinator layout that contains a ListFragment. The view pager is working fine but the list does not scroll,
can anyone help? Do I have to implement something to recognise the direction of the touch and then disable touch events?
Coordinator Layout:

I had the same result with the same issue, i just had to used these custom layouts, you may want to take a look:

I made the Toolbar and TabLayout transparent. In TabLayout, I have two fragments with RecyclerView.
When I scroll, the contents of the recyclerView do not go under the tolbar. Please tell me how to fix.
I use the behaviour but it seems not working

You should use this behavior in root of that view that want to place below of AppBarLayout, not in child of views (Fragments)
just add this behavior to ViewPager
just change :
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="112dp"
android:background="#color/transparent" />
to :
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="112dp"
android:background="#color/transparent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
I am trying to create a screen with coordinator layout that includes:
Toolbar
Fragment, which will be replaced for every page using navigation API
Bottom App bar
However, I am struggling with positioning views in a way so the app's bottom bar doesn't overlap what in the fragment.
Any chance you could help me out with this, please? From what I can tell, the only way is to add a margin at the bottom but this may not be consistent across devices.
To illustrate, this list has a total of 25 items but the last two are overlapped by the app's bottom bar.

You can use LinearLayout inside CoordinatorLayout to arrange your views if it fits your needs or ConstraintLayout
I hope that the basis of the decision is clear. Take a look at this example:

Trying to build layout in which the activity has Coordinator layout and Appbar layout. The appbar layout has tab layout, which is connected to a view pager. In the view pager, the first fragment has another coordinator layout and an appbar layout. When the scroll happens in appbar layout, I want the Activity's appbar layout also to scroll.

When the appbar scrolls in the fragment, I want the activity's appbar to scroll also.
I have used the NestedCoordinatorLayout as suggested in CoordinatorLayout inside another CoordinatorLayout
Please let me know how to achieve that
Thanks!
Followed this link Overlap scrolling view with AppBarLayout but overlapping doesn't seems to work well.Here i'm attaching my layout files with the output that i got.

Please have a look and give me your suggestion where i'm wrong.
By removing android:background="#android:color/white" from my custom layout and changing the CollapsingToolBar as app:layout_scrollFlags="scroll|enterAlwaysCollapsed",I resolved the issue.
I have recently migrated my listview to recyclerview, so that I could have the effect on the toolbar that disappear to show only tabs / RecyclerView.
Thing is now, when I try to align an element to bottom, that element is getting out of the screen from the bottom.
I have to add like 60dp of margin bottom to fix it.
But in my FloatingActionButton, those 60dp affect animation, so I don't like it so much...
Does anyone know the trick???
Here is my code:
First Tab
<?xml version="1.0" encoding="utf-8"?>

Any Idea???
